ICD-10-CM has 21 chapters ICD-9-CM has 17 chapters

ICD-10-CM incorporates “V” and “E” codes into the main classification ICD-9-CM has supplemental classifications for “V” and “E”

codes ICD-10-CM groups injuries first by specific site (e.g.,

head, arm, leg), and then by type of injury (e.g., fracture, open wound) ICD-9-CM groups injuries by type first then by specific site

ICD-10-CM incorporates postoperative complications into procedure-specific body system chapters ICD-9-CM has a separate chapter for postoperative

complications ICD-10-CM has added a placeholder X

Page 6: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

There are now two sets of guidelines ICD-10-CM Official Guidelines for Coding and Reporting ICD-10-PCS Coding Guidelines

ICD-10-CM follows the same format as ICD-9-CM; Conventions for ICD-10-CM General Guidelines Chapter Specific Guidelines Selection of Principal Diagnosis Reporting Additional Diagnosis Diagnostic Coding & Reporting for Outpatient Services Present On Admission (POA)

Page 7: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

“Adherence to these guidelines when assigning ICD-10-CM diagnosis codes is required under the Health Insurance Portability and Accountability Act (HIPAA). The diagnosis codes (Tabular List and Alphabetic Index) have been adopted under HIPAA for all healthcare settings.”

7

Page 8: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

“The importance of consistent, complete documentation in the medical record cannot be overemphasized. Without such documentation accurate coding cannot be achieved. The entire record should be reviewed to determine the specific reason for the encounter and conditions treated.”

8

Page 9: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Conventions for the ICD-10-CM are the general rules for use of the classification independent of the guidelines. These conventions are incorporated within the Alphabetic Index and Tabular List of the ICD-10-CM as instructional notes. These conventions and instructions take

precedence over guidelines.

9

Page 10: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

The Alphabetic Index and Tabular List Alphabetic Index• Alphabetical list of terms and their corresponding

code Index of Diseases and Injury Index of External Causes of Injury Neoplasm Table Table of Drugs and Chemicals

Tabular List• Structured list of codes divided into chapters based

on body system or condition

10

Page 11: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Format and Structure: ICD-10-CM Tabular List contains Categories,

Subcategories and Codes Categories are 3 characters• If a 3 character category has no further subdivision it is

equivalent to a code Subcategories are either 4 or 5 characters• Each level of subdivision after a category is a subcategory

Codes can be 3, 4, 5, 6, or 7 characters• All codes must be assigned to the highest subdivision or it

would not be considered a code Use of Codes for Reporting Purposes:

For reporting purposes only codes are permissible, not categories or subcategories, and any applicable 7th character is required

11

Page 12: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Placeholder Character ICD-10-CM utilizes a placeholder which is always

the letter X and has two uses;• As the fifth character for certain six character codes.

The X provides for future expansion without disturbing the sixth character structure

Example: S06.0X1A• When a code has less than six characters and a

seventh character is required. The X is assigned for all characters less than six in order

to meet the requirement of coding the highest level of specificity

Example: O65.0XX1

12

Page 13: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

7th Characters A 7th character can be used to provide further

specificity about the condition being coded 7th characters may be a number or letter 7th characters must always be used as the seventh

character Example: Category M80 requires one of the

following 7th charactersA - initial encounter for fractureD - subsequent encounter for fracture with routine healingG - subsequent encounter for fracture with delayed healingK - subsequent encounter for fracture with nonunionP - subsequent encounter for fracture with malunionS - sequela

13

Page 14: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Alphabetic Index abbreviations NEC “Not elsewhere classifiable”• This abbreviation represents “other specified”. When

a specific code is not available for a condition, the Alphabetic Index directs the coder to the “other specified” code in the Tabular List.

NOS “Not otherwise specified”• This abbreviation is the equivalent of unspecified.

Tabular List abbreviations NEC “Not elsewhere classifiable” NOS “Not otherwise specified”

14

Page 15: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Punctuation [ ] Brackets are used in the Tabular List to enclose

synonyms, alternative wording or explanatory phrases. Brackets are used in the Alphabetic Index to identify manifestation codes.

( ) Parentheses are used in both the Alphabetic Index and Tabular List to enclose supplementary words that may be present or absent in the statement of a disease or procedure without affecting the code number to which it is assigned. The terms within the parentheses are referred to as nonessential modifiers.

: Colons are used in the Tabular List after an incomplete term which needs one or more of the modifiers following the colon to make it assignable to a given category.

15

Page 17: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Other and Unspecified codes “Other” codes• Use codes titled “other” or “other specified” when

the information in the medical record provides detail for which a specific code does not exist.

“Unspecified” codes• Use codes titled “unspecified” when the information

in the medical record is insufficient to assign a more specific code.

17

Page 18: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Includes Notes Used in the Tabular List Appears under a three character code title Further defines, or give examples of, the content

of the category• Example

K25 Gastric UlcerIncludes: erosion (acute) of stomach

pylorus ulcer (peptic) stomach ulcer (peptic)

18

Page 19: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Inclusion Terms Used in the Tabular List Are a list of conditions that the particular code is

used for The terms may be synonyms of the code title, or

in the case of “other specified” codes the terms are a list of the various conditions assigned to that code

Not necessarily an exhaustive list, additional terms found only in the Alphabetic Index may also be assigned to a code

At the code level the word “includes” does not precede the list of terms included in the code

19

Page 20: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Inclusion Terms Example• K31.5 Obstruction of duodenum

Constriction of duodenum Duodenal ileus (chronic) Stenosis of duodenum Stricture of duodenum Volvulus of duodenum

20

Page 21: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Excludes Notes ICD-10-CM has two types of excludes notes. Each type

of note has a different definition. Excludes 1

A pure excludes note “Not Coded Here” This note is used when two conditions cannot occur

together, such as a congenital form versus an acquired form of the same condition

Example• K51.4 Inflammatory polyps of colon

Excludes 1: adenomatous polyp of colon (D12.6) polyposis of colon (D12.6) polyps of colon NOS (K63.5)

21

Page 22: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Excludes 2 Represents “Not Included Here” The condition excluded is not part of the condition

represented by the code, but a patient may have both conditions at the same time

It is acceptable to use both the code and the excluded code together if the patient has both conditions

Example• J37.1 Chronic laryngotracheitis

Excludes 2: acute laryngotracheitis (J04.2) acute tracheitis (J04.1)

22

Page 23: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Etiology/manifestation convention (”code first”, “use additional code” and “in diseases classified elsewhere” notes) Etiology codes are always sequenced first and will

include a “use additional code” note Manifestation codes will include a “code first”

note “Code first” and “Use additional code” notes are

also used as sequencing rules in the classification for certain codes that are not part of the etiology/manifestation combinations

23

Page 24: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

“And” The word “and” should be interpreted to mean either

“and” or “or” when it appears in a title “With”

The word “with” should be interpreted to mean “associated with” or “due to” when it appears in a code title, the Alphabetic Index or an instructional note in the Tabular List

“See” and “See Also” The term “see” following a main term in the Alphabetic

Index indicates that another term should be referenced The “see also” instruction following a main term in the

Alphabetic Index instructs that there is another main term that may also be referenced that may provide additional entries that may be useful

24

Page 25: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

25

Page 26: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Default codes A code listed next to a main term in the ICD-10-

CM Alphabetic Index is referred to as a default code

Default codes represent that condition that is most commonly associated with the main term, or is the unspecified code for the condition• Example

Appendicitis without any additional information, such as acute or chronic defaults to K37 Appendicitis (pneumococcal) (retrocecal) K37 K37 Unspecified appendicitis

26

Page 27: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Locating a code in the ICD-10-CM First locate the term in the Alphabetic Index, and

then verify the code in the Tabular List Selection of the full code, including any 7th

character and laterality can only be done in the Tabular List

The Alphabetic Index entry includes a dash (-) at the end of a subcategory to indicate that additional characters are required

Example• Bursitis, elbow NEC M70.3-

Requires a 6th character to specify laterality

27

Page 28: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Level of Detail in Coding Diagnosis codes are to be used and reported at

their highest number of characters available ICD-10-CM diagnosis codes are composed of

codes with 3, 4, 5, 6, or 7 characters A code is invalid if it has not been coded to the

full number of characters required for the code, including the 7th character, if applicable

28

Page 29: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Code or codes from A00.0 through T88.9, Z00-Z99.8 The appropriate code or codes from A00.0

through T88.9, Z00-Z99.8 must be used to identify diagnoses, symptoms, conditions, problems, complaints or other reason(s) for the encounter/visit

Signs and Symptoms Codes that describe symptoms and signs, as

opposed to diagnoses, are acceptable for reporting purposes when a related definitive diagnosis has not been established (confirmed) by the provider

29

Page 30: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Conditions that are an integral part of a disease process Signs and symptoms that are associated routinely

with a disease process should not be assigned as additional codes, unless otherwise instructed by the classification

Conditions that are not an integral part of a disease process Additional signs and symptoms that may not be

associated routinely with a disease process should be coded when present

30

Page 31: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Multiple coding for a single condition In addition to the etiology/manifestation

convention that requires two codes, there are other single conditions that also require more than one code • “Use additional code”, “code first” and “code, if

applicable, any causal condition first” notes are used to provide guidance when more than one code may be necessary to completely code a condition

• Example E36.8 Other intraoperative complications of endocrine

system Use additional code, if applicable, to further specify

disorder

31

Page 32: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

32

Page 33: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Combination Code A combination code is a single code used to classify:• Two diagnoses, or• A diagnosis with an associated secondary process

(manifestation), or• A diagnosis with an associated complication

Combination codes are identified by referring to subterm entries in the Alphabetic Index and by reading the inclusion and exclusion notes in the Tabular List

Assign only the combination code when that code fully identifies the diagnostic conditions involved or when the Alphabetic Index so directs.• Example

E11.40 Type 2 diabetes mellitus with diabetic neuropathy, unspecified

33

Page 34: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sequela (Late Effects) ICD-10-CM always uses the term “Sequela” rather

than late effect The guideline itself is unchanged with the

exception of adding reference to specific guidelines for sequela of specific body systems• See Section I.C.9 Sequela of cerebrovascular disease• See Section I.C.15 Sequela of complication of

pregnancy, childbirth and the puerperium• See Section I.C.19 Application of 7th characters for

Chapter 19

34

Page 35: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sequela (Late Effects) A sequela is the residual effect (condition produced)

after the acute phase of an illness or injury has terminated • The code for the acute phase of an illness or injury that led

to the sequela is never used with a code for the late effect There is no time limit on when a sequela code can be

used Coding of sequela generally requires two codes

sequenced in the following order:• The condition or nature of the sequela is sequenced first• The sequela code is sequenced second

35

Page 36: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Impending or Threatened Condition Code any condition documented on discharge as

“impending” or “threatened” as follows:• If it did occur, code as a confirmed diagnosis• If it did not occur, reference the Alphabetic Index to

determine if the condition has a subentry term for “impending” and for “threatened” and also reference main term entries for “impending” and for “threatened” If the subterms are listed, assign the given code If the subterms are not listed, code the existing

underlying condition(s) and not the condition described as impending or threatened

36

Page 37: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Reporting Same Diagnosis Code More Than Once Each unique ICD-10-CM diagnosis code may be

reported only once for an encounter• This applies to bilateral conditions when there are no

distinct codes identifying laterality or• Two different conditions classified to the same ICD-

10-CM diagnosis code

37

Page 38: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Laterality Some ICD-10-CM codes indicate laterality, specifying

whether the condition occurs on the left, right or bilateral

If no bilateral code is provided and the condition is bilateral, assign separate codes for both the left and right side

If the side is not identified in the medical record, assign the code for the unspecified side

Example• Swimmer’s ear

H60.331 Swimmer’s ear, right ear H60.332 Swimmer’s ear, left ear H60.333 Swimmer’s ear, bilateral H60.339 Swimmer’s ear, unspecified ear

38

Page 39: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Documentation for BMI, Non-pressure Ulcers and Pressure Ulcer Stages BMI, depth of non-pressure chronic ulcers and pressure

ulcer stage codes can be assigned based on medical record documentation from clinicians who are not the patient’s provider• The associated diagnosis (overweight, obesity, pressure

ulcer) must be documented by the patient’s provider The BMI codes should only be reported as secondary

diagnoses. As with all other secondary diagnosis codes, the BMI codes should only be assigned when they meet the definition of a reportable additional diagnosis

39

Page 40: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Syndromes Follow the Alphabetic Index guidance when

coding syndromes In the absence of Alphabetic Index guidance,

assign codes for the documented manifestations of the syndrome

Additional codes for manifestations that are not an integral part of the disease process may also be assigned when the condition does not have a unique code

40

Page 41: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Documentation of Complications of Care Code assignment is based on the provider’s

documentation of the relationship between the condition and the care or procedure• Not all conditions that occur during or following

medical care or surgery are classified as complications

This guideline applies to any complications of care, regardless of the chapter the code is located in

There must be a cause and effect relationship between the care provided and the condition, and an indication in the documentation that it is a complication

41

Page 42: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Borderline Diagnosis If the provider documents a “borderline”

diagnosis at the time of discharge, the diagnosis is coded as confirmed, unless the classification provides a specific entry (e.g., borderline diabetes)

If a borderline condition has a specific index entry in ICD-10-CM, it should be coded as such

Borderline conditions are not uncertain diagnoses, therefore there is no distinction between the care setting (inpatient versus outpatient)• Example

Hypertension Borderline R03.0

42

Page 43: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

In addition to general coding guidelines, there are guidelines for specific diagnoses and/or conditions in the classification. Unless otherwise indicated, these guidelines apply to all health care settings

21 Chapters instead of 17 Eyes and Ears are now separate chapters External Causes of Morbidity Factors influencing health status and contact with

health services

43

Page 44: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Human Immunodeficiency Virus (HIV) Infections Code only confirmed cases of HIV infection/illness Selection and sequencing of HIV codes• If a patient is admitted for an HIV-related condition,

the principal diagnosis should be B20, followed by additional diagnosis codes for all reported HIV-related conditions

• If a patient with HIV disease is admitted for an unrelated condition, the code for the unrelated condition should be the principal diagnosis. Other diagnoses would be B20 followed by additional diagnosis codes for all reported HIV-related conditions

44

Page 45: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Human Immunodeficiency Virus (HIV) Infections Selection and sequencing of HIV codes• Whether the patient is newly diagnosed or has had

previous admissions/encounters for HIV conditions is irrelevant to the sequencing decision

• Asymptomatic HIV infection status (Z21) is to be applied when the patient without any documentation of symptoms is listed as being “HIV positive”, “known HIV”, “HIV test positive”, or similar terminology. Do not use Z21if the term “AIDS” is used or if the patient is treated for any HIV-related illness or is described as having any condition(s) resulting from his/her HIV positive status; use B20 in these cases.

45

Page 46: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Human Immunodeficiency Virus (HIV) Infections Selection and sequencing of HIV codes• Inconclusive HIV serology, but no definitive diagnosis or

manifestations of the illness, may be assigned code R75, Inconclusive laboratory evidence of HIV

• Patients with any known prior diagnosis of an HIV-related illness should be coded to B20

• During pregnancy, childbirth or the puerperium, a patient admitted (or presenting for a health care encounter) because of an HIV-related illness should receive a principal diagnosis code of O98.7-, HIV disease complicating pregnancy, childbirth and the puerperium, followed by B20 and the code(s) for the HIV related illness(es).

46

Page 47: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Human Immunodeficiency Virus (HIV) Infections Selection and sequencing of HIV codes• If a patient is being seen to determine his/her HIV

status, use code Z11.4, encounter for screening for HIV

• If a patient with signs or symptoms is being seen for HIV testing, code the signs and symptoms. An additional counseling code Z71.7 HIV counseling, may be used if counseling is provided

• When a patient returns to be informed of his/her HIV test results and the test result is negative, use code Z71.7, HIV counseling. If the results are positive, see previous guidelines and assign codes as appropriate

47

Page 48: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Human Immunodeficiency Virus (HIV) Infections

Coding Examples HIV positive male is seen for diagnostic tests

which results in a diagnosis of Pneumocystis pneumonia• B20 Human Immunodeficiency Virus (HIV) Disease• B59 Pneumocystosis

HIV seropositive• Z21 Asymptomatic human immunodeficiency virus

(HIV) infection status

48

Page 49: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Infectious agents as the cause of diseases classified to other chapters Certain infections are classified in chapters other

than Chapter 1 and no organism is identified as part of the infection code

An additional code from Chapter 1 should be used to identify the organism• B95, Streptococcus, Staphylococcus, and Enterococcus• B96, Other bacterial agents• B97, Viral agents

An instructional note will be found at the infection code advising that an additional organism code is required

49

Page 50: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Infectious agents as the cause of diseases classified to other chapters - continued

Coding Examples E. coli Urinary Tract Infection• N39.0 Urinary Tract Infection, site not specified• B96.20 Unspecified E coli as the cause of diseased

classified elsewhere Pseudomonas Pneumonia• J15.1 Pneumonia due to Pseudomonas

50

Page 51: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Infections resistant to antibiotics Many bacterial infections are resistant to current

antibiotics. It is necessary to identify all infections documented as antibiotic resistant. Assign a code from category Z16, Resistance to antimicrobial drugs, following the infection code only if the infection code does not identify drug resistance.

Example• C. Diff colitis resistant to ampicillin

A04.7 Enterocolitis due to Clostridium difficile Z16.11 Resistance to penicillins

51

Page 52: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sepsis, Severe Sepsis and Septic Shock Coding of Sepsis and Severe Sepsis• Sepsis

For a diagnosis of sepsis, assign the appropriate code for the underlying systemic infection. If the type of infection or causal organism is not further specified, assign code A41.9, sepsis, unspecified organism.

A code from subcategory R65.2, Severe sepsis, should not be assigned unless severe sepsis or an associated acute organ dysfunction is documented Negative or inconclusive blood cultures do not preclude a

diagnosis of sepsis in patients with clinical evidence of the condition, however, the provider should be queried

52

Page 53: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sepsis, Severe Sepsis and Septic Shock Coding of Sepsis and Severe Sepsis• Sepsis

The term urosepsis is a nonspecific term. It is not to be considered synonymous with sepsis. It has no default code in the Alphabetic Index. Should a provider use this term, he/she must be queried for clarification.

If a patient has sepsis and associated acute organ dysfunction or multiple organ dysfunction (MOD), follow the instructions for coding severe sepsis

If a patient has sepsis and an acute organ dysfunction, but the medical record documentation indicates that the acute organ dysfunction is related to a medical condition other than the sepsis, do not assign a code from subcategory R65.2, Severe sepsis. Acute organ dysfunction must be associated with sepsis in order to assign the Severe sepsis code. If documentation is unclear, query the provider.

53

Page 54: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sepsis, Severe Sepsis and Septic Shock Coding of Sepsis and Severe Sepsis• Severe Sepsis

The coding of severe sepsis requires a minimum of 2 codes: first a code for the underlying systemic infection, followed by a code from subcategory R65.2, Severe sepsis. If the causal organism is not documented, assign code A41.9, Sepsis, unspecified organism, for the infection. Additional code(s) for the associated acute organ dysfunction are also required

Due to the complex nature of severe sepsis, some cases may require querying the provider prior to assignment of the codes

54

Page 55: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sepsis, Severe Sepsis and Septic Shock Coding of Septic Shock• Septic shock generally refers to circulatory failure

associated with severe sepsis, and therefore, it represents a type of acute organ dysfunction.

• For cases of septic shock, the code for the systemic infection should be sequenced first, followed by code R65.21, Severe sepsis with septic shock or code T81.12, Postprocedural septic shock. Any additional codes for the other acute organ dysfunctions should also be assigned. As noted in the sequencing instructions in the Tabular List, the code for septic shock cannot be assigned as a principal diagnosis.

55

Page 56: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sepsis, Severe Sepsis and Septic Shock Sequencing of severe sepsis• If severe sepsis is present on admission, and meets the

definition of principal diagnosis, the underlying systemic infection should be assigned as principal diagnosis followed by the appropriate code from subcategory R65.2 as required by the sequencing rules in the Tabular List. A code from subcategory R65.2 can never be assigned as a principal diagnosis.

• When severe sepsis develops during an encounter (it was not present on admission) the underlying systemic infection and the appropriate code from subcategory R65.2 should be assigned as secondary diagnoses

56

Page 57: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sepsis, Severe Sepsis and Septic Shock Sequencing of severe sepsis• Severe sepsis may be present on admission but the

diagnosis not confirmed until sometime after admission. If the documentation is not clear whether severe sepsis was present on admission, the provider should be queried.

Sepsis and severe sepsis with localized infection• If the reason for admission is both sepsis or severe

sepsis and a localized infection, such as pneumonia or cellulitis, a code(s) for the underlying systemic infection should be assigned first and the code for the localized infection should be assigned as a secondary diagnosis

57

Page 58: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sepsis, Severe Sepsis and Septic Shock Sepsis due to a postprocedural infection• As with all postprocedural complications, code

assignment is based on the provider’s documentation of the relationship between the infection and the procedure

• The postprocedural infection code (such as T80.2, Infections following infusion, transfusion and therapeutic injection, or T81.4, Infection following a procedure) should be coded first, followed by the code for the specific infection. If severe sepsis is documented, the appropriate code from subcategory R65.2 should also be assigned with the additional code(s) for any acute organ dysfunction.

58

Page 59: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sepsis, Severe Sepsis and Septic Shock Sepsis due to a postprocedural infection• In cases where a postprocedural infection has

occurred and has resulted in severe sepsis and postprocedural septic shock, the code for the precipitating complication such as code T81.4, Infection following a procedure or O86.0, Infection of obstetrical surgical wound should be coded first followed by code R65.21, Severe sepsis with septic shock and a code for the systemic infection

59

Page 60: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sepsis, Severe Sepsis and Septic Shock Sepsis and severe sepsis associated with noninfectious

process (condition)• If sepsis or severe sepsis is documented as associated with

a noninfectious condition, such as a burn or serious injury, and this condition meets the definition for principal diagnosis, the code for the noninfectious condition should be sequenced first, followed by the code for the resulting infection

• If the infection meets the definition of principal diagnosis it should be sequenced before the noninfectious condition

• Only one code from category R65 should be assigned. Therefore, when a non-infectious condition leads to an infection resulting in severe sepsis, assign the appropriate code from subcategory R65.2, Severe sepsis. Do not additionally assign a code from subcategory R65.1 SIRS of noninfectious origin.

Methicillin susceptible Staphylococcus aureus (MSSA) and MRSA colonization Colonization means that MSSA or MSRA is present

on or in the body without necessarily causing illness. A positive MRSA colonization test might be documented by the provider as “MRSA screen positive” or “MRSA nasal swab positive”.

Assign code Z22.322, Carrier or suspected carrier of MRSA or Z22.321, Carrier or suspected carrier of MSSA

If both MRSA colonization and a MRSA infection are documented, a code for both the MRSA infection and MRSA colonization can be assigned

63

General Guidelines The neoplasm table should be referenced first.

However, if the histological term is documented, that term should be referenced first, rather than going immediately to the Neoplasm Table, in order to determine which column in the Neoplasm Table is appropriate

A primary malignant neoplasm that overlaps two or more contiguous sites should be classified to the subcategory/code .8 (‘overlapping lesion’), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous such as different quadrants of the same breast, codes for each site should be assigned.

64

Page 65: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

General Guidelines Malignant neoplasms of ectopic tissue are to be

coded to the site of origin mentioned, e.g., ectopic pancreatic malignant neoplasm involving the stomach is coded to pancreas, unspecified (C25.9)

Treatment directed at the malignancy If treatment is directed at the malignancy,

designate the malignancy as the principal diagnosis• Exception: if the admission/encounter is solely for

administration of chemotherapy, immunotherapy or radiation therapy, assign the appropriate Z51.–- code as the first-listed or principal diagnosis

65

Page 66: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Treatment of secondary site When treatment is directed toward a secondary

site only, the secondary neoplasm is designated as the principal diagnosis even though the primary malignancy is still present.

72

Page 73: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Primary malignancy previously excised When a primary malignancy has been previously

excised or eradicated from its site and there is no further treatment directed to that site and there is no evidence of any existing primary malignancy, a code from category Z85 (personal history of malignant neoplasm) should be used

Any mention of extension, invasion, or metastasis to another site is coded as a secondary malignant neoplasm to that site

73

Page 74: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Admissions/Encounters involving chemotherapy, immunotherapy and radiation therapy Episode of care involves surgical removal of

neoplasm• When an episode of care involves the surgical

removal of a neoplasm, primary or secondary site, followed by adjunct chemotherapy or radiation treatment during the same episode of care, the code for the neoplasm should be assigned as principal or first-listed diagnosis

74

Page 75: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Admissions/Encounters involving chemotherapy, immunotherapy and radiation therapy Admission/encounter solely for administration of

chemotherapy, immunotherapy and radiation therapy• If a patient admission/encounter is solely for the

administration of chemotherapy, immunotherapy or radiation therapy assign code Z51.0, Z51.11 or Z51.12 as the first-listed or principal diagnosis

• If a patient receives more than one of these therapies during the same admission more than one of these codes may be assigned, in any sequence

Admission/encounter to determine extent of malignancy When the reason for admission/encounter is to

determine the extent of the malignancy, or for a procedure such as paracentesis or thoracentesis, the primary malignancy or appropriate metastatic site is designated as the principal or first-listed diagnosis, even though chemotherapy or radiotherapy is administered

77

Page 78: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Symptoms, signs, and abnormal findings listed in Chapter 18 associated with neoplasms Symptoms, signs, and ill-defined conditions listed

in Chapter 18 characteristic of, or associated with, an existing primary or secondary site malignancy cannot be used to replace the malignancy as principal or first-listed diagnosis, regardless of the number of admissions or encounters for treatment and care of the neoplasm

78

Page 79: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Malignancy in two or more noncontiguous sites A patient may have more than one malignant

tumor in the same organ. These tumors may represent different primaries or metastatic disease, depending on the site. Should the documentation be unclear, the provider should be queried as to the status of each tumor so that the correct codes can be assigned

79

Page 80: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Disseminated malignant neoplasm, unspecified Code C80.0, Disseminated malignant neoplasm,

unspecified, is for use only in those cases where the patient has advanced metastatic disease and no known primary or secondary sites are specified. It should not be used in place of assigning codes for the primary site and all known secondary sites.

Malignant neoplasm without specification of site Code C80.1, Malignant (primary) neoplasm,

unspecified, equates to Cancer, unspecified. This code should only be used when no determination can be made as to the primary site of a malignancy. This code should rarely be used in the inpatient setting.

80

Page 81: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sequencing of neoplasm codes Encounter for treatment of primary malignancy• If the reason for the encounter is for treatment of a

primary malignancy, assign the malignancy as the principal-first listed diagnosis. The primary site is to be sequenced first, followed by any metastatic sites.

Encounter for treatment of secondary malignancy• When an encounter is for a primary malignancy with

metastasis and treatment is directed toward the metastatic (secondary) site(s) only, the metastatic site(s) is designated as the principal-first listed diagnosis. The primary malignancy is coded as an additional code.

Sequencing of neoplasm codes Malignant neoplasm in a pregnant patient• When a pregnant woman has a malignant neoplasm, a

code from subcategory O9A.1-, Malignant neoplasm complicating pregnancy, childbirth, and the puerperium, should be sequenced first, followed by the appropriate code from Chapter 2 to indicate the type of neoplasm

Encounter for complication associated with a neoplasm• When an encounter is for management of a complication

associated with a neoplasm, such as dehydration, and the treatment is only for the complication, the complication is coded first, followed by the appropriate code(s) for the neoplasm (exception is anemia as we previously discussed)

82

Page 83: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sequencing of neoplasm codes Complication from surgical procedure for treatment of

a neoplasm• When an encounter is for treatment of a complication

resulting from a surgical procedure performed for the treatment of the neoplasm, designate the complication as the principal-first listed diagnosis. See guideline regarding the coding of a current malignancy versus personal history to determine if the code for the neoplasm should also be assigned.

Pathological fracture due to a neoplasm• When an encounter is for a pathological fracture due to a

neoplasm, and the focus of treatment is the fracture, a code from subcategory M84.5--, Pathological fracture in neoplastic disease, should be sequenced first, followed by the code for the neoplasm

83

Current malignancy versus personal history of malignancy When a primary malignancy has been excised but further

treatment such as an additional surgery for the malignancy, radiation therapy or chemotherapy is directed to that site, the primary malignancy code should be used until treatment is completed

When a primary malignancy has been previously excised or eradicated from its site, there is not further treatment directed to that site, and there is not evidence of any existing primary malignancy, a code from category Z85.- Personal history of malignant neoplasm, should be used to indicate the former site of the malignancy

84

Page 85: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Leukemia, Multiple Myeloma, and Malignant Plasma Cell Neoplasms in remission versus personal history The code categories for leukemia, multiple

myeloma, and malignant plasma cell neoplasms have characters indicating whether or not the leukemia has achieved remission. There are also codes for personal history of these types of neoplasms. If the documentation is unclear as to whether these types of neoplasms has achieved remission, the provider should be queried.

Mental and behavioral disorders due to psychoactive substance use In Remission• Selection of codes for “in remission” for categories

F10-F19, Mental and behavioral disorders due to psychoactive substance use requires the provider’s clinical judgment

• The provider must document that the condition is “in remission” to assign these codes

100

Page 101: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Mental and behavioral disorders due to psychoactive substance use Psychoactive Substance Use, Abuse and Dependence• When the provider documentation refers to use, abuse and

dependence of the same substance only one code should be assigned

• Use the following hierarchy to determine which code to assign If both use and abuse are documented, assign only the

abuse If both abuse and dependence are documented, assign only

the code for dependence If use, abuse and dependence are all documented, assign

only the code for dependence If both use and dependence are documented, assign only

the code for dependence

101

Dominant/Non-dominant side Certain code categories and subcategories

identify whether an affected side is dominant or non-dominant. (G81, G83.1, G83.2 or G83.3)

If the affected side is documented, but not specified as dominant or non-dominant, and the classification system does not indicate a default, code selection is as follows For ambidextrous patients, the default is dominant If the left side is affected, the default is non-dominant If the right side is affected, the default is dominant

104

Page 105: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Pain – Category G89 Category G89 may be used in conjunction with

codes from other categories and chapters to provide more detail about acute or chronic pain and neoplasm-related pain, unless otherwise indicated below• If the pain is not specified as acute or chronic, post-

thoracotomy, postprocedural, or neoplasm-related, do not assign codes from category G89

• A code from category G89 should not be assigned if the underlying (definitive) diagnosis is known, unless the reason for the encounter is pain control/management and not management of the underlying condition

105

Page 106: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Pain – Category G89 When an admission or encounter is for a

procedure aimed at treating the underlying condition (e.g., spinal fusion, kyphoplasty), a code for the underlying condition (e.g., vertebral fracture, spinal stenosis) should be assigned as the principal diagnosis. No code from category G89 should be assigned

106

Page 107: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

G89 as Principal or First-Listed Diagnosis When pain control or pain management is the

reason for the admission/encounter, the underlying cause of the pain should be reported as an additional diagnosis, if known• A patient with displaced intervertebral disc, nerve

impingement and severe back pain presents for injection of steroid into the spinal canal

When a patient is admitted for the insertion of a neurostimulator for pain control, assign the appropriate pain code as the principal or first-listed diagnosis

107

Page 108: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

G89 as Principal or First-Listed Diagnosis When an admission or encounter is for a

procedure aimed at treating the underlying condition and a neurostimulator is inserted for pain control during the same admission/encounter, a code for the underlying condition should be assigned as the principal diagnosis and the appropriate pain code should be assigned as a secondary diagnosis

108

Page 109: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

G89 Category codes with Site-Specific Pain Codes Codes from category G89 may be used in

conjunction with codes that identify the site of pain if the category G89 code provides additional information

Sequencing of category G89 codes with site-specific pain codes is dependent on the circumstances of the encounter/admission as follows: • If the encounter/admission is for pain control or pain

management, assign the code from category G89 followed by the code for the specific site of pain

109

Page 110: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

G89 Category codes with Site-Specific Pain Codes Example• Admission for pain management of acute neck pain

from trauma G89.11 Acute pain due to trauma M54.2 Cervicalgia to identify the site of pain

If the encounter is for any other reason except pain control or pain management and a related definitive diagnosis has not been established by the provider, assign the code for the specific site of pain first, followed by the appropriate code from category G89

110

Page 111: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Postoperative Pain The providers documentation should be used to

guide the coding of postoperative pain The default for post-thoracotomy and other

postoperative pain not specified as acute or chronic is the code for the acute form

Routine or expected postoperative pain immediately after surgery should not be coded

Postoperative pain not associated with a specific postoperative complication is assigned to the appropriate postoperative pain code in category G89

111

Page 112: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Postoperative Pain Postoperative pain associated with a specific

postoperative complication (such as painful wire sutures) is assigned to the appropriate code(s) found in Chapter 19. If appropriate, use additional code(s) from category G89 to identify acute or chronic pain (G89.18 or G89.28)

Chronic Pain Chronic pain is classified to subcategory G89.2.

There is no time frame defining when pain becomes chronic pain. The provider’s documentation should be used to guide use of these codes

112

Page 113: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Neoplasm Related Pain Code G89.3 is assigned to pain documented as related to,

associated with or due to cancer When the stated reason for admission/encounter is pain

control/pain management, G89.3 can be the first-listed or principal diagnosis

When the stated reason for the admission/encounter is management of the neoplasm and the pain associated with the neoplasm is also documented, code G89.3 may be assigned as an additional diagnosis

Chronic Pain Syndrome Central pain syndrome (G89.0) and chronic pain

syndrome (G89.4) are different than the term “chronic pain”, and therefore codes should only be used when the provider has specifically documented this condition

113

Page 114: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coding Examples Left-sided hemiplegia• G81.94 Hemiplegia, unspecified affecting left

Glaucoma Assign as many codes from category H40,

Glaucoma, as needed to identify the type of glaucoma, the affected eye, and the glaucoma stage

Bilateral Glaucoma same type and stage• When a patient has bilateral glaucoma and both eyes

are documented as being the same type and stage, and there is a code for bilateral glaucoma, report only the code for the type of glaucoma, bilateral, with the seventh character for the stage Example

H40.2130 Acute angle-closure glaucoma, bilateral, stage unspecified

115

Page 116: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Bilateral glaucoma with same type and stage When a patient has bilateral glaucoma and both

eyes are documented as being the same type and stage, and the classification does not provide a code for bilateral glaucoma, report only one code for the type of glaucoma with the appropriate seventh character for the stage

Example• H40.11x2 primary open-angle glaucoma, moderate

stage

116

Page 117: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Bilateral glaucoma stage with different types or stages When a patient has bilateral glaucoma and each

eye is documented as having a different type or stage, and the classification distinguishes laterality, assign the appropriate code for each eye rather than the code for bilateral glaucoma

Example• H40.1221 Low-tension glaucoma, left eye, mild stage • H40.1213 Low-tension glaucoma, right eye, severe

stage

Glaucoma and stage evolves during the admission If a patient is admitted with glaucoma and the

stage progresses during the admission, assign the code for highest stage documented

Indeterminate stage glaucoma Assignment of the seventh character “4”

“indeterminate stage” should be based on the clinical documentation. This stage is used when the stage cannot be clinically determined. This is different than unspecified which is used when there is no documentation regarding the stage of the glaucoma.

Hypertension No Hypertension Table Hypertension with Heart Disease• Heart conditions classified to I50.- or I51.4-I51.9, are

assigned to a code from category I11, Hypertensive heart disease, when a causal relationship is stated (due to hypertension) or implied (hypertensive)

Hypertensive Chronic Kidney Disease• Assign codes from category I12, Hypertensive

chronic kidney disease, when both hypertension and a condition classifiable to category N18, Chronic kidney disease, are present. ICD-10-CM presumes a cause and effect relationship

120

Page 121: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Hypertension Hypertensive Heart and Chronic Kidney Disease• Assign codes from combination category I13 when

both hypertensive kidney disease and hypertensive heart disease are stated in the diagnosis

Hypertensive Cerebrovascular Disease• For hypertensive cerebrovascular disease, first

assign the appropriate code from categories I60-I69, followed by the appropriate hypertension code

Hypertensive Retinopathy• Subcategory H35.0 should be used with a code from

category I10-I15 for the hypertension• Sequencing is based on the reason for the encounter

121

Page 122: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Hypertension, Secondary Secondary hypertension is due to an underlying

condition Two codes are required: one to identify the

underlying etiology and one from category I15 to identify the hypertension

Hypertension, Transient Assign code R03.0, Elevated blood pressure

reading without diagnosis of hypertension, unless the patient has an established diagnosis of hypertension

O13.- and O14.- are used for obstetric cases with transient hypertension

122

Page 123: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Hypertension, Controlled This diagnostic statement usually refers to an

existing state of hypertension under control by therapy

Assign the appropriate code from I10-I15Hypertension, Uncontrolled

Uncontrolled hypertension may refer to untreated hypertension or hypertension not responding to current therapeutic regimen

In either case assign the appropriate code from I10-I15

123

Atherosclerotic Coronary Artery Disease and Angina ICD-10-CM has combination codes for

atherosclerotic heart disease with angina pectoris When using one of these combination codes it is

not necessary to use an additional code for angina pectoris

A causal relationship can be assumed in a patient with both atherosclerosis and angina pectoris.

If a patient with coronary artery disease is admitted due to an acute myocardial infarction, the acute MI should be sequenced before the coronary artery disease

125

Page 126: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coding Examples: Coronary artery disease with angina pectoris• I25.119 Atherosclerotic heart disease of native

coronary artery with unspecified angina pectoris

Coronary artery disease with unstable angina• I25.110 Atherosclerotic heart disease of native

coronary artery with unstable angina pectoris

126

Page 127: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Intraoperative and Postprocedural Cerebrovascular Accident Medical record documentation should clearly

specify the cause-and–effect relationship between the medical intervention and the cerebrovascular accident in order to assign a code for intraoperative or postprocedural CVA

Proper code assignment depends on whether it was an infarction or hemorrhage and whether is occurred intraoperatively or postoperatively

If a cerebral hemorrhage, code assignment depends on the type of procedure performed

127

Page 128: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sequelae of Cerebrovascular Disease Category I69, Sequelae of Cerebrovascular disease• Category I69 is used to indicate conditions classifiable to

categories I60-I67 as the causes of sequelae (neurologic deficits), themselves classified elsewhere

Codes from category I69 that specify hemiplegia, hemiparesis and monoplegia • Sequelae specified as hemiplegia, hemiparesis and

monoplegia identify whether the dominant or nondominant side is affected. Should the affected side be documented, but not specified as dominant or nondominant and the classification system does not indicate a default, code selection is as follows: For ambidextrous patients, the default should be dominant. If the left side is affected, the default is nondominant. If the right side is affected, the default is dominant

128

Page 129: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sequelae of Cerebrovascular Disease Codes from category I69 with codes from I60-I67• Codes from I69 and I60-I67 can be assigned together

if the patient has a current cerebrovascular disease and deficits from an old cerebrovascular disease

Code Z86.73• Assign code Z86.73, Personal history of transient

ischemic attack (TIA) and cerebral infarction without residual deficits, as an additional code for history of cerebrovascular disease when no neurologic deficits are present.

• Codes from category I69 should not be assigned if the patient does not have neurologic deficits.

129

Page 130: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coding Examples History of cerebrovascular infarction with aphasia

and left sided hemiplegia of the non-dominate side• I69.320 Aphasia following cerebral infarction• I69.354 Hemiplegia and hemiparesis following

cerebral infarction affecting left non-dominant side

130

Page 131: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Acute Myocardial Infarction (AMI) ICD-10-CM codes for AMI identify the site, such as

anterolateral wall or true posterior wall. AMI are also identified by ST elevation myocardial infarction (STEMI) and non ST elevation myocardial infarction (NSTEMI) and nontransmural myocardial infarction.

If NSTEMI evolves to STEMI, assign the STEMI code. If STEMI converts to NSTEMI due to thrombolytic therapy, it is still coded as STEMI

131

Page 132: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Acute Myocardial Infarction (AMI) The timeframe for acute MI codes has changed

from 8 weeks or less to 4 weeks or less.• If an MI is 4 weeks old or less and still requires

continued care, codes from category I21 are used.• For encounters after the 4 week timeframe and the

patient is still receiving care related to the MI, the appropriate aftercare code should be assigned

• For old or healed myocardial infarctions not requiring further care, code I25.2, Old MI, may be assigned

132

Page 133: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Acute Myocardial Infarction, unspecified Code I21.3 ST elevation MI of unspecified site, is

the default for unspecified AMI. If only STEMI or transmural MI without the site is documented, assign code I21.3

AMI documented as nontransmural or subendocardial but site provided If an AMI is documented as nontransmural or

subendocardial, but the site is provided, it is still coded as a subendocardial AMI

133

Page 134: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Subsequent Acute MI A code from category I22, Subsequent ST

elevation (STEMI) and non ST elevation (NSTEMI) myocardial infarction is to be used when a patient who has suffered an AMI has a new AMI within the 4 week time frame of the initial AMI. A code from category I22 must be used in conjunction with a code from category I21. The sequencing of the I22 and I21 codes depends on the circumstances of the encounter.

134

Mild persistent Moderate persistent Severe persistent

136

Page 137: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Chronic Obstructive Pulmonary Disease (COPD) Acute exacerbation of chronic obstructive

bronchitis and asthma• Code categories J44 and J45 distinguish between

uncomplicated cases and those in acute exacerbation

• An acute exacerbation is a worsening or a decompensation of a chronic condition

• An acute exacerbation is not equivalent to an infection superimposed on a chronic condition, though an exacerbation may be triggered by an infection

137

Page 138: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Acute Respiratory Failure Acute respiratory failure or acute and chronic

respiratory failure may be assigned as a principal diagnosis when it is the condition established after study to be chiefly responsible for occasioning the admission to the hospital, and the selection is supported by the Alphabetic Index and Tabular List

Acute respiratory failure may be a secondary diagnosis if it occurs after admission, or if it is present on admission, but does not meet the definition of principal diagnosis

138

Influenza Due to Certain Identified Influenza Viruses Code only confirmed cases of influenza due to certain

influenza viruses (category J09) and due to other identified influenza virus (category J10)

“Confirmed” does not require documentation of positive laboratory testing, but should be based on provider’s diagnostic statement that the patient has avian influenza, or other novel influenza A, or has another particular identified strain of influenza

If “suspected”, “possible” or “probable” avian influenza or novel influenza, or other identified influenza is documented, then the appropriate influenza code from category J11, Influenza due to unidentified influenza virus, should be assigned

139

Page 140: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Ventilator Associated Pneumonia (VAP) As with all procedural or postprocedural

complications, code assignment is based on the provider’s documentation of the relationship between the condition and the procedure

Code J95.851, Ventilator associated pneumonia, (VAP) should be assigned only when the provider has documented VAP

If the documentation is unclear as to the relationship between the pneumonia and the mechanical ventilation, query the provider

Pressure Ulcer Stage Codes Codes from category L89, Pressure ulcer, are

combination codes that identify the site and laterality as well as the stage of the ulcer

Pressure ulcer stages are based on severity, which is designated by stages 1-4, unspecified stage and unstageable• The code for unstageable pressure ulcer is assigned

based on clinical documentation. The stage cannot be clinically determined

• The code for unspecified stage is assigned when there is no documentation of the stage of the pressure ulcer

143

Page 144: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Healed Pressure Ulcers No code is assigned if the documentation states

that the pressure ulcer is completely healedHealing Pressure Ulcers

Pressure ulcers described as healing are assigned the code for the pressure ulcer stage based on documentation in the medical record

If the documentation does not provide information on the stage of the healing pressure ulcer, assign the appropriate code for unspecified stage

144

Site and Laterality Most codes within chapter 13 have site and laterality

designations• Site represents the bone, joint or the muscle involved• For some conditions where more than one bone, joint or

muscle is involved there is a “multiple sites” code available

• When there is not a multiple sites option available codes should be assigned to indicate each site involved

Bone versus Joint• When a condition involves the upper or lower end of a

bone which may be at the joint, the site designation will be the bone not the joint

146

Coding for Pathological Fractures The following seventh characters are required • A initial encounter for fracture

Use “A” for as long as the patient is receiving active treatment for the fracture

• D subsequent encounter for fracture with routine healing Use “D” after active treatment has been completed

• G subsequent encounter for fracture with delayed healing• K subsequent encounter for fracture with nonunion• P subsequent encounter for fracture with malunion• S sequela

147

Page 148: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Osteoporosis without pathological fracture Category M81, Osteoporosis without current

pathological fracture, is for use for patients with osteoporosis who do not currently have a pathologic fracture due to the osteoporosis

If the patient has had a pathological fracture in the past due to osteoporosis code Z87.310, Personal history of (healed) osteoporosis fracture, should also be assigned

148

Page 149: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Osteoporosis with current Pathological Fracture Category M80, Osteoporosis with current

pathological fracture, is for patients who have a current pathological fracture at the time of an encounter

Codes under M80 identify the site of the fracture not the site of the osteoporosis

Traumatic fracture codes should not be used for any patient with known osteoporosis who suffers a fracture, even if the patient had a minor fall or trauma, if that fall or trauma would not usually break a normal, healthy bone

149

Chronic Kidney Disease (CKD) CKD is classified based on severity• Severity is designated by stages 1-5 and End Stage Renal

Disease (ESRD)• If both a stage of CKD and ESRD are documented, assign

code N18.6, ESRD CKD and Kidney transplant status• Patients who have had a kidney transplant may still have

some form of CKD because the transplant may not fully restore kidney function. Therefore, the presence of CKD alone does not constitute a transplant complication

• If a transplant complication such as failure or rejection is documented, see section I.C.19.g for coding complications of kidney transplant

General Rules for Obstetric Cases Obstetric cases require codes from chapter 15 Additional codes from other chapters may be used

in conjunction with chapter 15 codes to further specify conditions

If the provider documents that the pregnancy is incidental to the encounter, code Z33.1 should be used in place of any chapter 15 codes• It is the provider’s responsibility to state that the

condition(s) being treated is not affecting the pregnancy

Chapter 15 codes are used only on the maternal record, never on the newborn record

153

Page 154: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Final Character for Trimester The episode of care (delivered, antepartum,

postpartum) is no longer the axis of classification, but rather the trimester in which the condition occurred

A note at the beginning of the chapter 15 defines trimesters. Trimesters are counted from the first day of the last menstrual period• 1st trimester – less than 14 weeks 0 days• 2nd trimester – 14 weeks 0 days to less than 28

weeks 0 days• 3rd trimester – 28 weeks 0 days until delivery

154

Page 155: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Final Character for Trimester Assignment of the final character for trimester should

be based on the provider’s documentation of the trimester (or number of weeks) for the current admission/encounter

Whenever delivery occurs during the current admission, and there is an “in childbirth” option for the obstetric complication being coded, the “in childbirth” code should be assigned

Each category that includes codes for trimester has a code for “unspecified trimester”. The “unspecified trimester” code should rarely be used, such as when the documentation in the record is insufficient to determine the trimester and it is not possible to obtain clarification.

155

Page 156: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Final Character for Trimester When a patient is admitted to a hospital for

complications during one trimester and remains in the hospital into a subsequent trimester, assign the trimester 7th character based on the trimester the complication occurred, not the trimester at time of discharge

If the condition developed prior to the current admission/encounter or represents a pre-existing condition, the trimester character for the trimester at the time of the admission/encounter should be assigned

156

Page 157: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

7th character for Fetus Identification When applicable, a 7th character is to be assigned for

certain categories to identify the fetus for which the complication code applies

The code categories which require this 7th character include a note at the beginning of the code. The following are the 7th characters• 0 - not applicable or unspecified• 1 - fetus 1• 2 - fetus 2• 3 - fetus 3• 4 - fetus 4• 5 - fetus 5• 9 - other fetus

157

Page 158: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

The 7th character “0” is assigned for the following reasons; Single gestations When the documentation in the record is

insufficient to determine the fetus affected and it is not possible to obtain clarification

When it is not possible to clinically determine which fetus is affected

158

Page 159: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Selection of OB Principal or First-listed diagnosis Routine outpatient prenatal visits• Routine outpatient prenatal visits when no complications are

present, a code from category Z34 should be used• These codes should not be used with chapter 15 codes

Prenatal outpatient visits for high-risk patients• Routine outpatient prenatal visits for patients with high-risk

pregnancies, a code from category O09 should be used Secondary chapter 15 codes may be used in conjunction with these

codes if appropriate Episodes when no delivery occurs• When no delivery occurs during an episode of care, the

principal diagnosis should correspond with the principal complication of the pregnancy which necessitated the encounter

• When more than one complication exits, all of which are treated or monitored, any of the complication codes may be sequenced first

159

Page 160: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Selection of OB Principal or First-listed diagnosis Pre-existing conditions vs conditions due to the

pregnancy• When assigning codes from chapter 15 it is important to

determine if the condition was pre-existing prior to pregnancy or developed during or due to the pregnancy in order to assign the correct code

Pre-existing hypertension in pregnancy• Category O10, Pre-existing hypertension complicating

pregnancy, childbirth and the puerperium, includes codes for hypertensive heart and hypertensive CKD When assigning one of the O10 codes that includes

hypertensive heart or CKD it is necessary to add a secondary code from the appropriate hypertension category to specify the type of heart failure or CKD

160

Page 161: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Fetal Conditions Affecting the Management of the Mother Maternal care for known or suspected fetal

abnormality (O35 and O36)• Codes from categories O35 and O36 are assigned only

when the fetal condition is actually responsible for modifying the management of the mother

• The fact that the fetal condition exists does not justify assigning a code from this series to the mother’s record

In utero surgery• When surgery is performed on the fetus, a diagnosis code

from category O35 should be assigned• No code from Chapter 16 should be used on the mother's

record• Surgery performed in utero on a fetus is still to be coded as

an obstetric encounter

Sepsis and Septic Shock Complicating Abortion, Pregnancy, Childbirth and the Puerperium When sepsis complicates abortion, pregnancy,

childbirth and the puerperium, a code for the specific type of infection should be assigned as an additional diagnosis

If severe sepsis is present, a code from subcategory R65.2 should also be assigned

Puerperal Sepsis Code O85, Puerperal sepsis, should be assigned with a

secondary code to identify the causal organism If applicable, use additional codes to identify severe

sepsis (R65.2-) and any associated acute organ dysfunction

164

Alcohol and Tobacco use during pregnancy, childbirth and the puerperium Alcohol use• Codes in subcategory O99.31 are used for any pregnancy

case when a mother uses alcohol during the pregnancy or postpartum

• A secondary code from category F10 (alcohol related disorders) should also be used to identify manifestations of the alcohol use

Tobacco use• Codes in subcategory O99.33 are used for any pregnancy

case when a mother uses any type of tobacco product during pregnancy or postpartum

• A secondary code from category F17 (nicotine dependence) should also be assigned to identify the type of nicotine dependence

165

Page 166: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Poisoning, Toxic Effects, Adverse Effects and Underdosing in a Pregnant Patient A code from subcategory O9A.2 should be

sequenced first, followed by the appropriate injury, poisoning, toxic effect, adverse effect or underdosing code

An additional code(s) is also assigned that specifies the condition caused by the poisoning, toxic effect, adverse effect or underdosing

166

Normal Delivery, Code O80 Code O80 is used for a full-term normal delivery

of a single, healthy infant without any complications antepartum, during the delivery, or postpartum during the delivery episode• Equivalent to 650 in ICD-9-CM

Use code O80 when the patient had an antepartum complication but the complication is not present at the time of admission for delivery

Z37.0, single live birth, is the only outcome of delivery code appropriate for use with O80

The Peripartum and Postpartum Periods Postpartum period begins immediately after

delivery and continues for six weeks following delivery• A postpartum complication is any complication

occurring within the six-week period. Peripartum period is defined as the last month of

pregnancy to five months postpartum. Chapter 15 codes may also be used to describe

pregnancy-related complications after the peripartum or postpartum period if the provider documents that a condition is pregnancy related.

Subsequent encounters for retained products of conception following a spontaneous abortion or elective termination of pregnancy are assigned the appropriate code from category O03, Spontaneous abortion or O07.4, Failed attempted termination of pregnancy and Z33.2. Encounter for elective termination of pregnancy• This advise is appropriate even when the patient was

discharged previously with a diagnosis of complete abortion

171

Page 172: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Complications Leading to Abortion Codes from Chapter 15 may be used as additional

codes to identify any documented complications of the pregnancy in conjunction with codes in categories in O07 and O08

Abuse in a Pregnant Patient For suspected or confirmed cases of abuse of a

pregnant patient, a code(s) from subcategories O9A.3, O9A.4, and O9A.5should be sequenced first, followed by the appropriate codes (if applicable) to identify any associated current injury due to physical abuse, sexual abuse, and the perpetrator of abuse

172

Coding Examples 39 week twin gestation delivery complicated by

nuchal cord without compression of fetus 2. Both infants were liveborn and healthy• O30.003 Twin pregnancy, unspecified # of placenta

and unspecified # of amniotic sacs, third trimester• O69.81X2 Labor and delivery complicated by cord

around neck, without compression, fetus 2• Z3A.39 39 weeks gestation of pregnancy• Z37.2 Twins, both liveborn

173

Coding Examples 3 weeks postpartum seen for nonpurulent

postpartum mastitis• O91.22 Nonpurulent mastitis associated with

puerperium (postpartum) 36 year old G2 P1 at 26 weeks seen for

gestational hypertension• O13.2 Gestational hypertension without significant

proteinuria, second trimester• O09.522 Supervision of elderly multigravida, second

trimester• Z3A.26 26 weeks gestation of pregnancy

174

Page 175: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Principal Diagnosis for Birth Record Assign a code from category Z38 as the principal

diagnosis on the newborn record at the time of birth only

If a newborn is transferred to another institution, a code from category Z38 should not be used at the receiving hospital

Use of Codes from other Chapters with Codes from Chapter 16 Codes from other chapters may be used with codes

from chapter 16 if the codes from the other chapters provide more specific detail. If the reason for the encounter is a perinatal condition, the code from chapter 16 should be sequenced first

175

Page 176: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Use of Chapter 16 codes after the Perinatal Period Should a condition originate in the perinatal

period, and continue throughout the life of the patient, the perinatal code should continue to be used regardless of the patient’s age

Birth Process or Community Acquired Conditions If a newborn has a condition that may be either

due to the birth process or community acquired and the documentation does not indicate which it is, the default is due to the birth process

176

Page 177: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Code all Clinically Significant Conditions All clinically significant conditions noted on

routine newborn examination should be coded.• A condition is clinically significant if it requires:

clinical evaluation; or therapeutic treatment; or diagnostic procedures; or extended length of hospital stay; or increased nursing care and/or monitoring; or has implications for future health care needs

177

Page 178: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Observation and Evaluation of Newborns for Suspected Conditions not Found Reserved for future expansion

Coding Additional Perinatal Diagnoses Assign codes for conditions that require treatment

or further investigation, prolong the length of stay or require resource utilization

Assign codes for conditions that have been specified by the provider as having implications for future health care needs• NOTE: This guideline should not be used for adult

patients

178

Page 179: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Prematurity and Fetal Growth Retardation Providers utilize different criteria in determining

prematurity. A code for prematurity should not be assigned unless it is documented

Assignment of codes in categories P05, Disorders of newborn related to slow fetal growth and fetal malnutrition, and P07, Disorders of newborn related to short gestation and low birth weight, not elsewhere classified, should be based on the recorded birth weight and estimated gestational age• Codes form category P05 should not be assigned with

codes from category P07 When both birth weight and gestational age are

available, two codes from category P07 should be assigned, with the code for birth weight sequenced before the code for gestational age

179

Page 180: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Low Birth Weight and Immaturity Status Codes from category P07, Disorders of newborn

related to short gestation and low birth weight, not elsewhere classified, are for use for a child or adult who was premature or had a low birth weight as a newborn and this is affecting the patient’s current health status.

Stillbirth Code P95, Stillbirth, is only for use in institutions

that maintain separate records for stillbirths. No other code should be used with P95. Code P95 should not be used on the mother’s record.

180

Page 181: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Bacterial Sepsis of Newborn Category P36, Bacterial sepsis of newborn,

includes congenital sepsis If documentation does not specify whether the

sepsis is congenital or community acquired, the default is congenital and a code from category P36 should be assigned

If applicable, use additional codes to identify severe sepsis (R65.2-) and any associated acute organ dysfunction

181

Page 182: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coding Examples 20 day old infant admitted with staphylococcus

aureus sepsis• P36.2 Sepsis of newborn due to staphylococcus

aureus Female infant born in the hospital by vaginal

delivery with fetal alcohol syndrome• Z38.00 Single liveborn infant, delivered vaginally• Q86.0 Fetal alcohol syndrome (dysmorphic)

Male infant born in the hospital by C-section with hyperbilirubinemia• Z38.01 Single liveborn infant, delivered by cesarean• P59.9 Neonatal jaundice, unspecified

182

Page 183: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Assign a code from categories Q00-Q99, Congenital malformations, deformations, and chromosomal abnormalities when documentation supports one of these conditions. These codes may be the principal/first-listed diagnosis or secondary diagnosis

When the documented condition does not have a unique code, assign additional code(s) for any manifestations that may be present

When the code assignment specifically identifies the condition documented, manifestations that are an inherent component of the anomaly should not be coded separately

183

Page 184: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Use of Symptom Codes Codes that describe symptoms and signs are

acceptable for reporting purposes when a related definitive diagnosis has not been established (confirmed) by the provider

Use of a Symptom Code with a Definitive Diagnosis Code Codes for signs and symptoms may be reported in

addition to a related definitive diagnosis when the sign or symptom is not routinely associated with that diagnosis

Signs or symptoms that are associated routinely with a disease process should not be assigned as additional codes, unless otherwise instructed by the classification

184

Page 185: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Combination Codes that Include Symptoms ICD-10-CM contains a number of combination codes

that identify both the definitive diagnosis and common symptoms of that diagnosis. When using one of these combination codes, an additional code should not be assigned for the symptom

Repeated Falls Code R29.6, Repeated falls, is for use for

encounters when a patient has recently fallen and the reason for the fall is being investigated

Code Z91.81, History of falling, is for use when a patient has fallen in the past and is at risk for future falls

185

Page 186: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coma Scale The coma scale codes (R40.2-) can be used in

conjunction with traumatic brain injury codes, acute cerebrovascular disease or sequelae of cerebrovascular disease codes. These codes are primarily for use by trauma registries, but they may be used in any setting where this information is collected

The coma scale codes should be sequenced after the diagnosis code(s)

When the individual scores are documented, three codes, one from each subcategory, are needed to complete the scale. The 7th character indicates when the scale was recorded and should match for all three codes• R40.21-, Coma scale, eyes open• R40.22-, Coma scale, best verbal response• R40.23-, Coma scale, best motor response

186

Page 187: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coma Scale Assign code R40.24, Glasgow coma scale, total

score, when only the total score is documented in the medical record and not the individual score(s)

At a minimum, report the initial score documented on presentation at your facility. This may be a score from the emergency medicine technician or in the emergency department

If desired, a facility may choose to capture multiple coma scale scores

187

Page 188: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Functional Quadriplegia Functional quadriplegia (R53.2) is the lack of ability to use one’s

limbs or to ambulate due to extreme debility. R53.2 should not be used for neurologic quadriplegia. Functional quadriplegia should only be assigned if functional

quadriplegia is specifically documented in the medical record. SIRS due to Non-Infectious Process

When SIRS is documented with a non-infectious condition such as trauma, malignant neoplasm or pancreatitis, the code for the non-infectious condition should be assigned followed by code R65.10 or R65.11

Death NOS Code R99, ill-defined and unknown cause of mortality, is only for

use in the very limited circumstance when a patient who has already died is brought into an emergency department or other healthcare facility

188

Page 189: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coding Examples Bradycardia, sinoatrial• R00.1 Bradycardia, unspecified

Left lower quadrant abdominal tenderness• R10.814 Left lower quadrant abdominal tenderness

Initial Glasgow coma scale recorded by EMT; eyes do not open, no verbal response, with no motor response.• R40.2111 Coma, eyes open, never• R40.2211 Coma, best verbal response, none• R40.2311 Coma, best motor response, none

189

Page 190: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

In ICD-10-CM injuries are grouped by body part rather than by categories of injury, so that all injuries of the specific site (such as head and neck) are grouped together rather than groupings of all fractures or all open wounds

Fracture codes include much greater specificity such as type of fracture, anatomical site, displaced or not, laterality, routine versus delayed healing, and type of encounter

190

Page 191: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Application of 7th Characters Most categories in chapter 19 have a 7th character

requirement for each applicable code. Most categories have three 7th character values with the

exception of traumatic fractures which include several more options

Here is an example • The appropriate 7th character is to be added to all codes

from category S42 A - initial encounter for closed fracture B - initial encounter for open fracture D - subsequent encounter for fracture with routine healing G - subsequent encounter for fracture with delayed healing K - subsequent encounter for fracture with nonunion P - subsequent encounter for fracture with malunion S - sequela

191

Page 192: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coding Injuries When coding injuries, assign separate codes for

each injury unless a combination code is provided, in which case the combination code is used

Code T07, unspecified multiple injuries should not be assigned in the inpatient setting unless information for a more specific code is not available

The code for the most serious injury as determined by the provider and the focus of treatment is sequenced first

192

Page 193: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coding of Traumatic Fractures Multiple fracture coding/sequencing• The principles of multiple coding of injuries should be

followed in coding fractures• Fractures of specified sites are coded individually by site in

accordance with both the Tabular List provisions and the level of detail furnished by medical record content

• Multiple fractures are sequenced according to the severity of the fracture

Default coding• A fracture not indicated as open or closed should be coded

to closed• A fracture not indicated whether displaced or not displaced

should be coded to displaced

193

Page 194: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Initial versus Subsequent Encounter for Fractures Traumatic fractures are coded using an appropriate

7th character for initial encounter (A, B, C) while the patient is receiving active treatment for the fracture

The appropriate 7th character for initial encounter should also be used for a patient who delayed seeking treatment for the fracture or nonunion• Examples of active treatment are:

surgical treatment emergency room encounter evaluation and treatment by a new physician

194

Page 195: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Initial versus Subsequent Encounter for Fractures Fractures are coded using the appropriate 7th

character for subsequent care for encounters after the patient has completed active treatment of the fracture and is receiving routine care for the fracture during the healing or recovery phase• Examples of subsequent care are:

cast change or removal removal of external or internal fixation device medication adjustment follow-up visits following fracture treatment

195

Page 196: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Initial versus Subsequent Encounter for Fractures Complications of fracture• Care of complications of surgical treatment for fracture

repairs during the healing or recovery phase should be coded with the appropriate complication codes

• Care of complications such as malunion and nonunion, should be reported with the appropriate 7th character for subsequent care with nonunion or subsequent care with malunion

The aftercare Z codes should not be used for aftercare for traumatic fractures. For aftercare of a traumatic fracture, assign the acute fracture code with the appropriate 7th character

See Section I.C.13. Osteoporosis for traumatic fractures in a patient with known osteoporosis

196

Page 197: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coding of Burns and Corrosions ICD-10-CM makes a distinction between burns and

corrosions• Burn codes are used for:

Thermal burns, except sunburns that come from a heat source such as fire or hot appliance.

Burns caused by electricity and radiation• Corrosions are burns due to chemicals• The coding guidelines are the same for both burns and

corrosions• All types of burns are classified by depth

first degree – erythema second degree - blistering third degree – full thickness involvement

197

Page 198: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sequencing of burn and related condition codes Sequence first the code that reflects the highest

degree of burn when more than one burn is present.

When there are both internal and external burns, the circumstances of admission govern the selection of the principal or first-listed diagnosis.

When a patient is admitted for both burn injuries and other related conditions such as smoke inhalation and/or respiratory failure, the circumstances of admission govern the selection of the principal or first-listed diagnosis

198

Page 199: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Burns of the same local site Classify burns of the same local site (three-

character category level) but of different degrees to the subcategory identifying the highest degree recorded in the diagnosis

Non-healing burns Non-healing burns are coded as acute burns. Necrosis of burned skin should be coded as a non-

healed burn. Infected burn

For any documented infected burn site, use an additional code for the infection

199

Page 200: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Assign separate codes for each burn site When coding burns, assign separate codes for

each burn site. Category T30, Burns and corrosion, body region unspecified is extremely vague and should rarely be used

Burns and corrosions classified according to extent of body surface involved The extent of body surface involved in burns now

has two separate codes:• T31, Burns classified according to extent of body

surface involved• T32, Corrosions classified according to extent of body

surface involved

200

Page 201: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Encounters for treatment of sequela of burns Encounters for the treatment of the late effects of

burns or corrosions (scars or joint contractures) should be coded with a burn or corrosion code with the 7th character of “S” for sequela

When appropriate, both a code for a current burn or corrosion with 7th character “A” or “D” and a burn or corrosion code with 7th character of “S” may be assigned on the same record when both a current burn and sequela of an old burn exists• Burns and corrosions do not heal at the same rate

and a current healing wound may still exist with sequela of a healed burn or corrosion

201

Page 202: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Adverse Effects, Poisoning, Underdosing and Toxic Effects Codes in categories T36-T65 are combination

codes that include the substance that was taken as well as the intent

No additional external cause code is required for adverse effects, poisoning, underdosing and toxic effect codes

When no intent is indicated, code to accidental. Undetermined intent is only for use when there is

specific documentation in the record that the intent of a toxic effect cannot be determined

202

Page 203: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Adverse Effect When coding an adverse effect of a drug that has

been correctly prescribed and properly administered, assign the appropriate code for the nature of the adverse effect followed by the appropriate code for the adverse effect of the drug• Examples of the nature of an adverse effect are:

Tachycardia, delirium, gastrointestinal hemorrhaging, vomiting, hypokalemia, etc.

The code for the drug should have a 5th or 6th character “5” (adverse effect)

203

Page 204: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Poisoning When coding a poisoning or reaction to the

improper use of medication first assign the appropriate code from categories T36-T50• Poisonings can be an overdose, wrong substance

given or taken in error, wrong route of administration The poisoning codes have an associated intent as

their 5th or 6th character of 1, 2, 3 or 4.• Accidental, intentional self-harm, assault and

undetermined Use additional code(s) for all manifestations of

poisonings

204

Page 205: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Underdosing Underdosing refers to taking less of a medication than

is prescribed by a provider or a manufacturer’s instruction.

For underdosing assign the code from categories T36-T50 with a 5th or 6th character of “6” (underdosing)

Codes for underdosing should never be assigned as principal or first-listed diagnosis• If a patient has a relapse or exacerbation of the medical

condition for which the drug is prescribed because of underdosing, then the medical condition itself should be sequenced as the principal or first-listed diagnosis

Noncompliance (Z91.12-, Z91.13-) or complication of care (Y63.6-Y63.9) codes are to be used with an underdosing code to indicate intent, if known

205

Page 206: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Toxic Effects When a harmful substance is ingested or comes in

contact with a person, this is classified as a toxic effect

Toxic effect codes are in categories T51-T65. Toxic effect codes have an associated intent:• accidental• intentional self-harm• assault• undetermined

Undetermined is based on documentation that the intent cannot be determined.

206

Page 207: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Adult and child abuse, neglect and other maltreatment Two code categories are used to report abuse,

neglect and other maltreatment• T74- Adult and child abuse, neglect and other

maltreatment, confirmed• T76- Adult and child abuse, neglect and other

maltreatment, suspected If abuse or neglect is documented in the medical

record code as confirmed (T74.-) If the documentation indicates suspected abuse

or neglect code as suspected (T76.-)

207

Page 208: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Adult and child abuse, neglect and other maltreatment Ruled out abuse or neglect is coded • Z04.71, Encounter for examination and observation

following alleged physical adult abuse, ruled out • Z04.72, Encounter for examination and observation

following child alleged physical abuse, ruled out• Z04.41, Encounter for examination and observation

following alleged adult rape, ruled out• Z04.42, Encounter for examination and observation

following alleged child rape, ruled out

208

Page 209: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Pain due to medical device Pain associated with devices, implants or grafts

left in a surgical site is assigned to the appropriate code(s) found in Chapter 19

Specific codes for pain due to medical devices are found in the T code section of ICD-10-CM

Use additional code(s) from category G89 to identify acute or chronic pain due to presence of the device, implant or graft (G89.18 or G89.28)

209

Page 210: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Transplant complications Transplant complications other than kidney• Codes under category T86, Complications of

transplanted organs and tissues, are used for both complications and rejection of transplanted organs.

• Assign a transplant complication code only if the complication affects the function of the transplanted organ.

• Two codes are required to fully describe a transplant complication: the appropriate code from category T86 and a secondary code that identifies the complication

210

Page 211: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Kidney transplant complications Patients who have undergone kidney transplant

may still have some form of chronic kidney disease (CKD)

T86.1- is used for documented complications of a kidney transplant, such as transplant failure or rejection or other transplant complication

Do not assign T86.1- for post kidney transplant patients with CKD and no other documented transplant complication

T86.1- requires an additional code that identifies the complication

211

Page 212: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Complication codes that include the external cause Some of the complications of care codes have the

external cause included in the T code The code includes the nature of the complication

as well as the type of procedure that caused the complication

No external cause code indicating the type of procedure is necessary for these codes

212

Page 213: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Complications of care codes within the body system chapters Intraoperative and postprocedural complication

codes are found within the body system chapters • The codes are specific to the organs and structures

of that body system These codes should be sequenced first, followed

by a code(s) for the specific complication, if applicable.• Example: Accidental laceration digestive system,

during procedure on digestive system – K91.71

213

Page 214: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coding Examples Current 2 cm laceration of the left heel with

foreign body• S91.322 Laceration with foreign body, left foot

Displaced, compound comminuted fracture of the right radial shaft. Type II open fracture• S52.351B Displaced comminuted fracture of shaft of

radius, right arm, initial encounter open fracture type I or II

Nonunion of a left trimalleolar fracture• S82.852K Displaced trimalleolar fracture, left lower

leg, subsequent encounter for fracture with nonunion

214

Page 215: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Coding Examples Nausea and vomiting secondary to digoxin taken

appropriately• R11.2 Nausea with vomiting, unspecified• T46.0X5A Adverse effect of cardiac-stimulant glycosides

and drugs of similar action, initial encounter Nausea and vomiting in a 2 year old due to accidental

overdose of acetaminophen.• T39.1X1A Poisoning by 4-Aminophenol derivatives,

accidental (unintentional), initial encounter • R11.2 Nausea with vomiting, unspecified

Infected right hip prosthesis• T84.51XA Infection and inflammatory reaction due to

internal right hip prosthesis, initial encounter

215

Page 216: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Categories V, W, X, Y are the equivalent of the E code categories in ICD-9-CM

External cause codes are intended to provide data for injury research and evaluation of injury prevention strategies

These codes capture: how the injury or health condition happened (cause), the intent (unintentional or accidental); or intentional,

such as suicide or assault the place where the event occurred the activity of the patient at the time of the event the person’s status (civilian, military)

216

Page 217: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

External cause code used for length of treatment Assign the external cause code, with the

appropriate 7th character (initial encounter, subsequent encounter or sequela) for each encounter for which the injury or condition is being treated

Use the full range of external cause codes Use the full range of external cause codes to

completely describe the cause, the intent, and the place of occurrence

If applicable, the activity of the patient at the time of the event, and the patient’s status

217

Page 218: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Combination External Cause Codes Some external cause codes are combination codes

that identify sequential events that result in an injury, such as a fall which results in striking against an object. The injury may be due to either event or both

The combination external cause code used should correspond to the sequence of events regardless of which caused the most serious injury

No External Cause Code Needed in Certain Circumstances No external cause code from Chapter 20 is needed if

the external cause and intent are included in a code from another chapter

218

Page 219: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Place of Occurrence and Activity Codes Place of occurrence and activity codes are used

only once at the initial encounter for treatment Place of occurrence and activity codes should be

used in conjunction with each other• If you have a Y92 code you should also have a Y93

code External Cause Status

Y99 codes should be assigned whenever any other external cause code is assigned for an encounter

Y99 codes indicate whether the event was military, or the individual was a civilian, student or volunteer

219

Page 220: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Multiple External Cause Coding Guidelines If two or more events cause separate injuries, an

external cause code should be assigned for each cause• The first listed external cause code will be selected as

follows: External cause codes for child and adult abuse take priority

over all other external cause codes External cause codes for terrorism events take priority over

all other external cause codes except child and adult abuse External cause codes for cataclysmic events take priority

over all other external cause codes except child and adult abuse and terrorism

External cause codes for transport accidents take priority over all other external cause codes except cataclysmic events, child and adult abuse and terrorism

Activity and external cause status codes are assigned following all causal (intent) external cause codes

220

Page 221: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Child and Adult Abuse Guideline Adult and child abuse, neglect and maltreatment are

classified as assault Any of the assault codes may be used to indicate the

external cause of any injury resulting from the confirmed abuse

For confirmed cases of abuse, neglect and maltreatment, when the perpetrator is known, a code form Y07, should accompany any other assault codes

Unknown or Undetermined Intent Guideline If the intent of the cause of an injury or other condition is

unknown or unspecified, code the intent as accidental intent

Undetermined intent is only used if documentation in the record specifies that the intent cannot be determined

221

Page 222: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Sequelae of External Cause Codes Sequela are reported using the external cause

code with the 7th character “S” for sequela • Use these codes with any report of a sequela

resulting from a previous injury A sequela external cause code should never be

used with a related current nature of injury code Use a sequela external cause code for subsequent

visits when a late effect/sequela of the initial injury is being treated• Do not use a late effect/sequela external cause code

for subsequent visits for follow-up care of the injury when no late effect of the injury has been documented

222

Page 223: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Terrorism Guidelines When the cause of injury is identified by the FBI

as terrorism, the first-listed external cause code should be a code from category Y38, Terrorism

Suspected cases of terrorism should be classified as assault

Y38.9, Terrorism, secondary effects. is used when conditions occur subsequent to the terrorist event.

223

Page 224: Presenter: Kathy Boomgarden, RHIT, CCS, CCS-P AHIMA-Approved ICD-10-CM/PCS Trainer

Z codes are equivalent to V codes in ICD-9-CM

Z codes indicate a reason for an encounterThe Z code categories are the same as they

were for ICD-9-CM Contact/Exposure, Inoculations and Vaccinations,

Status, History (of), Screening, Observation, Aftercare, Follow-up, Donor, Counseling, Obstetrical and reproductive services, Newborns and infants, Routine and administrative examinations, Prophylactic organ removal, Miscellaneous Z codes, and Nonspecific Z codes
