CMS definition
The principal diagnosis is the diagnosis most related to the current plan of treatment.
It may or may not be related to the patient’s most
DETERMINING PRIMARY DIAGNOSIS: The logic for determining the primary (first listed) diagnosis remains unchanged.
It may or may not be related to the patient s most recent hospital stay, but must relate to the services the home health agency rendered.
If more than one diagnosis is treated concurrently, enter the diagnosis that represents the most acute condition and requires the most intensive services.
Skilled services (SN, PT, OT and SP) only.
The assessing clinician has to determine the primary and secondary diagnoses and symptom control rating, after
completing the OASIS Assessment
DETERMINING PRIMARY DIAGNOSIS:
Why am I seeing this patient?
What is the primary focus of skilled services?
Are there co-morbidities that may impact the POC?
Do not consider the number of visits per discipline as a basis for your decision!
INCLUDE those conditions actively addressed as well as any co-morbidities affecting the patient’s response to treatment
Determining Primary/Secondary Diagnoses:
EXCLUDE diagnoses that no longer pertain to the plan of care, i.e., hip fracture, appendicitis, gangrene, etc.

Co-Morbidity Information:
There are some co-morbidities that should always be coded because they are impacted or they may impact the care.
CMS states that any co-morbidity affecting the patient’s responsiveness to treatment and rehabilitative prognosis, even if the condition is not the focus of any home health treatment itself, should be listed.
Diabetes COPD
HTN CHF
CAD Status amputation
ALWAYS CODE THESE CO-MORBIDITIES
C S a us a pu a o
PVD Blindness
Chronic diseases, such as Parkinson’s
History of malignant neoplasm when care is directed at a current neoplasm or otherwise impacts the care
Co-Morbidity Information
Plan of Care should reflect all diagnoses including co-morbidities#21 SN to assess diabetes and HTN for potential impact on
plan of care
#22 Patient will have no complications related to diabetes#22 Patient will have no complications related to diabetes and HTN this episode
If therapy only, co-morbidities must also be addressed in therapy Plan of CarePT to check blood pressure every visit and report to physician
if >185/95 and/or < 90/60
Patient’s blood pressure will remain within parameters this episode

In the context of these guidelines, the term provider is used throughout the guidelines to mean physician or any qualified health care practitioner who is legally accountable for establishing the patient’s diagnosis.

M1024 facts
M1024 does not automatically go to the UB04 or 485 as it for HHRG calculation only
Diagnosis must be in M1020 or M1022 to appear on 485 or UB04on 485 or UB04
Guidance from CMS – the diagnosis in M1024 must appear on the 485 either in items 11, 13 or 21
So must ASK …
M1024 facts
Does the condition still exist?
If no, then list in M1024 and include on 485 #21 but DO NOT list in M1022
If yes, then no need to list in M1024 per Attachment D guidelines as will be in M1022 as condition still exists
When to complete M1024
Skip M1024 if –
No V code in Column 2 for M1020 or M1022

Diagnoses, Symptom Control, and Payment Diagnoses: List each diagnosis for which the patient is receiving home care
(Column 1) and enter its ICD-9-C M code at the level of highest specificity (no surgical/procedure codes) (Column 2).
Diagnoses are listed in the order that best reflect the seriousness of each condition and support the disciplines and services
provided. Rate the degree of symptom control for each condition (Column 2). Choose one value that represents the
degree of symptom control appropriate for each diagnosis: V-codes (for M1020 or M1022) or E-codes (for M1022 only)
may be used. ICD-9-C M sequencing requirements must be followed if multiple coding is indicated for any diagnoses. If a
V-code is reported in place of a case mix diagnosis, then optional item M1024 Payment Diagnoses (Columns 3 and 4) may
be completed. A case mix diagnosis is a diagnosis that determines the Medicare P P S case mix group. Do not assign
symptom ratings for V- or E- codes.
Code each row according to the following directions for each column:
Column 1: Enter the description of the diagnosis.
Column 2: Enter the ICD-9-C M code for the diagnosis described in Column 1;
Rate the degree of symptom control for the condition listed in Column 1 using the following scale:
0 - Asymptomatic, no treatment needed at this time
1 - Symptoms well controlled with current therapy
2 - Symptoms controlled with difficulty, affecting daily functioning; patient needs ongoing monitoring
3 - Symptoms poorly controlled; patient needs frequent adjustment in treatment and dose monitoring
4 - Symptoms poorly controlled; history of re-hospitalizations
Note that in Column 2 the rating for symptom control of each diagnosis should not be used to determine the sequencing
of the diagnoses listed in Column 1. These are separate items and sequencing may not coincide. Sequencing of
diagnoses should reflect the seriousness of each condition and support the disciplines and services provided.
Column 3: (OPTIONAL) If a V-code is assigned to any row in Column 2, in place of a case mix diagnosis, it may be
necessary to complete optional item M1024 Payment Diagnoses (Columns 3 and 4). See OASIS-C Guidance
Manual.
Column 4: (OPTIONAL) If a V-code in Column 2 is reported in place of a case mix diagnosis that requires multiple diagnosis
codes under ICD-9-C M coding guidelines, enter the diagnosis descriptions and the ICD-9-C M codes in the same
row in Columns 3 and 4. For example, if the case mix diagnosis is a manifestation code, record the description
and ICD-9-C M code for the manifestation in Column 4 of that row. Otherwise, leave Column 4 blank in that row.
