Seminar 8

Lab tests Laboratory codes describe the

performance of lab tests A specimen includes:

Tissue (e.g. blood and urine) The CPT lab tests do not include collection of the specimen used to perform the test

Venipuncture or phlebotomy is the puncture of a vein using a needle for the purpose of drawing blood

Most common method of collecting blood specimens

Certain lab tests contain both a professional and technical component—make sure to read the code description completely

More than one procedure It is appropriate to separately code and

report multiple pathology and laboratory procedures that are provided on the same date of service

It is NOT appropriate to report tests that are repeated simply to confirm initial results, or when a series of tests is performed—these services are considered part of the originally ordered test and are not separately reported

Modifiers: Do not use modifier 51 for multiple

procedures Use modifier 91 for repeated clinical

diagnostic lab tests
