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
