December 1999 page 10 Coding Consultation Pathology and Laboratory, 84153, 84154 (Q&A) Question How do you code for fractionated prostate specific antigen tests? AMA Comment Prostate specific antigen (PSA) is a serine protease that exists in the serum both in a free form (fPSA) and complexed with other protein forms. The majority of PSA is complexed with alpha-1-chymotrypsin (cPSA) with an additional immunologically unmeasurable fraction bound to alpha-2-macroglobulin. Over the years, total PSA (tPSA) testing has been useful in screening for prostate carcinoma as well as monitoring men with prostate cancer. However, tPSA testing alone lacks specificity to...

Article Overview
This Q&A article discusses laboratory coding considerations for fractionated prostate-specific antigen testing in the context of pathology and laboratory services. It explains the general reporting framework for prostate-related PSA fractions, the relationship between total and free PSA testing, and the CPT perspective on a directly measured complexed PSA result. The piece is intended for coders, billers, and laboratory professionals who need to understand how the topic was approached in CPT Assistant during this period.
Why This Topic Matters
Laboratory PSA testing can involve multiple related assay components, so understanding the article helps readers identify which coding concepts were being discussed for pathology and laboratory reporting in late 1999. It is useful for historical coding reference and for users researching CPT Assistant guidance on prostate cancer–related laboratory testing.
