AMA CPT® Assistant - 2000 Issue 3 (March)
Reporting Drug Testing Codes (March 2000)
March 2000 pages 1-3 Reporting Drug Testing Codes The CPT codes used to report drug testing are located in three subsections of the pathology and laboratory section of the CPT book: Drug Testing (80100-80103), Therapeutic Drug Assays (80150 - 80299), and Chemistry (82000-84999). Qualitative assays (tests that detect whether a particular analyte, constituent, or condition is present) are reported with the drug testing codes; quantitative assays (tests that give results expressing the specific numerical amount of an analyte in a specimen) are reported with the therapeutic drug assay or chemistry codes. The qualitative assay codes are as follows: 80100Drug...
