CPT code 80325: Amphetamine testing, 3 or 4 analytes2026 Medicare rate & RVUs in Missouri

CMS doesn’t publish an office rate for 80325 in Missouri.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 80325 covers

CPT 80325 identifies definitive drug testing for the amphetamine class when the assay grouping includes three or four analytes. A laboratory reports this code for testing in that analyte-count range. The distinction among 80324, 80325, and 80326 is the number of amphetamine analytes in the grouping: one or two, three or four, or five or more, respectively. Code 80307 describes presumptive drug testing using a chemistry analyzer, a different testing approach from the definitive amphetamine grouping represented by 80325.

For Medicare, status I means 80325 is not valid for Medicare reporting; Medicare uses a different code to report and pay for this service. The analyte range identifies the appropriate code in the CPT amphetamine series; it is not a count of specimens. Laboratory billing staff should distinguish this analyte grouping from presumptive drug-testing reporting, which has its own code.
