What 80324 covers

80324 represents definitive laboratory drug testing for one or two substances in the amphetamine class. A clinician orders the analysis when specific drug identification is needed, and a clinical laboratory performs or reports the testing. The code is selected by the number of amphetamine-class substances analyzed; it is not a broad panel code for unrelated drug classes. The count distinguishes 80324 from the higher-count amphetamine codes.

Medicare marks 80324 not valid for Medicare (status I) and uses a different code to report and pay for the service. 80324 is a CPT Category I code, but it is not the Medicare reporting code for this service. Codes 80306 and 80307 describe presumptive drug testing, whereas 80324 represents definitive testing. The one-or-two distinction selects the code based on substances tested, not specimens submitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

80324 billing questions

When is 80324 selected instead of 80325 or 80326?

Select 80324 for one or two substances in the amphetamine class. Codes 80325 and 80326 cover higher substance counts in that class.

Is 80324 a presumptive drug test?

No. 80324 represents definitive testing; 80306 and 80307 describe presumptive testing methods.

How does the one-or-two distinction affect code selection?

It refers to the number of amphetamine-class substances tested, not the number of specimens.

Can Medicare claims report 80324?

No. Medicare status I identifies 80324 as not valid for Medicare; Medicare uses a different code to report and pay for the service.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
