Medicare payment for 0408T (CY2026)

This code has no Physician Fee Schedule rate: Carrier-priced - the Medicare contractor sets the price. It may be paid under a different fee schedule (clinical laboratory, DMEPOS, anesthesia) or not paid at all - check the relevant CMS schedule.

Medically Unlikely Edit (MUE)

Medicare caps 0408T at 1 unit per date of service for practitioner claims (MAI 3 - date of service edit (clinical): units above the MUE may pay with documentation on appeal), rationale: Nature of Service/Procedure. Units above the cap are denied unless the edit's adjudication rules allow an appeal with documentation.
