What 0577T is

Medicare payment for 0577T (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 0577T at 1 unit per date of service for practitioner claims (MAI 2 - date of service edit (absolute): units above the MUE never pay), rationale: Code Descriptor / CPT Instruction. Units above the cap are denied unless the edit's adjudication rules allow an appeal with documentation.
