`0507U`

What 0507U is

This code appears in the Medicare NCCI edit tables. It has no RVUs in the CY2026 Physician Fee Schedule file.

Medically Unlikely Edit (MUE)

Medicare caps 0507U 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.
