Medicare payment for G0118 (CY2026)

National rates: total RVUs x the CY2026 conversion factor of 33.4009 (non-QP), before geographic adjustment. Actual Medicare payment is 80% of the rate shown after the deductible; the patient or secondary payer owes the 20% coinsurance.

Status: Injections - payable only when no other payable service is billed the same day. Global period: Global concept does not apply.

Medically Unlikely Edit (MUE)

Medicare caps G0118 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.
