Medically Unlikely Edits for G2088

CMS publishes no MUE for G2088 in the 2026 Q4 practitioner, facility or DME supplier tables. Some MUE values are confidential and applied without publication, so unit limits can still deny; document the quantity furnished on every claim.

The MUE lookup for G2088 shows every setting next to any other code on the same claim.

NCCI edits and add-on rules

No active practitioner PTP pair lists G2088 in v323r0.

G2088 is an add-on code: it is payable only with a primary service on the same claim (G2086, G2087). CPT primary codes are shown as numbers only.

Pair counts show exposure, not the answer for one claim. Check G2088 against a second code to see whether the pair bundles and whether a modifier can separate the services.

Medicare coverage policies for G2088

No current LCD or billing and coding article lists G2088. The HCPCS coverage code C means carrier judgment, so the Medicare contractor decides coverage, and any National Coverage Determination for the service still applies.
