It sits in the G section (procedures and professional services, temporary), listed with the other G codes. Although searches often call it the "G0023 CPT code", G0023 is a HCPCS Level II code maintained by CMS, not an AMA CPT code; both go in the same procedure-code field on the claim.

Medically Unlikely Edits for G0023

MUE limits for G0023: practitioner 1 (MAI 2, Code Descriptor / CPT Instruction); hospital outpatient 1 (MAI 2, Code Descriptor / CPT Instruction). The practitioner MUE is a date-of-service policy edit: units above the limit deny even when split across lines, and appeals rarely succeed.

The MUE lookup for G0023 shows every setting next to any other code on the same claim.

NCCI edits and add-on rules

No active practitioner PTP pair lists G0023 in v323r0.

G0023 is a designated primary code for 1 add-on code (G0024).

Pair counts show exposure, not the answer for one claim. Check G0023 against a second code to see whether the pair bundles and whether a modifier can separate the services.

Medicare coverage policies for G0023

No current LCD or billing and coding article lists G0023. The HCPCS coverage code C means carrier judgment, so the Medicare contractor decides coverage, and any National Coverage Determination for the service still applies.
