G0180 descriptor and code status

The October 2026 HCPCS Level II file describes G0180 as “Physician or allowed practitioner certification for medicare-covered home health services under a home health plan of care (patient not present), including contacts with home health agency and review of reports of patient status required by physicians and allowed practitioners to affirm the initial implementation of the plan of care”. It sits in the G section (procedures and professional services, temporary), listed with the other G codes. Although searches often call it the "G0180 CPT code", G0180 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.
