G0666 HCPCS Level II code: Team remote e/m est. pt 15mins

G0666 is the HCPCS code for “Team remote e/m est. pt 15mins” in CMS’s HCPCS Level II October 2026 release.

CMS lists G0666’s Medicare coverage as “Carrier judgment” and its pricing as “Service not separately priced by Part B (e.g., services not covered, bundled, used by Part A only, etc.)”. Coverage and payment still depend on the patient, the setting, the documentation and the payer.

It uses CMS’s October 2026 release, in effect from Oct 1, 2026 to Dec 31, 2026. It is a reference: confirm the code against the current list and the payer’s rules before you submit it.
