G0446 descriptor and code status
The October 2026 HCPCS Level II file describes G0446 as “Annual, face-to-face intensive behavioral therapy for cardiovascular disease, individual, 15 minutes”. It sits in the G section (procedures and professional services, temporary), listed with the other G codes. Although searches often call it the "G0446 CPT code", G0446 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.
