Frequently asked questions
Is HCPCS code G1021 still valid?
No. CMS terminated G1021; its last date of service was Dec 31, 2024. It is listed for looking up services from before then. Use a current code for newer services.
Does Medicare cover G1021?
CMS lists G1021’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.
Which HCPCS Level II release does this page use?
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.
