2026 HCPCS Update: Key Changes to Oncology Radiation Treatment Procedure Codes
Starting January 01, 2026, the Centers for Medicare & Medicaid Services updated radiation treatment procedure codes as part of the 2026 annual HCPCS update.
As part of the annual update, CMS discontinued previously active procedure codes 77014, 77385, and 77386 and the following G codes for claims for image-guidance services in offices and clinics:
| G Codes | ||||||
| G6001 | G6002 | G6003 | G6004 | G6005 | G6006 | G6007 |
| G6008 | G6009 | G6010 | G6011 | G6012 | G6013 | G6014 |
| G6015 | G6016 | G6017 | ||||
CMS did not assign direct replacement codes for the discontinued codes.
The usual review period for payers and state Medicaid programs was shorter than normal because of the federal government shutdown. CMS could not release the annual HCPCS file on its usual schedule. Because of that delay, many programs did not have enough time to fully review the effect on claims and reimbursement before the changes started.
The Texas Health and Human Services Commission said it is aware of the problem and the effect it may have on providers and members receiving care. HHSC is working on a fix and has submitted a Medicaid State Plan Amendment to CMS. HHSC requested an effective date of January 01, 2026.
HHSC will also hold a rate hearing on April 24, 2026. The hearing will cover proposed changes meant to address the effect of the discontinued codes. Providers can find meeting notices on the Texas Health and Human Services Meetings & Events page. Rate hearing packets are also available on the Provider Finance Department page.
At this time, CMS allows reimbursement for the affected services in office and clinic settings under these procedure codes:
77402, 77407, and 77412
HHSC is asking affected providers to file claims on time using the code that best matches the service provided. For now, that means using 77402, 77407, or 77412 while system updates are still in progress.
Because the HCPCS update took effect on January 1, 2026, the first 95-day filing deadline for these claims is Monday, April 06, 2026.
Providers should still submit timely claims, but they should also know that claims may continue to be denied in some cases. This may affect billing providers that use 77402, 77406, or 77412 in office or clinic settings until CMS approvals are complete and HHSC finishes the rate hearing process.
HHSC said it will share more guidance on claims submission and any added steps that providers or MCOs may need to take.
