Payer Issues with the 2026 Revised Treatment Delivery Codes
ASTRO is actively monitoring payer implementation of the revised radiation treatment delivery codes (CPT codes 77402, 77407, and 77412) and engaging with them to support appropriate coverage and payment consistent with CMS policy and clinical intent. If a payer denies, downcodes, or underpays one of these codes, start here. We’ll show what’s happening, what ASTRO is doing and what to do next.
