The 2026 radiation oncology codes are now in effect

The 2026 radiation oncology code changes took effect on January 1. Claims for 2026 dates of service must use the new delivery codes 77402, 77407 and 77412, and report image guidance as 77387 with modifier 26. The deleted codes are rejected for 2026 dates.

The Iridium Suite claim scrubber was updated for the new codes before the change. For what the fee schedule means for payment, read the 2026 Medicare fee schedule for radiation oncology.
