> Medicare paid $289.61 for CPT 77280 in the office (non-facility) setting and $289.61 in a facility under the Q1 2021 Physician Fee Schedule, effective January 2021. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This is a 2.2% increase from the previous quarter.

## What it is

A rehearsal session that sets up the geometry of radiation treatment before any therapeutic dose is given. The patient is positioned exactly as they will be for treatment, imaging confirms where the beam will land, and reference marks are placed on the skin or on an immobilization device so the setup can be reproduced every day. Simple is the most basic level, used for a single treatment area handled with one or two beam directions, without elaborate shaping.
