What 77261 covers

A radiation oncologist uses this service to develop a simple external-beam radiation treatment approach after reviewing relevant clinical information, such as the cancer diagnosis, disease extent, imaging, and prior treatment. Planning may include defining the treatment approach and determining the intended dose and beam arrangement. It is performed in radiation oncology practices and hospital-based cancer centers as part of preparing a patient’s course of treatment.

Select the simple level based on the documented complexity of the physician’s planning work; do not infer the level from a field count alone. The record should support the clinical information reviewed and the treatment decisions made. CMS identifies 77261 as a professional-component-only service: it represents the physician’s interpretation and report, while a separate code accounts for the technical portion. Field simulation and dosimetry calculations are distinct services when performed and documented; this planning code does not itself describe those services.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

77261 billing questions

How does 77261 differ from 77262?

77261 is for simple treatment planning, while 77262 is for intermediate planning. Choose the level supported by the physician’s documented planning complexity rather than relying on a field count alone.

Is treatment simulation included in 77261?

No. Simulation, such as setting up treatment geometry, is a distinct service. Code 77280 describes simple radiation field simulation when that service is performed and documented.

Does 77261 include the technical portion of planning?

No. CMS identifies 77261 as professional-component-only for the physician’s interpretation and report; a separate code covers the technical portion.

What documentation supports the simple planning level?

Document the clinical information reviewed and the physician’s treatment-planning decisions. The record should support why the planning work meets the simple level.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
