What 77402 covers

This code represents the technical delivery of a simple external-beam radiation treatment session. Radiation therapists typically operate the treatment equipment in a radiation oncology department, following the radiation oncologist’s prescription and treatment plan. The level reflects delivery complexity; the diagnosis or body site alone does not determine the level. The session record should show the treatment delivered and the technical details supporting level 1 rather than a higher-complexity delivery code.

Report the code for the qualifying delivery session, not separately for each beam or port. Documentation should support the delivered treatment and its level. CMS classifies 77402 as technical-component-only: a separate code covers interpretation, so this code does not represent the physician’s interpretive service. CMS assigns no physician work RVU to the delivery code; its payment valuation reflects practice expense and malpractice components.

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.

77402 billing questions

How is level 1 distinguished from levels 2 and 3?

Choose the level that matches the technical complexity of the delivered treatment, not the diagnosis or treatment site alone. The treatment record should support why the session meets level 1 rather than a higher level.

Is 77402 reported for each beam or port?

No. It represents the qualifying delivery session; do not count each beam or port as a separate unit.

Does 77402 include the physician’s interpretation?

No. CMS classifies it as a technical-component-only code, and a separate code covers interpretation.

What documentation supports reporting 77402?

The treatment record should identify the delivered session and include technical details that support level 1. The record should also allow the reported delivery level to be distinguished from levels 2 and 3.

Is 77417 the same service as 77402?

No. 77402 reports radiation treatment delivery; 77417 represents therapeutic radiology port imaging when that imaging service is performed.

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.
