What 77373 covers
Stereotactic body radiation therapy (SBRT) delivers precisely targeted, high-dose radiation to tumors outside the brain, commonly in the lung, liver, or spine. Radiation oncologists prescribe and oversee treatment, while radiation therapists deliver each fraction using specialized equipment and image guidance to position and verify the target. The service is performed in a radiation oncology treatment setting.
Report 77373 once for each treatment fraction, whether one or multiple lesions are treated in that fraction; the code describes a course of no more than five fractions. The treatment record should support the treated target or targets, fraction date, image-guided setup, and completed delivery. Image guidance is included in the service. CMS treats this as a technical-component-only code; a separate code covers interpretation. The CMS fee schedule assigns no physician-work value to this code.
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.

77373 billing questions
Is 77373 reported per lesion or per fraction?
Report it per fraction, not once for each lesion. The code covers treatment of one or more lesions in that fraction.
What documentation supports a 77373 claim?
The treatment record should identify the target or targets, the date and fraction delivered, image-guided setup, and completion of treatment delivery.
Can image guidance be billed separately with 77373?
Image guidance is included in 77373, so it should not be separately reported for the same SBRT delivery.
Does 77373 include the physician's interpretation?
No. CMS classifies 77373 as technical-component-only; a separate code covers interpretation.
How does 77373 differ from 77371 and 77372?
77373 is for stereotactic radiation treatment of body targets. Codes 77371 and 77372 describe stereotactic radiosurgery delivery for intracranial targets.
Is 77373 the same service as SBRT treatment management?
No. 77373 reports treatment delivery by fraction; 77435 reports physician treatment management for the SBRT course.
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.
