What 77435 covers
77435 represents the radiation oncologist’s management of a stereotactic body radiation therapy course, rather than delivery of each radiation fraction. The physician oversees treatment for one or more targeted lesions, reviews the patient’s progress and treatment information, and addresses clinical issues during the course. SBRT is commonly used for carefully targeted tumors, including lesions in the lung, liver, or spine. Radiation oncologists typically provide this service in hospital outpatient departments and freestanding radiation oncology centers.
Report 77435 once for the treatment course, not once per lesion or fraction. Documentation should identify the SBRT course and lesions treated and support the physician’s management of the patient during treatment. CMS classifies 77435 as professional-component-only: it represents the physician’s interpretation and report, while a separate code covers the technical service. The SBRT delivery service is reported separately with 77373 when appropriate; 77435 is not the fraction-by-fraction delivery 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.

77435 billing questions
Is 77435 reported per fraction or per treatment course?
Report it for the SBRT treatment course, not for each delivery fraction. The number of lesions treated does not create additional units of 77435.
How does 77435 differ from 77373?
77435 represents the radiation oncologist’s professional management of the course. 77373 reports SBRT treatment delivery by fraction.
Should modifier 26 be appended to 77435?
No. CMS identifies 77435 as professional-component-only, so modifier 26 is not needed to designate its professional service. The technical service is reported separately.
Can 77435 be reported for a single-session cranial stereotactic treatment?
Compare the clinical service with 77432, which describes management of a complete one-session stereotactic treatment for cranial lesions. 77435 is for SBRT course management.
When would 77427 be considered instead?
77427 describes radiation treatment management in a five-treatment unit for conventional radiation therapy. Use 77435 for management of an SBRT course, not routine management counted in five-treatment units.
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.
