Radiation therapy
Reports technical delivery of a complete, single-session course of linear accelerator stereotactic radiosurgery for one or more cranial lesions.
Code 77372 covers delivery of a complete course of cranial stereotactic radiosurgery in one session using a linear accelerator. The radiation is tightly focused on one or more intracranial targets, such as a brain metastasis, vestibular schwannoma, or arteriovenous malformation. Radiation oncologists direct treatment, with medical physicists and radiation therapists supporting planning and machine delivery in a radiation oncology setting.
Report the code for the completed treatment delivery, not for planning alone or separately for each target, beam, or arc. Documentation should identify the cranial target or targets, the linear accelerator platform, and the delivered session. CMS classifies 77372 as a technical-component-only service; the physician’s separate treatment-management service is reported separately when applicable. Code 77432 describes management of a single-session course of cranial stereotactic radiation and is commonly paired with the technical delivery.

Choose 77372 for linear accelerator-based cranial radiosurgery; 77371 describes multisource delivery for cranial radiosurgery.
77372 is single-session cranial radiosurgery. 77373 describes stereotactic body radiation treatment delivery, generally used for extracranial targets and a course delivered in fractions.
77301 reports IMRT dose planning, not linear accelerator cranial radiosurgery delivery. A planning service is not a substitute for the delivered treatment code.

Both represent single-session cranial stereotactic radiosurgery, but 77372 is for linear accelerator-based delivery; 77371 is for multisource delivery.
No. It represents the complete single-session course, rather than a separate unit for each cranial target.
No. CMS identifies 77372 as technical-component-only. The physician’s treatment-management service is separate; 77432 is the code for management of a single-session cranial course.
No. It describes delivery. A dose-planning service such as 77301 is distinct from the treatment session.
Document the cranial target or targets, the linear accelerator used, and completion of the single-session treatment delivery.
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
