What 77372 covers
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.
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.

How to choose
- 77371SRS deliveryMultisource cobalt-60
- Choose 77372 for linear accelerator-based cranial radiosurgery; 77371 describes multisource delivery for cranial radiosurgery.
- 77373SBRT deliveryPer fraction, up to five
- 77372 is single-session cranial radiosurgery. 77373 describes stereotactic body radiation treatment delivery, generally used for extracranial targets and a course delivered in fractions.
- 77301IMRT planningDose optimization and volume analysis
- 77301 reports IMRT dose planning, not linear accelerator cranial radiosurgery delivery. A planning service is not a substitute for the delivered treatment code.
77372 billing questions
How does 77372 differ from 77371?
Both represent single-session cranial stereotactic radiosurgery, but 77372 is for linear accelerator-based delivery; 77371 is for multisource delivery.
Can 77372 be reported for each treated lesion?
No. It represents the complete single-session course, rather than a separate unit for each cranial target.
Is the physician service included in 77372?
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.
Does 77372 describe treatment planning?
No. It describes delivery. A dose-planning service such as 77301 is distinct from the treatment session.
What documentation supports reporting 77372?
Document the cranial target or targets, the linear accelerator used, and completion of the single-session treatment delivery.
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.
