What 77432 covers

77432 represents physician management of a complete stereotactic radiation course delivered in one session to one or more cranial lesions. It is used in stereotactic radiosurgery, commonly for intracranial targets treated by a radiation oncology team. The code describes the physician’s professional work, not the equipment-based delivery of radiation.

Select this code when the cranial stereotactic treatment course is completed in one session; a different management code is used for stereotactic body radiation therapy. Documentation should identify the cranial target or targets, the single-session course, and the physician’s management, interpretation, and report. CMS classifies 77432 as professional-component-only: the physician claim covers interpretation and report, while a separate code covers the technical portion of treatment 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.

77432 billing questions

When should 77432 be used instead of 77435?

Use 77432 for management of a complete, single-session stereotactic course for cranial lesions. 77435 is the management code associated with stereotactic body radiation therapy.

Is the radiation delivery included in 77432?

No. 77432 represents the professional interpretation and report; a separate code covers the technical treatment delivery.

Can 77432 be reported once for each cranial lesion?

The code describes management of the complete one-session course for one or more cranial lesions, not a separate unit for each lesion.

What documentation supports 77432?

Document the cranial target or targets, that the complete course was delivered in one session, and the physician’s management, interpretation, and report.

How does 77432 differ from 77371?

77432 is the professional management service. 77371 represents the technical delivery for a complete single-session cranial stereotactic radiosurgery 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.
