What 77763 covers

This service covers complex placement of a radiation source within a body cavity for brachytherapy. A radiation oncologist typically performs the application, often in a hospital or other treatment setting. Gynecologic cancers involving sites such as the cervix or vagina are common clinical contexts for intracavitary treatment. The application is distinct from the subsequent delivery of radiation by a high-dose-rate remote afterloading system.

Choose this level when the documented application is complex rather than simple or intermediate; the record should support the treated site, the intracavitary approach, and the work involved in positioning the source or applicator. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. The service has professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and no modifier represents the global service. Modifier 50 is inappropriate for this service. An assistant is payable only when medical necessity is documented; co-surgeons and team surgery are not permitted.

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.

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.
