Brachytherapy

About 77761: Simple intracavitary brachytherapy application

Reports the simple-complexity application of an intracavitary radiation source, such as an applicator used for gynecologic brachytherapy.

Code 77761 represents the simple-complexity level of intracavitary brachytherapy source application. A radiation oncologist positions an applicator or source within a body cavity to provide localized radiation. A familiar clinical setting is gynecologic brachytherapy, with an applicator placed in the uterine or cervical region as part of a planned radiation course. The code level reflects application complexity, not the cancer diagnosis or radiation dose.

Select 77761 when the procedure documentation supports simple application rather than the intermediate or complex sibling level. Document the cavity, applicator and source arrangement, procedural details, and basis for the complexity level. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. Modifier 26 identifies the professional interpretation, modifier TC identifies the technical work, and an unmodified claim represents the global service. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

77761 billing questions

How is 77761 distinguished from 77762 or 77763?

These codes represent simple, intermediate, and complex application levels. Use the level supported by the documented procedure; do not select it based only on diagnosis or radiation dose.

Which modifiers identify the professional and technical portions?

Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical portion involving equipment and staff. The unmodified code represents the global service.

Does the 90-day global period include related follow-up care?

Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can modifier 50 be used for bilateral treatment?

No. CMS identifies bilateral adjustment as inappropriate for this code.

What documentation supports reporting the simple level?

Document the body cavity, applicator and source arrangement, procedure performed, and clinical details supporting simple rather than intermediate or complex application.

Where these rates come from

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.
