What 77762 covers

A radiation oncologist reports this service for intermediate-complexity placement of radioactive sources inside a body cavity for brachytherapy. A common setting is treatment of gynecologic cancer, such as cervical cancer, using an intracavitary applicator placed in the uterus or vagina. The work centers on applying the source through the cavity-based approach; it is distinct from placing sources within tissue or delivering high-dose-rate treatment categorized by channel count.

Select the intermediate level based on the documented complexity of the intracavitary application, not simply the diagnosis or treatment site. The operative or procedure note should describe the applicator and source placement and support why the service is intermediate rather than simple or complex. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. The service may be billed globally or with modifier 26 for the professional interpretation portion and modifier TC for the technical equipment and staff portion. Modifier 50 is inappropriate. Assistant-at-surgery payment requires medical-necessity documentation; 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.

77762 billing questions

How does this differ from 77761 or 77763?

These codes distinguish simple, intermediate, and complex intracavitary applications. The operative documentation should support the level of application performed; the treatment site alone does not determine the level.

Can the professional and technical portions be billed separately?

Yes. Modifier 26 identifies the professional interpretation portion, modifier TC identifies the technical equipment and staff portion, and billing without either modifier represents the global service.

Does this code have a global period?

Yes. CMS assigns a 90-day global period that includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

Can modifier 50 or an assistant surgeon be reported?

Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.

What documentation supports the intermediate level?

Document the intracavitary approach, applicator and source placement, and the procedural details that support an intermediate rather than simple 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 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.
