Billing code 77762: Intracavitary radiationMedicare rate & RVUs

Medicare pays $558.46 for 77762 nationally in the office. Local office rates run $502.63–$733.60.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
