Summary & Overview
CPT 77469: Intraoperative Radiation Therapy during Surgery
CPT code 77469 represents the professional management of a complete course of intraoperative radiation therapy (IORT), in which radiation is delivered directly to an exposed tumor during surgery. This code captures a specialized radiation oncology service that combines surgical access with targeted radiotherapy to limit exposure to surrounding tissues and to consolidate treatment into the operative setting. Nationally, IORT is clinically important for select tumor types and surgical contexts where intraoperative delivery can reduce overall treatment time and focus dose to the tumor bed.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides a concise overview of coverage posture and reimbursement benchmarks across major commercial payers and the federal program, highlighting where policy differences commonly arise.

Billing Code Overview
CPT code 77469 describes management of a complete course of intraoperative radiation therapy (IORT). In this procedure, the provider administers radiation therapy by delivering irradiating X‑rays or electron beams directly to the exposed tumor during surgery. The service covers the radiation treatment delivered intraoperatively and the professional oversight of that course.
-
Service type: Intraoperative radiation therapy (IORT) delivered during a surgical procedure
-
Typical site of service: Operating room or intraoperative surgical suite
Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old with a localized soft tissue sarcoma of the retroperitoneum or a recurrent breast carcinoma scheduled for tumor resection. After induction of general anesthesia and surgical exposure, the surgical oncologist and radiation oncologist coordinate to deliver a single high-dose intraoperative radiation therapy (IORT) treatment directly to the tumor bed using either electron beam or orthovoltage X‑ray equipment. The radiation oncologist manages the complete intraoperative radiation course, including patient positioning, selection of applicator or cone, dose prescription, shielding of adjacent normal tissues (using lead/shields or packing), real‑time dosimetry checks, and documentation of delivered dose and field. Nursing and anesthesia personnel facilitate sterile access and hemodynamic monitoring. Typical workflow steps: preoperative planning and consent, multidisciplinary time‑out in the operating room, tumor resection or debulking by the surgeon, placement of applicator and shielding, delivery of IORT by the radiation oncology team, confirmation of dose delivery and treatment record completion, removal of applicator and closure of surgical site. Typical site of service is the hospital operating room or an ambulatory surgery center when equipped for sterile IORT delivery. Service type: intraoperative radiation therapy management provided in the OR during a surgical procedure.
