CPT code 77424 represents the technical component of intraoperative radiation therapy (IORT), where irradiating X‑rays are applied directly to an exposed tumor during surgery. This code captures the technical delivery of radiation at the time of operative tumor resection and is significant for coordinating perioperative oncology care, facility billing, and radiation therapy resource allocation. As IORT can concentrate dose to a targeted area while sparing surrounding tissues, accurate coding affects claims processing and national utilization tracking.

Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and coding intent, typical sites of service, and the payer landscape relevant to facility and radiation oncology billing. The publication outlines common modifiers and coding considerations, and highlights what benchmarks and policy updates to review when assessing reimbursement and compliance for IORT technical services.
