CPT code 36217 represents selective catheterization of each third-order or smaller thoracic or brachiocephalic branch, generally performed to obtain angiographic visualization of small, distal arterial branches. This code is clinically important for diagnosing vascular disease in thoracic and brachiocephalic territories and may influence downstream diagnostic and therapeutic decisions. Nationally, utilization of detailed selective angiography supports precise lesion localization and procedural planning for endovascular or surgical interventions.

Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for CPT code 36217, the typical service setting, and which payers commonly cover such procedures. The publication outlines payment and coding benchmarks where available, summarizes relevant policy considerations that affect claim adjudication, and situates the code within common procedural workflows used by interventional radiology and vascular surgery teams.

This summary provides clinicians, billing professionals, and policy analysts with the operational context for CPT code 36217, including when the code applies, typical sites of service, and the types of diagnostic goals associated with selective third-order branch angiography.
