CPT 37259: Iliac Artery Stent Placement, Additional Vessel
CPT code 37259 represents stent placement in an additional iliac artery performed during the same session as an initial iliac revascularization. The code captures deployment of a mesh stent, with or without adjunctive angioplasty, for a straightforward iliac lesion and includes all access, catheterization, lesion crossing, and imaging guidance. Nationally, this code matters because iliac revascularization and staged or multitarget endovascular treatments are common in vascular surgery and interventional radiology, affecting procedural coding, bundling, and payment determinations across public and commercial payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what the code represents clinically, expected sites of service, and the service type. The publication also provides benchmarks and comparative policy context where available, guidance on common billing considerations for same-session additional-vessel stenting, and links to related procedure groupings. Data not available in the input is noted where applicable.
