CPT code 37265 represents angioplasty (balloon dilation) of a complex occlusive lesion in the femoral and popliteal arterial territory, covering procedures in the common femoral/profunda femoris and superficial femoral/popliteal vessels. The code includes all access, catheterization, lesion crossing, and imaging guidance required to perform the intervention, and applies to either percutaneous or open approaches. This procedure is a core component of peripheral arterial disease management and has national relevance due to the prevalence of lower-extremity arterial occlusive disease and the resource intensity of endovascular interventions.

Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find benchmarks for utilization and reimbursement patterns across major payers, clinical context on when a complex femoral-popliteal angioplasty is reported, and relevant policy considerations affecting coverage and site-of-service determinations. The publication outlines typical settings where the service is performed (hospital outpatient departments, operating rooms, and interventional suites) and summarizes implications for billing and care coordination. Data not available in the input is explicitly noted where detailed payer-specific rates, modifiers, taxonomies, and diagnosis code mappings would otherwise be expected.
