CPT code 37263 represents angioplasty (balloon dilation) of a straightforward stenotic lesion in an initial vessel of the femoral and popliteal vascular territory. This code captures the full procedure including access, catheterization, lesion crossing, and imaging guidance, and applies to percutaneous and open approaches. Nationally, peripheral endovascular interventions for femoropopliteal disease are common components of vascular care for patients with symptomatic peripheral artery disease and critical limb ischemia; accurate coding supports appropriate clinical documentation and claims processing.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and service settings, plus what to expect from payer coverage patterns and common billing considerations. The publication outlines benchmarks used in comparative analyses, recent coding policy clarifications that affect procedural bundling and site-of-service considerations, and related service-line implications for vascular surgery and interventional radiology practices.

This summary is intended to orient clinicians, billing staff, and policy analysts to the clinical scope of the code, typical sites of care, and the payer landscape relevant to CPT code 37263. Data not available in the input for specific modifiers, taxonomies, ICD-10 pairings, and related CPT codes is noted elsewhere in the full publication.
