CPT code 34703 represents placement of an aorto–uni–iliac endograft to repair the infrarenal aorta or an iliac artery for nonrupture indications. This endovascular procedure encompasses device sizing and selection, nonselective catheterization, any adjunct angioplasty or stenting, endograft extensions from the renal arteries to the iliac bifurcation, and radiological supervision and interpretation. The code is clinically significant because it defines coverage and billing for a complex vascular intervention that substitutes for open repair in selected patients and carries material implications for facility, device, and imaging utilization nationwide.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for aorto–uni–iliac endograft procedures, typical settings of care, and the components of service bundled into CPT code 34703. The publication outlines benchmark considerations for reimbursement and utilization, highlights common billing modifiers used with complex vascular interventions, and summarizes policy and coding updates that affect national payment and documentation practices. Intended audiences include vascular surgeons, interventional radiologists, hospital billing teams, and payers seeking clarity on procedure definition and service components.
