Summary & Overview
CPT 34703: Aorto–Uni–Iliac Endograft Placement for Infrarenal Aortic or Iliac Repair
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.
Billing Code Overview
CPT code 34703 describes placement of an aorto–uni–iliac endograft, a tubular endovascular graft that extends from the infrarenal aorta down one iliac limb to repair the infrarenal aorta or iliac artery for reasons other than rupture or injury. The code includes pre-procedure sizing and device selection, any nonselective catheterization, angioplasty or stenting performed as part of the repair, any endograft extensions from the renal arteries to the iliac bifurcation, and all radiological supervision and interpretation.
Service type: Endovascular aortic repair (aorto–uni–iliac endograft placement)
Typical site of service: Hospital inpatient or outpatient vascular/interventional radiology suite or hybrid operating room
Clinical & Coding Specifications
Clinical Context
A 74-year-old male with progressive abdominal and back pain undergoes surveillance imaging that demonstrates an infrarenal abdominal aortic aneurysm measuring 5.8 cm with unilateral common iliac artery involvement. The vascular surgery team schedules an endovascular repair using an aorto–uni–iliac (AUI) endograft because of unilateral iliac occlusive disease and inadequate distal landing on the contralateral side. Pre-procedure workflow includes informed consent, preoperative imaging review for device sizing, anesthesia evaluation, and operating room (hybrid suite) scheduling. Intra-procedure steps include vascular access (typically unilateral femoral), angiographic assessment, device introduction and deployment from the infrarenal aorta into the ipsilateral iliac artery, selective or nonselective catheterization as needed, placement of an occlusion device or coil on the contralateral common iliac origin and femoro–femoral bypass or staged contralateral revascularization if required. The service includes radiological supervision and interpretation of intraoperative angiography, any required angioplasty or stenting of iliac segments, and endograft extensions from the renal arteries to the iliac bifurcation as indicated. Typical post-procedure care involves recovery monitoring, postoperative imaging (duplex ultrasound or CT angiography), and discharge planning with antiplatelet therapy and follow-up surveillance.
