Summary & Overview
CPT 34704: Aorto–Uni–Iliac Endograft Repair of Infrarenal Aorta or Iliac Artery
CPT code 34704 represents the endovascular placement of an aorto–uni–iliac endograft to repair the infrarenal aorta or an iliac artery for nonrupture indications. This comprehensive procedure code bundles preprocedure sizing and device selection, nonselective catheterization, adjunctive angioplasty or stenting, any necessary endograft extensions from the renal arteries to the iliac bifurcation, and radiological supervision and interpretation. Nationally, this procedure is an important element of minimally invasive aortic and iliac aneurysm and occlusive disease management, affecting hospital resource allocation, device utilization, and specialty reimbursement.
Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and coding scope for 34704, expected sites of service, and typical service components captured by the code. The publication outlines benchmarks and utilization patterns where available, highlights relevant payment and policy considerations affecting coverage and billing, and situates the code within common vascular service lines. Data not available in the input is noted where applicable; the narrative focuses on national implications rather than state-level specifics.
Billing Code Overview
CPT code 34704 describes placement of an aorto–uni–iliac endograft to repair the infrarenal aorta or an 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 in association with the repair, any endograft extensions from the renal arteries to the iliac bifurcation, and all radiological supervision and interpretation performed during the procedure.
Service type: Endovascular aortic/iliac repair using an aorto–uni–iliac endograft
Typical site of service: Hospital-based vascular interventional suite or hybrid operating room, often performed by vascular surgery or interventional radiology teams.
Clinical & Coding Specifications
Clinical Context
A 74-year-old male with a history of hypertension, hyperlipidemia, and peripheral arterial disease presents with an enlarging infrarenal abdominal aortic aneurysm measuring 5.8 cm on surveillance imaging. The vascular surgery team elects endovascular repair with an aorto–uni–iliac endograft because of unilateral iliac anatomy that precludes a bifurcated device and the presence of a contralateral occluded iliac artery. Preoperative workflow includes vascular laboratory duplex and CTA for sizing, device selection and planning, anesthesia assessment, and informed consent. In the operating room or hybrid suite the operator performs access via common femoral artery cutdown or percutaneous access, obtains angiographic imaging, performs pre-deployment balloon angioplasty if needed, deploys an aorto–uni–iliac endograft extending from the infrarenal aortic neck to the ipsilateral iliac artery, and commonly completes a femoral–femoral bypass (extra-anatomic) or iliac limb extension as necessary. The procedure includes intraoperative radiological supervision and interpretation, any nonselective catheterizations, and completion angiography to confirm graft position and seal. Typical postprocedure care includes monitoring in a PACU or step-down unit, surveillance imaging before discharge or at first follow-up, and anticoagulation/antiplatelet management as indicated.
