CPT code 34846 represents an endovascular repair of the visceral abdominal aorta using a fenestrated endograft and additional visceral artery endoprostheses. This complex, image-guided procedure addresses aneurysms or other pathologies affecting the aortic segment that gives rise to the celiac, superior mesenteric, and renal arteries. The code captures placement of a fenestrated main endograft with deployment of an infrarenal component and two visceral artery stents.

This code matters nationally because it reflects advanced endovascular aortic therapy with higher resource use, specialized devices, and multidisciplinary care in hospital interventional suites. Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Payer behavior on coverage and payment influences access to fenestrated endograft repair and device utilization across the United States.

Readers will learn the clinical scope of the code, typical care setting and service type, and the elements that make this procedure resource-intensive.
