CPT 34845: Fenestrated Endograft Repair of Visceral Aorta with Single Visceral Artery Endoprosthesis
CPT code 34845 covers a complex endovascular procedure: placement of a fenestrated endograft in the visceral aorta with an additional endoprosthesis placed in a single visceral artery. This code captures advanced, image-guided repair of the upper abdominal aorta when critical branch vessels (celiac, superior mesenteric, renal arteries) require preservation or incorporation into the repair. Nationally, the code represents high-acuity vascular care often performed in tertiary centers with hybrid operating rooms and specialized interventional teams.
Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of reimbursement benchmarks, common billing and documentation considerations, and the clinical context for when fenestrated endografts are used versus alternative open or standard endovascular repairs. The summary highlights policy and coding considerations that affect coverage and prior authorization processes, and it outlines the procedural elements codified by 34845 that clinicians and billers must document to support appropriate coding. Data not available in the input is noted where applicable.

Billing Code Overview
CPT code 34845 describes placement of a fenestrated endograft under radiological guidance to repair the visceral aorta (the upper abdominal aorta involving the celiac, superior mesenteric, and renal arteries). The procedure includes placement of either a single-piece or multi-piece endograft in the infrarenal aorta, with placement of an additional endoprosthesis in a single visceral artery.
Service type: Endovascular aortic repair with fenestrated endograft placement (complex endovascular vascular intervention).
Typical site of service: Hospital-based interventional radiology or vascular surgery suite, frequently performed in an operating room or hybrid operating room with fluoroscopic imaging and endovascular capabilities.
