CPT code 34844 represents endovascular repair of the visceral aorta using a fenestrated endograft with placement of additional visceral artery endoprostheses. This complex, image-guided procedure preserves flow to the celiac, superior mesenteric, and renal arteries while excluding aneurysmal or diseased aortic segments. Nationally, the code captures high-acuity vascular interventions that carry significant resource use, specialized device costs, and multidisciplinary care pathways.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical description, typical sites of service, and the service type represented by the code. The publication provides benchmarking context for utilization and reimbursement (where available), summarizes relevant policy considerations for coverage and prior authorization, and clarifies clinical context for coders and administrators managing complex aortic endovascular procedures. Data not available in the input is noted where applicable, and the material is intended for national audiences involved in billing, revenue management, and clinical operations for vascular and endovascular services.
