CPT code 34847 represents a complex endovascular repair of the visceral aorta using a fenestrated endograft with placement of additional visceral artery endoprostheses. This technically demanding procedure addresses aneurysms or other pathologies involving the upper abdominal aorta and the major visceral branches (celiac, superior mesenteric, and renal arteries) and is performed under fluoroscopic guidance in hospital-based vascular or hybrid operating settings. Nationally, the code is important because it captures resource-intensive vascular interventions with implications for facility utilization, inpatient versus outpatient status, and payer policy development.

Key payers in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical service the code represents, typical sites of service, and how the code is used to capture complex fenestrated endograft repairs. The publication outlines common modifiers associated with this service and highlights the kinds of benchmarks and policy topics to review, such as reimbursement status across major payers, bundling and global period considerations, and documentation expectations needed to support medical necessity.
