CPT 34848: Fenestrated Endograft Repair of Visceral Aorta

CPT code 34848 represents a complex endovascular aortic repair using a fenestrated endograft to treat disease of the visceral aorta, with concurrent infrarenal endograft placement and four visceral artery endoprostheses. This procedure is used for anatomies involving the celiac, superior mesenteric, and renal arteries, and addresses challenging aneurysmal or dissection pathology that threatens visceral perfusion. Nationally, the code captures high-acuity vascular interventions with significant resource use and specialized device considerations.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, an explanation of typical sites of service and service type, and an overview of items commonly examined in reimbursement and policy reviews: coding intent, device and supply implications, and billing complexity. The publication highlights benchmarks and payment-policy levers relevant to complex endovascular aortic repairs, as well as operational considerations such as site-of-service designation and the impact of device configurations on coding. Data not available in the input will be indicated where applicable.

Billing Code Overview

CPT code 34848 describes placement of a fenestrated endograft to repair the visceral aorta, performed under radiological guidance. The procedure includes deployment of a fenestrated endovascular graft in the upper abdominal aorta to accommodate the celiac, superior mesenteric, and renal arteries, placement of a one-piece or multiple-piece endograft in the infrarenal aorta, and placement of four additional visceral artery endoprostheses.

Service Type: Endovascular aortic repair with fenestrated endograft and visceral artery stenting

Typical Site of Service: Hospital inpatient or hospital outpatient interventional suite

Clinical & Coding Specifications

Clinical Context

A 72-year-old male with a symptomatic thoracoabdominal aortic aneurysm involving the visceral segment presents with increasing abdominal pain and a known expanding aneurysm on surveillance imaging. Cross-sectional CT angiography demonstrates an infrarenal extension with involvement of the visceral aorta at the level of the celiac trunk, superior mesenteric artery (SMA), and both renal arteries. Endovascular repair with a fenestrated endograft is planned under radiologic guidance to exclude the aneurysm sac while preserving visceral perfusion. The procedure is performed in an interventional radiology or hybrid operating room environment with the patient under general anesthesia. Access is obtained via bilateral common femoral arterial cutdowns or percutaneous access. Under fluoroscopic and angiographic guidance, a fenestrated main aortic endograft is positioned to align fenestrations with the celiac, SMA, and renal ostia; an infrarenal aortic component is deployed as needed. Four additional visceral artery endoprostheses (branch stents) are advanced into the visceral vessels through the fenestrations and deployed to secure flow into each target artery. Completion angiography confirms exclusion of the aneurysm, patency of visceral branches, and absence of endoleak. Post-procedure care includes overnight intensive or step-down monitoring, serial vascular checks, and post-operative imaging per institutional protocol. Typical pre- and post-procedure documentation includes informed consent, operative report specifying 34848, device lot numbers, fluoroscopy time, blood loss estimate, and any adjunctive procedures or complications.
