CPT® Code 34846

Endovascular repair of visceral aorta and infrarenal abdominal aorta (eg, aneurysm, pseudoaneurysm, dissection, penetrating ulcer, intramural hematoma, or traumatic disruption) with a fenestrated visceral aortic endograft and concomitant unibody or modular infrarenal aortic endograft and all associated radiological supervision and interpretation, including target zone angioplasty, when performed; including two visceral artery endoprostheses (superior mesenteric, celiac and/or renal artery[s])

The procedure described by CPT® Code 34846 involves the endovascular repair of the visceral aorta and the infrarenal abdominal aorta, specifically targeting conditions such as aneurysms, pseudoaneurysms, dissections, penetrating ulcers, intramural hematomas, or traumatic disruptions. This complex intervention utilizes a fenestrated visceral aortic endograft, which is designed with openings (fenestrations) that align with the ostia of the superior mesenteric, celiac, and/or renal arteries, allowing for uninterrupted blood flow to these critical branches. In conjunction with the fenestrated endograft, a unibody or modular infrarenal aortic endograft is also employed to ensure comprehensive coverage of the aortic defect. The procedure is performed under radiological supervision, which includes the interpretation of imaging studies to guide the placement of the endografts. Additionally, if necessary, target zone angioplasty may be performed to optimize the repair. The procedure is intricate and requires precise placement of two visceral artery endoprostheses to effectively manage the vascular pathology while minimizing the risk of complications.
