CPT® Code 34843

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

The CPT® Code 34843 refers to the endovascular repair of the visceral aorta, which encompasses various conditions such as aneurysms, pseudoaneurysms, dissections, penetrating ulcers, intramural hematomas, or traumatic disruptions. This procedure utilizes a fenestrated visceral aortic endograft, a specialized type of prosthesis designed to treat defects in the aorta that extend into or above the branches of the visceral arteries. The fenestrated endograft features openings at the ostia of the superior mesenteric, celiac, and/or renal arteries, allowing for the uninterrupted flow of blood into these critical branches. The procedure is initiated with an incision in the groin to access the femoral artery, followed by the placement of a trocar and the advancement of a guidewire through the arterial system into the aorta. The guidewire is maneuvered through the aortic defect to a position just above the proximal aspect of the defect, facilitating the introduction of the endograft. The deployment of the endograft is performed under fluoroscopic guidance, ensuring that the fenestrations align correctly with the visceral arteries. This meticulous process is crucial for the successful repair of the aortic defect while maintaining blood flow to the visceral branches. The procedure also includes the placement of stents through the ostia of the involved visceral arteries, further securing the repair and ensuring the patency of these vessels. Overall, CPT® Code 34843 captures the complexity and precision involved in the endovascular repair of the visceral aorta using advanced techniques and technologies.
