CPT® Code 35571

The CPT® Code 35571 refers to a surgical procedure known as a bypass graft using a vein, specifically targeting the popliteal artery and its branches, including the tibial and peroneal arteries, or other distal vessels. This procedure is typically indicated for patients with significant arterial occlusion or blockage that impairs blood flow to the lower leg and foot. The surgery involves making an incision on the affected side behind the knee to expose the popliteal artery, which is a major blood vessel supplying the lower leg. The procedure entails creating a bypass route for blood flow by using a vein graft, often harvested from the saphenous vein in the leg. The process includes careful dissection and ligation of the vein, followed by anastomosis, which is the surgical connection of the graft to the popliteal artery and the distal artery. This technique is crucial for restoring adequate blood circulation, alleviating symptoms such as pain or claudication, and preventing complications associated with poor blood flow, such as tissue necrosis or limb loss.
