CPT® Code 35474

Deleted

The CPT® Code 35474 refers to a specific medical procedure known as percutaneous transluminal balloon angioplasty, which is performed on the femoral-popliteal artery. This procedure is a minimally invasive technique used to treat blockages in the arteries that supply blood to the legs. During the angioplasty, a physician accesses the femoral artery, typically located in the groin area, to reach the affected artery. The procedure involves the insertion of a catheter with a balloon at its tip into the artery. Once positioned at the site of the blockage, the balloon is inflated, which compresses the plaque against the arterial wall, thereby widening the artery and restoring blood flow. This technique may require multiple inflations of the balloon to achieve optimal results. Following the angioplasty, a completion angiography is performed to confirm that the artery is open and blood flow is restored. This procedure is crucial for patients experiencing symptoms related to peripheral artery disease, as it can significantly improve circulation and alleviate pain associated with reduced blood flow to the lower extremities.
