CPT® Code 35483

Deleted

The CPT® Code 35483 refers to a specific medical procedure known as open transluminal peripheral atherectomy, specifically targeting the femoral-popliteal artery. This procedure is performed to remove plaque buildup from the arterial walls, which can obstruct blood flow and lead to various vascular complications. The term "transluminal" indicates that the procedure is conducted within the lumen of the artery, allowing for direct access to the blockage without the need for extensive surgical intervention. The process begins with the preparation of the skin over the access artery, followed by an incision to expose the artery. A sheath is then placed into the artery to facilitate the introduction of a guidewire, which is essential for navigating to the site of the occlusion. The atherectomy catheter, equipped with a specialized cutting mechanism, is advanced over the guidewire to perform the actual plaque removal. This cutting piston shaves the plaque from the arterial wall, effectively reducing the obstruction and restoring blood flow. The procedure may involve multiple passes with the atherectomy device to ensure thorough plaque removal. Following the atherectomy, an angiography catheter is utilized to perform a completion angiography, confirming the patency of the vessel before concluding the procedure with the repair of the access artery and closure of the skin incision.
