CPT® Code 35482

Deleted

The CPT® Code 35482 refers to a specific medical procedure known as transluminal peripheral atherectomy, which is performed on the iliac artery. This procedure is designed to remove plaque buildup from the arterial walls, thereby improving blood flow. The term "transluminal" indicates that the procedure is conducted within the lumen of the artery, and "atherectomy" refers to the surgical removal of atherosclerotic plaque. In this case, the physician begins by preparing the skin over the access artery and making an incision to expose the artery. Following this, a sheath is placed into the artery to facilitate the insertion of a guidewire. The guidewire is then advanced through the artery to the site of the occlusion. An atherectomy catheter, which is a specialized device equipped with a cutting piston, is advanced over the guidewire. This catheter is designed to shave away the plaque from the arterial wall as it is maneuvered through the artery. The plaque is collected in the device and removed once the procedure is completed. The physician may perform multiple passes with the atherectomy device to ensure thorough removal of the plaque. After the atherectomy is completed, an angiography catheter is used to assess the success of the procedure through completion angiography, which involves injecting contrast material to visualize the artery. Finally, the access artery is repaired, and the skin incision is closed, marking the end of the procedure.
