CPT® Code 37231

Revascularization, endovascular, open or percutaneous, tibial, peroneal artery, unilateral, initial vessel; with transluminal stent placement(s) and atherectomy, includes angioplasty within the same vessel, when performed

The procedure described by CPT® Code 37231 involves the revascularization of a tibial or peroneal artery that has become occluded or narrowed due to conditions such as atherosclerosis. This revascularization can be performed through either an open surgical approach or a percutaneous (minimally invasive) technique. The primary goal of this procedure is to restore blood flow to the affected artery, which is crucial for maintaining proper circulation in the lower extremities. The physician utilizes a combination of techniques, including angioplasty, atherectomy, and the placement of a transluminal stent, to achieve this goal. Angioplasty involves the use of a balloon catheter to dilate the narrowed artery, while atherectomy involves the removal of plaque from the arterial wall using a specialized device. The placement of a stent helps to keep the artery open after the procedure. This comprehensive approach ensures that the artery remains patent, thereby improving blood flow and reducing the risk of complications associated with arterial occlusion. The procedure is performed under radiological supervision, allowing for precise navigation and intervention within the vascular system.
