CPT® Code 37230

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

The procedure described by CPT® Code 37230 involves the revascularization of a tibial or peroneal artery that has become occluded or narrowed due to stenosis. This is achieved through an endovascular approach, which can be performed either openly or percutaneously. The primary goal of this procedure is to restore blood flow to the affected artery, thereby improving circulation in the lower extremities. The physician utilizes techniques such as angioplasty, atherectomy, and the placement of a transluminal stent to achieve this goal. In the open approach, the skin over the access artery is carefully prepped and incised to expose the artery, while in the percutaneous approach, a needle is used to puncture the skin and access the artery, typically through one of the femoral arteries. Once access is obtained, a guidewire is navigated into the occluded artery under radiological supervision, allowing for the advancement of a catheter with a balloon tip to the site of blockage. The balloon is inflated to compress plaque against the arterial wall, which may be repeated multiple times to ensure optimal results. Alternatively, atherectomy may be performed, which involves using a specialized catheter to shave plaque from the artery. After the plaque is removed, a completion angiography is conducted to confirm that the artery is patent. If necessary, a stent is deployed to maintain the artery's patency, followed by the removal of all catheters and appropriate closure of the access site. This comprehensive approach ensures that the blood flow is restored effectively, addressing the underlying issues of arterial occlusion or stenosis.
