CPT® Code 37233

Add-On Code

Revascularization, endovascular, open or percutaneous, tibial/peroneal artery, unilateral, each additional vessel; with atherectomy, includes angioplasty within the same vessel, when performed (List separately in addition to code for primary procedure)

The CPT® Code 37233 refers to the procedure of revascularization performed on an additional ipsilateral (same side) occluded or stenosed tibial or peroneal artery. This procedure can be conducted through either an open or percutaneous approach and involves the use of atherectomy, which is a technique that removes plaque from the arterial wall. The procedure also includes angioplasty within the same vessel when performed. The goal of this intervention is to restore blood flow to the affected artery, thereby improving circulation and alleviating symptoms associated with arterial occlusion or stenosis. During the procedure, a catheter with a balloon tip is advanced to the site of the occlusion, where it is inflated to compress the plaque against the artery wall. This may be done multiple times to achieve optimal results. Alternatively, atherectomy may be utilized, which involves a specialized catheter that shaves plaque from the artery. The procedure may also involve the placement of a stent to maintain the artery's patency. It is important to note that this code is used in conjunction with the primary procedure code and is listed separately for billing purposes.
