CPT® Code 37235

Add-On Code

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

The procedure described by CPT® Code 37235 involves the revascularization of an additional ipsilateral (same side) occluded or stenosed tibial or peroneal artery. This is achieved through endovascular techniques, which can be performed either openly or percutaneously. The process includes the use of angioplasty, atherectomy, and the placement of transluminal stents. Angioplasty is a method where a catheter with a balloon tip is advanced to the site of the blockage, and the balloon is inflated to compress plaque against the arterial wall, potentially requiring multiple inflations to achieve optimal results. Alternatively, atherectomy may be utilized, which involves a specialized catheter that shaves plaque from the artery using a cutting piston. This plaque is then collected within the device for removal after the procedure. Following these interventions, a completion angiography is performed to confirm the patency of the artery, and if necessary, a stent is deployed to maintain the artery's openness. This code is specifically used for each additional vessel treated in this manner, and it is important to note that it is billed separately in addition to the primary procedure code.
