CPT® Code 37232

Add-On Code

Revascularization, endovascular, open or percutaneous, tibial/peroneal artery, unilateral, each additional vessel; with transluminal angioplasty (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 37232 involves the revascularization of an additional occluded or stenosed tibial or peroneal artery on the same side of the body (ipsilateral) through endovascular techniques. This procedure is performed either through an open approach or percutaneously, meaning it can be done through a small incision or puncture in the skin. The primary goal of this intervention is to restore blood flow to the affected artery, which may be compromised due to plaque buildup or narrowing (stenosis). The physician utilizes angioplasty, a method that involves the use of a balloon catheter to expand the artery, thereby compressing the plaque against the arterial wall to improve blood flow. In addition to angioplasty, the procedure may also involve atherectomy, which is a technique that removes plaque from the artery using a specialized catheter equipped with a cutting mechanism. This cutting piston shaves off the plaque, allowing for a clearer passage for blood flow. The physician may perform multiple passes with the atherectomy device to ensure thorough plaque removal. Following these interventions, a completion angiography is conducted to confirm that the artery is open and blood flow is restored. If necessary, a stent may be placed to maintain the artery's patency, ensuring that it remains open after the procedure. This code is specifically used to report each additional tibial or peroneal artery treated with angioplasty, and it is important to note that it is listed separately in addition to the primary procedure code.
