CPT® Code 37222

Add-On Code

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

The CPT® Code 37222 refers to the procedure of revascularization of an additional ipsilateral iliac vessel through endovascular means, which can be performed either via an open or percutaneous approach. This procedure is specifically indicated for patients with occluded or stenosed iliac arteries, where the physician employs angioplasty techniques to restore blood flow. In the context of this procedure, 'revascularization' means the restoration of blood supply to the affected artery, which is crucial for preventing complications associated with reduced blood flow, such as ischemia. The term 'iliac artery' refers to the large arteries that supply blood to the pelvis and lower limbs, and 'ipsilateral' indicates that the procedure is performed on the same side of the body as the primary intervention. The use of transluminal angioplasty involves the insertion of a balloon catheter to dilate the narrowed artery, thereby compressing plaque against the arterial wall to improve blood flow. This code is used in conjunction with other related codes, such as 37220 for the initial iliac artery treated, and it is important to note that it is listed separately in addition to the primary procedure code. The detailed steps involved in this procedure ensure that the physician can effectively address vascular blockages while minimizing patient risk and promoting recovery.
