What 37293 covers
This add-on code represents treatment of each additional tibial or peroneal artery using an endovascular approach that combines atherectomy with stent placement. Balloon angioplasty in the treated vessel, when performed, is part of the service. Vascular surgeons, interventional radiologists, and interventional cardiologists may perform these procedures for peripheral arterial disease, including disease associated with rest pain or tissue loss.
Report the code for an additional treated vessel when the intervention meets the straightforward category; it is not the code for the initial vessel. The operative report should identify the tibial or peroneal arteries treated and document the atherectomy and stent work. Angioplasty in that vessel is included rather than separately reported as another revascularization service. CMS classifies this as an add-on code: report it only with the applicable primary procedure, and its payment falls within that procedure's global period. For bilateral procedures, modifier 50 is paid at 150%.
