What 37289 covers
This add-on code describes catheter-based atherectomy in each additional tibial or peroneal artery vessel treated during lower-extremity endovascular revascularization. The intervention removes arterial plaque through an endovascular approach and is generally performed by an interventional radiologist, vascular surgeon, or cardiologist in an angiography suite or operating room. It is specific to additional vessels in the simple-procedure category; it does not describe the initial vessel or a combined atherectomy-and-stent service.
Report 37289 with the primary procedure for the initial vessel, typically 37288, when documentation supports atherectomy in an additional vessel and the applicable simple category. The operative report should identify the treated vessels and describe the atherectomy performed in each. As an add-on code, it is billed only with a primary procedure and paid within that procedure’s global period. For a bilateral procedure reported with modifier 50, CMS pays this code at 150%.
