What 37294 covers

This code describes catheter-based treatment of a complex lesion in an initial tibial or peroneal artery vessel, combining atherectomy with stent placement. It is typically performed by an interventional radiologist, vascular surgeon, or interventional cardiologist in a hospital or other procedural setting. Angioplasty within the treated vessel is part of this revascularization service. The code is specific to the tibial/peroneal vascular territory; femoral or popliteal interventions belong to a different territory family.

Select the complex first-vessel code when the documented intervention meets the billing code criteria for complex treatment and includes both atherectomy and stenting. The operative report should identify the treated vessel, the intervention performed, and the basis for classifying the work as complex. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, CMS pays the highest-valued procedure in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

How to choose

37292Arterial revascularization

Both codes combine stenting and atherectomy in an initial tibial/peroneal vessel; 37292 is for the simple category, while 37294 is for the complex category.

37295Tibial revascularization

37294 reports the initial complex vessel. Use 37295 for an additional complex vessel rather than treating it as another initial-vessel service.

37290Peripheral atherectomy

37290 describes complex atherectomy without the combined stent service. Use 37294 when both atherectomy and stenting are performed in the vessel.

37286Venous stenting

37286 describes complex stenting without the combined atherectomy service. Use 37294 when atherectomy and stenting are both performed.
