What 37277 covers

This code represents catheter-based revascularization of a femoral or popliteal artery in which the operator performs atherectomy and places a stent in the treated vessel. Balloon angioplasty in that same vessel, when performed, is part of the revascularization service. Vascular surgeons, interventional radiologists, and interventional cardiologists commonly perform these procedures for peripheral arterial disease, including symptomatic limb ischemia, in a hospital or outpatient procedural setting.

Use the complex initial-vessel code when the documentation supports the complex category in the femoropopliteal revascularization family and identifies the treated vessel and both atherectomy and stent placement. The family separates initial-vessel services from services for additional vessels and distinguishes complex from simple procedures. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and the others 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.
