    CPT 37266: Angioplasty for Complex Femoral/Popliteal Lesion, Additional Vessel

    Medicare pays $2551 on average nationally for this procedure.

    CPT code 37266 describes angioplasty (balloon expansion) of a complex lesion (complete occlusion) in an additional vessel within the femoral and popliteal vascular territory performed at the same session as an initial femoral or popliteal revascularization; the service includes all access, catheterization, lesion crossing, and imaging guidance necessary to complete the procedure and may be performed via open or percutaneous approach. This is a procedural vascular intervention typically provided in the interventional radiology, vascular surgery, or endovascular suite and is billed as an add-on angioplasty for a separate complex lesion in the same femoral/popliteal vascular territory during the same session.

    For related coverage guidance, see recent payer policy updates: Cardiac Computed Tomography (CCT)/Coronary Computed Tomographic Angiography (CCTA), Cardiovascular Disease Risk Assessment, Biomarkers for Myocardial Infarction and Chronic Heart Failure.

    Clinical & Coding Specifications

    Clinical Context

    A 72-year-old male with progressive right lower-extremity claudication, non-healing toe ulcer, and rest pain is evaluated for peripheral arterial disease. Noninvasive testing (ABI, duplex ultrasound) and diagnostic angiography demonstrate multi-segment disease in the femoral-popliteal territory with a primary target lesion treated by an initial femoral or popliteal revascularization (open femoral endarterectomy or percutaneous transluminal angioplasty/stent of the index vessel). During the same session, the operator identifies a second complex lesion consisting of a chronic total occlusion (CTO) in an additional femoral or popliteal vessel. The provider performs balloon angioplasty of that additional complex lesion, including all arterial access, catheterization, lesion crossing maneuvers, guidewire and catheter use, and fluoroscopic imaging guidance required to complete the procedure. The patient is managed in an interventional suite or hybrid operating room with vascular surgery and interventional radiology capabilities, monitored for hemodynamic stability, access-site hemostasis, and distal perfusion post-procedure. Typical peri-procedural workflow includes informed consent, anticoagulation and/or antiplatelet management per institutional protocol, angiographic imaging, the index revascularization procedure, and the additional angioplasty of the complex lesion billed under 37266 during the same session.

    CPT CodeDescriptionRelationship to This Procedure
    37246Revascularization, endovascular, open or percutaneous, femoral/popliteal artery, single vessel; with transluminal balloon angioplastyOften represents the initial femoral/popliteal angioplasty procedure performed in the same session; 37266 describes angioplasty of an additional complex occluded vessel at the same session.
    37248Transcatheter placement of intravascular stent(s), peripheral arterial, open or percutaneous, initial vesselMay be performed after angioplasty if stent placement is required in the treated femoral or popliteal segment during the same session.
    37267At the same session as a femoral or popliteal revascularization service, angioplasty of an additional vessel, simple lesionUsed when the additional vessel lesion is simple rather than complex; distinct from 37266 which is for complex (occlusion) lesions.
    75962Transcatheter angiography, selective, limb, unilateral or bilateral, radiological supervision and interpretationUsed to report diagnostic and procedural angiographic imaging performed to guide the endovascular procedures including 37266.
    35831Endarterectomy, femoralMay be the open initial femoral revascularization performed in the same session before performing 37266 on an additional vessel.
