CPT® Code 37761

The procedure described by CPT® Code 37761 involves the ligation of perforator veins in one leg using an open subfascial technique. Perforator veins are critical structures that connect the deep venous system, specifically the femoral and popliteal veins, to the superficial saphenous veins in the legs. These veins can become incompetent, leading to chronic venous insufficiency, which is a condition characterized by poor blood flow and can result in venous ulcerations. The ligation procedure aims to treat these incompetent veins, thereby improving venous circulation and alleviating symptoms associated with venous insufficiency. The open subfascial technique allows for a more targeted approach, utilizing a smaller incision compared to other methods, and may incorporate ultrasound guidance to enhance the precision of locating and ligating the affected perforator veins. This technique is essential for ensuring that the ligation is performed effectively, minimizing complications, and promoting better recovery outcomes for patients suffering from severe venous issues.
