CPT® Code 36466

Injection of non-compounded foam sclerosant with ultrasound compression maneuvers to guide dispersion of the injectate, inclusive of all imaging guidance and monitoring; multiple incompetent truncal veins (eg, great saphenous vein, accessory saphenous vein), same leg

The CPT® Code 36466 refers to the procedure involving the injection of a non-compounded foam sclerosant into multiple incompetent truncal veins, such as the great saphenous vein and accessory saphenous vein, located in the same leg. This procedure is performed to treat chronic venous insufficiency, a condition characterized by poor blood flow in the veins of the legs, which can lead to symptoms such as pain, skin discoloration, inflammation, and the formation of ulcers. The use of ultrasound guidance is a critical component of this procedure, as it allows for precise identification of the target veins and ensures accurate dispersion of the sclerosant. The sclerosant works by inducing vasospasm and damaging the venous endothelium, ultimately leading to the replacement of the affected vessel with fibrous connective tissue. This process helps to minimize the chances of the vessel reopening, thereby providing a long-term solution to the issues associated with chronic venous insufficiency. The procedure concludes with the application of a compression bandage or garment to support the treated area and promote healing.
