CPT® Code 36470

The procedure described by CPT® Code 36470 involves the injection of a sclerosant into a single incompetent vein, which is a vein that is unable to properly transport blood due to valve failure. This procedure is specifically indicated for veins that are not classified as telangiectasia, which are small, superficial blood vessels. The sclerosant is a chemical agent that, when injected, causes irritation and inflammation of the vein walls. This reaction leads to the veins sticking together and eventually closing off permanently. As a result, the treated varicose veins may gradually disappear or become less visible as the body naturally reabsorbs the affected tissue. The procedure is typically performed in an outpatient setting and may involve the documentation of the varicose veins through photography to assess the extent of the condition prior to treatment. Proper skin preparation, including cleansing with an antiseptic, is essential to minimize the risk of infection during the injection process. The physician employs a technique that involves stretching the skin taut to facilitate the injection of the sclerosant along the length of the vein, often requiring multiple injections for effective treatment of the vein.
