CPT® Code 36471

The procedure described by CPT® Code 36471 involves the injection of a sclerosant into multiple incompetent veins located in the same leg, excluding telangiectasia. A sclerosant is a chemical agent that, when injected into a vein, causes irritation and inflammation of the vein walls. This leads to the veins sticking together and eventually closing off permanently. As a result, the treated varicose veins may become less visible or disappear altogether over time as the body naturally reabsorbs the affected tissue. Prior to the injection, the skin over the varicose veins is typically cleansed with an antiseptic to minimize the risk of infection. The physician may also document the sites and extent of the varicosities through photography. During the procedure, the physician stretches the skin taut with one hand while injecting the sclerosant along the length of the vein with the other hand. Multiple injections are often necessary for each vein being treated, and the procedure aims to reroute venous blood flow to deeper veins, thereby improving venous circulation in the affected leg.
