CPT® Code 36476

Add-On Code

Endovenous ablation therapy of incompetent vein, extremity, inclusive of all imaging guidance and monitoring, percutaneous, radiofrequency; subsequent vein(s) treated in a single extremity, each through separate access sites (List separately in addition to code for primary procedure)

Endovenous ablation therapy of incompetent veins is a minimally invasive procedure performed on the extremities to treat varicose veins and other venous insufficiencies. This specific technique utilizes radiofrequency energy to close off incompetent veins, which are veins that are unable to effectively return blood to the heart due to valve dysfunction. The procedure is conducted percutaneously, meaning it is performed through the skin, and involves the use of imaging guidance to accurately locate and treat the targeted vein. The process begins with the preparation of the treatment site, followed by the administration of local anesthesia to ensure patient comfort. A small incision is made to access the vein, and a series of specialized instruments, including a guidewire and a radiofrequency ablation catheter, are used to deliver the treatment. The procedure is designed to be efficient and effective, allowing for the treatment of multiple veins in a single session, provided they are accessed through separate entry points. This code, CPT® 36476, specifically refers to the treatment of subsequent veins in the same extremity after the primary vein has been addressed, ensuring that each treated vein is documented and billed appropriately.
