CPT® Code 36005

The procedure described by CPT® Code 36005 refers to an injection procedure specifically for extremity venography. This diagnostic imaging technique is utilized to visualize the veins in the extremities, such as the arms and legs, to assess various medical conditions. A venogram is particularly useful in diagnosing or evaluating issues such as swelling and pain in an extremity, which may indicate underlying vascular problems. It is also employed to detect deep vein thrombosis (DVT), a serious condition where blood clots form in the deep veins, potentially leading to complications like pulmonary embolism. Additionally, this procedure can help identify the source of pulmonary emboli, congenital venous malformations, and other causes of venous obstruction that may affect blood flow. During the venography, the healthcare provider may also use this technique to locate a suitable vein for arterial bypass surgery, ensuring that the surgical procedure can be performed effectively. The process begins with the cleansing of the skin over the planned puncture site, typically located on the foot or hand, to minimize the risk of infection. A needle or intracatheter is then introduced into the vein, followed by the injection of a radiopaque contrast material, which enhances the visibility of the veins on imaging studies. To facilitate the filling of deep veins and improve the quality of the images obtained, a tourniquet may be applied above the ankle or on the lower arm to temporarily slow blood flow. Throughout the procedure, radiographs are taken at timed intervals to capture the flow of the contrast material through the venous system. After the procedure is completed, the intravenous access is flushed with a heparin and saline solution to maintain patency, and the needle or intracatheter is removed, with pressure applied to the site to prevent bleeding.
