CPT® Code 36010

The CPT® Code 36010 refers to the procedure of introducing a catheter into the superior or inferior vena cava, which are major veins in the body responsible for returning deoxygenated blood to the heart. This procedure is commonly performed through access veins such as the brachial and cephalic veins. During the procedure, a small incision is made at the planned puncture site to facilitate access to the vein. An introducer sheath is then placed within the vein to allow for the safe passage of instruments. Following this, a guidewire is carefully advanced through the access vein and directed into either the superior or inferior vena cava. If the access point is through the brachial or cephalic vein, the guidewire and catheter are maneuvered through the superior vena cava, passing through the right atrium before reaching the inferior vena cava. This technique is essential for various medical interventions, including the administration of medications or radiopaque contrast agents, which may be injected as necessary during the procedure to enhance imaging or therapeutic effects.
