CPT® Code 36013

The procedure described by CPT® Code 36013 involves the introduction of a catheter into the right heart or the main pulmonary artery. This is a critical procedure often performed to facilitate further diagnostic or therapeutic interventions. A catheter is a thin, flexible tube that can be inserted into the body to access various vascular structures. In this case, the catheter is introduced through a vein, typically the right femoral vein, although alternative sites such as the left femoral vein or an upper extremity vein may also be utilized. The procedure begins with a small incision at the chosen venous insertion site, allowing for the placement of an introducer sheath. This sheath serves as a conduit for the catheter, which is guided through the venous system into the heart. Once the catheter reaches the right atrium, it can be advanced into the right ventricle and subsequently into the main pulmonary artery. This access is crucial for various diagnostic purposes, including measuring pressures within the heart and pulmonary circulation, as well as for therapeutic interventions such as the administration of medications or contrast agents. The procedure may also involve selective catheterization of the left or right pulmonary arteries or even segmental or subsegmental branches, which are smaller arteries that branch off within the lungs. The ability to navigate these vascular structures allows for targeted treatment and assessment of pulmonary conditions. Overall, the introduction of a catheter into the right heart or main pulmonary artery is a fundamental procedure in interventional cardiology and pulmonary medicine, enabling a range of diagnostic and therapeutic options.
