CPT® Code 36015

The CPT® Code 36015 refers to the procedure of selective catheter placement in a segmental or subsegmental pulmonary artery. This procedure involves the introduction of a catheter into the vascular system, specifically targeting the pulmonary arteries that branch off from the main pulmonary artery. The process begins with the insertion of a catheter into 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. A small incision is made at the chosen venous access point to facilitate the placement of an introducer sheath, which allows for the safe passage of a guidewire into the venous system. Once the guidewire is in place, it is navigated through the femoral and iliac veins, advancing into the inferior vena cava and subsequently reaching the right atrium of the heart. A pigtail catheter, equipped with a tip deflecting wire, is then advanced over the guidewire into the right atrium. The guidewire is removed, and the catheter may either remain in the right atrium or be further advanced into the right ventricle and main pulmonary artery. In the context of CPT® Code 36015, the focus is on the selective catheterization of the segmental or subsegmental pulmonary arteries, which are the smaller branches that extend from the main pulmonary artery into the lungs. This selective manipulation allows for targeted interventions, such as the injection of medication or radiopaque contrast, which may be necessary for diagnostic or therapeutic purposes. The procedure is critical for various clinical applications, including the assessment and treatment of pulmonary conditions.
