CPT® Code 33902

Percutaneous pulmonary artery revascularization by stent placement, identified by CPT® Code 33902, is a specialized procedure aimed at addressing stenotic lesions within the pulmonary artery that have not responded adequately to balloon angioplasty. This intervention is particularly relevant for patients with abnormal vascular connections, which may include congenital heart defects or surgically altered anatomy. The procedure is performed under general anesthesia and utilizes fluoroscopic guidance to ensure precision during the intervention. The approach typically involves accessing the vascular system through a large vein, with the specific access site determined by the patient's unique anatomical considerations. The use of endovascular stents provides a more stable and supportive structure for the affected vessel, thereby improving blood flow and reducing the risk of complications associated with stenosis. The procedure is comprehensive, involving diagnostic angiograms to assess the extent of the stenosis and the selection of appropriately sized stents and balloons for effective treatment. This method not only enhances the immediate management of pulmonary artery stenosis but also plays a crucial role in the long-term care of patients with complex congenital heart conditions.
