CPT® Code 33901

Percutaneous pulmonary artery revascularization by stent placement, identified by CPT® Code 33901, is a specialized medical procedure aimed at treating stenotic lesions within the pulmonary artery. These lesions may not respond adequately to balloon angioplasty, necessitating the use of endovascular stents. Stents serve as a supportive structure, providing rigidity to the affected vessel and facilitating improved blood flow. The procedure is performed under general anesthesia and is guided by fluoroscopic imaging, which allows for real-time visualization of the heart and blood vessels. It is typically conducted during a cardiac catheterization procedure that may also address congenital defects in the right and/or left heart. Access to the vascular system is usually achieved through a large vein, although the specific access point may vary based on the individual patient's anatomy. The procedure begins with the application of lidocaine to numb the access site, followed by puncturing the vein to insert a guidewire and introducer sheath. A catheter is then advanced over the guidewire to reach the targeted area of the pulmonary artery. Initial diagnostic angiograms are performed to assess the size of the stenotic lesion and surrounding vessels, which informs the selection of the appropriate stent and balloon size for the intervention. This comprehensive approach ensures that the stent placement is tailored to the specific anatomical and pathological conditions of the patient, ultimately aiming to restore normal blood flow through the pulmonary artery.
