CPT® Code 33788

The procedure described by CPT® Code 33788 involves the reimplantation of an anomalous pulmonary artery, which is a condition where the pulmonary artery is incorrectly positioned or connected. In this surgical intervention, the anomalous pulmonary artery, which arises from the aorta instead of its normal origin, is surgically reattached to the main pulmonary artery. This procedure is critical for restoring proper blood flow from the heart to the lungs, ensuring that oxygenated blood can be effectively delivered throughout the body. Access to the heart is typically achieved through a median sternotomy or thoracotomy, which are surgical techniques that involve making incisions in the chest to provide the surgeon with a clear view and access to the heart and surrounding structures. During the operation, the thymus gland may be removed, and the pericardium, which is the protective sac surrounding the heart, is incised to allow for better access to the heart's anatomy. The surgeon meticulously dissects the ascending aorta, the anomalous pulmonary artery, and the main pulmonary artery from the surrounding tissues to prepare for the reimplantation. The anomalous pulmonary artery is then ligated and divided, followed by an incision in the main pulmonary artery where the anomalous artery is anastomosed, or surgically connected, to it. If direct anastomosis is not feasible due to anatomical constraints, an interposition graft may be utilized to bridge the connection. Finally, the chest incisions are closed, and chest tubes may be placed to facilitate drainage and prevent fluid accumulation post-surgery.
