CPT® Code 33863

Ascending aorta graft, with cardiopulmonary bypass, with aortic root replacement using valved conduit and coronary reconstruction (eg, Bentall)

The procedure described by CPT® Code 33863 involves a complex surgical intervention aimed at repairing conditions affecting the ascending aorta, specifically thoracic aortic aneurysms or dissections. This procedure is performed using a graft and requires the use of cardiopulmonary bypass, which temporarily takes over the function of the heart and lungs during surgery. The aortic root, which is the section of the aorta that connects to the heart and includes critical structures such as the aortic annulus, aortic valve leaflets, and coronary artery openings, is replaced using a valved conduit. The surgical approach typically involves a median sternotomy, allowing the surgeon to gain access to the heart and ascending aorta. The procedure is intricate, as it not only involves the replacement of the aortic root but also necessitates the reconstruction of the coronary arteries, ensuring that blood flow to the heart is maintained. The use of cardioplegic arrest is essential in this procedure, as it allows for a bloodless field and protects the heart during the surgical manipulation. Overall, this procedure is critical for patients with significant aortic pathology, aiming to restore normal function and prevent life-threatening complications.
