CPT® Code 33824

The procedure described by CPT® Code 33824 involves the surgical repair of a patent ductus arteriosus (PDA) in patients who are 18 years of age or older. The ductus arteriosus is a vital blood vessel that connects the descending aorta to the left pulmonary artery during fetal development, facilitating proper circulation in the womb. Typically, this vessel closes shortly after birth, which is a normal physiological process. However, in cases of patent ductus arteriosus, the ductus fails to close, leading to potential complications such as increased workload on the heart and damage to the lungs due to abnormal blood flow. The surgical approach to repair the PDA involves a posterolateral thoracotomy, which is an incision made in the chest to access the heart and surrounding structures. During the procedure, the surgeon may choose to suture ligate the ductus arteriosus, effectively tying it off, or utilize clips to close it. In some instances, the ductus may be both ligated and divided, which is a more definitive surgical intervention. It is important to note that this specific code, 33824, is designated for patients aged 18 years and older, distinguishing it from similar procedures performed on younger patients, which are coded differently.
