CPT® Code 30545

The procedure described by CPT® Code 30545 involves the surgical repair of choanal atresia using a transpalatine approach. Choanal atresia is a congenital condition characterized by the obstruction of one or both posterior nasal passages, which can significantly impact breathing and feeding in infants. This condition arises from abnormal development during fetal growth, leading to a blockage that can be either bony or membranous in nature. The transpalatine approach is specifically indicated for cases of bilateral choanal atresia, particularly when the atresia is thick and bony, or when it is associated with other anomalies affecting the anterior nasal cavities or nasopharynx. The surgical technique involves making an incision in the mucosa of the hard palate, allowing access to the underlying structures. The procedure aims to create a functional passageway for airflow, thereby alleviating the symptoms associated with this congenital anomaly. The careful dissection and removal of bone and tissue are critical to ensure that the new choanal openings are adequately formed and maintained, facilitating normal respiratory function post-surgery.
