CPT® Code 30540

The procedure described by CPT® Code 30540 involves the surgical repair of choanal atresia, which is a congenital condition characterized by the obstruction of one or both posterior nasal passages due to a closure at the level of the anterior skull base. This condition can lead to significant respiratory difficulties, particularly in newborns, as it obstructs the normal airflow through the nasal passages. The repair is performed using an intranasal approach, which allows the surgeon to access the affected area directly through the nostrils. During the procedure, a local anesthetic is administered to ensure patient comfort. The surgeon utilizes a nasal speculum to visualize the site of atresia, followed by the insertion of an operating microscope for enhanced visibility of the atretic membrane. The surgical steps involve creating a mucosal flap, removing bone to access the nasopharyngeal mucosa, and enlarging the opening to restore normal airflow. The procedure concludes with the placement of stents to maintain the newly created choanal opening, ensuring that the airway remains unobstructed post-surgery. This meticulous approach aims to correct the anatomical defect and improve respiratory function in affected patients.
