Official Description

Repair choanal atresia; intranasal

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

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.

1. Indications

The procedure described by CPT® Code 30540 is indicated for the surgical repair of choanal atresia, a condition that may present with the following symptoms or conditions:

  • Respiratory Distress: Newborns may exhibit difficulty breathing, particularly when feeding, due to the obstruction of the nasal passages.
  • Failure to Breathe Normally: Infants may struggle to breathe through the nose, leading to reliance on oral breathing, which can be inadequate.
  • Recurrent Respiratory Infections: The obstruction can lead to increased susceptibility to infections in the upper respiratory tract.
  • Congenital Anomalies: Choanal atresia may be associated with other congenital anomalies of the anterior nasal cavities or nasopharynx.

2. Procedure

The surgical procedure for repairing choanal atresia using CPT® Code 30540 involves several detailed steps:

  • Step 1: The procedure begins with the administration of a local anesthetic to the nasal area to ensure the patient is comfortable and pain-free during the surgery.
  • Step 2: A nasal speculum is then inserted into the nostril to allow the surgeon to visualize the site of the atresia clearly.
  • Step 3: An operating microscope is introduced to provide enhanced magnification and illumination, allowing for precise identification of the atretic membrane.
  • Step 4: A curved incision is made in the mucosa to create an anterior mucosal flap, which is then elevated to expose the underlying structures.
  • Step 5: The surgeon carefully removes bone by drilling parallel to the hard palate, taking care to avoid damage to surrounding anatomical structures.
  • Step 6: The atretic plate is penetrated to expose the nasopharyngeal mucosa, facilitating access to the obstructed area.
  • Step 7: The opening is enlarged by drilling into the vomer, pterygoid plate, and hard palate to ensure adequate airflow through the nasal passages.
  • Step 8: Posterior mucosal flaps are created, rotated, and laid down adjacent to the previously created anterior flaps, which are then imbricated to secure the new structure.
  • Step 9: Finally, stents are placed and secured in the newly created choanal opening to maintain its patency and ensure proper healing.

3. Post-Procedure

After the completion of the choanal atresia repair, patients typically require careful monitoring to assess for any complications. Post-procedure care may include the management of pain and discomfort, as well as instructions for nasal care to prevent infection. Patients may also need follow-up visits to ensure that the stents remain in place and that the new choanal openings are healing properly. The expected recovery period can vary, but close observation is essential to ensure that normal respiratory function is restored and maintained.
