Repair of oronasal fistula.
Modifiers may be applicable to indicate specific circumstances, such as increased procedural services (22), multiple procedures (51), or reduced services (52). Refer to current CPT guidelines for appropriate modifier usage.
Medical necessity for oronasal fistula repair is established by the presence of the fistula itself, along with associated symptoms such as nasal regurgitation of food or liquids, difficulty speaking, chronic rhinitis, or pain. The documentation should clearly establish the functional impairment caused by the fistula.
The physician is responsible for preparing the patient, administering anesthesia, performing the surgical repair of the fistula, and ensuring proper post-operative care.
In simple words: This procedure fixes a hole between the roof of your mouth and your nasal cavity. The surgeon creates a flap of tissue from nearby and uses it to cover the hole, stitching it in place.
Surgical repair of an oronasal fistula, an abnormal opening between the mouth and the nasal cavity through the maxillary hard palate.The procedure involves creating a flap of tissue, typically from the mucosa of the hard palate, and suturing it in layers to close the fistula.This may involve a single or double layer closure.
Example 1: A patient presents with an oronasal fistula following a tooth extraction. The fistula is small and is repaired using a single-layer closure with a local mucosal flap., A patient with a cleft palate develops an oronasal fistula.The fistula is larger and requires a more complex, multi-layered closure, possibly utilizing a buccal mucosal flap and a hard palate mucoperiosteal flap., A patient develops a chronic oronasal fistula due to advanced periodontal disease. The fistula repair involves a two-layer closure, with careful consideration given to the placement and vascularity of the tissue flaps to promote healing and prevent recurrence.
Documentation should include the size and location of the fistula, the method of repair (single or multi-layered closure, type of flap used), any associated procedures (e.g., tooth extraction), and post-operative instructions.
