Summary & Overview
CPT 21422: Intraoral Repair of Maxillary/Palatal Fracture
CPT code 21422 identifies intraoral surgical repair of fractures involving the maxilla or hard palate. This procedure is clinically significant because facial fractures often result from blunt trauma and may require timely operative intervention to restore function, occlusion, and facial structure. Nationally, accurate coding of maxillofacial fracture repair affects surgical quality reporting, hospital resource use, and payer claims adjudication.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for intraoral maxillary/palatal fracture repair, typical sites of service, and the billing challenges associated with operative facial trauma. The publication outlines common benchmarking and reimbursement themes, highlights areas where policy updates can influence coverage and billing practices, and clarifies coding boundaries relevant to surgical service lines.
The content equips administrators, coding professionals, and policy analysts with a clear description of the procedure represented by CPT code 21422, summarizes payer coverage scope, and identifies what information is available versus missing. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 21422 describes surgical treatment of a fracture of the maxilla (upper jaw) or the hard palate (roof of the mouth) performed through an intraoral incision. The procedure typically involves exposure, reduction, and internal fixation of facial bone fractures via an incision inside the mouth.

Clinical & Coding Specifications
Clinical Context
A 34-year-old male presents to the emergency department after an assault with blunt facial trauma. He reports facial pain, bleeding from the oral cavity, malocclusion, and inability to close his mouth comfortably. Physical exam demonstrates tenderness and step-off along the maxillary alveolar ridge and palate; intraoral laceration is present. CT of the facial bones confirms a displaced fracture of the maxilla involving the orbital floor and the hard palate (maxillary fracture of the roof of the mouth/upper jaw). The patient is taken to the operating room for open reduction and internal fixation via an intraoral approach under general anesthesia. The surgical team performs exposure through an incision in the oral mucosa, reduction of the maxillary fracture segments, and fixation with plates and screws. Postoperative care includes airway monitoring in the PACU, analgesia, antibiotics as indicated, instructions for oral hygiene, soft diet, and follow-up clinic visits with radiographic assessment.
