Summary & Overview
CPT 21206: Maxillary Osteotomy, Upper Jaw Repositioning
CPT code 21206 represents a maxillary osteotomy — an operative procedure to incise and reposition the maxilla (upper jaw) to correct congenital or acquired facial deformities. This code matters nationally because maxillofacial corrective surgeries address functional issues such as malocclusion and airway compromise as well as significant cosmetic and quality-of-life concerns, and they involve complex surgical, perioperative, and post-acute care pathways that affect utilization and payment across payers.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and the service classification for 21206. The publication outlines common billing considerations and the landscape of coverage policy and reimbursement benchmarks across the major commercial payers and Medicare. It also summarizes procedural relevance for surgical practices and facility billing, providing clarity on where this service is typically performed and why accurate coding matters for care coordination and claims adjudication.
This summary is intended for national audiences including providers, billing professionals, and payer policy analysts seeking a clear reference on the clinical intent and billing classification of CPT code 21206.

Clinical & Coding Specifications
Clinical Context
A 24-year-old patient with congenital maxillary hypoplasia presents with malocclusion, midface deficiency, and impaired nasal airflow. After orthodontic preparation and multidisciplinary evaluation (oral and maxillofacial surgery, orthodontics, ENT), the patient is scheduled for a Le Fort I maxillary osteotomy to mobilize and advance the maxilla to correct occlusion, improve facial profile, and restore nasal airway function. The clinical workflow includes preoperative imaging (panoramic radiograph, CBCT), orthodontic alignment, operative planning with surgical models or virtual planning, general anesthesia in an operating room, intraoperative maxillary osteotomy with segmental mobilization and fixation, placement of intermaxillary fixation or elastics as indicated, postoperative inpatient or same-day recovery with analgesia and antibiotics, and follow-up with the surgical and orthodontic teams for healing and occlusal refinement.
