Summary & Overview
CPT 21249: Maxilla or Mandible Reconstruction with Metallic Implant
CPT code 21249 represents complex reconstructive surgery of the entire maxilla or mandible involving placement of a metallic implant into the jaw bone to restore form and function. Nationally, this code captures high-complexity maxillofacial reconstructive care used for large defects from trauma, tumor resection, or congenital anomalies and is relevant to hospital surgical services, oral and maxillofacial surgery departments, and payers managing high-cost surgical episodes. Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for the procedure, typical sites of service, and the payer mix covered; benchmarks for utilization and reimbursement are not included in the input. The publication summarizes common billing considerations and operational settings for the service line, highlights where this code fits within maxillofacial surgical care, and identifies which payers are commonly involved in coverage and claims adjudication. Data not available in the input includes specific utilization metrics, payer-specific reimbursement rates, ICD-10 pairings, and associated taxonomies.
Billing Code Overview
CPT code 21249 describes surgical reconstruction of the entire maxilla or mandible, where the provider inserts a metallic implant within the jaw bone to repair defects that impair jaw function. This procedure addresses extensive structural deficits of the upper or lower jaw that affect mastication, speech, or facial support.
-
Service type: Major reconstructive maxillofacial surgery
-
Typical site of service: Inpatient hospital or ambulatory surgical center equipped for complex craniofacial and oral-maxillofacial procedures
Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old individual with extensive maxillofacial bone loss of the maxilla or mandible from tumor extirpation, severe trauma, osteoradionecrosis, or congenital deformity that results in significant functional impairment of mastication, speech, or airway support. The surgical team, typically led by an oral and maxillofacial surgeon or a head and neck reconstructive surgeon, evaluates the patient preoperatively with clinical exam, computed tomography (CT) or cone-beam CT imaging, dental models, and multidisciplinary input from prosthodontics and otolaryngology when needed. The operative plan may include fabrication of custom metallic implants or reconstruction plates, possible bone grafting, implant fixation to the jaw bone, and intraoperative navigation.
Perioperative workflow includes preoperative medical clearance, anesthesia assessment, intraoperative placement of the metallic jaw implant with fixation to remnant bone to restore continuity and function, immediate or delayed soft-tissue closure, and postoperative monitoring for infection, hardware exposure, or implant failure. Postoperative care includes pain management, antibiotics as indicated, wound care, dietary modifications, and staged prosthodontic rehabilitation for dental occlusion and function.
