Summary & Overview
CPT 21453: Mandibular Fracture Repair with Intraoral Fixation
CPT code 21453 represents surgical repair of mandibular fractures using fixation devices attached to the teeth to stabilize the lower jaw during healing. This operative approach is a common intervention after blunt facial trauma and is clinically significant due to its impact on airway management, occlusion restoration, and facial function. Nationally, procedures for mandibular fractures generate notable surgical, anesthesia, and post-operative care utilization and intersect with trauma, oral and maxillofacial, and otolaryngology services.
Key payers referenced 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 common billing considerations. The publication highlights payer coverage patterns and reimbursement benchmarks where available, outlines common coding and billing themes associated with mandibular fracture repair, and summarizes policy and documentation elements that affect claims processing and audit risk. Clinical implications related to surgical setting, post-operative care, and coordination with dental fixation techniques are discussed to provide a comprehensive view for billing, compliance, and clinical teams. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 21453 describes surgical treatment of a mandibular (lower jaw) fracture using intraoral fixation that secures the fracture by attaching a device to the teeth. This procedure addresses fractures of the mandible resulting from blunt force trauma to the face.
-
Service type: Surgical fracture repair with intraoral dental fixation
-
Typical site of service: Operating room or surgical suite, often within an ambulatory surgical center or hospital setting

Clinical & Coding Specifications
Clinical Context
A 28-year-old male presents to the emergency department after an assault with blunt facial trauma. He reports malocclusion, pain, facial swelling, and numbness of the lower lip. Physical exam and maxillofacial CT demonstrate a displaced fracture of the mandibular body requiring operative stabilization. The patient is admitted and scheduled for open reduction and internal fixation with interdental fixation (arch bars) to stabilize the mandible during healing. The clinical workflow includes preoperative evaluation (history, airway assessment, imaging), informed consent, operating room anesthesia (general with nasoendotracheal intubation or oral with surgical interdental fixation timing), application of arch bars or interdental wiring to immobilize the fracture segments, intraoperative radiographic confirmation of reduction, postoperative monitoring in PACU, and short inpatient observation or discharge with outpatient follow-up for fixation removal and occlusal assessment.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the day of a procedure | Use when a distinct E/M visit is documented the same day as the operative procedure for preoperative evaluation or acute management separate from the procedure |
