Summary & Overview
CPT 21450: Open Repair of Mandibular Fracture
CPT code 21450 identifies open surgical repair of a mandibular (lower jaw) fracture caused by blunt facial trauma without manipulation. This code is clinically significant because mandibular fractures frequently require timely operative intervention to restore occlusion, facial structure, and function, and they carry implications for surgical resource use, anesthesia, and post-operative care across hospital and ambulatory surgical settings. Nationally, consistent coding supports accurate clinical documentation, reimbursement, and comparative utilization tracking for facial trauma care. Key payers analyzed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service, and a summary of payer landscape coverage. The publication also outlines relevant billing considerations, common modifiers seen with this service, and where to look for benchmark and policy updates. Data not included in the input—such as specific ICD-10 pairings, associated taxonomies, and related CPT codes—is explicitly noted as unavailable.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A typical patient is a 28-year-old male presenting to the emergency department after an assault with blunt facial trauma. He reports jaw pain, malocclusion, and difficulty opening his mouth. Imaging (panorex or facial CT) confirms a non-displaced or minimally displaced fracture of the mandibular body or ramus without need for closed manipulation. The patient is evaluated by an oral and maxillofacial surgeon in the ED or trauma service; decision is made for operative open reduction and internal fixation (ORIF) without manipulation under anesthesia because the fracture pattern requires direct exposure and fixation.
Preoperative workflow includes history and physical, informed consent, pre-op labs as indicated, anesthesia evaluation (general anesthesia), and surgical planning with fixation hardware prepared. Intraoperative documentation includes operative approach, exposure, fracture reduction, fixation method (plates/screws), estimated blood loss, and implants used. Postoperative workflow includes recovery in PACU, pain control, antibiotics as indicated, dietary instructions (soft/dietary modifications), follow-up visits with radiographic assessment, and documentation of healing and occlusion restoration.
