Summary & Overview
CPT 21462: Open Repair of Mandibular Fracture with Intraoral Fixation
CPT code 21462 denotes open surgical repair of a mandible (lower jaw) fracture with intraoral fixation that secures the fracture to the teeth. This procedure is a key component of facial trauma management and carries implications for hospital resource use, surgical specialty coding, and post-operative care coordination. Nationally, procedures addressing mandibular fractures are performed across hospital operating rooms and ambulatory surgical centers by oral and maxillofacial surgeons, otolaryngologists, and trauma surgeons.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for CPT code 21462, benchmarks and utilization considerations where available, typical sites of service, and common coding adjacencies. The publication outlines billing and documentation themes relevant to trauma-related mandibular repair and highlights areas where policy updates or payer-specific coverage rules often affect claims processing and authorization.
This summary is intended to orient coding professionals, revenue cycle staff, and clinical leaders to the clinical procedure represented by CPT code 21462, what to expect in terms of service delivery, and the payer landscape that commonly covers this surgical intervention. Data not available in the input about specific modifiers, ICD-10 pairings, or associated taxonomies is noted for follow-up.
Billing Code Overview
CPT code 21462 describes surgical treatment of a mandibular fracture through an incision with application of an intraoral fixation device that secures the fracture to the teeth while the mandible heals. The procedure addresses fractures of the lower jaw caused by blunt facial trauma and involves open access to the fracture site and placement of dental-based fixation.
-
Service type: Surgical fracture repair (open reduction with intraoral fixation)
-
Typical site of service: Hospital operating room or ambulatory surgical center with oral and maxillofacial surgery capabilities
Clinical & Coding Specifications
Clinical Context
A 28-year-old male presents to the emergency department after an assault with direct blunt trauma to the lower face and jaw. Clinical assessment and maxillofacial CT confirm a displaced fracture of the mandible involving the body region with malocclusion and limited mouth opening. The patient is scheduled for open reduction and internal fixation using tooth-borne fixation (interdental splint or arch bars) placed through an intraoral incision to restore occlusion and stabilize the fracture. Preoperative workflow includes airway assessment, informed consent, anesthesia clearance, and dental occlusal planning. In the operating room under general anesthesia with orotracheal intubation, the surgeon makes an intraoral incision to access the fracture, reduces the segments, and applies a fixation device attached to the teeth to secure alignment while healing. Postoperative care includes pain control, antibiotics as indicated, oral hygiene instructions, soft diet, outpatient follow-up for wound and fixation assessment, and dental/occlusion evaluation for removal of fixation when healing is sufficient.
