Summary & Overview
CPT 21465: Open Repair of Mandibular Condyle Fracture
CPT code 21465 designates open surgical repair of a fracture of the mandibular condyle accessed via a skin incision. This procedure is a principal intervention for displaced condylar fractures of the lower jaw resulting from blunt facial trauma and is relevant to trauma, oral and maxillofacial, and plastic surgery practices nationwide. Accurate coding of 21465 affects claims adjudication, facility utilization, and trauma care pathways across payers.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical indications and typical settings, payer coverage patterns, commonly reported modifiers, and related coding considerations. The publication highlights national benchmarks for utilization and reimbursement patterns where available, summarizes recent policy or coverage updates affecting surgical facial trauma care, and explains clinical context that influences coding decisions, such as operative approach and site of service.
This summary provides clinicians, coding professionals, and policy analysts with the core information needed to understand what CPT code 21465 represents, how it is used in practice, and which payers and settings commonly encounter this procedure. Data not available in the input are noted where applicable.

-
Service type: Surgical repair (open reduction and internal fixation) of mandibular condylar fracture
-
Typical site of service: Operating room or ambulatory surgery center for facial trauma surgery
Clinical & Coding Specifications
Clinical Context
A 28-year-old male presents to the emergency department after a motor vehicle collision with facial pain, malocclusion, and right preauricular swelling. Imaging (panoramic radiograph and CT maxillofacial) confirms a displaced fracture of the right mandibular condyle. The oral and maxillofacial surgery team plans open reduction and internal fixation (ORIF) of the mandibular condylar fracture with a preauricular skin incision under general anesthesia. Typical workflow: initial ED evaluation and airway assessment, radiographic imaging, operative consent and preoperative optimization, anesthesia induction, surgical access via skin incision to the condyle, reduction of the fracture fragments, fixation with plates/screws as indicated, irrigation and layered closure, postoperative maxillofacial splinting or intermaxillary fixation as needed, and inpatient or outpatient postoperative follow-up with radiographs and jaw function assessment.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased Procedural Services | Use when the procedure required substantially greater work than usual due to complexity, e.g., comminuted condylar fracture with extensive dissection. |
23 | Unusual Anesthesia |
