Summary & Overview
CPT 21330: Reduction and Fixation of Complex Nasal Fracture
CPT code 21330 denotes surgical reduction and fixation of a complex nasal fracture performed through a nasal incision to restore airway function and cosmetic form. This procedure is clinically significant because nasal fractures can affect breathing, olfaction, and facial aesthetics; accurate reduction and secure fixation influence long-term outcomes and potential need for revision surgery. Nationally, charges and coverage policies for facial trauma surgery vary across private and public payers, making clarity on coding and site-of-service important for hospitals, surgeons, and payers.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication summarizes typical coverage considerations and site-of-service patterns for surgical repair of complex nasal fractures, while noting where payer-specific policies may differ.
Readers will find a concise clinical context for CPT code 21330, benchmarks and utilization patterns where available, and a summary of policy elements that commonly affect authorization and reimbursement for nasal fracture reduction with fixation. The content is organized to help clinicians, billing staff, and policy analysts understand coding intent, typical care settings, and the primary areas where payer rules and clinical practice intersect. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 21330 describes the reduction and fixation of a complex nasal fracture performed through a nasal incision. The procedure involves realigning displaced nasal bones to restore both nasal function and cosmetic appearance, with placement of a fixation device to maintain bone position during healing.
Service type: Surgical repair of complex nasal fracture
Typical site of service: Operating room or ambulatory surgical center, depending on clinical complexity and anesthesia requirements.
Data not available in the input for payers, associated taxonomies, and ICD-10 diagnoses.
Clinical & Coding Specifications
Clinical Context
A 28-year-old male presents to the emergency department after an altercation with midface trauma. He reports nasal obstruction, profuse epistaxis initially controlled with direct pressure, visible deformity of the nasal dorsum, and significant pain. Physical exam demonstrates a displaced, comminuted nasal bone fracture with septal deviation and instability on palpation. Imaging (facial radiographs or CT facial bones) confirms complex nasal fractures with bone fragments requiring open reduction and internal fixation. The patient is evaluated by an otolaryngologist (ENT) or facial/plastic surgeon and consented for operative repair.
In the operating room under general anesthesia, the surgeon makes a nasal incision, performs open reduction of the comminuted nasal fracture fragments, realigns the bones to restore nasal airway function and cosmetic contour, and applies internal fixation (for example, plates, screws, or other fixation devices) to maintain alignment during healing. Postoperative care includes nasal packing as needed, external splinting, analgesia, antibiotics per surgeon preference, and follow-up visits for wound and fixation assessment. Typical recovery includes activity restrictions and outpatient follow-up at 1 week, 4–6 weeks, and as clinically indicated for fixation removal if required.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the procedure required substantially greater work, time, or technical difficulty than typical. Documentation must support the increased services. |
23 | Unusual anesthesia | Use when general anesthesia was required for a procedure usually performed with local or no anesthesia. |
26 | Professional component | Use when reporting only the professional (physician) component separate from institutional technical services; rarely used for this full surgical service. |
50 | Bilateral procedure | Use when identical procedures are performed on both sides of the body and payer rules allow bilateral reporting; apply only if the fracture/fixation is bilateral. |
51 | Multiple procedures | Use when more than one distinct procedure is performed during the same operative session in addition to this code. |
52 | Reduced services | Use when the service was partially reduced or not completed as described by the full code. |
53 | Discontinued procedure | Use when the procedure was started but discontinued due to extenuating circumstances. |
59 | Distinct procedural service | Use to indicate a distinct procedure or service not ordinarily reported together, when applicable (ensure documentation supports distinctness). |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct operative components. |
78 | Unplanned return to OR for related procedure during postoperative period | Use when the patient returns to the operating room for a related procedure during the global period. |

Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
21330 | Open treatment of nasal bone fracture, including internal fixation as necessary; through external or intranasal incision | This is the primary procedure describing open reduction and fixation of complex nasal fractures. |
21320 | Closed treatment of nasal bone fracture; with manipulation, without fixation | Performed when reduction can be achieved without open approach or internal fixation; may occur prior to deciding open fixation. |
21315 | Closed treatment of nasal bone fracture; with manipulation requiring stabilization (e.g., splints) | Used when stabilization without internal fixation is adequate; may be an alternative to 21330. |
21420 | Open treatment of mandibular fracture; requiring internal fixation | May be performed concomitantly when additional facial fractures are present requiring fixation. |
