Summary & Overview
CPT 21336: Reduction of Nasal Septum Fracture, Open Approach
CPT code 21336 identifies the surgical reduction or realignment of a fractured nasal septum via a nasal incision, a procedure aimed at restoring both airway function and cosmetic nasal contour. Nationally, this code is used across settings where facial trauma and septal deformity require operative management, and it intersects with trauma, otolaryngology, and facial plastic surgical care pathways. Clarity on coding and coverage is important for accurate claims adjudication and for aligning clinical documentation with procedural intent.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, typical sites of service, and the common modifiers associated with billing this code.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult who sustained facial trauma after a fall, assault, or sports injury and presents with nasal obstruction, septal deviation, epistaxis, or cosmetic deformity. Initial evaluation includes history, physical exam with anterior rhinoscopy and nasal endoscopy, and facial radiographs or CT if concern for complex facial fractures. Conservative measures (analgesia, nasal packing if bleeding) are applied emergently. Once acute swelling and bleeding are controlled, the patient returns for an operative procedure under general or local anesthesia. The surgeon performs a closed or limited open approach via a nasal incision to reduce and realign the fractured nasal septum, with placement of sutures or internal splints to stabilize the septum. Perioperative documentation includes indication, consent, anesthetic type, intraoperative findings (location and displacement of septal fracture), maneuvers performed to reduce the fracture, materials used (sutures, splints), estimated blood loss, and post-operative instructions. Typical site of service is the ambulatory surgical center or hospital outpatient department; in emergent settings the emergency department may stabilize prior to definitive reduction. Billing uses the procedure code 21336 for reduction of nasal septum fracture through a nasal incision to restore function and appearance.
