Summary & Overview
CPT 22319: Anterior Repair of Odontoid Fracture with Internal Fixation
CPT code 22319 represents anterior surgical repair of odontoid fractures or dislocations using internal fixation and bone grafting. Odontoid fractures are the most common cervical spine fractures and often follow traumatic neck injury; repair aims to restore cervical stability and protect spinal cord function. This code captures a definitive operative approach for C1–C2 junction injuries and has clinical and billing significance due to procedure complexity, variable site-of-service utilization, and implications for payer coverage and utilization management.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, expected service setting, common modifiers and coding considerations, and how this procedure is represented across major payers. The publication summarizes benchmark measures where available, notes common billing practices, and highlights policy elements relevant to authorization, inpatient versus outpatient designation, and documentation expectations for surgical fixation and bone grafting of the odontoid.
The content is intended for coding professionals, surgical providers, and revenue cycle staff seeking a practical national-level briefing on coding, site-of-service implications, and payer considerations for anterior odontoid repair with internal fixation and grafting.
Billing Code Overview
CPT code 22319 describes surgical repair of an odontoid fracture or dislocation using an anterior (front of neck) approach with internal fixation and bone grafting. The procedure addresses separation of the odontoid from the second cervical vertebra and is typically performed after traumatic injury to the upper cervical spine.
Service type: Open surgical repair with internal fixation and bone grafting
Typical site of service: Inpatient or outpatient hospital operating room
Clinical & Coding Specifications
Clinical Context
A 45-year-old male presents to the emergency department after a high-speed motor vehicle collision with neck pain, limited neck motion, and point tenderness at the upper cervical spine. Initial cervical CT demonstrates a displaced odontoid (dens) fracture of the axis (C2) with instability. The surgical team elects an anterior odontoid screw fixation with bone grafting to restore alignment and stability.
Preoperative workflow includes trauma evaluation, cervical spine CT and x-rays, neurosurgical consultation, informed consent emphasizing risks (infection, neurovascular injury, nonunion), crossmatch if indicated, and preoperative anesthesia assessment. Intraoperative workflow involves an anterior cervical approach in the operating room with fluoroscopic guidance, placement of one or more odontoid screws and autograft or allograft bone grafting for fusion, hemostasis, and incision closure. Postoperative management includes cervical immobilization, postoperative imaging to confirm hardware position, pain control, routine wound checks, and outpatient follow-up for fusion assessment and activity restrictions.
