CPT® Code 22319

Open treatment and/or reduction of odontoid fracture(s) and or dislocation(s) (including os odontoideum), anterior approach, including placement of internal fixation; with grafting

The CPT® Code 22319 refers to the open treatment and/or reduction of odontoid fractures and/or dislocations, which may include the os odontoideum, through an anterior approach. This procedure involves the use of internal fixation to stabilize the fracture or dislocation. The odontoid process, which is a tooth-like projection from the axis (the second cervical vertebra), is critical for the stability and function of the cervical spine. During the procedure, the patient is positioned supine, allowing the surgeon to access the cervical spine effectively. An incision is made through the muscle layers while carefully avoiding critical structures such as the carotid artery, trachea, and esophagus. The surrounding soft tissues are retracted to provide a clear view of the surgical site, and any necessary vessels may be ligated to control bleeding. Guide wires are utilized to stabilize the fracture or dislocation, ensuring proper alignment. If bone grafting is required to promote healing and stability, this code is applicable. In contrast, if no grafting is necessary, the appropriate code would be 22318. Additionally, a drain may be placed to prevent fluid accumulation, and the surgical incisions are subsequently closed to complete the procedure.
