Fracture of symphysis of mandible, init for clos fx

This code signifies a break in the bony fusion point at the front of the lower jaw, specifically a fracture of the mandibular symphysis. It indicates that the skin and soft tissue overlying the fracture site remain intact, and the patient is receiving initial treatment for this injury.

Use this code for patients presenting with a newly diagnosed, non-compound fracture of the mental protuberance or symphyseal region of the mandible. Documentation should clearly state "symphysis fracture," "closed fracture," and indicate that this is the initial encounter for treatment. This code is appropriate for emergency department visits, initial consultations, or hospital admissions for the primary management of this injury.

• Ensure documentation specifies "closed fracture" and "initial encounter" to support this specific code.
• Distinguish from other mandibular fracture sites (e.g., body, angle, ramus) which have different codes.
• If the fracture is open, a different code from the S02.66 series (e.g., S02.66BXA) would be appropriate.
