Fracture of base of skull, left side, 7thB

This diagnosis code signifies a traumatic break in the bone forming the base of the skull, specifically on the left side, where the skin and underlying tissues have been compromised, exposing the fracture site. This type of fracture often involves significant force and can be associated with intracranial injuries.

Apply this code for a patient presenting with a newly diagnosed, open fracture of the left skull base. Documentation must clearly indicate the "open" nature of the fracture (e.g., laceration communicating with the fracture, exposed bone) and specify the left side of the skull base. This code is appropriate for the initial treatment phase of the injury.

• Ensure documentation explicitly states "left side" and "open fracture" to support this specific code.
• Do not use this code for closed fractures or fractures of other skull regions; refer to appropriate S02.1- codes.
• Always sequence this code first when it represents the primary reason for the encounter.
