Zygomatic fracture, left side, init

This code signifies a fracture of the left zygoma (cheekbone) that is not open to the external environment. It indicates that the patient is receiving initial active treatment for this specific injury.

Use this code for a patient presenting with a newly diagnosed, non-compound fracture of the left zygoma. Documentation should clearly state "left zygomatic fracture," "closed," and that the patient is in the initial phase of care (e.g., emergency department visit, initial surgical repair).

• Confirm laterality (left) and fracture type (closed) are explicitly documented.
• Distinguish from open fractures (S02.40FB) and subsequent encounters for the same injury.
• Always sequence with an external cause code (V00-Y99) to describe the mechanism of injury.
