Zygomatic fracture, left side, 7thK

This code signifies a fracture of the left zygoma (cheekbone) that has failed to heal properly, and the patient is presenting for follow-up care related to this nonunion. Nonunion indicates that the bone ends have not united and healing has ceased. This typically involves ongoing management, assessment of healing progress, or planning for further intervention.

Apply this code when documentation clearly states a nonunion of a left zygomatic fracture and the patient encounter is for subsequent treatment or evaluation of this specific condition. This includes visits for monitoring, cast changes, wound care, or preparation for surgical correction of the nonunion. Documentation should explicitly mention "nonunion" and "subsequent encounter."

• Ensure the documentation specifies "nonunion" and not merely delayed healing or malunion.
• Verify the laterality is explicitly "left side" to avoid incorrect coding.
• This code requires an additional code for any associated external cause of the injury (e.g., V-Y codes for accidents).
