Zygomatic fracture, right side, 7thK

This code signifies a fracture of the zygoma (cheekbone) on the right side that has failed to heal properly, indicating a nonunion. The patient is receiving active treatment for the nonunion of this previously sustained fracture.

Apply this code when a patient presents for ongoing management or treatment of a right zygomatic fracture that has been diagnosed as a nonunion. Documentation should clearly state "nonunion" of the right zygoma and indicate that the encounter is for active treatment of this complication.

• Requires a seventh character "K" for subsequent encounter for fracture with nonunion.
• Distinguish from malunion (seventh character "P") or routine follow-up of a healing fracture (seventh character "D").
• Always sequence this code first if the nonunion is the primary reason for the encounter.
