Fracture of angle of mandible, unspecified side, 7thK

This code signifies a fracture located at the angle of the lower jaw, which has failed to heal properly (nonunion) and the patient is presenting for follow-up care or treatment related to this ongoing issue. The specific side of the mandible affected by the fracture is not documented or specified.

Apply this code when a patient with a previously diagnosed mandibular angle fracture presents for a subsequent visit, and imaging or clinical assessment confirms nonunion. Documentation should clearly state "nonunion" of the mandibular angle fracture and indicate that this is not the initial treatment encounter.

• Ensure documentation explicitly states "nonunion" and specifies the "angle of mandible."
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Do not use this code if the side (left or right) of the mandibular angle fracture is documented; instead, select a more specific code.
