Fracture of angle of right mandible, 7thK

This code signifies a fracture located at the angle of the right lower jawbone that has failed to heal properly after initial treatment. It indicates that the patient is presenting for follow-up care related to this persistent nonunion.

Apply this code when documentation clearly states a nonunion of a previously treated fracture of the right mandibular angle. This is appropriate for subsequent encounters where the patient is receiving ongoing management for the nonunion, such as further surgical intervention, bone grafting, or prolonged immobilization.

• Ensure documentation explicitly states "nonunion" and specifies the "right" mandible and "angle" location.
• This code requires a 7th character "K" for subsequent encounter with nonunion; do not use for initial treatment or routine healing.
• Consider sequencing this code with external cause codes (e.g., W00-Y38) if the cause of the original fracture is still relevant and documented.
