Fracture of mandible, unsp, subs for fx w nonunion

This code indicates a fracture of the lower jawbone that has not healed properly after an initial treatment, and the patient is presenting for follow-up care related to this nonunion. It specifies that the exact location of the mandibular fracture is not documented.

Use this code when a patient presents for ongoing management of a previously treated mandibular fracture that has failed to unite. Documentation should clearly state "nonunion" of the mandible and indicate a subsequent encounter for this condition, without specifying the exact fracture site.

• Ensure documentation explicitly states "nonunion" and "subsequent encounter."
• Do not use if the specific site of the mandibular fracture (e.g., condylar, symphysis) is known; instead, use a more specific code from the S02.6- series with the appropriate 7th character.
• This code is for the nonunion itself, not for initial treatment or routine follow-up of a healing fracture.
