Fracture of tooth (traumatic), subs for fx w nonunion

This code describes a tooth fracture resulting from trauma that has failed to heal properly after initial treatment. Nonunion indicates that the fractured tooth segments have not fused or united, leading to persistent instability or symptoms. This condition typically requires further intervention due to the lack of successful healing.

Use this code for follow-up encounters where a previously treated traumatic tooth fracture is documented as having nonunion. This applies when the patient presents for ongoing management, evaluation, or treatment of the unhealed fracture. Documentation should clearly state "nonunion" or similar terminology indicating a failure of the fracture to heal.

• Ensure documentation explicitly states "nonunion" of the traumatic tooth fracture; mere delayed healing may not qualify.
• This code is for subsequent encounters; an initial encounter for a traumatic tooth fracture would use a code from the S02.5XXA category.
• Always sequence this code as the primary diagnosis if the nonunion is the reason for the encounter.
