Unsp fx low end r tibia, 7thN

This code signifies a nonunion of an unspecified fracture located at the distal end of the right tibia, which was initially an open fracture classified as type IIIA, IIIB, or IIIC. Nonunion indicates that the bone has failed to heal completely after a prolonged period.

Use this code for follow-up encounters when a patient with a previously diagnosed open fracture (type IIIA, IIIB, or IIIC) of the lower right tibia is being treated for a confirmed nonunion. This applies to situations where the specific fracture pattern (e.g., transverse, oblique) of the distal tibia was not documented.

• Ensure documentation clearly states "nonunion" and specifies the right tibia and lower end.
• Verify the initial fracture was an open fracture classified as type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter code would be used for the acute injury.
