Nondisp transverse fx shaft of unsp rad, 7thR

This code describes a transverse fracture of the shaft of the radius that was initially an open fracture (Type IIIA, IIIB, or IIIC) but is now in a subsequent phase of healing with evidence of malunion. Malunion indicates that the fracture has healed, but in an unsatisfactory position, leading to anatomical or functional impairment.

Use this code for follow-up encounters where a patient is being treated for complications arising from a previously sustained open transverse radial shaft fracture, specifically when malunion has been diagnosed. This applies to situations where the initial injury was severe, involving significant soft tissue damage as classified by Gustilo-Anderson Type IIIA, IIIB, or IIIC.

• Ensure documentation clearly specifies "malunion" and the original fracture was an "open" transverse radial shaft fracture.
• Verify the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) of the initial open fracture is documented.
• This code is for subsequent encounters, not the initial treatment of the fracture.
