Nondisp fx of unsp radial styloid pro, 7thN

This code signifies a nondisplaced fracture of the radial styloid process that was initially an open fracture of a severe type (IIIA, IIIB, or IIIC) and is now experiencing nonunion. Nonunion indicates that the bone fragments have failed to heal together after a significant period.

Use this code for follow-up encounters when a patient with a previously treated severe open radial styloid fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC) is presenting with evidence of nonunion. This applies when the fracture itself remains nondisplaced at the time of the current encounter.

• Ensure documentation clearly specifies "nondisplaced" for the current encounter and "nonunion" as the healing complication.
• Verify the original injury was classified as an open fracture type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter would use a different code.
