Nondisp fx of unsp ulna styloid pro, 7thR

This code describes a situation where a patient has a previously treated, nondisplaced fracture of the ulna styloid process that was initially an open fracture of type IIIA, IIIB, or IIIC, and has now healed incorrectly (malunion). This indicates a follow-up visit for the ongoing management of this complicated healing outcome.

This code is appropriate for subsequent encounters when a patient presents with a malunion following an open fracture (Type IIIA, IIIB, or IIIC) of the ulna styloid process that was initially nondisplaced. It would be used for visits related to assessing the malunion, planning corrective surgery, or managing symptoms arising from the malunion.

• Ensure documentation clearly specifies "malunion" and the initial fracture type was open (IIIA, IIIB, or IIIC).
• Verify the encounter is "subsequent" and not for initial treatment or routine healing without complication.
• This code requires a seventh character "R" for subsequent encounter with malunion.
