Nondisp fx of unsp ulna styloid pro, 7thM

This code signifies a fracture of the styloid process of the ulna that has not shifted from its normal anatomical position. The injury is an open fracture, classified as Type I or II, and the patient is in a subsequent phase of care where the fracture has failed to heal properly.

This code is appropriate for documenting follow-up encounters for patients with an unhealed, non-displaced open ulna styloid fracture. It should be used when the initial treatment has not resulted in bone union, and the open wound was initially a Type I or II.

• Ensure documentation clearly specifies "nonunion" and the open fracture type (I or II).
• Verify the fracture is indeed of the ulna styloid process and is nondisplaced.
• This code is for subsequent encounters, not the initial treatment of the fracture.
