Disp fx of unsp ulna styloid pro, 7thK

This code signifies a fracture of the styloid process of the ulna that has shifted from its normal anatomical position. The patient is in a subsequent phase of treatment, and the fracture, though initially closed, has failed to heal properly, indicating a nonunion.

Apply this code when documenting follow-up care for a patient with a previously diagnosed, displaced, closed fracture of the ulnar styloid process who is now presenting with evidence of nonunion. This would be used for encounters related to ongoing management, assessment, or intervention for the nonunion.

• Ensure documentation clearly states "nonunion" for a closed fracture in a subsequent encounter.
• Verify the fracture is specifically of the ulnar styloid process and not another part of the ulna.
• Do not use for initial encounters or for fractures that are healing normally.
