Disp fx of l radial styloid pro, subs for clos fx w nonunion

This code signifies a fracture of the styloid process of the left radius that is no longer in its anatomical position, and the bone fragments have failed to heal together after a previous treatment attempt. This indicates a complication where the fracture has not united, and the patient is presenting for further management of this ongoing issue.

This code is appropriate for follow-up encounters where a patient with a previously treated displaced left radial styloid fracture is diagnosed with nonunion. It should be used when the patient is receiving active treatment for the nonunion, such as surgical intervention, bone grafting, or continued conservative management aimed at achieving healing.

• Always sequence this code after the appropriate encounter code (e.g., Z47.89 for other orthopedic aftercare).
• Ensure documentation clearly states "nonunion" and specifies the left radial styloid process and its displaced nature.
• Do not use this code for initial fracture treatment or for malunion, which implies healing in an incorrect position.
