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

This code signifies a fracture of the styloid process of the left ulna that is no longer in its anatomical position. The fracture is closed, meaning the skin is intact, and the bone fragments have failed to heal together after an initial treatment. This code is used for follow-up care related to this specific complication.

Apply this code when a patient presents for ongoing management of a previously diagnosed displaced closed fracture of the left ulnar styloid process, and the physician documents nonunion. This includes visits for evaluation, cast changes, physical therapy, or preparation for surgical intervention due to the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the left ulna styloid process.
• Verify the fracture is indeed displaced and closed; other codes exist for nondisplaced, open, or different anatomical locations.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
