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

This code signifies a fracture of the styloid process of the right ulna that is no longer in its anatomical position. The patient is in a later phase of treatment for this injury, and the fracture has failed to heal properly without surgical intervention.

Apply this code when documenting follow-up care for a patient with a previously diagnosed displaced right ulnar styloid fracture that is not uniting. This typically occurs after initial treatment, such as casting or splinting, has proven unsuccessful in achieving bone fusion.

• Ensure documentation explicitly states "nonunion" for the closed fracture.
• Verify the laterality (right) and specific bone (ulna styloid process) are clearly documented.
• This code is for subsequent encounters, not the initial treatment of the fracture.
