Disp fx of unsp ulna styloid process, init for clos fx

This code signifies a break in the styloid process of the ulna (the small, pointed projection at the end of the ulna bone near the wrist) where the bone fragments are no longer in their normal alignment. The fracture is closed, meaning the skin remains intact over the injury.

Apply this code for initial encounters with patients presenting with a newly diagnosed, displaced fracture of the ulnar styloid process. This is often seen following a fall onto an outstretched hand or direct trauma to the wrist.

• Ensure documentation specifies "displaced" and "closed" for accurate code assignment.
• Confirm this is the initial encounter for treatment of the fracture.
• Do not use if the specific side (left or right) of the ulna is documented; a more specific code would be appropriate.
