Displaced spiral fracture of shaft of ulna, left arm, init

This code signifies a fracture of the ulna's shaft, specifically a spiral type, where the bone fragments are no longer in their normal alignment. It affects the left arm and is being treated for the first time, with the skin over the fracture remaining intact.

Apply this code for patients presenting with a newly diagnosed, non-open spiral fracture of the left ulnar shaft that shows displacement on imaging. This is appropriate for the initial visit where definitive treatment, such as casting or surgical planning, is initiated.

• Ensure documentation clearly specifies "left arm" and "spiral" fracture type.
• Confirm the fracture is "displaced" and "closed" (no open wound).
• The "A" in the seventh character indicates an initial encounter for active treatment.
