Nondisp spiral fracture of shaft of ulna, unsp arm, init

This code signifies a fracture of the ulna bone in the forearm, characterized by a spiral break along the shaft without any significant displacement of the bone fragments. The specific arm affected is not documented, and this code is used for the initial treatment of a closed fracture, meaning the skin is intact.

Apply this code for patients presenting with a newly diagnosed spiral fracture of the ulnar shaft where the fracture fragments are still in good alignment. This is appropriate for the first encounter for definitive treatment, such as casting or splinting, when the laterality of the injury is not specified in the medical record.

• Ensure documentation clearly states "nondisplaced" and "spiral fracture of shaft of ulna."
• Only use this code for the initial encounter for treatment; subsequent care will require a different seventh character.
• If laterality (left or right arm) is documented, a more specific code should be selected.
