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

This code signifies a fracture of the ulna bone in the forearm, specifically a spiral break in the shaft. The bone fragments are not in their normal alignment (displaced), and the injury location is not specified as left or right arm.

Apply this code for initial treatment of a closed ulnar shaft fracture where the fracture pattern is spiral and the fragments are displaced. This would be used when the documentation does not specify which arm is affected.

• Ensure documentation specifies "spiral" fracture and "displaced" for accurate code assignment.
• Confirm this is the patient's first encounter for this specific fracture.
• Do not use if the fracture is open, comminuted, or located in a different part of the ulna.
