Torus fx lower end of unsp ulna, subs for fx w malunion

This code signifies a torus, or buckle, fracture affecting the lower portion of the ulna bone, where the bone has compressed rather than fully broken. It specifically indicates that the patient is receiving care for complications related to this fracture, specifically malunion, meaning the bone has healed in an incorrect or deformed position.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed torus fracture of the distal ulna is being treated for malunion. This could include assessments, imaging, or discussions regarding corrective procedures for the improperly healed fracture. It should be used when the malunion is the primary focus of the current encounter.

• Ensure documentation clearly specifies "malunion" as the complication being addressed.
• Verify that the fracture is indeed a torus fracture and located at the lower end of the ulna.
• Confirm this is a subsequent encounter, not the initial treatment for the fracture.
