Torus fx lower end of left tibia, subs for fx w nonunion

This code signifies a torus, or buckle, fracture affecting the lower portion of the left shin bone. It indicates that the patient is receiving ongoing care for this specific fracture, and unfortunately, the bone fragments have failed to unite properly.

Apply this code when a patient presents for follow-up treatment of a previously diagnosed torus fracture of the distal left tibia, and the physician documents nonunion of the fracture. This would be appropriate for subsequent office visits, cast changes, or evaluations for further intervention due to the persistent nonunion.

• Ensure documentation clearly states "nonunion" of the fracture.
• Verify the fracture location is specifically the "lower end" or "distal" tibia and on the "left" side.
• This code is for subsequent encounters, not the initial treatment of the fracture.
