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

This code signifies a buckle or torus fracture affecting the lower part of the tibia, where the bone has compressed or buckled without a complete break. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "malunion" specifies that the bone has healed in an incorrect or deformed position.

This code is appropriate for follow-up visits where a patient is being treated for a previously diagnosed torus fracture of the distal tibia that has healed improperly. This could include evaluations for pain, limited range of motion, or other complications arising from the malunion, or planning for corrective procedures.

• Ensure documentation clearly specifies "malunion" for the subsequent encounter.
• Verify the fracture location is the lower end of the tibia; other tibial fracture locations have different codes.
• Do not use for initial treatment or for nonunion, which is a separate complication.
