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

This code signifies a torus (buckle) fracture located at the distal end of the humerus, where the bone has healed in an imperfect or misaligned position. It specifically indicates that the patient is presenting for follow-up care or treatment related to this malunion.

Apply this code when documentation confirms a previously diagnosed torus fracture of the lower humerus that has healed with malunion, and the current encounter is for ongoing management, evaluation, or treatment of this malunion. This could include assessment for corrective surgery, physical therapy, or monitoring of functional limitations.

• Ensure the documentation explicitly states "malunion" and specifies the lower end of the humerus.
• Verify that the encounter is for a subsequent visit related to the fracture, not the initial treatment.
• Do not use this code if the fracture is still acute or if the malunion is not explicitly documented.
