Torus fx upper end of left radius, subs for fx w malunion

This code describes a specific type of incomplete fracture affecting the growth plate region at the top of the left radius bone, often seen in children. A torus fracture is characterized by buckling of the bone cortex rather than a complete break. In this case, the fracture has healed improperly, resulting in a malunion.

This code is appropriate for follow-up encounters where a previously diagnosed torus fracture of the upper left radius is being evaluated for a malunion. It indicates that the fracture has healed in an unsatisfactory anatomical position. This code would be used for ongoing management or assessment of the malunion.

• Ensure documentation clearly specifies "torus fracture" and "malunion" for the left radius.
• Verify that the encounter is subsequent to the initial treatment of the fracture.
• Distinguish from nonunion (failure to heal) or routine follow-up without malunion.
