Oth disp fx of lower end of l humer, subs for fx w malunion

This code signifies a fracture of the lower portion of the left humerus that was initially displaced but has since healed incorrectly, resulting in a malunion. This indicates a complication where the bone fragments have united in an abnormal position, potentially affecting arm function.

Use this code when documenting a patient's follow-up visit for a previously treated, displaced fracture of the distal left humerus that has healed with a noticeable deformity or angulation. This applies when the malunion is the primary focus of the encounter, such as for evaluation of ongoing symptoms or planning corrective surgery.

• Ensure documentation clearly states "left humerus," "lower end," "displaced," and "malunion" for accurate code selection.
• This code is for a subsequent encounter, so verify that the initial fracture treatment has already occurred.
• Consider additional codes for any associated pain, functional limitations, or planned surgical interventions related to the malunion.
