Disp fx of lateral cuneiform of l ft, subs for fx w malunion

This code signifies a displaced fracture of the lateral cuneiform bone in the left foot that is currently healing with malunion. Malunion indicates that the bone has healed, but in an anatomically incorrect or misaligned position. This is a subsequent encounter, meaning the patient is receiving ongoing care for this previously diagnosed fracture.

Apply this code for follow-up encounters where a patient with a left lateral cuneiform fracture is being treated for malunion. This includes situations where the malunion is being monitored, or if interventions such as corrective osteotomy or other surgical revisions are being planned or performed to address the misalignment.

• Ensure documentation clearly specifies "displaced" and "malunion" for the left lateral cuneiform.
• Verify this is a "subsequent encounter" and not an initial treatment for the fracture.
• Do not use this code if the fracture is still in the active healing phase without malunion, or if it is a nonunion.
