Disp fx of med cuneiform of l foot, subs for fx w nonunion

This code signifies a displaced fracture of the medial cuneiform bone in the left foot that has failed to heal properly, indicating a nonunion. It specifically applies to a patient who is receiving ongoing care for this unhealed fracture after the initial treatment.

Use this code for follow-up encounters where a patient is being managed for a previously diagnosed displaced medial cuneiform fracture of the left foot that has not united. This includes situations where surgical intervention for nonunion is being planned or has been performed, or conservative management for nonunion is ongoing.

• Ensure documentation clearly states "nonunion" and specifies the medial cuneiform of the left foot.
• Verify the fracture is explicitly described as "displaced."
• Confirm this is a subsequent encounter for the fracture, not the initial treatment.
