Nondisp fx of med cuneiform of l ft, subs for fx w nonunion

This code describes a situation where the medial cuneiform bone in the left foot has a fracture that is not displaced, meaning the bone fragments are still in their normal alignment. The "nonunion" aspect indicates that the fracture has failed to heal completely after a typical healing period.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced medial cuneiform fracture of the left foot that has not united. This includes visits for ongoing management, evaluation of nonunion, or preparation for further intervention.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify the laterality (left foot) and the specific bone (medial cuneiform).
• Confirm this is a subsequent encounter, not the initial treatment of the fracture.
