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

This code signifies a fracture of the medial cuneiform bone in the left foot that has healed improperly, resulting in a malunion. The fracture was initially displaced, meaning the bone fragments were not in their normal alignment. This code is used when the patient is receiving follow-up care for this specific complication.

This code is appropriate for encounters where a patient is being treated for complications arising from a previously sustained and now malunited displaced fracture of the left medial cuneiform. This includes visits for assessment, management of pain or functional limitations due to the malunion, or planning for corrective procedures. It should be used after the initial healing phase has concluded and the malunion has been identified.

• Always ensure documentation clearly specifies "left foot" and "medial cuneiform."
• Verify that the encounter is for a "subsequent encounter" and that "malunion" is explicitly documented.
• Do not use this code for initial fracture treatment or for nonunion, which is a distinct complication.
