Disp fx of med cuneiform of unsp ft, subs for fx w malunion

This code signifies a displaced fracture of the medial cuneiform bone, located in the midfoot, that has previously been treated but is now experiencing malunion. Malunion indicates that the bone has healed in an incorrect or deformed position, which can lead to ongoing pain and functional impairment.

Apply this code when a patient presents for follow-up care of a medial cuneiform fracture that has healed improperly, resulting in a malunion. This would typically be used after initial treatment and when the malunion is being addressed, either conservatively or surgically.

• Ensure documentation clearly states "malunion" and specifies the medial cuneiform and "displaced" nature of the fracture.
• Verify the encounter is for subsequent care related to the fracture's healing complication, not an initial injury.
• Always check for laterality if specified in the clinical notes (e.g., right or left foot) and use the more specific code if available.
