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

This code signifies a fracture of the medial cuneiform bone in the left foot that was initially nondisplaced, but has subsequently healed improperly, resulting in a malunion. The malunion indicates that the bone fragments have united in an anatomically incorrect position, potentially leading to functional impairment or pain. This diagnosis is made during a follow-up visit after the initial injury and treatment.

This code is appropriate for documenting a patient's visit where a previously diagnosed nondisplaced medial cuneiform fracture of the left foot is now confirmed to have healed with a malunion. This would typically be used during a follow-up appointment where imaging (e.g., X-ray) reveals the improper alignment of the healed fracture. It is also applicable when a patient presents with new or persistent symptoms related to the malunion of the previously treated fracture.

• Ensure documentation clearly states "malunion" and specifies the left foot and medial cuneiform.
• Verify that the initial fracture was indeed nondisplaced; if displaced, a different code would be appropriate for the initial injury.
• This code is for a "subsequent encounter," meaning it's used after the initial treatment phase for the fracture.
