Disp fx of lunate, left wrist, subs for fx w nonunion

This code signifies a fracture of the lunate bone in the left wrist that has shifted out of its normal alignment and has failed to heal properly. The "nonunion" indicates that the bone ends have not fused together after a significant period, despite treatment. This condition often leads to persistent pain, instability, and functional impairment of the wrist.

This code is appropriate for subsequent encounters when a patient with a previously diagnosed and treated displaced left lunate fracture presents with evidence of nonunion. This includes follow-up visits for ongoing management, evaluation of nonunion, or preparation for further intervention. It should be used after the initial treatment phase has concluded and the fracture has failed to unite.

• Always confirm the laterality (left wrist) and the specific bone involved (lunate).
• Ensure documentation clearly states "nonunion" and that the fracture was displaced.
• This "K" seventh character indicates a subsequent encounter for a fracture with nonunion; do not use for initial treatment or routine healing.
