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

This code signifies a fracture of the lunate bone in the right wrist that has become displaced, meaning the bone fragments are not properly aligned. Furthermore, the fracture has failed to heal adequately after an initial treatment, indicating a nonunion.

This code is appropriate for follow-up encounters where a patient is receiving ongoing treatment for a previously diagnosed and treated displaced right lunate fracture that has developed into a nonunion. This includes visits for cast changes, wound care, physical therapy, or surgical planning related to the nonunion.

• Always confirm laterality (right wrist) and the specific bone involved (lunate).
• Ensure documentation clearly states "nonunion" and that the fracture is displaced.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
