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

This code describes a situation where a patient has a fracture of the lunate bone in their right wrist that was initially displaced, and during a subsequent encounter, the fracture is healing incorrectly, resulting in a malunion. Malunion indicates that the bone fragments have united in an anatomically incorrect or deformed position.

This code is appropriate for follow-up visits where a previously diagnosed right lunate fracture, initially displaced, is now complicated by malunion. It should be used when the patient is receiving ongoing care for the fracture's healing process, specifically addressing the malunion.

• Ensure documentation clearly specifies "right wrist" and "lunate" bone.
• Verify that the encounter is "subsequent" and that "malunion" is explicitly documented as the healing complication.
• Do not use this code for initial fracture treatment or for nonunion, which is a different healing complication.
