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

This code signifies a fracture of the lunate bone in an unspecified wrist that has become displaced, meaning the bone fragments are no longer properly aligned. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone is failing to heal properly.

Use this code for patients presenting for ongoing treatment of a previously diagnosed, displaced lunate fracture in an unspecified wrist that has not healed as expected. This applies to situations where surgical intervention, casting, or other therapies are being managed due to the nonunion.

• Ensure documentation clearly states "displaced" and "nonunion" for the lunate fracture.
• Verify the encounter is for subsequent care, not the initial injury.
• Confirm the wrist laterality is unspecified; otherwise, a more specific code should be used.
