Disp fx of lunate, unsp wrist, init encntr for open fracture

This code signifies a break in the lunate bone, one of the carpal bones in the wrist, where the bone fragments are no longer in their normal alignment. This specific code indicates that the fracture is open, meaning there is a break in the skin exposing the bone, and it is the initial treatment for this injury.

Use this code for a patient presenting for the first time with a documented displaced open fracture of the lunate bone in an unspecified wrist. This would apply to emergency department visits, initial orthopedic consultations, or admissions for surgical repair of such an injury.

• Ensure documentation clearly states "displaced" and "open" for the lunate fracture.
• Confirm this is the initial encounter for treatment; subsequent care would use a different encounter character.
• If the specific wrist (left or right) is documented, a more specific code should be selected.
