Disp fx of body of hamate bone, right wrist, init for opn fx

This code signifies a break in the main part of the hamate bone in the right wrist, where the bone fragments are no longer in their normal anatomical alignment. This specific diagnosis indicates that the fracture has broken through the skin, exposing the bone to the external environment.

This code is appropriate for the initial treatment of an open, displaced fracture of the body of the right hamate bone. It should be used when the patient presents for the first time for this specific injury, and surgical intervention or initial wound care for the open fracture is being performed.

• Ensure documentation clearly specifies "displaced" and "open fracture" for the hamate body.
• Verify laterality (right wrist) is explicitly stated in the medical record.
• Confirm this is the initial encounter for this specific injury; subsequent care will require different encounter codes.
