Disp fx of hook pro of hamate bone, r wrist, init for opn fx

This code signifies a break in the hook-shaped projection of the hamate bone, located in the right wrist. The fracture is displaced, meaning the bone fragments are not properly aligned, and the injury involves an open wound exposing the bone.

Apply this code for a patient presenting with an acute, open, displaced fracture of the right hamate hook. This is appropriate for the initial treatment encounter, such as in an emergency department or during the first surgical repair.

• Confirm laterality (right wrist) and the specific bone (hamate hook).
• Verify documentation explicitly states "displaced" and "open fracture."
• Ensure this is the patient's initial encounter for this specific injury.
