Disp fx of hook process of hamate bone, unsp wrist, init

This code signifies a break in the hook-shaped projection of the hamate bone, a carpal bone located in the wrist, where the bone fragments are no longer in their normal anatomical alignment. The injury affects an unspecified wrist and is being treated for the first time, with the skin remaining intact over the fracture site.

Apply this code for patients presenting with a newly diagnosed, displaced fracture of the hamate hook process following a traumatic event, such as a fall onto an outstretched hand or direct impact. This is appropriate when the specific wrist (left or right) is not documented, and the fracture has not yet received definitive treatment beyond initial assessment.

• Ensure documentation clearly states "displaced" and "closed fracture" for accurate assignment.
• Verify that this is the patient's initial encounter for this specific fracture; subsequent encounters will require a different seventh character.
• If the laterality (left or right wrist) is specified in the medical record, a more specific code should be chosen.
