Nondisp fx of hook pro of hamate bone, unsp wrs, 7thP

This code signifies a fracture of the hook of the hamate bone in an unspecified wrist that is not displaced. The patient is in a subsequent phase of care, and the fracture is healing incorrectly, resulting in a malunion.

This code is appropriate for follow-up encounters where a previously diagnosed, non-displaced hamate hook fracture is showing signs of malunion. This would typically be documented by a physician after imaging studies confirm the improper healing.

• Ensure documentation clearly states "malunion" and not "nonunion" or "delayed healing" for accurate code selection.
• Verify the fracture is specifically of the "hook process" of the hamate.
• Confirm the encounter is for subsequent care, not initial treatment.
