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

This code signifies a non-displaced fracture of the hook of the hamate bone in the left wrist that is currently healing with malunion. Malunion indicates that the fracture has healed, but in an unsatisfactory position, potentially leading to functional impairment or pain.

This code is used for follow-up encounters where a previously diagnosed left hamate hook fracture is being managed, and imaging or clinical assessment confirms that the bone has healed in an abnormal alignment. This would apply to patients presenting with persistent symptoms or functional limitations due to the malunion.

• Ensure documentation clearly specifies "left wrist" and "nondisplaced" for the hamate hook fracture.
• The "P" seventh character indicates a subsequent encounter for a fracture with malunion, not initial treatment or routine healing.
• Verify that the physician's notes explicitly state or imply malunion, rather than nonunion or routine healing.
