Disp fx of hook pro of hamate bone, r wrs, 7thK

This code signifies a fracture of the hook-shaped projection of the hamate bone in the right wrist that has shifted from its normal anatomical position. Importantly, this specific code indicates that the fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

Apply this code when a patient with a previously diagnosed displaced right hamate hook fracture is seen for treatment or evaluation of a confirmed nonunion. This would include visits for conservative management of the nonunion, preparation for surgical intervention, or post-operative care following a procedure to address the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the "right" wrist.
• Verify the fracture is of the "hook process" of the hamate bone.
• This "K" seventh character indicates a subsequent encounter for a nonunion, not initial treatment or routine healing.
