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

This code signifies a previous fracture of the hook-shaped projection of the hamate bone in the right wrist that has healed improperly, resulting in a deformity or functional impairment. The patient is currently receiving care for this complication of the original fracture.

Apply this code when a patient presents for treatment of a right hamate hook fracture that has healed in a misaligned position. This includes scenarios such as follow-up appointments for ongoing management of the malunion, surgical intervention to correct the malunion, or physical therapy addressing the resulting functional deficits.

• Ensure documentation clearly states "malunion" and specifies the right wrist.
• Verify that this is a subsequent encounter for the fracture, not the initial treatment.
• Do not use this code for nonunion or delayed union; specific codes exist for those conditions.
