Nondisp fx of nk of 4th MC bone, r hand, 7thK

This code signifies a fracture of the neck of the fourth metacarpal bone in the right hand that is not displaced, meaning the bone fragments are still in their normal alignment. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone has failed to heal properly after a reasonable period.

Use this code for patients presenting for ongoing treatment of a previously diagnosed, non-displaced right fourth metacarpal neck fracture where imaging or clinical assessment confirms that the bone has not united. This would include scenarios such as continued immobilization, physical therapy, or surgical planning for nonunion.

• Ensure documentation clearly specifies "nonunion" for the fracture healing status.
• Verify the laterality (right hand) and the specific bone (fourth metacarpal neck).
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
