Disp fx of shaft of 4th MC bone, l hand, 7thP

This code signifies a fracture of the shaft of the fourth metacarpal bone in the left hand that has healed improperly, resulting in a malunion. The fracture was displaced at the time of injury, and this encounter is for ongoing management of the malunion.

Use this code for follow-up visits where a patient is being treated for a previously displaced left fourth metacarpal shaft fracture that has healed in an anatomically incorrect position. This would include scenarios where the malunion is being evaluated for potential corrective surgery or conservative management.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed healing."
• Verify the laterality (left hand) and the specific bone (fourth metacarpal shaft).
• Confirm this is a "subsequent encounter" for the fracture, indicating ongoing care after the initial treatment.
