Disp fx of 4th metatarsal bone, unsp ft, 7thP

This code signifies a previously treated fracture of the fourth metatarsal bone that has healed incorrectly, resulting in a malunion. The fracture was initially displaced, meaning the bone fragments were not in proper alignment. This code is used during the ongoing management of this specific complication.

Apply this code when a patient presents for follow-up care, evaluation, or treatment of a malunited fracture of the fourth metatarsal, where the initial injury involved displacement. This typically occurs after the initial healing phase, when the improper alignment becomes evident and requires further intervention or monitoring.

• Ensure documentation clearly states "malunion" and specifies the "fourth metatarsal" and "displaced" nature of the original fracture.
• Confirm this is a "subsequent encounter" for the fracture, not the initial treatment.
• Do not use if the malunion is related to a stress fracture or pathological fracture; specific codes exist for those scenarios.
