Displ commnt fx shaft of unsp fibula, 7thM

This code signifies a complex injury involving a fibula fracture that has broken into multiple pieces and is no longer in its correct anatomical alignment. It specifically indicates that the patient is returning for care of this fracture, which was initially an open fracture (meaning the skin was broken) of either Type I or Type II severity, and the bone has failed to heal properly (nonunion).

Use this code for a patient presenting for follow-up treatment of a previously diagnosed open comminuted fibular shaft fracture (Type I or II) that has not united. This would apply to situations like a patient undergoing further surgical intervention, cast changes, or evaluation for persistent nonunion after initial treatment.

• Ensure documentation clearly specifies "comminuted" and "displaced" for the fibular shaft.
• Verify the original injury was an "open fracture type I or II" and that "nonunion" is explicitly stated.
• This code is for a "subsequent encounter," so it should not be used for the initial treatment of the fracture.
