Displ seg fx shaft of unsp fibula, 7thK

This code signifies a fracture involving a segment of the fibula's shaft that is no longer in its proper anatomical alignment. The injury is being addressed in a subsequent encounter, meaning the initial treatment has already occurred. Crucially, the fracture has failed to heal properly, indicating a nonunion.

Apply this code when a patient presents for follow-up care of a previously diagnosed fibular shaft fracture that is displaced and has developed a nonunion. This would include scenarios where surgical intervention for nonunion is being planned or has recently been performed, or during ongoing conservative management of a nonunion.

• Ensure documentation clearly states "nonunion" and "displaced" for the fibular shaft fracture.
• Verify this is a "subsequent encounter" and not the initial treatment for the fracture.
• Confirm the fibula is unspecified, as laterality (left/right) would require a more specific code.
