Displaced unsp fx unsp great toe, subs for fx w nonunion

This code signifies a fracture of the great toe that is not healing properly, specifically in a subsequent encounter. The fracture's exact location within the great toe is not specified, and the bone fragments are out of alignment. This indicates a complication in the healing process requiring ongoing medical management.

Apply this code when a patient presents for follow-up care of a great toe fracture that has previously been diagnosed, and the physician documents nonunion. This is appropriate for encounters where the focus is on managing the delayed or failed healing of the fracture.

• Ensure documentation clearly states "nonunion" and that it's a subsequent encounter for the fracture.
• Verify the fracture is of the great toe; do not use for other toe fractures.
• Look for documentation of displacement, even if the specific site within the great toe is not detailed.
