Oth fracture of unsp great toe, subs for fx w nonunion

This code signifies a fracture of the great toe (hallux) that is not healing properly, specifically in an unspecified location within the great toe. It indicates that the patient is receiving ongoing care for this non-healing fracture.

Apply this code when a patient presents for follow-up care of a great toe fracture that has been diagnosed with nonunion. This would be used after the initial treatment phase, when the bone fragments have failed to unite and further intervention or monitoring is required.

• Ensure documentation clearly states "nonunion" for the great toe fracture.
• Verify this is a subsequent encounter, not the initial treatment.
• Confirm the specific great toe (left or right) is not documented; otherwise, a more specific code should be used.
