Displaced unsp fx left lesser toe(s), subs for fx w nonunion

This code signifies a left lesser toe fracture that was initially displaced but is now experiencing nonunion, meaning the bone fragments have failed to heal together after a period of time. It specifically indicates a subsequent encounter for the management of this nonunion.

Apply this code when a patient presents for follow-up care of a previously diagnosed displaced fracture of a lesser toe on the left foot, and the treating physician has documented that the fracture has not united. This is appropriate for ongoing treatment, evaluation, or surgical planning related to the nonunion.

• Ensure documentation clearly specifies "nonunion" and not delayed healing or malunion.
• Verify the laterality (left foot) and the specific toe(s) involved (lesser toe).
• Confirm the encounter is for subsequent care, not the initial treatment of the fracture.
