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

This code describes a situation where a patient has a fracture in one or more of their lesser toes (any toe except the big toe) that is displaced, meaning the bone fragments are not properly aligned. Crucially, the fracture has failed to heal properly, resulting in a nonunion, and the patient is being seen for follow-up care related to this ongoing issue.

This code is appropriate for subsequent encounters when a patient is being managed for a previously diagnosed displaced lesser toe fracture that has developed a nonunion. This could include visits for monitoring, planning further interventions like surgery, or managing complications related to the nonunion. It signifies that the fracture is not healing as expected and requires continued medical attention.

• Ensure documentation clearly states "nonunion" for a displaced lesser toe fracture.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• If the specific lesser toe (e.g., second, third) is documented, a more specific code should be sought.
