Nondisp Maisonneuve's fx unsp leg, 7thM

This code signifies a non-displaced fracture of the fibula, specifically a Maisonneuve's fracture, where the exact leg (left or right) is not documented. It indicates that the patient is in a later stage of care for this injury, and the fracture was initially an open fracture (Type I or II) that has failed to heal properly, resulting in a nonunion.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed Maisonneuve's fracture, initially open, presents with evidence of nonunion. It should be used when the medical record does not specify which leg was affected. This code would be applicable during ongoing treatment for the nonunion, such as preparing for revision surgery or monitoring conservative management.

• Ensure documentation clearly states "nonunion" and that the initial fracture was an "open fracture type I or II."
• Only use this code when the laterality of the leg is truly unspecified in the medical record.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
