Nondisp Maisonneuve's fx l leg, 7thM

This code describes a specific type of ankle fracture involving the proximal fibula and disruption of the tibiofibular syndesmosis, known as a Maisonneuve's fracture, in the left leg. The fracture fragments are not displaced, and the patient is in a subsequent phase of care for an open fracture (Type I or II) that has failed to heal properly (nonunion).

Use this code when documenting follow-up care for a patient with a previously diagnosed left Maisonneuve's fracture that was initially an open fracture. This code is appropriate when the fracture has not united and the patient is receiving ongoing treatment for this complication. It is specifically for non-displaced fractures.

• Ensure documentation clearly specifies "left leg" and "nondisplaced" for the Maisonneuve's fracture.
• Verify that the initial injury was an "open fracture type I or II" and that "nonunion" is explicitly stated in the medical record.
• This code is for subsequent encounters; an initial encounter for this specific scenario would use a different code.
