Displ Maisonneuve's fx unsp leg, 7thM

This code signifies a complex ankle injury involving a displaced fracture of the proximal fibula (Maisonneuve's fracture) along with associated ankle ligamentous disruption, specifically in an unspecified leg. The fracture is an open type I or II, meaning there is a wound communicating with the fracture site, and it has failed to heal properly, resulting in a nonunion. This encounter is for ongoing treatment of this persistent, unhealed open fracture.

Use this code for a patient presenting for follow-up care, surgical intervention, or other treatment related to a previously diagnosed Maisonneuve's fracture of an unspecified leg that was initially open (Type I or II) and has subsequently developed a nonunion. This applies when the patient is beyond the initial healing phase and the fracture has not united.

• Ensure documentation clearly specifies "unspecified leg" if laterality is not documented.
• Verify the fracture is explicitly documented as a Maisonneuve's fracture with associated nonunion and was initially an open fracture type I or II.
• This code is for subsequent encounters; an initial encounter for this specific condition would use a different code.
