Displ Maisonneuve's fx l leg, 7thN

This code describes a specific type of ankle fracture involving a spiral fracture of the proximal fibula with an associated ankle injury (Maisonneuve's fracture) in the left leg. It indicates that the fracture fragments are not properly aligned and that the injury is an open fracture (skin broken) of a severe type (IIIA, IIIB, or IIIC). Furthermore, the fracture has failed to heal after an initial treatment, requiring further intervention.

Use this code for a patient presenting for ongoing management of a left Maisonneuve's fracture that was initially treated but has not united. This applies when the fracture was an open injury with significant soft tissue damage, and the patient is now in a subsequent phase of care for the nonunion. This code would be appropriate for follow-up visits, surgical planning for revision, or ongoing conservative management of the nonunion.

• Ensure documentation clearly specifies "left leg" and "Maisonneuve's fracture."
• Verify the open fracture type (IIIA, IIIB, or IIIC) is explicitly stated and that nonunion is confirmed.
• This code is for a subsequent encounter; an initial encounter for this specific injury would use a different code.
