Displ Maisonneuve's fx l leg, 7thR

This code describes a Maisonneuve's fracture of the left leg, which involves a spiral fracture of the proximal fibula with an associated ankle injury, specifically a tear of the distal tibiofibular syndesmosis and often a medial malleolar fracture or deltoid ligament rupture. The fracture is displaced, meaning the bone fragments are not in their normal alignment, and has previously been treated but is now presenting with malunion, indicating improper healing. This specific code applies to an open fracture, classified as Type IIIA, IIIB, or IIIC, which signifies significant soft tissue damage and potential contamination.

Use this code for a patient presenting for follow-up care or treatment of a malunited Maisonneuve's fracture of the left leg, where the initial injury was an open fracture of a severe type (IIIA, IIIB, or IIIC). This code is appropriate when the malunion is the primary reason for the current encounter, such as for surgical correction of the malunion or ongoing management of its complications. It should be applied after the initial active treatment phase of the fracture.

• Always confirm the laterality (left leg) and the specific type of open fracture (IIIA, IIIB, or IIIC) from the medical record.
• Ensure documentation clearly states "malunion" as the reason for the subsequent encounter, rather than delayed healing or nonunion.
• Do not use this code for initial treatment or for subsequent encounters where the fracture is still undergoing routine healing without complications like malunion.
