Nondisp 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 injury to the deltoid ligament and/or medial malleolus, and disruption of the tibiofibular syndesmosis. In this instance, the fracture in the left leg is not displaced, and the patient is in a subsequent phase of care for a severe open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly.

This code is appropriate for documenting follow-up care for a patient with a previously diagnosed nondisplaced Maisonneuve's fracture of the left leg. It should be used when the initial injury was an open fracture of significant severity (Type IIIA, IIIB, or IIIC) and the bone has not united after the expected healing period. This indicates ongoing management for a complicated fracture.

• Ensure documentation clearly specifies "nondisplaced" and "left leg" for accurate laterality and displacement.
• Verify the original injury was classified as an open fracture Type IIIA, IIIB, or IIIC, and that nonunion is explicitly stated.
• This code is for subsequent encounters; an initial encounter for this specific nonunion would use a different code.
