Nondisp Maisonneuve's fx l leg, 7thR

This code signifies a nondisplaced Maisonneuve's fracture affecting the left leg, specifically when the patient is receiving follow-up care for a previously sustained open fracture classified as Type IIIA, IIIB, or IIIC, and has developed a malunion. A Maisonneuve's fracture involves a spiral fracture of the proximal fibula with an associated ankle injury, often including a deltoid ligament rupture and/or medial malleolus fracture. The malunion indicates that the bone has healed in an anatomically incorrect or misaligned position.

This code is appropriate for subsequent encounters where a patient with a documented nondisplaced Maisonneuve's fracture of the left leg is being treated for complications related to a prior severe open fracture (Type IIIA, IIIB, or IIIC) that has resulted in malunion. This would include scenarios such as evaluation for corrective surgery, physical therapy for functional limitations due to the malunion, or ongoing pain management. It should be used after the initial healing phase has concluded and the malunion has been identified.

• Ensure documentation clearly specifies "nondisplaced" and identifies the "left leg" for the Maisonneuve's fracture.
• Verify that the original open fracture was classified as Type IIIA, IIIB, or IIIC, and that malunion is explicitly documented.
• This code is for subsequent encounters; an initial encounter code would be used for the acute injury.
