Disp fx of lateral malleolus of l fibula, 7thR

This code signifies a malunion of a previously sustained, displaced fracture of the lateral malleolus in the left fibula. The original injury was an open fracture, specifically classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. Malunion implies that the fracture has healed in an unsatisfactory position, leading to anatomical deformity or functional impairment.

This code is appropriate for encounters where a patient is being treated for complications arising from a malunited, open, displaced left lateral malleolus fracture. This includes follow-up visits for assessment, planning for corrective surgery, or management of ongoing symptoms related to the malunion. It should be used when the initial acute fracture treatment has concluded, and the focus is now on the healed but improperly aligned bone.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union."
• Verify the original fracture was indeed an open fracture type IIIA, IIIB, or IIIC.
• Confirm the laterality is left and the specific bone involved is the lateral malleolus of the fibula.
