Nondisp fx of lateral malleolus of l fibula, 7thR

This code signifies a previously sustained, non-displaced fracture of the outer ankle bone (lateral malleolus) of the left fibula that is now healing improperly (malunion). The original injury was an open fracture, meaning the skin was broken, and was classified as a severe type (IIIA, IIIB, or IIIC).

Use this code for follow-up encounters where a patient is being treated for complications related to a malunited, non-displaced left lateral malleolus fracture. This applies when the initial injury was a severe open fracture and the bone has healed in an anatomically incorrect position.

• Ensure documentation specifies "malunion" and the "subsequent encounter" for treatment of this complication.
• Verify the original fracture was an open type IIIA, IIIB, or IIIC to accurately assign this specific code.
• Confirm the fracture is of the left lateral malleolus and is non-displaced.
