Nondisp fx of lateral malleolus of r fibula, 7thK

This code signifies a fracture of the outer ankle bone of the right lower leg that has not shifted from its original position, and the bone fragments have failed to heal together after an initial treatment. This indicates a complication in the healing process of a previously treated closed fracture.

This code is appropriate for follow-up encounters where a patient is being treated for a right lateral malleolus fracture that was initially closed, but imaging or clinical assessment confirms nonunion. It applies when the fracture fragments remain in their anatomical alignment despite the lack of healing.

• Ensure documentation clearly states "nonunion" and specifies the "right lateral malleolus."
• Verify the fracture was initially "closed" and is still "nondisplaced" at the time of this subsequent encounter.
• Distinguish from malunion (improper healing) or delayed union (slow healing).
