Disp fx of lateral malleolus of r fibula, 7thM

This code signifies a right ankle fracture involving the lateral malleolus, which is displaced from its normal anatomical position. It specifically indicates that the fracture was initially an open fracture (meaning the skin was broken) of either Type I or Type II severity, and it has subsequently failed to heal properly (nonunion).

Use this code for follow-up encounters where a patient is being treated for a previously diagnosed displaced open Type I or II fracture of the right lateral malleolus that has not united. This applies to situations where the nonunion is being managed, whether surgically or non-surgically.

• Ensure documentation clearly states "nonunion" for the right lateral malleolus fracture.
• Verify the original fracture was classified as an "open fracture type I or II."
• This is a "subsequent encounter" code, so it should not be used for the initial treatment of the fracture.
