Disp fx of lateral malleolus of r fibula, 7thR

This code signifies a right ankle fracture involving the lateral malleolus (the outer ankle bone, part of the fibula) that is no longer in its correct anatomical position. It specifically refers to a subsequent encounter for an open fracture (where the bone broke through the skin) classified as Type IIIA, IIIB, or IIIC, and has healed improperly, resulting in malunion.

Use this code when documenting follow-up care for a patient who previously sustained a severe open fracture of the right lateral malleolus, and imaging or clinical assessment confirms that the bone has healed in an abnormal alignment. This applies to ongoing treatment, monitoring, or management of the malunion, such as planning for corrective surgery or managing chronic pain.

• Ensure documentation clearly specifies "right" fibula and "lateral malleolus."
• Verify the original injury was an open fracture type IIIA, IIIB, or IIIC, and that malunion is explicitly documented.
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
