Disp fx of lateral malleolus of unsp fibula, 7thE

This code describes a fracture of the outer ankle bone (lateral malleolus) that is out of alignment, specifically when the skin was broken (open fracture type I or II) at the time of injury. This particular code is used during follow-up care when the fracture is healing as expected.

Apply this code for patients presenting for subsequent treatment of a displaced open lateral malleolus fracture (Type I or II) that is progressing through routine healing. This includes cast changes, follow-up X-rays showing callus formation, or physical therapy sessions during the healing phase. Do not use for initial treatment or for fractures with delayed or nonunion healing.

• Ensure documentation specifies "displaced" and "open fracture type I or II" for the initial injury.
• Confirm the encounter is for subsequent care and that healing is routine, not complicated.
• Verify the laterality of the fibula is unspecified in the medical record.
