Disp fx of med malleolus of unsp tibia, 7thK

This code signifies a fracture of the inner ankle bone (medial malleolus) where the bone fragments are no longer aligned, and the fracture has failed to heal properly after initial treatment. This specific code is used when the patient is receiving follow-up care for this unhealed, displaced fracture, and the skin over the fracture site remains intact.

Apply this code when a patient presents for ongoing management, such as cast changes, physical therapy, or surgical planning, for a previously diagnosed and treated closed medial malleolus fracture that has not united. It is appropriate for situations where the physician explicitly documents nonunion of a displaced medial malleolus fracture during a subsequent encounter.

• Ensure documentation clearly states "nonunion" and "displaced" for the medial malleolus.
• Confirm the encounter is for follow-up care, not the initial treatment of the fracture.
• Verify the fracture is documented as "closed" (skin intact) to avoid using an open fracture code.
