Disp fx of lateral malleolus of unsp fibula, 7thG

This code signifies a fracture of the outer ankle bone (lateral malleolus) that is no longer in its proper alignment, and the patient is presenting for follow-up care. The fracture is closed, meaning the skin is intact, and it is healing slower than expected.

This code is appropriate for patients presenting for subsequent visits (e.g., cast changes, follow-up X-rays, physical therapy) for a previously diagnosed displaced closed lateral malleolus fracture that is exhibiting delayed union. It indicates that the healing process is prolonged but not yet a nonunion.

• Ensure documentation specifies "displaced" and "delayed healing" for a closed fracture.
• Confirm the encounter is "subsequent" and not an initial treatment for the fracture.
• Laterality (left or right fibula) is unspecified with this code; use a more specific code if known.
