Disp fx of lateral malleolus of unsp fibula, 7thP

This code signifies a fracture of the outer ankle bone (lateral malleolus) that has shifted out of its normal alignment. The fracture is in a healing phase, but the bone segments are joining together incorrectly (malunion), and the skin over the fracture is intact. This code is used for follow-up care after the initial treatment of the fracture.

This code is appropriate for documenting subsequent encounters for patients with a previously diagnosed closed lateral malleolus fracture that is now demonstrating signs of malunion. This includes follow-up appointments for monitoring the malunion, planning corrective surgery, or managing complications related to the improper healing.

• Ensure documentation clearly states "malunion" and that the fracture is "closed."
• Verify that this is a subsequent encounter, not the initial treatment of the fracture.
• Confirm the fracture location is specifically the lateral malleolus.
