Displ trimalleol fx l low leg, 7thR

This code signifies a complex ankle fracture involving all three malleoli (medial, lateral, and posterior) on the left leg, which has healed improperly (malunion). It specifically indicates that the fracture was open, meaning the bone broke through the skin, and was classified as a severe open fracture type IIIA, IIIB, or IIIC. This code is used during the recovery phase after initial treatment.

Use this code when documenting follow-up care for a patient with a previously treated, displaced trimalleolar fracture of the left lower leg that has resulted in malunion. This applies to situations where the original injury was an open fracture of a severe type (IIIA, IIIB, or IIIC). This code would be appropriate for subsequent office visits, physical therapy, or surgical interventions addressing the malunion.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" for this specific fracture.
• Verify the original injury was an open trimalleolar fracture of the left lower leg, classified as type IIIA, IIIB, or IIIC.
• Do not use for initial treatment or for nonunion; a different code would be required for those scenarios.
