Displ trimalleol fx l low leg, 7thQ

This code signifies a complex ankle fracture involving all three malleoli (medial, lateral, and posterior) of the left lower leg, where the bone fragments are not properly aligned. It specifically indicates that the initial injury was an open fracture (Type I or II) and that the bone has healed in an unsatisfactory position during a subsequent encounter.

Use this code when documenting follow-up care for a patient who previously sustained an open trimalleolar fracture of the left ankle, and imaging or clinical assessment confirms malunion. This applies to situations where the patient is presenting for ongoing management, evaluation of the malunion, or planning for corrective procedures.

• Ensure documentation clearly specifies "left" lower leg and "trimalleolar" involvement.
• Verify the initial fracture was an "open" type I or II and that "malunion" is explicitly stated or clearly implied.
• This code is for subsequent encounters; an initial encounter for the malunion would use a different code.
