Displ trimalleol fx unsp low leg, 7thP

This code signifies a displaced fracture involving all three malleoli (medial, lateral, and posterior) of an unspecified lower leg, where the fracture has previously been treated but has healed in an imperfect or misaligned position. This malunion is being addressed during a follow-up visit for the closed fracture.

Apply this code for subsequent encounters when a patient presents with a documented trimalleolar fracture that has healed with malunion, and the fracture was initially closed. This is appropriate for follow-up appointments where the malunion is being monitored or further treatment for the malunion is being planned or performed.

• Ensure documentation clearly states "malunion" and specifies a "displaced trimalleolar fracture."
• Verify the encounter is "subsequent" and the initial fracture was "closed."
• Do not use this code for initial treatment or for nonunion; specific codes exist for those scenarios.
