Displ trimalleol fx l low leg, 7thN

This code signifies a complex fracture involving all three malleoli (medial, lateral, and posterior) of the left lower leg, which is currently displaced. It specifically indicates that the fracture is an open fracture of severe type (IIIA, IIIB, or IIIC) and has failed to heal properly, resulting in a nonunion. This represents a subsequent encounter for ongoing management of this complicated injury.

Use this code when documenting follow-up care for a patient with a previously diagnosed displaced trimalleolar fracture of the left lower leg. The fracture must be an open fracture of type IIIA, IIIB, or IIIC, and the patient's current condition indicates a nonunion of the fracture fragments. This code is appropriate for encounters related to surgical intervention for nonunion, cast changes, or monitoring of the nonunion healing process.

• Ensure documentation clearly specifies "left" lower leg and "displaced" trimalleolar fracture.
• Verify the open fracture type (IIIA, IIIB, or IIIC) and the presence of nonunion are explicitly stated in the medical record.
• This code is for a subsequent encounter, meaning it's not for the initial treatment of the fracture.
