Displ trimalleol fx unsp low leg, 7thJ

This code signifies a complex ankle fracture involving all three malleoli (medial, lateral, and posterior) that is displaced. It specifically indicates an open fracture, classified as Type IIIA, IIIB, or IIIC according to the Gustilo-Anderson classification, and is being treated during a subsequent encounter where delayed healing is observed.

This code is appropriate for follow-up visits or hospital admissions when a patient with a previously diagnosed and treated displaced trimalleolar open fracture (Gustilo-Anderson Type IIIA, IIIB, or IIIC) of an unspecified lower leg is experiencing a slower-than-expected healing process. It should be used after the initial active treatment phase.

• Ensure documentation clearly specifies "displaced trimalleolar fracture" and "open fracture type IIIA, IIIB, or IIIC."
• Verify that the encounter is for subsequent care and explicitly mentions delayed healing.
• Do not use this code for initial treatment or for fractures without documented delayed healing.
