Displ trimalleol fx l low leg, subs for clos fx w delay heal

This code signifies a left lower leg fracture involving all three malleoli (medial, lateral, and posterior) that is displaced, meaning the bone fragments are not properly aligned. The "G" suffix indicates that the patient is in a subsequent phase of care for this closed fracture, and healing is progressing slower than expected.

Apply this code when documenting follow-up care for a patient with a previously diagnosed displaced trimalleolar fracture of the left lower leg. This is appropriate when the fracture has not yet fully united and the physician notes delayed healing, but the fracture remains closed (skin intact).

• Ensure documentation clearly specifies "left" lower leg and "displaced" trimalleolar fracture.
• The "G" suffix is crucial and indicates subsequent encounter with delayed healing for a closed fracture. Do not use for initial treatment or malunion/nonunion.
• Verify the fracture is indeed trimalleolar, involving the medial, lateral, and posterior malleoli, not just bimalleolar.
