Displ trimalleol fx r low leg, 7thR

This code describes a complex fracture of the right ankle involving all three malleoli (medial, lateral, and posterior) that is displaced. The patient is in a subsequent phase of care for an open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC) where the bone fragments have healed in an incorrect or deformed position.

Use this code when documenting follow-up care for a patient who previously sustained a displaced trimalleolar fracture of the right lower leg, and the initial open fracture was classified as type IIIA, IIIB, or IIIC. This code is appropriate when the fracture has healed, but with a noticeable malunion requiring ongoing management or evaluation.

• Ensure documentation specifies "subsequent encounter" and confirms the presence of malunion.
• Verify the original open fracture type (IIIA, IIIB, or IIIC) is clearly documented.
• Do not use for initial treatment or for nonunion; specific codes exist for those scenarios.
