Displ trimalleol fx r low leg, 7thM

This code signifies a complex ankle fracture involving all three malleoli (medial, lateral, and posterior) of the right lower leg, where the bone fragments are not properly aligned. It specifically indicates that the initial injury was an open fracture (meaning the skin was broken), classified as Type I or II, and that the fracture has failed to heal after a previous treatment attempt.

Apply this code for follow-up encounters for a patient who previously sustained a right trimalleolar open fracture (Type I or II) and is now presenting with evidence of nonunion. This would be used when the patient is undergoing continued management, evaluation, or treatment for the unhealed fracture, such as considering revision surgery or prolonged immobilization.

• Ensure documentation clearly states "nonunion" and specifies the initial open fracture type (I or II).
• Verify laterality (right lower leg) is explicitly documented.
• This code is for subsequent encounters; an initial encounter would use a different code.
