Displ trimalleol fx unsp low leg, 7thH

This code signifies a complex ankle fracture involving all three malleoli (medial, lateral, and posterior) that has also been displaced. It specifically indicates an open fracture (Type I or II) that is currently in a phase of delayed healing, meaning the bone is not mending at the expected rate.

This code is appropriate for follow-up encounters where a patient with a previously treated displaced trimalleolar open fracture is experiencing delayed union. It applies when the fracture is still open (Type I or II) and the physician documents that healing is not progressing as anticipated. Use this for subsequent visits focused on managing the delayed healing of this specific type of injury.

• Ensure documentation clearly specifies "delayed healing" for an open fracture.
• Verify the fracture is indeed trimalleolar and displaced, not just bimalleolar or undisplaced.
• Confirm the encounter is for follow-up care related to the healing process, not initial treatment or routine follow-up without healing complications.
