Displ trimalleol fx unsp lower leg, init for opn fx type I/2

This code signifies a severe ankle fracture involving all three malleoli (medial, lateral, and posterior) that is visibly out of alignment. It specifically indicates an open fracture where the skin is broken, but the wound is relatively clean with minimal soft tissue damage, classified as Gustilo-Anderson Type I or II.

Apply this code for initial treatment of a trimalleolar fracture where the bone fragments are displaced and there is an open wound communicating with the fracture site. This is appropriate for cases presenting to the emergency department or for the first surgical intervention.

• Confirm documentation specifies displacement and involvement of all three malleoli.
• Ensure the open fracture is explicitly classified as Gustilo-Anderson Type I or II.
• This code is for the initial encounter; subsequent care will require different encounter codes.
