Please help! I have an operative report that three coders have come up with three different answers for. My physician's patient has an acute AC dislocation. The surgeon performed an open coracoclavicular reconstruction, using a tibialis allograft plus two screws and wiring for reconstruction. He excised 1 cm of the distal clavicle before attaching the graft. He called this a modified Weaver Dunn procedure. Any help appreciated. Thanks.
