We make sure to get the WC info, adjusters name, etc. If there is attorney we also get an LOP. MOST likely since you are referencing witnesses, this is an open case and an attorney is involved (safe bet). Make sure to get the LOP. I do mental health and we see a lot of sexual harrassment go in as WC but patient's don't file it that way, in which case we tell them they are responsible for payment unless there is an open case.
