Mine was just a last check to make sure I had completed all of the preoperative requirements, but I have Kaiser. They do things strange.
Mine was also a last check to make sure all my requirements had been completed. They also wanted new blood work so I could just hand in the report when I showed up for surgery. The surgeon just went over the procedure again and made sure I didn't have any unanswered questions. Good luck to you.
