What do you code in the case where the surgeon plans to do a laparoscopic biliopancreatic diversion with duodenal switch in two stages? some insurance companies do not cover the sleeve gastrectomy, which is the first part of this procedure. Also, I don't know of the BPD/DS to have a code if done laparoscopically. Need help with this scenario. What if the procedure is planned for being done at one session, laparoscopically and then the doc cannot complete it? Would you use just the sleeve code and not get paid or use the BPD/DS and add a modifier?
