Robotic Prostatectomy Procedures

For those performing a robotic prostatectomy do you use the laproscopic prostatectomy CPT code 55866? Also, do you bill for a co-surgeon or an assistant surgeon for the console side surgeon and the patient side surgeon? It seems our MAC does not want to pay for a co-surgeon; however, we can not get a direct answer from them. We even called the Medical Director, who asked for us to fax a few reports......Now we are on pre-payment review for this procedure. We bill 55866,51800,38571.
I would appreciated ANY feedback.
Thanks.
