The surgeon I work for does Bariatric surgeries, normally he does not do the sleeve, however he went in the O.R. today to do a Roux-en-Y on a pt, and had to do a sleeve instead after he already started the sx. I don't know why yet but the nurse said it was medically nessessary. Does anyone know how to get the insurance company to give an auth # for the sleeve? All opinions are welcome. Thanks
