Everybody has a difference requirement for there insurance company and/or surgeon team. Before I even meet my surgeon, I had a upper endoscopy, HIDA scan, gi nutrition e val, nut e valve, gi doc saying what I needed for surgery and his PA backing up his claim with a PLAN B, my pcp cleared me. The only things that I needed was a sleep study, 24 hr ph test, gastro empty stomach test, blood work, ultrasound, pulm doc clearence, ekg and physical with chest x ray. But, my surgeon team turn in all my paperwork before I had my 24 hr Ph test, ultrasound and sleep study and I was still approved by Cigna. Hope you get everything approve. I am not doing this for weight loss like everybody else on here... I am doing it to help my gastroparesis and GERD to go away. Sent from my SM-G973U using BariatricPal mobile app
