I had a huge issue with my insurance company when I applied for approval, and my surgeon's office genuinely did not know that the insurance company's policy changed. My insurance is funded through my employer, and I have one insurance type for primary care and another for hospitalization. My primary care insurance and hospitalization conflicted on their bariatric policy, and the hospitalization policy ended up controlling with a longer pre-op period.
My hospitalization insurance's policy changed on bariatric surgery recently. I would definitely look up the policy online for your insurance company and call to confirm what the requirements are. On the off chance your surgeon's office is wrong about anything you'll end up getting denied. While I was doing my research on the insurance company and figuring out the requirements I made the appointments a month apart for the 6-month evaluation anyway to cover my bases.
I know this is an extremely frustrating experience to get approval, but hang in there! It's 100% worth it.
