Wow, that is terrible, seems the insurance companies would want you to have the surgery if you are morbidly obese since it will save them money in the long run. I have seen people have the surgery for vanity only reasons and can see if insurance wants to deny it for those reasons but Diabetes, and other comorbid reasons are reasons to have this surgery. Sadly, when and if Obamacare goes in, this operation may be something that will never be covered if you are on govt insurance but if private insurance(obamacare makes it mandatory to have insurance and private insurance will be what you get unless very poor) it will be up to the insurance company like now.
Sorry to hear you went through all that to get this necessary surgery. IT is now being touted by people like Dr Oz, so docs are getting lots of requests and some are not going to fit the rules that the insurance companies have at this time. I know Medicaid people in MA have to go for 6 mos of nutrition counseling and support groups etc in and effort to make sure they are committed and see if they can really lose with nutritional means instead of surgery. There are other insurances that require a 3 month period, some require mulitple clases to be attended and some just one of each and psych consult. It is not easy being obese for sure and then not easy to make the life changing decision to change all eating habits and lose weight due to restriction or malabsorption, NOT an easy decision! Pick your surgeon wisely, lots of surgeons will now get on the bandwagon once there are lots of people requesting it but there needs to be a team approach or the patients will lose in that transaction. Pick a doc who is very experienced, in the surgery and in the approval network.
