Medicare is coving the sleeve if you have liver failure or a serious liver problem. Your doctor must call the provider line and get a direct acess to the contractor with your situation only the contractor can approve and process your claim, if you lose you can appeal to a administration law judge, go for it girl. I like it best also hate the lap band and the bypass, well it a trade off for different sickness. I understand also that medicare advantage might cover it now also that is medicare C, check before you change as there are over 200 plans.
