Arosped

Hello I just happened to stumble upon this forum and found everyones input very helpful thank you. I live in Billings and have been looking into getting Lap Band. I have made my initial appointment with Dr. Martin in Great Falls for next month. I do have a question if anyone can answer it for me. Someone mentioned Triwest (Tricare) in a previous post. I have that insurance and did look online at what the circumstances are that they will cover this. I do qualify, but do I need to get some kind of referal from a doctor or get pre approval before I have a first appointment? I have not seen any other Dr. about anyhing pertaining to my weight really, I go to the Dr when I have to, yearly exam that sort of thing. Anyone who has info for me would be greatly appreciated. Thanks, Angela
