New to tricare, misc insurance ????'s

Hello all.:help:..I had a quick question about tricare compared to other insurance co's coverage for this procedure. I am enaged to a retired Navy man and will be covered with tricare after we are married. We live in kansas and will do all doctoring in Leavenworth. I currently do not have any type of insurance on just myself and was wondering if it would be worth it to just go to an outside company such as blue cross etc..and pay out of pocket premiums for myself or go ahead and get the tricare in hopes that one day they will cover this surgery. Also, is there anything I should be doing this early in the game to get prepared??? example, food journal for doc to go over, etc.I know I will have a new doc after I am on my husbands insurance, if I decide to be..I am not on any medications except for migraine meds, have never been on a medically supervised diet or have never been diagnosed with any weight issue diseases, at least not yet...I am just tired of the yo-yo dieting and am sure the heart, diabetic, BP issues are sure to come if they have not already. 9 ( have not been to a doc in years except for headaches and he just says to watch my fat grams regarding my weight, no guidance etc.....grrrrr)Thanks for any help and God Bless...
