Spouse seeking revision, do tricare cover this?????

I had the lap gastric done 7/2002. at my heighest I weighed 260, my lowest was 150, I got pregnant and gained 30 pounds. I lost about 20 or so...now 3 yrs after my son's birth Im at 197...thats 7 pounds over what I weighed at 9 months pregnant. and trying to look into having a revision. How was your journey towards a revision? I feel so bad that I have let myself down again. I have TriWest and located in Tacoma WA near Ft Lewis. Dr. Dewitt (a civilan dr) did my surgery in Alabama a couple of years before I got married and moved to CO, now we're in Washington (husband is active duty Army) I would like to have a revision...I want to find a local dr here and also see if my insurance will cover it. Any ideas anyone?
