The requirements that I had to do for Tricare for LapBand were; a nutritionist eval, a psych eval, a TSH level test (blood test to check thyroid), a H-Pylori test (blood test to check for stomach ulcers), and a letter from my PCM saying that I am cardio and pulmonary wise healthy for the surgery. I had no problem getting any of that and had it all done within 2 weeks. Here was the snag....I've been on Tricare Standard for a year and switched back to Prime (just effective Jan. 1) so that I wouldn't have much out-of-pocket for the surgery. I had all the letters and tests done under Standard so now I have to go on base to my new PCM, but just to get a letter about the cardio/pulmonary things. All my other tests and letters are acceptable. Tricare covers the band whether you are Prime or Standard, but since I switched in the "middle" they had to throw in a kink in my otherwise smooth process!
