Here's a summary of what I've learned:
1. BC/BS IL's medical policy does not cover DS for BMI <50. (confirmed fact)
2. BC/BS IL's medical policy does not cover a 2 phased approach (i.e., sleeve now, switch later) - unless during the DS procedure there is medical reason to STOP. (confirmed fact)
3. I went, as requested by the bariatric coordinator, to the 2nd seminar with Dr. Kane (the son of the guy who is the namesake of the Kane Center). He is (allegedly) the doc in the practice who does the DS most often. Overall, his presentation was a little more scientific than the other guy (Rantis, the one my endocrinologist recommended) - but he sang the same tune as both Rantis and Guske....recommended 2 phased approach; DS only for BMI >50...blah blah. I met with the bariatric coordinator face to face while there, telling her i was still doing research and was leaning towards the DS. She repeated that my insurance does not cover DS for BMI <50, and suggested I consider the RNY if I didn't want the sleeve. I told her I wanted to pay cash for the DS (as a test - I don't have that kind of cash laying around) - and she said the hospital wouldn't allow payment out of pocket for a surgery not covered by insurance. (not sure whether that is actually true or not - because I'm fairly certain I don't trust this practice anyhow so it doesn't matter).
4. Meanwhile, their office sent me a package of info for their bariatric program, indicating I have been preapproved/authorized by insurance for a sleeve gastrectomy (do they not listen? but i guess - it's good to start with being approved for SOMETHING). (spoiler alert: even if I can't get approved for DS, I won't be having a sleeve gastrectomy with them)
5. I called Dr. Alverdy down at U of C. Jeremy the phone-answerer was not nice. Gave him my info, BMI, weight, height, comorbidities (he also asked if I could walk, or if I needed a wheelchair, cane or walker - which was new)....he said their bariatric coordinator would call me back within 4-5 business days if I'm eligible so I can sign up for another "seminar". I explained that I've already been to two, and understand the various weight loss procedures so well I might could deliver a seminar on the topic myself - and that I really didn't want to have to sit through yet another seminar. He said it would be up to the coordinator. And so - now I'm waiting again.
