Anyone Switch BCBS ins plan to get coverage?

I found out at month 6 of my 7 month pre-op diet that my particular BCBS plan (AL) does not cover any bariatric surgery. Wow did I feel stupid for assuming it would.

After a little emotional breakdown, my husband and I started looking at options and found that his insurance plan BCBS (AL) does cover the band. So, things are pushed back while we wait for open enrollment with my new insurance going into effect in January.

My question is if anyone has ever done this, and what happened? I'm going to keep up my doctor's supervision so that I'll have had continual dr supervised diet well over the requirement. Do you guys think they'll make me start all over on the new plan? Have a waiting period? I'm just really curious and even though this may seem silly, I don't want to call BCBS because I'm irrationally afraid it will prompt them to change their policy if they know beforehand. Yes, that's so irrational, but I can't help it.
