Hi, I have BCBS of TX and was banded yesterday. My understanding is that it's not necessarily wether the insurance company will cover the surgery, but wether or not you or (most likely) your employer chose to leave WLS off of the plan when it was purchased. My employer didn't have WLS coverage on my PPO plan so insurance wouldn't have covered me "no matter how necessary a doctor said it was" according to my advocate and doctor. Bottom line is, it all comes down to your coverage plan, not who your insurance carrier is. Think of it like car insurance- liability only vs full comprehensive plan. Hope that clears it up.
I plan to be off from work until next Monday.
I hope you're able to move forward with your WLS plans, I think this will turn out to be one of the best life decisions I've made.
