hi! I'm new too, I'm rounding up for a December surgery.
I do work for a insurance company, and the coverage ins and outs are pretty complex. I would leave it up to them, but here's another good idea to try.
Call the insurance provider, get a customer service specialist, and ask them a few good questions.
1. What is the criteria for a obesity/bariatric surgery coverage?
2. Are there any exclusions listed for or about obesity surgery, bariatric surgery, gastric sleeve, lap band, or surgeries assosicated with weight loss? (tricky words but use each one as a individual question - TRUST ME)
As they attempt to explain the criterias or exclusuions to you, write them down, and ask for further clarity on each one your unsure of.
Once you've made this list, see if it applies to you, but make the facts list 1st. With that being said, the other option is to see if your plan offers this policy online, Cigna does, and it allowed me to know what the criteria was up front.
Let me know if I can help clarify more; I've worked in the insurance industry for more than 8 years (if I dont know, I can find someone who does).
