Where to begin?
You've come to the right place! This board is a little slow though, so if you want some faster responses, people on the main message board or your state message board are a good help also. My name's Megan, I'll be 21 next month. I just had the surgery on Dec. 13th.
I'm glad that you've done your research! Have you shopped around for surgeons yet? Do you know what kind of surgery you want? What you want to first do is get ahold of your insurance company and find out if under your plan, they cover it and if they do cover it, which type of surgery they cover (Ex. ours only covers RNY, they don't cover lapband because they say it's still investigational). From there, ask them what things you need to do to be approved for surgery or where you can find that information (for example, for my insurance company, all the requirements are posted on their webpage). Some requirements are like seeing a psychologist, a nutritionist, getting the okay from your primary care doctor/physician, etc. Anyhow, once you have studied the different types of surgeries your insurance company will cover, find a surgeon that does that type of surgery who's in your insurance companies network, usually they'll only cover certain surgeons. Once you've found a surgeon, do as much research as you can on them, call their office and tell them you're interested in the surgery and request some information from them and see if there's any kind of information meeting you need or can go to and then they'll take you from there in the process.
That's kind of the gist of what you should do, or what I and people I know have done. You want to cover all your bases so you have better chance of approval. With a BMI of 49 I don't think you'll have any problems being approved though, unless there's an exclusion in your policy. Let us know how it goes! If you have any other questions, feel free to ask!! Hope this helps!!
