Nicki, Cathy is right that a good place to start with this appeal is with Don Mills at Inamed. You can reach him at

The other thing you should do now is find your plan documents--your insurance plan paperwork, the certificate, the booklet, whatever you want to call it--and find the carrier's appeal procedures. The letter you received probably gives you a thumbnail of how to appeal, but you should also find out the big picture. How many times will they entertain internal appeals? Is there any provision for third-party intervention?
If there's any way you can find out, see if you can discover how long after FDA approval other types of procedures have been taken off the "investigational" list. That's the sort of thing that is slow to come, and carriers are under no pressure to move it along. Just because the FDA says it's an accepted procedure, your carrier is not obligated to agree. And their opinion that it's still investigational is going to be a company-wide opinion, so it's very unlikely that any internal review is going to change that.
So contact your state's department of insurance. (I'm sure they'll have a website where you can find this information.) See if they offer a review process for HMO decisions. Start researching what that is and how you'd have to proceed there. Here in NJ I had to exhaust my carrier's internal appeals before taking my case to an external review, but your state may be different.
The good news is that they did not deny your request saying you do not qualify for WLS. So whether it's via appeal of through the passage of time, eventually they will be paying for your weight-loss surgery, assuming it's still medically necessary.
You have to decide whether you're willing to fight and/or wait for the band, or go with their current favorite method, bypass. I was willing to fight AND wait, if necessary. There was no way I'd consider the bypass so all of my correspondence included the fact that for me it was either this surgery or no surgery. I gave reasons. And since everyone agreed that WLS was medically necessary for me--which no one had ever disputed--I was going without medically necessary treatment based on their arbitrary decision. That's not the kind of thing an external review board likes to see.
