BMI
Insurance companies make their own rules. I had WLS twice--both times my BMI was about 45. My insurance wouldn't pay anything. had that wonderful exclusion clause.
Now, though, I'm pleased to report my BMI is 25.8 (dammit, i'm still considered overweight...argh.. sorry, just computed that and didn't realize that. i thought surely i was normal by now!) But this is surely better than being morbidly obese.
I will stop now to save a rant on insurance companies and the money that they'd save by supporting WLS as all the other problems would disappear (for me the short list of problems that resolved: sleep apnea, infertility, blood pressure, shortness of breath, leg/knee pain).
good luck with trying to get them to pay! hope it works!
