From what I know of insurance, they seem to want what they want. If they are asking for 3 more months, that's what they want. I had to do a 6 month diet. At first i was told that I didn't have to lose any weight, just participate. So I didn't lose any weight and then I was told that insurance would not be approved. So I had to do the diet again for 6 more months in order to get approved. This just happened on Thursday. What a nuisance insurance is. But, hey, you can try. They say nothing beats a try but a failure!!! Best of luck to you.
