Need advice....

OK I have a week and a half before my final weigh in for my 6 month course. I am have no comorbidities and my start weigh was 258 so that puts me right at 40.4 bmi, my insurance requires bmi of 40 or above for no comorbidities so needless to say I have not gone under 258, I have actually gone up a couple of pounds. But I read my surg requirements and it says

"The BMI recorded on

the prior

authorization form should be based upon measu

rement of height and

weight within one month of requesting the evaluation."

My question is should I keep these few extra pounds on to get me to 41 bmi since they use the last measurement of the course or should I just try for my exact start weight. I don't want them to deny me because I didn't lose. But I really have not put anything on. Every weigh in I was within one pound of my start weight and I have printed my food journals and my DR says I have done very well. I think I am just starting to get loopy from constantly thinking about this approval. I was told when I started 'Just DO NOT drop below 40 bmi or they will for sure deny" I am hoping others have dealt with this situation, I know every ins is different, mine is Priority Health and I am in Michigan. I have not spoken to anyone with this ins and in my situation so I am really nervous.
