Too much pre-op weight loss?

Originally I weighed 250 pounds and had a BMI of 41. In the reading I did about WLS, everything said I would need to loose weight before the surgery, so I've been working on that since the beginning of the year, and my BMI is now down to 38. The info I received at the WLS seminar shows my insurance, Aetna, requires 3 months of doctor supervised diet, exercise and counseling before they'll consider approval. My question is, if the 3 months of diet & exercise drops my BMI below 35 (another 25 pound weight loss would do that), will insurance then say I no longer qualify?? Would Dr. Edwards say I no longer qualify??
