SLK248 I have Cigna and luckily for me I worked with a surgery group that has patient advocates. Their sole responisibility is to assist with whatever each individual's insurance companies requirements are and keep track of what you have.
For my Cigna plan, I needed 90 consecutuive days of a monitored nutritional regimen. The surgery group has these classes that that each insurance company has. I attended once per month and classes were lead by a nut. I completed my final class on 1/30. I have been approved as of 2/14 (HAPPY VALENTINE'S DAY TO ME!!!). It woexxcept it sat on someone's desk for a week and a half w/o any movement.
Don't feel pressured to "lose weight" in the 90 days. I actually gained weight. That timeframe is more for you to learn about what the lifestyle changes are going to be after your surgery. The preop diet is also not about losing weight, but more about cleansing your liver. You cannot have a fatty liver going into surgery. Therefore if you can began to try to implement a few lifestyle changes now, it will assist you going forward.
Now I am not saying do what I did. I should have been more disciplined during that time, but I am on track now. I am on my pre-op diet 1/30. I have lost 11lbs. I do not have my surgery date yet, but I should know by the end of the week.
Good luck.
