Recent approval with Cigna?

Anyone recently been approved for surgery with Cigna insurance? I am having issues getting specific timeline requirements for monthly documented visits to my doctor, showing attempted weight loss. I've called Cigna twice and received different answers both times :/ First they told me 6 months of documented visits and the 2nd time I called they told me 89 days. So frustrating that they don't have accurate information.

I have my first appointment with the surgeon in 2 weeks and would really like to manage my exceptions on a reasonable timeline prior to the visit.

I called them 2 weeks ago, and they told me it was just the deductible I had to worry about. No approvals. But then again, I have had them refuse to pay everything else, from a tooth implant, to an RX from doc, after blood test. They just decide what and when they want to cover something.
