They submitted my stuff to insurance last week, and Cigna denied me because there was no medical clearance letter, but according to the policy, that's not required! SO now I am trying to do that. So, just advice for anyone else with Cigna, even if your case worker tells you that you do not need that letter, I'd get it just in case, because mine said she's had four cases rejected for the same reason in the past couple of weeks (why she didn't tell me that before submitting mine, I'll never know).
Grumble. Now to try and obtain this letter ...
