I'm looking for a health insurance but from what I have found online most of them have negative reviews. Like Cigna which some linked here - on wiki it states: The CNA has determined that Cigna denies roughly 39.6% of all claims (compared to competitors such as Aetna who denied about 5.9% of all claims in the same time frame).
Two denies from every five claims sounds like a lot to me. So if something serious happens and its expensive or requires a longer period of treatment would it be possible to somehow fallback to the state insurance if the private one doesn't pay? Or is it basically if your own insurance won't pay your fu***d?
