That's not how insurance works, bud. For one, you likely don't pay for insurance, its heavily subsidized by your employer, and they will determine which policies to offer you. For two, you share the risk with everyone else who has a policy with your provider.
I could see an argument for insurance companies being legislated to force them to cover more previously uncovered services, as the ACA did.
> F that, if there is any out of pocket payments at all, I should be entitled to estimates even WITH insurance and they should be legally mandated to be within 5% of the actual cost.
Sure, you are welcome to contact your insurance BEFORE you obtain services and find out what they will cover. In fact, its incumbent upon you to do that, and not expect HCP's to do that for you.
