These reported “losses” are based on chargemaster rates. When a hospital bills, they use a grossly exaggerated rate which no one takes seriously. They use it to intimidate the uninsured into buying insurance. Remember that it was the hospitals who invented Blue Cross, so they could get paid more. When dealing with hospitals using a service such as MediBid will help you to get decent rates with full transparency, not the crazy chargemaster prices.
Of course the hospitals support it, since obamacare incentivises over consumption though lowered deductibles.
