Yup. In 2006, I was in a serious bicycle accident in San Francisco w/ some head trauma. SF General was the only hospital in the area with a (Level 1?) ER that treats head trauma. I also had two broken arms. Even though I was in shock, I remember very clearly asking everyone involved in getting me from the accident site to the ER if SF General accepts Blue Cross, my insurance carrier. I was more concerned with facing a giant bill than my own health. Eventually someone said they do take Blue Cross, and I stopped worrying.
Later I came to find out that SF General bills Blue Cross, but they do not have a contract with Blue Cross. 100% of my treatment was out of network. Then I got a bill for about 50,000 USD. Between that, trying to pay for physical therapy, and a disruption to ability to earn a living at the job that paid for my healthcare, I struggled for a long time after the accident.
My main point was that your basically screwed before you arrive, and you're just gonna have to cope with it after the fact. Expecting a patient going into an emergency room to understand, or have the capacity to, navigate "the fine print" stuff is not realistic, yet that's exactly what they expect that patient to do. It is quite lame.
If all management has to do is look the other way and collect benefit (and eventually blame paramedic), they will look the other way and punish employees who took longer to get you to hospital - cause you prefered cheaper one a bit further away.
I don't expect injured patient to protect himself perfectly. However, I think we would all benefit if we labeled what happened to you accurately - a kind of fraud - instead of pretending it is ok, because system works that way.
Many people do not use them correctly; I can't blame them sometimes, when that's the only option around, but there's a whole host of issues people drift into ERs for that ought to be solved by an aspirin and a night's sleep, or an urgent care clinic. In the past five years, there's been a huge explosion of Convenient MDs and the like springing up everywhere; honestly, if you just had a nurse practitioner or PA assigned or on-call at Rite-Aids or CVSs to write scripts for no-brainer prescription medications, you'd solve half the healthcare problems people deal with.
They pay extra to small hospitals that don't receive enough privately-insured patients to break even on standard Medicare reimbursement rates. For other hospitals, they pay rates that are below-cost, and hospitals charge private insurers extra to make up the difference.
