Actually what happened was he got into a wreck while on the job (most likely his fault as you pointed out) and he didn't have full coverage (aka collision coverage). He went to the hospital and was treated but the hospital doesn't take his insurance and/or the insurance company deemed it not covered because it was on-the-job injuries. He got a bill from the hospital. He went on Twitter to bitch. He opened a gofundme campaign to pay for his medical bills.
You bet your ass a hospital can turn you away even in an emergency situation if you don't have insurance or the "right" insurance as long as they don't get any federal funding. It had happened to my little sister more than once when she didn't have insurance and went to the ER.
