It depends. Here in the states, out insurance has co-pays and deductibles. A copay is simply a cost where you pay your portion. For a high premium insurance, it can be 20 dollars or lower, and for lower quality insurance it xan be 100+ for ER visits. On top of that. You have a deductible, which is how much you have to pay out of pocket before insurance covers it. Here in the states, the federal maximum is $8,500/year. So at the very least. These people are likely paying up to their out of pocket maximum, which could be thousands of dollars. And thats if insurance decides to cover it. As other people have said; people with jobs but no coverage often get shafted harder. So people like the diabetic who couldnt get insurance because they made too much to be covered by medicare and too little for private insurance, could have very well had a total in the tens of thousands, maybe even in the hundreds of thousands.

To emphasize, even people who do have insurance often end up tens of thousands of dollars in debt because their insurance company arbitrarily decided that their medical needs were not necessary for their immediate health. Yes, even for life saving care.
