So according to your response they don't die from a doctor refusing to provide care as much as they die from fear of bankruptcy? Aren't they poor? So isn't it safe to assume they don't have tons of assets to lose when bankruptcy actually happens? (Also it doesn't even really work that way https://www.bloomberg.com/view/articles/2017-01-17/the-myth-...)
Once again, emergency services are required to see you without payment in advance. Treating an ongoing condition requires multiple visits to a doctor who is not going to see you if you don't pay. By the time a chronic condition gets bad enough to qualify as an emergency, it's often too late to treat.
...Did you read that article you linked to? It outright says "I do think medical bills contribute to or cause a significant number of bankruptcies."
But I'm talking about deaths, I have yet to see even one case yet this is supposedly an epidemic. Sorry if I'm not convinced by statistical handwaving.
