They would do it.If she had to have urgent surgery it would be in the $100,000’s. Would they just send her home for palative care? I know they do that a lot when people’s insurance runs out.
All of this shit is automated now. If you go into an ER and symptoms/test results from triage tick certain boxes, the computer will flag that value and the provider would be compelled to admit you. You will not be turned away if you have a health condition that is imminently life threatening, no matter the cost.
