So does the U.S.A. The Emergency Medical Treatment and Labor Act (EMTALA) is a federal law that requires anyone coming to an emergency department to be stabilized and treated, regardless of their insurance status or ability to pay.
What is at issue is universal health insurance which is a financing issue. Since EMTALA remains an unfunded mandate, the hospitals are on the hook.
For instance, the hospital which cares for someone without insurance has some uncertainty of payment. With universal health insurance (aka single payer), the hospital has certainty of payment.
Presently, the hospital acts as a redistributor of wealth. The hospital schedule of rates for the uninsured is exaggerated in order to collect from those who can pay to subsidize those who cannot.
