Many 2020 Democratic Presidential Candidates in the United States, including Elizabeth Warren, Bernie Sanders, and Andrew Yang, support a "Medicare for All" single payer healthcare system with zero copays and zero deductibles. Now many countries around the world have single-payer healthcare systems. But my question is, how many of those systems have zero copays and zero deductibles?
I think Canada is one example. Are there any others?
EDIT: To define terms, single-payer means that everyone has government health insurance. A copay is an arrangement where you pay part of the cost of a specific medical service (like a doctor's visit or surgical procedure) and the insurance pays for the rest. A deductible is where only if your total healthcare spending in a given period exceeds a certain threshold will the insurance pay for healthcare, and that too it will pay only for the amount exceeding the threshold, not the full amount.
