A single payer refers to a system in which one entity (usually the government) pays all the medical bills for a specific population. And usually (though, again, not always) that entity sets the prices for medical procedures. A single-payer system is not the same thing as socialized medicine. In a truly socialized medicine system, the government not only pays the bills but also owns the health care facilities and employs the professionals who work there. The Veterans Health Administration is an example of a socialized health system run by the government.
