Yes. Literally every other healthcare system in a state with an advanced economy. (I'd love to see a counter-example, I've gone looking and failed to find one)

[EDIT] to the downvoters: no, seriously, please post an example of, say, an OECD member state other than the US that doesn't use either explicit or implicit (single primary buyer setting prices, that is, monopsony) price controls as a major part of their healthcare policy. I assume you know of at least one, and I'd really like to know if I'm wrong about this.
