Germany's multi-payer system has significantly stricter consumer cost controls and Germany in general has more government-run health providers (eg: your out-of-pocket costs are effectively capped at a low % of your household's income). It's a good bit more socialized than Warren's and might, taken as a whole, be more socialized than even Sander's M4A plan.

Perhaps a German HNer can chime in on how frequent medical bankruptcies are in their country.
