Here in Israel the majority of large health providers are essentially contractors, are largely indistinguishable and don't compete on price at all. Everybody pays a health tax as a percentage of their income. You don't have to pay anything aside from it, but if you want additional coverage like improved dental and discounts for non-essential medication, the best available coverage through the largest providers would cost you about $25 a month on top of the health tax.

I don't know in what meaningful sense Israel is a "hybrid" system, it functions almost exactly like a 'Medicare for all' type proposal would.
