Not sure, that's why I specified "from what I understand".
BUT, most people aren't children, pregnant, or registered unemployed/very low income, so from that point of view to me it's still an insurance-centric system.
I pay a hefty amount each month and I was sick in the past and the system was so inefficient that I had to go to private doctors and clinics just to figure out what was wrong with me. I see the public insurance payments as a tax and I have private insurance to cover the costs of private doctors/hospitals.
But maybe that's just me.
Here is a nice summary of Polish health care: https://www.oecd.org/content/dam/oecd/en/publications/report...
