Kaiser is the only non-broken part of the U.S healthcare system. They have never sent me a bill for a surprise out of network anything. Out of network doctors don't work there. All doctors are on salary. You get one bill from one company. No wonder they have been growing like crazy in California.
I can just go to whatever walk-in clinic, urgent care provider or emergency room I need, depending on the severity and get treatment (I do try to go to my GP if possible, but I have many options if that's not practical for some reason).
