That used to be true now it’s worse. My hospital system and health insurer play chicken every 12-24 months. I’ll get letters saying I can’t see my doctor anymore, then they go up until some midnight deadline, make a deal, and I get an email saying I can still go to the doctor.
Sometimes it doesn’t work out through! You could have the same job, health insurance, and doctor for a decade - and ooops! The next day you have to drive an hour away to see some new doctor you never met before who isn’t as good as your doctor.
And that all comes down to this financial gamesmanship between hospitals and insurers. It’s nuts, literally the dumbest combination of petty greed and literal life altering decisions possible.
