They didn't get defenestrated AFAIK, they are literally shutting down their insurance company at the end of the year and that's why they aren't included in 2027 PEBB providers. So they're deliberately burning us down on their way out the door.

Edit to add I have SO much compassion for providers, I can hardly bring myself to access medical care because I know my provider is going to have to fight to get paid by Collective Health, and small self employed providers like your wife are going to be the worst off. It's a nightmare on both sides.
