Basically what the title says. In July of last year I got bloodwork done at my doctors office back home after graduating from a 4 year university. A few months later I get a bill for 700$ saying that they charged it to my former school's insurance as opposed to my CA state insurance. I've gone to my doctor's office multiple times and each time they've said they'll handle it but quest keeps sending bills I'm back in college and need to save as much as I can, is there a way to resolve this with quest? A relative is saying I should send a notarized letter explaining the situation, but I've also heard if I call quest and give them my CA state insurance info it should be better. Is that still possible, or has too much time passed? What's the best thing to do now
