Lisa,
I HATE insurance companies :grrr:!!! It seems like most of the time, its all about money, not about health... Anyway, I would take her to see the new doctor and INSIST that her thyroid be checked as well as her blood sugar. Just because her thyroid was checked a while ago, doesn't mean that things couldn't have changed...
I hope she gets in to see a doctor soon!!! And, I'm GLAD you didn't pay interest charges on a bill you didn't even know about!!! WFEN
