Extensively, I had signed up for insurance that took her through a broker, had to let to go because the coverage was not enough and I still ended up paying out of pocket for most things. But even with insurance we were turned away at specialist offices because the passport was not up to date and the office staff refused to take it. She could only go to a doctor (family friend) who knew of our situation, but she's getting older and her ailments are beyond a basic GP.
