So, initially I had been a little skeptical about ... why don't they have insurance? It's well known that they have some pretty significant benefactors. But upon reading the link I find that she needed some surgery that could only be performed by some specialists in Germany, and that insurance didn't cover it. I think that's important to call out here, because if the Sisters didn't have health insurance due to their being cheap, then one needs to begin asking whether or not they can afford to have the Sisters there at all.
Yes, these followon operations ... are they also not covered by insurance ... and do they also need to be done in Germany? Those other ones sound more routine.
