Medical care is more or less free here. She'll have to pay a daily rate, but it's usually capped. I think that, for in-patient treatment, it's something like €10 a day, up to €100 (can't recall). The ICU treatment should be free, except for perhaps the emergency room fee (€150?) Tell her not to worry about it - she needs to concentrate on getting better. If in doubt, ask the nursing staff at ICU and they'll be able to tell you the exact information but it will not cost a lot of money - nothing like it might cost in the US, for example.
