Margo, If you prefer the healthcare system of another EEA country or Switzerland, you and your British citizen husband need to move in the next few weeks, before 31 December, unless either of you can get a work visa to that country after that date.
Germany is considered to have a very good health system. That's also a system with private and public.
There is a monthly fee for healthcare, but the employer pays part of their employees health charge.
From posts on toytown, since the changes, it's now an expensive health charge for the self employed, about 1,300 euros each month; and if neither in a couple work, about 1,300 euros for each person, each month.
Under present rules, the UK pays for those not in work in Germany, if they are in receipt of a UK state pension, or receiving certain UK benefits; these apply to the UK for the S1. Other EEA/CH countres will also pay for German healthcare too, via the S1, subject to their own conditions for their S1.
Here is an article on the toytown site, about how German healthcare works
