I'm a German national. My mother is German, too but my father is a non-EU national. Both of my parents are older than 55.
I'm now thinking of moving to Germany, and some websites claim if I join the public healthcare system, and if my parents don't work, and if we live at the same address, my parents would be covered by my insurance even if they are above 55.
However I haven't been able to get definite confirmation and some other websites claim that this is not the case and there is no way to get coverage by public healthcare if one is above 55 and wasn't covered by the public healthcare system in the past 5 years.
Does someone have a reliable source that can clarify this point?
