I have very specific situation.
I moved to Germany last year, I am EU citizen, I work internationally out of Europe for an American company and I stay most of the time abroad. I have private corporate provided international health insurance and I earn more than 70 K Euro a year. I am 53 years old.
From above I understand that I do not need to pay in AOK for health insurance since I have higher earnings and I have private international coverage health insurance.
I hear that there is a way to pay approx 50 Euro additionally to AOK, parallel to private one, so I am insured with AOK also while I am in Germany and it will keep me in the system for time when I will be above 55 years old and will be able to be in the system when I will not have this job anymore. Am I right about this extra 50 Euro to pay to AOK parallel to my private insurance??
Or what are my options so I can ensure to have AOK once I stop working abroad and will permanently settle in Germany.
