Question 1

Are all public health insurers required to provide the same coverage?

Accepted Answer

Yes. About 95% of coverage is identical across all public health insurers (gesetzliche Krankenkassen) because it is defined by law. The differences are in the Zusatzbeitrag (additional contribution rate), bonus programs, extra services (travel insurance, online therapy), app quality, and customer service experience.

Question 2

Can I use private health insurance as a student in Germany?

Accepted Answer

Students under 30 enrolled at a German university must choose public health insurance. You can only opt for private insurance if you formally exempt yourself from public insurance at enrollment, but this decision is binding for the entire duration of your studies. Private insurance is cheaper initially but has significant risks: no family coverage, premiums rise with age, and switching back to public insurance is very difficult.

Question 3

What happens to my health insurance after I turn 30?

Accepted Answer

The subsidized student rate ends when you turn 30 (or after your 14th semester). You then switch to voluntary public insurance at the full rate (~€220 to €280/month) or private insurance. If you start working, your employer covers roughly half of the public insurance premium.

Question 4

How do I register for public health insurance?

Accepted Answer

You can register online with TK or Barmer (or visit an AOK branch). You need your passport, university enrollment letter, and German address. After registration, you receive a membership confirmation (Mitgliedsbescheinigung) that you submit to your university to complete enrollment. TK typically processes this within 1. 2 business days.

Question 5

Can I switch health insurance providers?

Accepted Answer

Yes. After being with any public insurer for at least 12 months, you can switch to another by simply signing up with the new provider. They handle the cancellation of your old membership. The switch takes effect at the start of the following month after a notice period.

Question 6

Which insurer should I choose if I do not speak German?

Accepted Answer

TK (Techniker Krankenkasse) is the strongest recommendation for international students who do not speak German. They offer a fully English website, English-speaking customer service by phone and chat, and a well-designed app that works in English. Barmer is improving its English support but is not yet on par with TK.
