Yes, but we don’t recommend that students get expat insurance in Germany since it is limited to five years.
Instead, students under 30 should look at public health insurance options as it covers nearly everything you would need for a longer period of time. If you are over 30, it might be cheaper to go on expat insurance until you finish your studies and can move to public insurance.
If you’re from the EU, you can use your EHIC (European Health Insurance Card).
Ultimately, expat insurance is for those who cannot get on public or private insurance but still need to fulfil the visa requirement or know they will only be in Germany for a limited period of time.
