A decision to be exempted from the mandatory health insurance scheme for students should be considered carefully. The exemption cannot be revoked and applies for the full duration of your studies, meaning that you cannot apply for coverage from other health insurance providers.
Once an exemption has been granted, privately-insured students can no longer switch to a statutory health insurance provider during their studies.
If you take on an unpaid internship or are initially unemployed after graduating, for example, you will still have to pay your private health insurance (private Krankenversicherung, or PKV, in German) premiums.
As a privately-insured student, the exemption from mandatory insurance can result in significantly higher costs than if you opt for statutory health insurance.
