Exemption from the mandatory public health insurance for students in Germany
According to the German Social Code Book V (SGB V), as a student in Germany, you can also be exempted from compulsory public health insurance (German: GKV) and change to a German private health insurance company (German: PKV). For this, you have to make an application for exemption within the first three months after the start of your study.
The exemption request must be made to any of your local public health insurances (like Techniker Krankenkasse (TK), AOK, DAK, BKK, or BEK) at the city of your residence or place of study. This can be done in writing, and no special form is needed. The validity period for the exemption from the student health insurance in Germany is the period of study, and during this time, the exemption is irrevocable. Unless otherwise, compulsory insurance appears, such as entering into employment with full social insurance (sozialversicherungspflichtiges Arbeitnehmerverhältnis).
