What happens to my student health insurance when I turn 30?

Your 30th birthday is the only trigger. The old 14-semester cap was abolished in 2020, so a long Master's does not end the student rate; turning 30 does. From the next day your membership continues automatically as voluntary public insurance at roughly €250 to €280 a month. You do not have to apply for anything. The two-week letter your insurer sends is the window to leave, and leaving requires proof of other insurance, so for most students it is simply a price change.
