ROUTE
Switching Health Insurance Fund
Hundreds of euros a year for one application: when switching pays, the special termination right after increases, and the procedure where the new fund does everything.
β Checked: 15/08/2026
β οΈ First, who this route is for: people in the statutory system (GKV). Anyone privately insured does not switch a "Krankenkasse" but a tariff or an insurer β under entirely different rules, with health underwriting and none of the deadlines described here. And the way back from private to statutory is narrow: employees only below the annual earnings threshold, and from 55 it is effectively shut. Look at your card: if it names a fund such as TK, AOK or Barmer, you are in the right place.
βΊ More about this route
Core benefits are identical across all statutory health insurers by law: the same doctors, the same hospitals, the same prescriptions. What differs is the price β the Zusatzbeitrag, a supplementary contribution each fund sets itself, with a spread of roughly one to two percentage points of your income. On a decent salary that is several hundred euros a year for exactly the same healthcare.
The route has three steps: work out whether switching pays off in your case, file a single application, and check the result. The decisive change came in 2021 β you no longer cancel your old fund yourself. You apply for membership with the NEW insurer, which cancels the old one and notifies your employer. They cannot refuse you: statutory insurance carries an obligation to accept, and there is no health assessment.
The timing is straightforward: 12 months of minimum membership, then a two-month notice period β the switch takes effect at the start of the third month after your application. A separate window opens whenever contributions rise: the increase letter triggers a special right of termination, and the 12-month rule no longer holds you.
WHERE PEOPLE MOST OFTEN LOSE MONEY AND TIME
- Cancelling your old fund yourself βjust in caseβ. Since 2021 the new insurer handles it through an electronic procedure; an extra cancellation only creates a risk of a coverage gap where there should be none.
- Letting accumulated bonus points expire before you switch. They do not transfer β and many funds pay β¬50β150 a year for sports and preventive check-ups.
- Forgetting the chronic-care programme (DMP). With diabetes, asthma and similar conditions you re-enrol with the new fund at your first doctor's visit; a gap costs co-payments and continuity of care.
- Binning the letter announcing a contribution increase. It is not just information, it is your window: the special right of termination applies regardless of the 12-month rule, and that is exactly when comparing pays off most.
FREQUENTLY ASKED QUESTIONS ABOUT THIS ROUTE
How long does it take from applying to the first payslip with the new contribution?βΎ
Usually about three months: two months' notice, with the switch effective from the start of the third month after your application. The new card arrives one to two weeks before membership begins, and the payslip after that should show the new Zusatzbeitrag.
Will I be uninsured for even a day in between?βΎ
No. The electronic procedure joins the dates: the old membership ends exactly when the new one starts. Until the new card arrives the old one generally still works, so a doctor's appointment during the transition is not a problem.
What should I do BEFORE filing the application?βΎ
Three things: redeem your old fund's bonus points, note your current Zusatzbeitrag from a payslip as your comparison figure, and check which benefits that matter to you the new fund covers β osteopathy, dental cleaning, chronic-condition programmes. None of this can be caught up on after you apply.
Is switching worth it on a modest income?βΎ
The contribution is a percentage of income, so the saving scales with your salary: substantial on a high income, modest on a small one. In that case look less at tenths of a percentage point and more at bonus programmes and coverage β cashback for sports and prevention can be worth more than the contribution difference.
