Premiums Rise — But Not Freely
A private health insurer cannot simply raise your premium because it would like more income. A Beitragsanpassung (premium adjustment) is tightly regulated: it may only happen when defined cost or life-expectancy figures move beyond set thresholds, it must be checked by an independent trustee (Treuhänder), and it must be explained to you in a legally sufficient way. Understanding those guardrails turns a demoralising letter into something you can actually assess.
The trigger, not a whim: an insurer may recalculate a tariff’s premium only when actual benefits paid, or insured longevity, diverge from what was calculated by more than a legally set percentage. Below the threshold, it may not adjust; above it, it must recalculate the whole tariff’s premium, not just cherry-pick.
Why Some Increases Were Overturned
German courts, including the Federal Court of Justice, have held that a premium increase can be formally defective if the insurer’s notification failed to state the required reasons adequately — for example, not identifying which calculation factor (claims or longevity) triggered the change. Where the justification was insufficient, courts have found the increase temporarily ineffective and ordered repayment of the extra premium for the affected period, until a proper justification was given. The underlying maths was often fine; the explanation was not.
How to Review Your Own Adjustment
- Keep every adjustment letter: the justification is judged on what the insurer told you at the time
- Look for a stated trigger: the notice should indicate that a recalculation threshold was crossed and why
- Check the trustee reference: adjustments require independent trustee approval
- Note the dates: repayment claims are time-limited, so old increases may fall outside the window
Your Realistic Options
If an increase looks poorly justified, you can ask the insurer in writing to substantiate it, and — for potentially defective past increases — take specialist legal advice, since this is a developed area of case law with limitation periods. Separately, if the premium is simply becoming unaffordable, remember the internal levers: a Tarifwechsel under §204 VVG to a cheaper tariff with your accrued reserves, a higher deductible, or the Standard/Basistarif safety nets. Challenging the legality and reducing the premium are two different tracks — often worth running in parallel.
The Bottom Line
A Beitragsanpassung is lawful only when a genuine threshold is crossed, a trustee approves, and you are told the reasons properly. If that chain is intact, the increase is valid; if the justification was inadequate, past increases have been repayable. Keep your letters, read them for the stated trigger, and pursue the legal question and the affordability question on separate tracks.
