In 2026, 23 health insurers offer their models in the canton of Basel-Stadt. Basic insurance benefits are the same with all of them; only the premium, the model, the deductible and accident cover differ. ### Why are the premiums not the same across the whole canton of Basel-Stadt? The canton of Basel-Stadt has a single premium region: for the same offer, the premium is identical in every municipality. The amount varies by health insurer, model, deductible and accident cover, but not by municipality. ### Why is the FOPH-approved premium higher than the price shown? The large amount is the FOPH-approved premium — the same one as on priminfo.admin.ch, shown under each price — less the redistribution of the environmental levies (the CO₂ levy and the VOC incentive tax). In 2026 every insured person in Switzerland receives 61.80 CHF, which their insurer deducts from the premium invoices: 5.15 CHF a month, the same amount for everyone, whatever the insurer, the model or the deductible. The ranking is therefore unchanged. This amount is not necessarily your final invoice: your canton’s individual premium reduction or a discount for annual payment are added where they apply. For example, the approved premium of 535.60 CHF at CSS (HMO (health practice)) gives 530.45 CHF after redistribution. ### Until when can I change health insurer for 2026? Your cancellation must reach your current insurer by 30 November 2025 at the latest; the change takes effect on 1 January 2026. The premiums on this page are those approved by the FOPH for 2026.
