Health insurance premiums 2026 in the canton of Basel-Stadt (BS)

That depends on your municipality’s premium region. For an adult without accident cover: region 0 (Basel, Riehen, Bettingen…): 411.15 CHF a month with a 2'500 CHF deductible (CSS, HMO (health practice)) and 530.45 CHF with a 300 CHF deductible.

For a child with accident cover and a 0 CHF deductible, the canton’s lowest premium is 127.35 CHF a month with CSS (HMO (health practice)).

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.

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.

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.

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.
