ÖKK profile

The legal entity behind ÖKK is “ÖKK Kranken- und Unfallversicherungen AG” (legal form: company limited by shares (AG), UID CHE-106.844.103), based in Landquart. The FOPH register does not assign the insurer to any insurance group. The Federal Office of Public Health (FOPH) lists the insurer under number 455 in its register of approved health insurers, as of 01.01.2026. The register gives its area of operation as “CH; EU, EFTA, UK”. In basic health insurance, ÖKK must accept every person there who is required to take out insurance, without a health questionnaire, and the benefits are the same at every insurer under the Health Insurance Act (KVG/LAMal).

In the 2024 financial year, an average of 175,385 people had basic health insurance with ÖKK. That is 1.9% of the 9,005,998 insured persons across all insurers. These figures come from the FOPH supervisory data (table T 5.01), which are published every year for all health insurers. Per insured person, the insurer took in an average of CHF 3,808 in premiums in 2024 and paid out CHF 3,397 in net benefits.

For 2027, ÖKK has approved premiums in 26 of 26 cantons. As the reference for the premium level, we use adults in the standard model with a CHF 300 deductible and accident cover. Across all of the insurer’s premium regions, this gives an index of 94.2, where 100 is the unweighted average of all insurers in the same regions. On average, the premiums are therefore 5.8% below the average. Compared with the respective cantonal average, the lowest index is in the canton of Appenzell Inner Rhodes (91.0) and the highest in the canton of Zug (99.8).

Between 2011 and 2027, this reference premium at ÖKK changed, on average across its own premium regions, from CHF 344.62 to CHF 575.40 per month (+67.0%). Over the same period, the average of all insurers in the same regions went from CHF 343.85 to CHF 610.68 (+77.6%). The chart further down shows the trend year by year.

In 2027, ÖKK offers 4 model types: standard model (free choice of physicians), GP and HMO models, flex models and telemedicine and other models, with 5 tariffs in total, for example “ÖKK CASAMED HAUSARZT”, “ÖKK CASAMED SELECT” and “ÖKK CASAMED 24”. Models with a restricted choice of service provider often apply only in certain regions; the premium calculator for your municipality shows whether a tariff is offered where you live.

In 2024, administrative costs came to CHF 218 per insured person (all insurers: CHF 193). The claims ratio, i.e. net benefits in relation to premiums, was 89.2% (all insurers: 94.9%). Reserves amounted to CHF 143.9 million, or CHF 821 per insured person. In the KVG solvency test as of 01.01.2025, ÖKK achieved a solvency ratio of 138%; the required minimum is 100%, while the figure for all insurers was 147%.

You cancel basic health insurance in writing. To switch on 1 January, your notice of cancellation must reach ÖKK by 30 November (Art. 7 para. 2 HIA); the FOPH recommends sending it by registered mail by 15 November. The insurer’s website does not give a separate cancellation address; we show the general postal address, which you’ll find further down. Which insurer is cheaper for you depends on where you live, your age, your deductible and your model. This page shows official figures without rating; you can work out your personal premiums in the premium calculator.
