1. What are premium regions in health insurance?

Premium regions are regional levels of health insurance premiums in certain cantons. They exist because there are sometimes significant local differences in healthcare costs. Based on these regions, health insurers are able to adjust the premiums to these costs.

2. How many premium regions are there in each canton?

There are a maximum of three premium regions per canton. In addition, there is a cap on the permissible differences in premiums between the regions.

Example of premium differences

In 2025, the average basic insurance premium for adults with a deductible of 300 francs in the city of Zurich is 573.40 francs per month. In Winterthur, people with the same insurance pay an average of only 514.80 francs. That’s because Zurich is located in premium region 1 (the most expensive), and Winterthur in premium region 2 (the cheapest).

Map of premium regions in Switzerland

The map gives you an overview of which premium region the communes in Switzerland belong to. Cantons with only one health insurance region are shown in the lightest green.

3. Who determines the premium regions?

The Federal Department of Home Affairs (FDHA) is responsible for defining the regions. The FDHA’s ordinance on premium regions specifies which commune is in which premium region.

The ordinance (Annex 2) also specifies the maximum permissible premium differences.

Good to know: the premium regions have remained largely unchanged since 2004. The FDHA only makes adjustments in the event that communes from different regions merge. However, cantons can propose changes (Art. 91b HIO) – such as reducing the number of regions from three to two, as was implemented in the canton of Vaud in 2009.
