CSS can look back on 120 years of experience. When it comes to their health, more than 1.6 million people place their trust in the CSS Group.
The CSS Group was founded in 1899 and has its headquarters in Lucerne. Drawing on its long and proud tradition, the company is now one of Switzerland's leading health and property insurers. It is the market leader in basic insurance. CSS produces information that provides its clients with guidance and support in making decisions regarding health and healthcare.
In 1947, the number of persons insured with CSS reached 200,000 for the first time; in 1987, the company passed the one-million-client milestone. CSS acquired the customers and staff of the Accorda general health insurance company in 2004 and founded Arcosana. In 2005, Auxilia Kranken-Versicherung AG became part of the CSS Group, followed three years later by INTRAS Kranken-Versicherung AG. In 2020, the subsidiary Sanagate AG was also merged more closely with the Group at the organisational level. As of 1 January 2022, adjustments were made to the Group structure. As providers of basic insurance, the companies Intras and Sanagate were merged with Arcosana.
