CSS Insurance – your health insurance

Most Trusted Brand 2018

Choosing your health insurer is a matter of trust. With CSS, you have an insurer which can look back upon 120 years of experience, and which provides those it insures with a personal service.

Who is CSS Insurance?

Founded as a Christian self-help organisation by 60 women and men in St. Gallen in 1899, CSS has since become one of the leading health insurers in Switzerland. The abbreviation CSS stands for "Christian Social Switzerland" and dates back to that time.

In 1947, the number of persons insured with CSS reached 200,000 for the first time; in 1987, the threshold of one million was exceeded. In 2004, CSS acquired the customers and staff of Accorda and founded the Arcosana AG health insurance company. In 2005, Auxilia Kranken-Versicherung AG became part of CSS Group, and three years later CSS Group also acquired INTRAS, with head office in Geneva.

CSS Group

The CSS Group comprises CSS Holding AG and its subsidiaries. With a total of 1.7 million insured persons, it is one of the leading health insurance providers in Switzerland.
