Every person who lives or works in Switzerland must take out insurance with a certified health insurance fund. Insurance policies for the Swiss healthcare system consist of the obligatory basic insurance and the supplementary forms of insurance. What is covered by the obligatory basic insurance is legally regulated and identical for all insurance policies. What differs, however, is the amount of the premiums for the obligatory basic insurance. You have a free choice between the health insurance funds, since they must accept any person into the obligatory basic insurance.
You can adjust optional supplementary forms of insurance according to your personal needs. For example, you can take out supplements for stays in hospital, alternative medicine, non-essential forms of medication, or psychotherapy. Insurance coverage for dental treatments is not included in the obligatory basic insurance; these services can be insured by means of supplementary insurance.
