New to Switzerland? Health insurance is one of the first financial decisions you need to make. Most people who take up residence in Switzerland must arrange compulsory health insurance within three months. If you enrol on time, cover and premiums generally apply retrospectively from the start of your residence.
The important point for expats is that “the cheapest insurer” and “the best health insurance” are not the same question. Basic benefits are defined by law, but premiums, service models, deductibles and supplementary cover can make a substantial difference to your experience and annual cost.
The expat health-insurance checklist
| Decision | What to check |
|---|---|
| Basic insurance | Choose an authorised insurer; compulsory benefits are standardised. |
| Deadline | Normally within 3 months of taking up residence. |
| Deductible | Adults can choose CHF 300 to CHF 2,500, depending on the model offered. |
| Care model | Standard, family-doctor, HMO or telemedicine models may affect premiums and how you access care. |
| Accident cover | Check whether your employer already covers non-occupational accidents. |
| Supplementary cover | Optional; underwriting and exclusions can apply. |
1. Start with compulsory basic insurance
Swiss compulsory health insurance (KVG/LAMal) covers a legally defined package of healthcare benefits. Insurers offering basic insurance must accept eligible applicants regardless of health status and may not impose exclusions or waiting periods for the compulsory cover.
This means an expat should not choose basic insurance because one provider claims to cover more standard medical treatment than another. Instead, compare the premium, service, care model, administration and how conveniently the model fits your preferred way of seeing a doctor.
2. Understand what you actually pay when you use healthcare
Your premium is only one part of the cost. Adults normally have an annual deductible, followed by a 10% retention fee on further covered costs up to the statutory annual limit. A hospital contribution can also apply for inpatient stays.
The standard adult deductible is CHF 300. Higher optional deductibles can reduce monthly premiums, with adult options extending up to CHF 2,500. A high deductible can work well for someone with low expected healthcare use and sufficient emergency cash, but it is not automatically cheaper once medical spending rises.
A simple way to think about the deductible
Do not ask only, “How much can I save each month?” Ask, “Could I comfortably pay my deductible plus the applicable co-payment if I needed treatment unexpectedly?” That turns a premium comparison into a risk decision.
3. Choose a care model that fits your life
Lower-cost models often place rules around the first point of contact. You may need to call a telemedicine service, visit a designated HMO network or consult your nominated family doctor before seeing a specialist. These restrictions can be perfectly suitable, but an expat who travels frequently or strongly values unrestricted access should understand them before choosing solely on price.
4. Decide whether you need supplementary insurance
Supplementary insurance is separate from compulsory basic insurance. Depending on the policy, it may address areas such as private or semi-private hospital accommodation, broader hospital choice, alternative treatments, routine dental benefits, preventive services or other extras.
Unlike basic insurance, supplementary insurers can assess health information, impose conditions or decline an application. That distinction is particularly important if you are considering cancelling existing supplementary cover: secure acceptance for replacement cover before terminating a policy you may later struggle to obtain again.
5. What expats often get wrong
- Waiting until the end of the three-month period. Starting early gives you time to compare properly.
- Assuming a high deductible is always cheaper. Compare total annual cost under low- and high-use scenarios.
- Duplicating accident cover. Employees working sufficient hours for the same employer may already have non-occupational accident insurance through work.
- Treating supplementary insurance like basic insurance. The acceptance rules are different.
- Ignoring a future move. Cross-border and international circumstances can change which system applies.
What if you live in Zurich, Zug, Geneva or Lausanne?
Basic benefits remain the same, but premiums can vary by canton and premium region. Location therefore matters to price even when the statutory benefits do not change. Use your actual Swiss place of residence when comparing premiums rather than relying on a national “average”.
Quick answers for newcomers
Is Swiss health insurance mandatory for expats?
For most people taking up residence in Switzerland, yes. There are exceptions, particularly where international social-security coordination applies.
Can a basic insurer reject me because of a pre-existing condition?
No, not for compulsory basic insurance when you are subject to the Swiss insurance requirement. Supplementary insurance is different.
Is dental care included?
Routine dental treatment is generally not covered by compulsory insurance, except in specific medically defined circumstances.
Should I choose the CHF 2,500 deductible?
Only after comparing the premium saving with the additional amount you could have to fund yourself. Your expected healthcare use and cash reserves matter.

Insurance and financial planning is rarely a one-size-fits-all decision. Your canton, employment status, family situation, existing cover and longer-term plans can materially change the answer.
