If you are moving to Switzerland from London, Chicago, Mumbai or Singapore, you will quickly meet two words that sound alike: basic insurance and supplementary insurance. They are very different things. One is compulsory for residents. The other is a personal choice, and plenty of families live well without it.
This guide explains what supplementary health insurance in Switzerland is, what it can add, and how to think about it calmly. It does not tell you what to buy. It gives you the picture, so that a conversation with a specialist later is short and useful.
The short version
Basic health insurance is compulsory. Supplementary insurance is voluntary. Basic cover is the same in its core content for everyone, whichever insurer provides it. Supplementary cover is where insurers differ, and where each person's wishes count.
According to the Federal Office of Public Health (FOPH), anyone living in Switzerland has to take out basic health insurance no later than three months after taking up residence. If that deadline is met, cover is retroactive to the date of arrival, and premiums are due from that date. If it is missed, cover starts only when the policy begins, a surcharge may apply for an unexcused delay, and the cantonal authority can assign an insurer.
Nothing like that applies to supplementary insurance. You can skip it, add it later, or choose it on day one. One point worth knowing early: supplementary policies usually involve a health questionnaire, so the best moment to ask about them is often before any health issue appears. Details depend on the insurer.
If basic cover is still new to you, start with LAMal, the mandatory health insurance and how Swiss health insurance works, then come back here.
Basic and supplementary: who decides what
Basic insurance (called LAMal in French and Italian, KVG in German) follows federal law. Insurers cannot refuse you for it, and they cover a defined list of treatments. Supplementary insurance (assurance complémentaire, Zusatzversicherung) follows ordinary insurance contract rules. The insurer can set conditions, ask health questions, and decline an application.
That difference explains most of what newcomers find confusing:
- Basic: a legal obligation, a standard catalogue of care, no health questions.
- Supplementary: a private contract, a menu of options, and conditions set by each insurer.
- Same insurer or not: the two can be held with the same company or with different ones. This is a choice, and each approach has trade-offs a specialist can walk through.
The exact scope of any add-on is written in the policy. The general ideas below show what such products tend to address, not what any single one contains.
What supplementary cover typically adds
Supplementary products tend to fall into a few families. Not all are sold by every insurer, and the details vary widely.
Hospital comfort and choice
Add-ons of this kind usually relate to the hospital stay: a room with fewer people, more say over the doctor or the hospital, or access beyond your canton of residence. For a family, this is mostly about comfort and flexibility, not about whether a medical need is treated.
Dental and orthodontic care
Dental care is a topic that surprises many arrivals. Routine dental treatment is generally paid privately in Switzerland, and children's braces are a common reason families look at dental add-ons. Whether such a product is worthwhile depends on the age of the children, the waiting periods and the conditions in the contract.
Complementary medicine
Some add-ons contribute to treatment by practitioners of alternative methods. Readers from India or China, where traditional approaches are familiar, sometimes ask about this one. Coverage rules differ by product.
Glasses, lenses and preventive items
Other options help with eyewear, fitness programs, vaccinations beyond the standard list, or similar items. These usually pay a limited contribution, not the whole bill.
Travel and care abroad
Basic insurance is built around care in Switzerland. People who travel often, or who visit family in the UK, the US, India or the Gulf, sometimes look at add-ons for care abroad. Travel insurance bought separately is another route; see beyond health, the other insurance you may want.
What supplementary insurance does not replace
Two things are often mixed up with it.
First, it does not replace basic cover. A supplementary policy sits on top and does not satisfy the legal obligation by itself.
Second, accident cover is its own subject. For employees, accident insurance is normally organized through the employer, and the rules depend on the work contract. Read accident insurance, what your employer covers before deciding whether any gap needs filling.
Deductible and insurance model (family doctor, telemedicine and so on) are choices inside basic cover and they affect your premium. They are not supplementary products. See choosing your deductible and insurance model.
How to decide, step by step
Think of it as a short sequence that you can start from your current home.
Step 1: settle basic cover first
Basic insurance is the priority, because it is compulsory. The FOPH sets the deadline of three months after taking up residence. Choosing the insurer, the deductible and the model comes first. Supplementary cover can wait a little, though the health-questionnaire point above is worth keeping in mind.
Step 2: register where you live
The municipality asks for your arrival to be reported within 14 days in most cases, although the exact rule can vary by commune or canton. At the counter, you usually show an ID, your residence or work permit, and proof of health insurance. That is another reason to sort basic cover quickly. The practical order of these steps is in your relocation calendar.
Step 3: write down what matters to your household
A few honest questions help:
- Does a shared hospital room matter to you, or is quality of care the only concern?
- Are there children who may need braces?
- Does someone prefer a specific complementary treatment?
- How often does the family travel abroad?
Step 4: look at what you already have
Some employers offer health benefits, and some arrivals keep a policy from home. Whether any of this fits with Swiss rules is a question for a specialist who can read the actual documents.
Step 5: compare in writing
Ask for the conditions in writing: what is covered, what is excluded, what waiting periods apply, and how premiums can change over time. Compare like with like. A short call with a specialist can save many hours.
A few examples
These stories are fictional and only illustrate the thinking.
- A couple from Toronto arrives for a job. Both are healthy, travel rarely, and care mostly about hospital choice. They settle basic cover first and look at supplementary options after the first weeks, with the conditions in hand.
- A family of four from Dubai has two children close to the age when orthodontic care often starts. For them, the dental question is the main one, so they read the waiting periods closely.
- A single engineer from Bangalore is posted for a limited time. The employer already provides some benefits, so the first question is what those benefits do and do not include.
Mistakes to avoid
- Mixing up the layers. Compulsory basic cover and optional add-ons are different contracts.
- Assuming everything is paid. Some care is not covered by basic insurance, which is exactly the gap add-ons try to address.
- Waiting until a problem appears. Insurers may ask health questions, and the answers can change the outcome.
- Buying quickly from a long list. Waiting periods and exclusions sit in the fine print.
- Forgetting the review. Needs change with a new baby, a school stage or a new job.
A note on costs
Premiums for basic cover are covered in what health insurance costs. Supplementary premiums depend on the insurer, the product, age and health answers, so a specific number here would mislead. A written offer is the only reliable way to know.

Frequently asked questions
Is supplementary health insurance compulsory in Switzerland?
No. Only basic health insurance is compulsory for residents. Supplementary cover is a voluntary private contract that you can add, change or skip.
What is the difference between basic and supplementary insurance?
Basic insurance is set by federal law and covers a standard catalogue of care. Supplementary insurance is a private contract with extra options, and each insurer decides its own conditions.
When does basic insurance have to be taken out?
Anyone living in Switzerland has to take out basic health insurance no later than three months after taking up residence, according to the FOPH. If the deadline is met, cover is retroactive to the date of arrival.
What happens if the deadline for basic insurance is missed?
According to the FOPH, cover starts at affiliation, a premium surcharge may apply for an unexcused delay, and the cantonal authority can assign an insurer.
Can I get supplementary cover before I arrive?
Rules differ by insurer and product, and basic cover is tied to residence in Switzerland. A specialist can tell you what is realistic from abroad.
Can an insurer refuse me supplementary insurance?
Yes. Unlike basic insurance, a supplementary application can be declined or come with conditions, often after a health questionnaire.
Do supplementary policies ask health questions?
Usually yes. That is why people often look at them early, while their health history is simple. Exact practice depends on the insurer.
Does supplementary insurance lower my basic premium?
No. They are separate contracts with separate premiums. Basic premiums are influenced by the deductible, the model and other factors; see the page on choosing your deductible.
Does it cover dental care?
Some products contribute to dental or orthodontic care, with limits and waiting periods. Basic insurance covers dental treatment only in narrow situations, so check the policy wording.
Does it cover private hospital rooms?
Hospital-related add-ons are among the most common supplementary products. They usually deal with room type and choice of doctor or hospital. Exact content varies.
Is alternative medicine included?
Basic insurance has limited rules for complementary methods. Some supplementary products add contributions for approved practitioners. The policy lists the details.
Does it cover treatment abroad?
Basic cover is designed around care in Switzerland. Some add-ons and separate travel policies address care abroad. The terms differ, so compare them in writing.
Is my home-country policy enough in Switzerland?
A policy from the UK, US or elsewhere does not replace compulsory basic insurance for a Swiss resident. Whether it can complement it is something to ask a specialist.
What if my employer offers health benefits?
Employer benefits can reduce what you want to buy privately. Ask the employer for the written terms, and check what is and is not included.
Is accident insurance the same as supplementary insurance?
No. Accident insurance is a separate system, often arranged through the employer. See accident insurance for how it works.
Do children need their own supplementary policy?
Each person holds their own contracts, so a family sorts out each member. Families often look at dental options for children first.
Can I add supplementary cover later?
Often yes, but the insurer may ask health questions again and may set conditions. Acceptance is not assured.
Can I change supplementary insurer?
You can usually cancel and apply elsewhere, but a new insurer may ask new health questions. Check notice rules and waiting periods before leaving.
Is it worth it for a short stay?
It depends on the length of stay, waiting periods and what the employer already provides. For short assignments, the written terms matter more than the product name.
Is it worth it for a healthy young couple?
Many healthy newcomers start with basic cover only and revisit the question later. There is no single right answer, and a specialist can look at the household.
How do I compare offers without getting lost?
Ask for written conditions on the same points for each option: scope, exclusions, waiting periods and how premiums can change. Then compare line by line.
Who can explain this to me for my household?
A specialist can examine your situation and explain the options. Relocation Swiss connects you with a relocation company that fits your needs through the request at the bottom of the page. You can also try the moving checklist builder to organize the first weeks.
