The Short Answer
It depends on your age, health, and priorities. Swiss basic health insurance (KVG) covers a solid range of medical treatments, but it has clear gaps — no dental care, no private hospital rooms, limited coverage for glasses, and restricted access to alternative therapies. Supplementary insurance (Zusatzversicherung), governed by the VVG (Federal Insurance Contract Act), fills those gaps. Whether it is worth the CHF 30 to CHF 200 per month depends on what you actually need and, critically, whether you can still pass the health questionnaire to get accepted.
Key Difference: KVG vs VVG
Basic health insurance (KVG) must accept everyone regardless of health status. Supplementary insurance (VVG) is voluntary and private — insurers can reject your application or exclude pre-existing conditions. This is the single most important thing expats need to understand: you cannot simply buy supplementary insurance whenever you want. If you wait until you need it, you may be too late.
Types of Supplementary Insurance
Swiss supplementary insurance is not a single product. It is a collection of separate policies that you can mix and match. Here are the main categories:
Hospital Insurance (Spitalzusatzversicherung)
Basic insurance covers treatment in a general ward (shared room) at your canton’s listed hospitals. Hospital supplementary insurance upgrades your stay in two ways:
- Semi-private (Halbprivat): Two-bed room, choice of senior physician, free choice of hospital across Switzerland.
- Private (Privat): Single room, choice of chief physician, free choice of hospital across Switzerland and sometimes internationally.
Typical costs range from CHF 100 to CHF 400 per month depending on the level, your age, and your canton. Semi-private is roughly half the cost of private. The main benefit beyond room comfort is the free choice of hospital — without this coverage, if you choose a hospital outside your canton’s list, you may face significant out-of-pocket costs.
Outpatient Supplementary (Ambulante Zusatzversicherung)
This is the most popular and versatile category. It typically covers:
- Alternative medicine: Acupuncture, osteopathy, Traditional Chinese Medicine, homeopathy, naturopathy — up to CHF 1’500 to CHF 5’000 per year.
- Glasses and contact lenses: CHF 150 to CHF 300 per year (basic insurance contributes nothing for adults).
- Preventive check-ups: Annual health screenings, vaccinations not on the federal list, travel vaccinations.
- Fitness contributions: Many insurers pay CHF 200 to CHF 500 per year towards gym memberships or fitness courses.
- Emergency transport and rescue: Helicopter rescue in the Alps, ambulance costs beyond what basic insurance covers.
- Worldwide emergency coverage: Extended travel medical coverage beyond the basic KVG scope.
Premiums typically range from CHF 30 to CHF 80 per month. Products like SWICA COMPLETA, Helsana TOP, and CSS myFlex are popular in this space.
Dental Insurance (Zahnversicherung)
Swiss basic insurance does not cover routine dental care — no check-ups, no cleanings, no fillings, no orthodontics. Dental supplementary insurance reimburses 50% to 75% of dental costs, typically capped at CHF 1’000 to CHF 3’000 per year. Premiums run from CHF 20 to CHF 50 per month. The catch: most insurers require you to apply before age 30 (or even earlier for some products), and a dental check-up confirming good oral health is usually mandatory.
Travel Insurance (Reiseversicherung)
If you travel frequently, a travel supplementary policy covers trip cancellations, lost luggage, and extended medical treatment abroad beyond what KVG provides. Costs are modest — CHF 50 to CHF 150 per year. Some outpatient supplementary policies include travel coverage, so check for overlap before buying separately.
What Does Supplementary Insurance Cost?
| Type | Monthly Premium (Age 25–35) | Monthly Premium (Age 45–55) | Key Benefit |
|---|---|---|---|
| Outpatient supplementary | CHF 30–60 | CHF 50–100 | Alternative medicine, glasses, fitness, prevention |
| Hospital semi-private | CHF 80–150 | CHF 200–400 | Two-bed room, free hospital choice |
| Hospital private | CHF 150–300 | CHF 350–700 | Single room, chief physician, free hospital choice |
| Dental | CHF 20–40 | CHF 30–50 | 50–75% of dental costs, capped annually |
| Travel | CHF 5–12 | CHF 8–15 | Trip cancellation, luggage, extended medical abroad |
These are indicative ranges. Premiums vary significantly by insurer, canton, and individual health profile. Unlike basic insurance, supplementary premiums are not regulated — insurers set their own prices and can increase them at any time.
The Health Questionnaire Barrier
This is where supplementary insurance fundamentally differs from basic insurance. When you apply for any VVG product, you must fill out a health declaration (Gesundheitserklärung). The insurer will ask about:
- Current and past medical conditions
- Ongoing medications
- Past surgeries and hospitalisations
- Mental health treatments (therapy, psychiatry)
- Chronic conditions (allergies, back problems, migraines)
Based on your answers, the insurer can:
- Accept you with full coverage
- Accept you with exclusions (e.g., “everything except back-related treatments”)
- Accept you with a premium surcharge
- Reject your application entirely
Critical Advice
Never lie on the health questionnaire. Swiss insurers have the right to investigate claims retroactively for up to five years. If they discover undisclosed conditions, they can void your policy entirely — and you lose all premiums paid. Be honest, but also be strategic: apply when you are healthy, ideally as early as possible.
Why Age Matters: Apply Young
Supplementary insurance premiums increase with age, and the health questionnaire becomes harder to pass as you get older. Here is the golden rule:
- In your 20s: You are almost guaranteed acceptance with no exclusions. Premiums are at their lowest. This is the ideal time to lock in hospital and dental coverage.
- In your 30s: Still generally good odds, but dental insurance options begin to narrow. Some products have hard cut-offs at age 30.
- In your 40s and beyond: Premiums are significantly higher. Pre-existing conditions (back pain, hypertension, mental health history) make acceptance harder. Hospital private coverage may become prohibitively expensive.
The pragmatic advice: apply for any supplementary insurance you might want while you are young and healthy, even if you do not actively use it yet. The premiums at age 25 are modest, and you secure coverage before any health issues arise.
When Supplementary Insurance Is Worth It
- You value alternative medicine: If you regularly use acupuncture, osteopathy, or TCM, an outpatient supplementary policy paying CHF 2’000 to CHF 5’000 per year for these treatments quickly pays for itself.
- You wear glasses or contact lenses: Basic insurance pays nothing for adult vision correction. CHF 300 per year towards lenses adds up.
- You want hospital comfort and choice: If being treated by a chief physician in a private room matters to you — or if you live near a cantonal border and want to choose any hospital in Switzerland — hospital supplementary insurance is the only way.
- You have children: Children’s dental insurance is inexpensive and covers orthodontics, which can cost CHF 5’000 to CHF 15’000 without insurance. Apply at birth.
- You are young and healthy: Lock in coverage now before health issues arise.
- You exercise regularly: Many outpatient plans reimburse CHF 200 to CHF 500 per year for gym memberships or fitness courses, which can offset a significant portion of the premium.
When It May Not Be Worth It
- You are healthy and rarely visit doctors: If you only see a doctor once a year for a check-up, the maths may not work. You would be paying CHF 400 to CHF 1’000 per year in premiums for coverage you barely use.
- You are older with pre-existing conditions: If you are over 50 and in good health, you might get accepted — but premiums for hospital private coverage could exceed CHF 500 per month. At that point, self-insuring (setting money aside) may be more economical.
- You are on a tight budget: Basic insurance already provides comprehensive coverage. If every franc counts, focus on keeping your KVG premiums low with a higher franchise rather than adding supplementary products.
- You already have employer-provided benefits: Some Swiss employers offer group supplementary insurance at discounted rates. Check with your HR department before buying individually.
Practical Tips for Expats
- Apply within your first three months in Switzerland. You have a mandatory KVG registration window. Use this period to also apply for supplementary insurance — insurers are more flexible during initial registration.
- Compare products, not just prices. A CHF 40/month outpatient plan that covers CHF 5’000 in alternative medicine is better value than a CHF 30/month plan capping at CHF 1’000.
- Read the conditions carefully. Waiting periods of 6 to 24 months are common, especially for dental and maternity-related benefits.
- Consider a package deal. Buying basic and supplementary insurance from the same insurer sometimes unlocks discounts, though you are never obligated to bundle them.
- Review annually. Unlike basic insurance (where you can switch every year), supplementary insurance often has longer notice periods — typically three months before the end of the calendar year. Mark your calendar.

Frequently Asked Questions
Can I be rejected for supplementary insurance?
Yes. Unlike basic health insurance (KVG), which must accept everyone, supplementary insurance (VVG) is private and voluntary. Insurers can reject applications based on health history, age, or risk profile. They can also accept you with exclusions for specific conditions or charge a higher premium.
Can I switch supplementary insurance providers?
Yes, but it is more complicated than switching basic insurance. You must pass the new insurer’s health questionnaire, and there is no guarantee of acceptance. Always secure the new policy before cancelling the old one. Notice periods are typically three months before the end of the year.
Does supplementary insurance cover maternity?
Basic insurance covers all standard maternity care. Supplementary hospital insurance upgrades your room during delivery (semi-private or private). Some outpatient supplementary plans cover additional maternity benefits like extended midwife visits or prenatal yoga. Most have a waiting period of 12 to 24 months for maternity-related claims.
Is supplementary insurance tax-deductible?
Yes. Supplementary insurance premiums can be deducted from your taxable income as part of your total health insurance and accident insurance deductions. The deduction limits vary by canton. In Zurich, for example, the maximum deduction for a single person (including basic insurance) is CHF 2’800 per year.
What happens to my supplementary insurance if I leave Switzerland?
Most supplementary insurance contracts end when you deregister from Switzerland. Some hospital insurance products offer a conversion to international health coverage. Check the terms of your specific policy. You are generally not entitled to a refund of premiums paid for the period you were covered.
Should I get supplementary insurance for my children?
Dental insurance for children is strongly recommended — apply at birth or as early as possible. Orthodontic treatment alone can cost CHF 5’000 to CHF 15’000. Outpatient supplementary insurance for children is also relatively inexpensive (CHF 10 to CHF 30 per month) and covers alternative medicine, glasses, and preventive treatments that basic insurance does not.
Can my employer provide supplementary insurance?
Yes. Some employers offer group supplementary insurance plans, often at reduced premiums and with simplified health checks. This is common for hospital semi-private or private coverage. Ask your HR department. If you leave the employer, you can usually convert the group policy to an individual one, though the premium may increase.
