Swiss Health Insurance System: Structure, Costs and Switching

1. How does the health insurance system in Switzerland work?

Basic insurance is mandatory, supplementary insurance voluntary. The scope of benefits of basic insurance is legally defined and identical at all approximately 40 authorised insurers.

The system is based on four central elements:

• Basic insurance is mandatory for all. Insurers must accept every person.
• You participate in the costs via deductible and co-payment in several tiers.
• Premiums and cantonal contributions finance the system together.
• The insurers stand in competition for insured persons and premiums.

Although all insurers offer the same scope of benefits, premiums differ strongly. The most important savings options for you: insurance model, deductible level and the choice of the insurer itself.

For inpatient hospital treatments, the cantons bear about 55 % of the costs, the insurers about 45 %. The cost distribution follows the SwissDRG case flat rates. A risk equalisation between the insurers prevents selection by health risks: insurers with many older or sick insured persons receive financial compensation.

Since benefits are legally fixed, your choice of insurer directly affects your annual premium. The range between the cheapest and most expensive insurer reaches several thousand francs per year between regions.

2. Who is subject to insurance obligation and which benefits are covered?

The mandatory health care insurance (OKP) applies to all persons resident in Switzerland. You must insure yourself within three months of taking up residence or birth. With timely registration, your insurance coverage applies retroactively from the first day. Special cases such as the tariff for young adults from 19 or the registration for newcomers follow deviating deadlines.

Identical benefits at all insurers: The approximately 40 authorised insurers cover for you exactly the same medical services. Whether you choose a large or small insurer, every insurer pays for your doctor visits, hospital stays (general ward) and reimbursable medications the same. Price differences arise through administrative efficiency, reserve cushion and insured structure.

Acceptance obligation without health questionnaire: No insurer may reject your application for basic insurance, regardless of pre-existing conditions, age or place of residence. The premium is the only difference between insurers for the benefits of basic insurance.

3. How are the health insurance costs composed?

You participate in healthcare costs on three levels: premium, deductible and co-payment. The following table shows all cost building blocks at a glance.

The logic in brief: You pay the fixed premium every month. If you receive services, you must pay the first francs up to the level of your deductible yourself. After that, the insurer covers the costs, but you still pay 10 % co-payment up to maximum CHF 700 per year (children CHF 350). For inpatient hospital stays, CHF 15 per day are added. How your premium develops by age brackets and premium region depends on place of residence and life phase.

Maximum own costs per year for adults: Deductible CHF 2'500 + co-payment CHF 700 = CHF 3'200 plus hospital contribution and monthly premiums. The cost participation in detail comprises calculation examples for adults, children and hospital scenarios. How you optimise all three building blocks is shown by the ten ways to save on health insurance premiums.

4. What is the difference between KVG and VVG?

KVG and VVG form two separate legal levels. Four core features distinguish basic and supplementary insurance:

In basic insurance, contracting obligation and solidarity prevail. In supplementary insurance, contractual freedom applies. The insurer may reject applicants or attach policy restrictions.

5. Which supplementary insurance complements basic insurance?

Dental treatments, complementary medicine and hospital upgrades are not included in basic insurance. They require a supplementary insurance. This is subject to the VVG with contractual freedom and health questionnaire.

The four most important categories: Hospital upgrade (semi-private or private), dental medicine (dental hygiene to braces), complementary medicine (osteopathy, acupuncture, homeopathy) and prevention (fitness, nutrition counselling). Each category has its own waiting periods, coverage limits and conditions for acceptance. At application, a health questionnaire runs, which in case of pre-existing conditions can lead to a policy restriction or rejection.

Splitting: With splitting you can take out basic insurance with a different insurer than supplementary insurance. Your previous insurer may not terminate your supplementary insurance when switching basic insurance; both contracts remain legally independent.

6. Which deadlines and mistakes should insured persons know?

The system knows four central deadlines for registration, termination and deductible adjustment.

The notice period for supplementary insurance depends on the product and can deviate from the AVB of your contract. With a missed deadline, the existing contract is extended by one year. The termination templates contain all mandatory information in legally secure form for basic and supplementary insurance.

Premium subsidy and supervision: With low or medium income, you are entitled to the Individual Premium Subsidy (IPV). The exact income limit is set by each canton itself. Supervision over the insurers and the ordinances on OKP lies with the Federal Office of Public Health (FOPH).

Three mistakes that regularly lead to higher costs

Mistake 1: Too low deductible with good health. Many insured persons choose CHF 300, although their healthcare costs lie significantly below. The premium difference is up to CHF 1'500 per year per insurer and region. With annual healthcare costs below CHF 2'000, the high deductible is cheaper.

Mistake 2: Conclude supplementary insurance too late. For supplementary insurance, insurers examine your health status. From a certain age or with existing diagnoses, the conclusion can be more difficult for you, for example through rejections or policy restrictions. Before the first benefit, the acceptance chances are higher.

Mistake 3: Miss the notice period. A termination by phone is not valid; delivery after 30 November is not sufficient. Your termination must arrive at the insurer in writing by 30 November at the latest.

The annual check in October gives you the necessary lead time to switch on schedule by 30 November.
