November 30 passes quietly each year. In mid-January, across Switzerland, the same calculation plays out in thousands of households: how much could we have saved? The answer is almost always CHF 500 or more per adult — sometimes significantly more. The legal coverage package is identical across all Swiss basic insurers. Swiss law mandates this. Only the price differs, and the price difference is real.
A household that actively manages its health insurance decisions each year can save CHF 3'000–6'000 annually compared to one that auto-renews. The math is not complicated. The barrier is mostly inertia.
What KVG Covers — and Where It Stops
The Krankenversicherungsgesetz (KVG) — LAMal in French — makes basic health insurance mandatory for every resident in Switzerland, with no exceptions based on income, employment, or nationality. New arrivals have exactly 90 days from registration to enroll. Miss the window and the cantonal authority assigns you to any insurer they choose, typically not at favorable rates. This happens to newcomers with some regularity.
Basic coverage includes outpatient visits, general ward hospitalization within your canton, emergency care, most prescribed medications, and defined preventive screenings. Dental treatment falls outside it — with narrow exceptions. Eyeglasses, most alternative medicine, and private hospital rooms are also excluded. These are the gaps supplementary insurance (VVG) fills, under completely different rules from basic KVG.
Two insurers offering legally identical basic coverage can charge CHF 100 or more difference per month. Shopping annually isn't optional diligence; for most families it's the single most accessible annual cost reduction available.
The Franchise Decision — Binary, Not Graduated
The annual deductible — Franchise — runs from CHF 300 (minimum) to CHF 2'500 (maximum). Above the franchise, a 10% Selbstbehalt applies until an annual cap of CHF 700 is reached. Total maximum out-of-pocket per year with the highest franchise: CHF 3'200.
For a healthy adult, the premium reduction from choosing the maximum franchise versus the minimum typically runs CHF 800–1'500 annually depending on insurer and region. Even in a year with moderate medical costs, the saving usually holds. Mid-tier franchises — CHF 1'000, CHF 1'500 — are mathematically inferior in nearly every realistic scenario. They reduce the premium less than the maximum while protecting less than the minimum. Unless you can predict your costs will land in a specific narrow band, the rational choice is binary: minimum if you expect significant costs, maximum if you're healthy.
Models: Where the 15–25% Discount Comes From
The standard model — Freie Arztwahl — gives unrestricted access to any doctor. It's also the most expensive option by a significant margin. Three alternatives generate real discounts without changing the legal benefit package you receive.
Telmed requires a call to a medical hotline before any non-emergency visit. The hotline triages and refers; many straightforward cases resolve on the call. Discounts: 15–20%. HMO assigns a group practice as first point of contact — often modern, well-staffed, with in-house diagnostics. Discounts: 15–25%. The Hausarzt model centers on a named individual doctor rather than a practice.
A family of four switching from free-choice to Telmed can realistically save CHF 2'000 annually on premiums alone. Care quality in alternative models is regulated and comparable — the inconvenience is making a phone call before a non-emergency visit, which most people find minor in practice.
Supplementary Insurance: The Window That Closes
Basic KVG cannot reject any applicant, regardless of health history. Supplementary VVG products can — and do. Medical questionnaires, exclusions for pre-existing conditions, outright decline. The window to obtain comprehensive supplementary coverage is when you're young and in good health. It doesn't stay open indefinitely.
Hospital supplementary insurance is worth prioritizing: the difference between a public general ward and a private room with specialist access is meaningful, and a 30-year-old's premium is a fraction of a 50-year-old's. Keep supplementary and basic insurance with different providers. This is the most important tactical point in Swiss insurance management — it preserves full freedom to switch basic insurers every November without your supplementary coverage being used as a retention tool.
