Why the first policy is often taken out in a hurry
Anyone taking up residence in Switzerland must join a health insurance fund within three months of arrival. This deadline, set by the KVG/LAMal, pushes many newcomers to sign a contract quickly, often on the recommendation of an employer, an acquaintance or an adviser met by chance. The choice then hinges on immediate availability rather than a considered comparison of premiums, deductibles and models.
This haste is understandable: without affiliation, access to reimbursed care remains uncertain, and an unjustified delay exposes you to a premium surcharge. Once settled, with a permit, a fixed address and a better grasp of the system, many realise the fund they chose does not match their actual needs. The good news: this first choice is not final and can be reviewed.
The retroactive effect of the first affiliation
When you take out insurance within three months of taking up residence, coverage applies retroactively from the day of your arrival. Care received between settling in and signing the contract is therefore covered under the rules of basic insurance. This mechanism protects the newcomer, but it also means you are considered insured from the outset, with all the obligations that follow.
In concrete terms, your basic contract is an ordinary KVG/LAMal contract, subject to the same cancellation rules as that of a long-term resident. Having arrived during the year does not create a special right to cancel: you cannot annul the contract on the grounds that it was signed quickly. On the other hand, you enjoy exactly the same switching options as any other insured person.
The legal deadline for changing your basic fund
Compulsory basic insurance can be cancelled with effect from 31 December, provided your letter reaches your fund by 30 November at the latest. The new contract then takes effect on the following 1 January, with no break in coverage. This is the most common route for leaving a fund chosen in haste once your situation has stabilised.
A second option exists for insured persons on the standard model with the minimum deductible who have not received a premium increase: three months' notice for the end of a half-year, meaning effect on 30 June. Alternative models (family doctor, telemedicine, HMO) often restrict this option. Check the terms of your contract before acting, as the model chosen under pressure determines your room for manoeuvre.
Extraordinary cancellation in the event of a premium increase
If your fund announces a premium increase for the following year, you have an extraordinary right of cancellation. You may leave your basic insurer with effect from the end of the month before the new premium takes effect, giving one month's notice. For a newcomer who signed up without comparing, this annual notice is often the first concrete opportunity to review the choice.
This right applies even if you benefit from a discount tied to a particular model, as soon as the actual premium rises. The cancellation letter must respect the stated deadline and reach the fund in time. It is a valuable lever for correcting a poorly suited initial affiliation without waiting for the ordinary year-end deadline.
Preparing the switch with no gap in coverage
Before cancelling, identify your new fund and make sure it will admit you: for basic insurance, the duty to admit guarantees that any insurer must accept you, with no reservation and no health questions. Join the new insurer first, then send your cancellation to the old one. Coverage is interrupted only once the new contract is confirmed.
Use this switch to review your entire coverage: deductible level, insurance model and the real needs that have emerged since you settled in. The choice made in the rush of the first months was rarely optimised. A calm comparison, based on your stabilised situation, often reveals significant percentage savings while keeping an equivalent level of benefits as provided by law.
The separate case of LCA/VVG supplementary cover
If, in your hurry, you also took out supplementary insurance (LCA/VVG), be aware that it follows different rules. Unlike basic insurance, supplementary cover is not subject to the duty to admit: a new insurer may refuse your application or impose reservations depending on your health. Their cancellation deadlines, often annual with three months' notice, are set by the general terms of the contract.
Before cancelling a supplementary policy chosen in haste, first check that you will be accepted elsewhere on the same terms. It is wise not to cancel the old cover before obtaining written confirmation of the new one. Treat basic and supplementary insurance separately: their deadlines and constraints do not necessarily coincide, especially for a file opened mid-year.
Frequently asked questions
Can I immediately cancel the fund I rushed to choose on arrival?
No. Your basic contract follows the ordinary KVG/LAMal rules. You do not have a cancellation right specific to newcomers. You can, however, cancel with effect from 31 December (letter received before 30 November) or use the extraordinary cancellation when a premium increase is announced.
Does arriving mid-year change the deadlines?
No. Once your affiliation is effective, retroactive to your arrival date, you are an ordinary insured person. The cancellation deadlines are the same as for any resident: effect on 1 January with notice by 30 November, or extraordinary cancellation when a new premium is announced.
Is there a risk of a gap in coverage if I switch?
No, if you proceed in the right order. First join the new fund for basic insurance, whose admission is guaranteed by law, then cancel the old one. The cancellation only takes effect once the new insurer confirms it will cover you, which prevents any insurance gap.
