Cross-border worker in Geneva: LAMal or CMU in 2026?
Cross-border worker living in France and employed in Geneva: compare the LAMal premium and the CMU contribution across 3 income levels, then decide according…
Legal framework: right of option, 3-month deadline, binding choice
Three months: this is the period a cross-border worker has to exercise the right of option after starting work in Switzerland. Once this period has passed without an express choice, affiliation to the LAMal (Federal Health Insurance Act) applies automatically, with retroactive effect from the start of employment.
The right of option concerns cross-border workers residing in France, as well as their dependants. Two routes exist: the Swiss LAMal, or the CMU (couverture maladie universelle, universal health coverage), the French scheme attached to the Sécurité sociale. Opting for the CMU requires a form to be filed with the French health insurance fund. Choosing the LAMal means taking out a policy with an authorised Swiss insurer.
The choice is in principle irrevocable. According to the Federal Office of Public Health (FOPH), the right of option is exercised only once for the entire duration of the cross-border activity, except for a change of circumstances provided for by the regulations (a change of employer or status in particular, to be checked case by case). A cross-border worker who chooses the CMU therefore cannot return to the LAMal simply because of a variation in premiums.
Five criteria make it possible to decide: the real cost according to income, the deductible and out-of-pocket costs, access to care, the family situation, and coverage of loss of income. The following sections put figures on each of them.
Real cost: CHF 60'000, 90'000 and 150'000 of income
A single cross-border worker with a gross annual salary of CHF 90'000 pays in LAMal a premium of roughly CHF 450 to 500 per month in Geneva, with a CHF 300 deductible, i.e. CHF 5'400 to 6'000 per year. Under the CMU, the contribution depends on the French reference taxable income, not on the premium: it is calculated at 8% of the base above an allowance, with a ceiling.
Calculation assumptions for the three scenarios, single adult, LAMal deductible at CHF 2'500 for the low premiums and CHF 300 for the high premiums, reference taxable income close to the net taxable salary converted into euros:
CHF 60'000 of income: LAMal premium of CHF 4'200 to 6'000 per year depending on the deductible. CMU contribution in the order of EUR 2'000 to 2'800, markedly lower. The CMU generally comes out ahead.
CHF 90'000 of income: LAMal premium of CHF 4'200 to 6'000. CMU contribution in the order of EUR 3'600 to 4'400. The gap narrows, the CMU often remains cheaper.
CHF 150'000 of income: LAMal premium unchanged, as it does not depend on income. CMU contribution that approaches or reaches the ceiling, i.e. roughly EUR 6'000 to 7'500. The tipping point lies here: the LAMal becomes cheaper.
These orders of magnitude are indicative. They are based on the cantonal premiums published by the FOPH (https://www.bag.admin.ch/fr/assurance-maladie) for the current year, and on the provisions of the French Social Security Code relating to the health contribution of cross-border workers who have opted for the CMU. Check the exact scale on the date you take out cover: premiums and rates change every year.
Rule of thumb: the LAMal premium is a fixed amount per person, whereas the CMU contribution is proportional to income. The higher the income, the more attractive the LAMal becomes. At CHF 60'000, the CMU generally costs less than half.

Key takeaway
The LAMal premium is fixed per person whereas the CMU contribution follows income: the higher the salary, the more attractive the LAMal becomes, with a tipping point around CHF 150'000.

Deductible, co-payment and out-of-pocket costs: CHF 700 per year
The LAMal co-payment is capped at CHF 700 per year for an adult: this is the maximum threshold of the insured person's share of costs, once the deductible has been absorbed. It amounts to 10% of the cost of services above the deductible.
The deductible is chosen between CHF 300 and CHF 2'500 per year for an adult. The calculation is mechanical:
CHF 300 deductible: higher premium, maximum out-of-pocket cost of CHF 1'000 per year (CHF 300 deductible + CHF 700 co-payment).
CHF 2'500 deductible: lower premium, maximum out-of-pocket cost of CHF 3'200 per year (CHF 2'500 + CHF 700).
The saving on the annual premium between the two levels often reaches CHF 1'000 to 1'500 in Geneva. An insured person who is rarely ill benefits from choosing CHF 2'500. An insured person who consults regularly or is undergoing treatment is better off with the low deductible.
On the French side, the CMU works with a ticket modérateur (patient co-payment): a share of the costs remains payable by the insured person (30% on a doctor's consultation, 20% in hospital, with daily flat-rate charges). There is no overall annual deductible. A French complementary insurance, the mutuelle, generally covers this ticket modérateur. Out-of-pocket costs under the CMU therefore depend on the complementary insurance contract, whereas under the LAMal they are capped by law.
For an insured person with high health expenses, the CHF 700 co-payment cap constitutes a quantified protection that the CMU does not offer in this form.

Key takeaway
The CHF 2'500 deductible reduces the premium by CHF 1'000 to 1'500 per year in Geneva, but raises the maximum out-of-pocket cost from CHF 1'000 to CHF 3'200: it suits those who are rarely ill.
Access to care: providers, alternative models, reimbursements
With the LAMal, a cross-border worker receives care in Switzerland as in France, according to the terms of the policy. Under the CMU, access to care in Switzerland remains possible within the framework of the French reimbursement rules, but Swiss tariffs often exceed the reimbursement bases: out-of-pocket costs rise quickly.
Swiss medical tariffs are markedly higher than in France. A GP consultation costs several times the French tariff in Switzerland. A CMU insured person who consults in Geneva receives a reimbursement calculated on the French basis, hence a significant gap payable by them. A LAMal insured person is reimbursed according to Swiss tariffs.
The LAMal offers alternative insurance models (article 41 LAMal and implementing ordinance) which reduce the premium in exchange for a restriction of choice:
Family doctor: mandatory consultation of the designated doctor before any specialist.
Telemedicine: calling a telephone advice centre before any consultation.
HMO: care provided at a designated health centre.
These models reduce the premium by 10 to 25% depending on the insurer. They suit insured persons who accept a single entry point into the care system.
For a cross-border worker who is mainly treated in France, the CMU offers reimbursement consistent with the place of residence. For a cross-border worker who consults mainly in Geneva, the LAMal avoids tariff gaps. Another point of reference: the LAMal also covers emergency care abroad, but the conditions vary according to the policy.
Family and spouse: dependants change the calculation
Two children and a spouse without employment: four people to insure. Under the LAMal, each has their own premium. Under the CMU, the contribution is based on household income and in principle covers dependants without an additional individual premium.
LAMal premiums for children are markedly lower than those for adults (in the order of CHF 100 to 130 per month in Geneva, depending on the insurer and the deductible). Young adults aged 19 to 25 also benefit from a reduced premium. The child deductible ranges from 0 to CHF 600.
Worked example, family of four, income of CHF 90'000:
LAMal: two adult premiums (approximately CHF 8'400 to 12'000 per year for the two, depending on the deductible) plus two child premiums (approximately CHF 2'400 to 3'100 per year). Total in the order of CHF 10'800 to 15'000 per year.
CMU: a single contribution on the household's reference taxable income, which covers dependants. The order of magnitude remains close to that of a single adult, i.e. EUR 3'600 to 4'400 under this assumption.
For a couple with children, the LAMal therefore generally costs more, sometimes double or more, while the CMU may amount to a fraction. This ratio reverses if household income is very high, as the CMU contribution is capped.
Cases where a broker should redo the calculation: spouse with their own income in France, children in higher education, blended family, or dependants residing in different States. The spouse's income enters the CMU base and can shift the tipping point.
Complementary insurance and loss of earnings: what the LAMal does not
The LAMal pays no replacement income in the event of illness. It is a care insurance, not a loss-of-income insurance. A self-employed person or an SME manager who falls ill for 6 months continues to pay their expenses without any indemnity, unless they have taken out a daily sickness allowance insurance (IJM, indemnité journalière maladie, also called sickness loss-of-earnings cover).
The LCA (Federal Insurance Contract Act) governs complementary insurance and optional IJM. Employees in Switzerland are in principle covered through their employer, who must maintain salary according to the applicable scale (Bernese, Zurich or Basel scale depending on the cantons and the Code of Obligations, art. 324a) or take out a collective IJM. Self-employed persons and managers do not have this safety net by default.
Usual reference points for an individual or collective IJM:
Premium rate: in the order of 0.8% to 1.5% of payroll or insured income, depending on age, sector and waiting period.
Waiting period: 30, 60 or 90 days. The longer it is, the lower the premium.
Coverage: generally 80% of salary for 720 days.
Between two offers at 0.8% and 1.1%, the real difference lies in the waiting period: 30 days versus 60. For an insured income of CHF 120'000, a 0.3-point difference represents CHF 360 per year, but 30 days without indemnity represent roughly CHF 8'000 of uncovered income during the period. These figures are orders of magnitude to be confirmed offer by offer.
On the complementary side, the French mutuelle supplements the CMU, while the Swiss LCA offers complementary insurance (hospitalisation in semi-private or private ward, alternative medicine, dental care). These are subject to a health examination and may exclude pre-existing conditions. Supervision of insurers falls under FINMA (https://www.finma.ch/fr/surveillance/assurances/).

Verdict by profile: four typical situations
No option wins in absolute terms. Each verdict below rests on a quantified assumption and must be rechecked against the scales for the year.
Single employee, CHF 60'000 to 90'000. Assumption: LAMal deductible CHF 2'500, no pathology. The CMU generally works out cheaper at CHF 60'000. At CHF 90'000, the gap narrows: compare the exact LAMal premium with the contribution calculated on your reference taxable income.
Couple with two children, CHF 90'000. Assumption: spouse without employment, four people to insure. The LAMal generally costs more, in the order of CHF 10'800 to 15'000 per year against a single CMU contribution close to that of a single adult. The CMU comes out ahead on this profile, except where household income is very high.
Self-employed person or SME manager, CHF 150'000. Assumption: high income, CMU contribution close to the ceiling. The LAMal often becomes more advantageous on basic cost. But the decisive criterion lies elsewhere: the IJM. Neither the LAMal nor the CMU replaces income in the event of incapacity for work. Budget for an IJM at 0.8% to 1.5% of insured income, with a waiting period of 30, 60 or 90 days depending on your cash position.
Cross-border worker close to retirement or with a chronic condition. Assumption: regular and high health expenses. The CHF 700 co-payment cap and the CHF 300 deductible limit LAMal out-of-pocket costs to CHF 1'000 per year. The CMU, with its ticket modérateur, may cost more depending on the mutuelle. Retirement also changes the applicable scheme: have the situation checked before the deadline.
Cases where an authorised broker should redo the calculation: multiple dependants, chronic condition, spouse's income, retirement plans, self-employed activity. As the right of option is in principle irrevocable, an initial error is paid for throughout the entire period of activity.
