Belgium – Health Insurance

Is health insurance mandatory for expats in Belgium?

Anyone living or working in Belgium is legally required to hold health insurance. Under the Law of July 14, 1994, health insurance is compulsory for anyone present in Belgium beyond a short tourist visit. This obligation applies equally to employees, the self-employed, students, retirees, and non-working residents.

Every resident over the age of 25 with a registered address in Belgium must maintain valid health insurance — and this includes expats. Those over 25 are required to enrol with a public health insurance fund and pay social security contributions in order to gain access to state healthcare services.

Non-EU/EEA nationals must demonstrate proof of health insurance when submitting a visa application. Citizens of third countries are generally required to show coverage of at least €30,000 to obtain a Schengen visa, after which they must integrate into the Belgian healthcare system once they have settled.

New arrivals have exactly 90 days from the date of arrival to register for health insurance. Non-compliance can lead to fines of up to €2,500. It is worth noting that self-employed expats are responsible for arranging and paying their own social contributions, whereas for employees, social payments are typically calculated and deducted directly from salary by the employer.

EU, EEA, and Swiss nationals on short visits to Belgium can use their European Health Insurance Card (EHIC) to access certain healthcare services. However, the EHIC does not provide comprehensive cover, and for anyone intending to live and work in Belgium, it cannot serve as a substitute for enrolment in the public healthcare system.

How does the public health system in Belgium work?

Belgium’s healthcare system is grounded in a social health insurance model, funded primarily through mandatory contributions and taxation. Its goal is to provide universal coverage for all residents. Unlike the UK’s NHS — where care is largely free at the point of use — or a fully privatised model, Belgium follows a reimbursement-based approach similar to France’s Assurance Maladie: patients pay upfront for treatment and then reclaim a substantial portion of the cost from their insurance fund.

The system comprises two main components: mandatory social health insurance (the public element), administered by INAMI/RIZIV and delivered through a mixture of public and private providers — many doctors operate within both sectors. The National Institute for Health and Disability Insurance (NIHDI/RIZIV/INAMI) sets the reimbursement rules, accredits providers, and channels funding to the health insurance funds.

Responsibility for health policy and regulation in Belgium is shared between federal and regional authorities. The Federal Public Service (FPS) Health shapes national policy, oversees social health insurance, regulates the medical professions, and monitors hospital budgets and healthcare standards. Regional and community governments, meanwhile, organise and deliver primary care, mental health services, elderly care, disease prevention, and health promotion programmes.

Day-to-day administration of the system is carried out by mutual insurance funds (mutualités/mutualiteiten) or by a public auxiliary fund. Belgium has two main categories of fund: private mutual insurance funds, which are grouped into five national unions with regional branches — including Solidaris (socialist), Partenamut (independent), CM (Christian), Mutualité Libérale (liberal), and Mutualité neutre (neutral) — and the public auxiliary fund, CAAMI (Caisse Auxiliaire d’Assurance Maladie-Invalidité)/HZIV, which is free to join.

Your choice of fund has no bearing on the reimbursements you receive under compulsory insurance, because all rates are set centrally by INAMI/RIZIV and apply equally to everyone. Funds differentiate themselves through the supplementary insurance they offer, the services they provide, and, in some cases, their philosophical or political orientation.

Belgium’s health system operates on a fee-for-service basis: you attend a healthcare provider, pay for the services received, and are then reimbursed by your insurance fund — typically around 75% of the total. In certain situations, a third-party payment arrangement applies, under which you pay only your share directly to the provider and the fund settles the remainder on your behalf.

How do expats register for public health coverage in Belgium?

Enrolling in Belgium’s public health coverage system involves a sequence of steps across several public bodies. The entire process can span several weeks, so getting started as soon as possible after arrival is strongly advised. Always consult the official socialsecurity.be portal and the INAMI/RIZIV website for up-to-date requirements, as procedures can differ by region and individual circumstances.

1. Register with your local commune (municipality). Your first task after arriving in Belgium is to register with the commune where you are living. This should be done within eight days of arrival. You will need to present your passport or identity card, your residence permit or visa, and proof of your address (such as a lease agreement, accommodation certificate, or utility bill). Following a residential check by a neighbourhood officer, the commune will issue you a National Register Number (RRN/NRN).
2. Register with social security. Employees do not need to take action here — your employer will register you with the ONSS (National Social Security Office) automatically once you provide your National Registration Number. If you are freelance or self-employed, however, you must register with a social security fund independently.
3. Choose a mutual insurance fund (mutuelle/ziekenfonds). Select a fund that suits your personal needs, family circumstances, and desired level of service. The INAMI/RIZIV website lists all funds operating in your area. Several funds have dedicated expat services and multilingual staff, which can simplify the registration process considerably.
4. Submit your registration documents to the fund. You will generally need to provide your National Register Number, a copy of your residence permit, evidence of employment or contribution payments, and your bank account details. Some funds now offer online registration, while others ask you to visit a branch in person.
5. Receive your temporary certificate and ISI+ card. Upon completing your registration, your mutuality will immediately issue a temporary certificate of membership, which can be used to access emergency care while you wait for your permanent card. Your ISI+ insurance card will arrive by post in the weeks following registration.
6. Register a GP and create your Global Medical File (GMD/DMG). Arrange for your GP to open or maintain your Global Medical File (DMG/GMD), which formally links you to a single doctor and entitles you to higher reimbursement rates on consultations.
7. Check your eligibility for reimbursements. Many funds apply a waiting period of up to six months before reimbursing certain treatments, during which time they verify your contribution history. If you can provide evidence of prior social security payments from another country, this period may be shortened or waived — contact your fund and INAMI/RIZIV directly to clarify your position.

For expats, the online tool “Coming2Belgium” allows you to check your social rights based on your nationality, status (employee, self-employed, retiree, student, etc.) and the bilateral agreements between Belgium and your country of origin.

What costs are involved in the public health system in Belgium?

Public health insurance in Belgium is free for residents under the age of 26. Those older than 26 contribute to mandatory insurance through a combination of taxes, social security payments, and membership fees. The figures below reflect the position as of 2025 — always confirm current rates with your fund or on the official INAMI/RIZIV website, since contributions are subject to periodic review.

Employed individuals contribute 13.07% of their gross monthly salary toward social security. This is deducted automatically from payroll, so no separate action is required. Employers add a further contribution of approximately 27% on top of this. Together, these payments fund not only health insurance but also pensions, unemployment benefits, and other social protections.

In 2025, the employee health contribution stood at 4.7% of gross monthly salary, while self-employed individuals must pay at least €871.71 per quarter. Health insurance funds also levy an annual membership fee determined by the government — €64 in 2025, with a reduced rate of €32 for eligible individuals.

Non-working residents, such as students who are not in employment, are not liable for social security contributions but must still register with a health insurance fund and pay a quarterly legal contribution. The precise amount is calculated according to taxable income in Belgium or abroad and ranges from €0 to €785.10 per quarter (rates subject to change — verify with the relevant fund).

Co-payments at the point of care are also part of the system. A consultation with an accredited GP is officially rated at approximately €27–30. The health insurance fund reimburses around 75% of the reference rate, leaving the patient typically paying less than €6 for a standard consultation, or even less for those with preferential status (e.g. people on low incomes or receiving certain allowances). Always verify current tariffs with INAMI/RIZIV or your chosen fund.

What does public health cover in Belgium include and exclude?

Everyone living in Belgium must take out this insurance as soon as they move or begin working in the country. Compulsory insurance covers a substantial proportion of healthcare costs, including GP visits, hospitalisation, and a range of other medical services. Benefits such as sickness pay, incapacity allowances, and maternity payments are also included.

In practice, the public system covers a broad basket of care. All funds offer the same mandatory coverage base — consultations, hospitalisation, essential medicines, basic dental care, maternity services, and more — since this framework is defined at federal level. Prescription medicines are reimbursed at varying rates: essential drugs attract reimbursement of 75–100%, while less critical medications are covered at lower rates.

Mental health care is also supported within the system. Regions and communities are responsible for organising mental health facilities, elderly care, prevention services, and health promotion activities. Referrals to psychologists have been partially reimbursed under an arrangement introduced in recent years, although the extent of coverage varies — check with your fund for the current terms.

Specialist care does not require a formal referral, but there are financial consequences to seeing a specialist without one. You may visit any doctor or specialist in Belgium directly, but doing so without a GP referral will result in lower reimbursement rates and higher out-of-pocket costs. For example, a specialist consultation made with a GP referral typically costs the patient around €12, whereas without a referral the cost can rise to €20–30.

There are notable exclusions from public cover. Belgian public health insurance does not extend to cosmetic procedures, most adult dental treatment beyond basic extractions, or certain alternative therapies. Over-the-counter medicines must be paid for in full, and some prescription drugs are only partially reimbursed — sometimes as little as 20% — depending on the medicine’s classification. Hospital accommodation supplements for private or semi-private rooms also fall to the patient. If hospitalised, you pay a fixed amount for your stay, but the cost of treatment itself is met by your insurer. Choosing a single-occupancy room will attract additional charges.

The fee your doctor charges depends on whether they apply the official regulated rate (prix conventionné). Some healthcare providers charge above this rate, but they are obliged to inform you of this in advance. Reimbursement is calculated only on the standard official tariff — any excess charged above that is not covered by compulsory insurance.

What are the advantages of international private health insurance for expats in Belgium?

Public insurers in Belgium generally cover around 70% of medical expenses. To achieve full coverage, most residents choose to add voluntary insurance. These supplementary options are available both through the mutualities and through private insurers, and many expats opt for an international health policy to meet their needs.

Voluntary private insurance can bring reimbursement up to 100% of costs — or provide direct payment to providers — depending on the level of cover chosen. It also typically grants access to private specialist appointments, which often involve considerably shorter waiting times than those encountered in the public system.

Private health insurance is particularly valuable for expats who travel frequently, as many international plans include global healthcare access, medical evacuation cover, and multilingual customer support. This last feature is especially relevant in Belgium, where medical records, prescriptions, and diagnoses are issued in Dutch, French, or German depending on the region.

Supplementary private cover commonly addresses gaps left by the public system, such as dental treatment, optical care, and private hospital stays. The extent to which these necessities are considered standard is reflected in the statistics: in 2024, roughly 80% of the Belgian population held hospitalisation insurance, 15% had ambulatory insurance, and 19% had dental insurance.

Some employers include private health insurance as part of their benefits package, covering premiums in full or in part. Flexible individual plans are also available for those outside conventional employment. If your employer does not offer a group scheme, arranging an individual international health plan before relocating to Belgium is a prudent step.

How do international private health insurance plans work in Belgium?

Expats in Belgium can choose between purchasing an international health plan from a global provider or taking out insurance directly from a Belgian private insurer. The best option depends on how long you intend to stay, whether you require worldwide portability, and how much additional cover you need beyond the public system.

Local Belgian supplementary plans — offered by the mutualities themselves — are structured to complement public coverage by topping up co-payments, dental costs, and hospital room charges. Beyond these supplementary policies, private mutual insurers also offer optional health products, including dental insurance, hospitalisation cover, and outpatient care insurance. These optional plans can be taken out alongside your main mutuality contract or independently with a different fund or private insurer.

International expat health plans from providers such as Cigna Global, AXA, Allianz Care, and April International go a step further by offering portable, worldwide coverage. These comprehensive plans are well suited to expats who need global healthcare access or specialised treatment, including repatriation and medical evacuation. Many providers tailor their products specifically for expatriates, with direct billing arrangements and multilingual customer service teams.

When assessing plans, it is worth considering several key dimensions:

• Inpatient vs outpatient cover: Inpatient (hospital) coverage is typically included across all tiers; outpatient cover for GP and specialist visits may only be available at a higher plan level.
• Pre-existing conditions: Private insurers in Belgium take varying approaches to pre-existing conditions — some impose waiting periods or higher premiums, while others may exclude these conditions entirely. Clarify the terms before committing to any policy.
• Geographic coverage limits: Establish whether the plan covers treatment throughout the EU, globally, or only within Belgium.
• Repatriation: Many international expat policies cover the full costs of medical transport back to your home country in the event of a serious accident or illness — confirm this is included before purchasing.

Private insurers operating in Belgium must comply with Belgian and EU insurance regulations. If a plan is sold by a foreign insurer, verify that it is authorised to operate in Belgium and satisfies any requirements set by Belgian immigration authorities for visa or residency documentation purposes.

What should expats watch out for with health insurance in Belgium?

Belgium’s health insurance framework is thorough, but it contains several features that frequently take new arrivals by surprise. Understanding these in advance can help you avoid unexpected expenses.

The six-month waiting period for reimbursements. Registering with Belgium’s public health insurance system takes time, and you typically need around six months of social security contributions and compulsory insurance payments before you become eligible to claim reimbursements. During this period, a private healthcare plan is often necessary to cover any treatment you might require. Bridging expat insurance is the most widely used solution for this gap.

The difference between travel insurance and health insurance. Travel insurance is intended for short trips and generally lacks the depth of coverage needed for everyday medical care as a resident. Expat health insurance — sometimes referred to as “incoming insurance” — is a purpose-built solution for the first five years in Belgium, designed to meet both visa requirements and ongoing healthcare needs.

Non-conventional doctors and extra charges. If your doctor operates outside the official tariff system (non-conventioned), you will face a higher out-of-pocket cost, since reimbursement is calculated only on the standard rate. It is wise to confirm whether your doctor or specialist charges the regulated fee before starting any course of treatment.

Pre-existing conditions and private supplementary cover. Belgian public insurance covers all conditions without exclusion for pre-existing health issues. Private supplementary policies, however, may impose waiting periods of 6–12 months for such conditions, or exclude them entirely. Read the policy documents with care before signing up.

Language barriers in documentation. Medical reports, prescriptions, and insurance correspondence in Belgium are issued in Dutch, French, or German according to the region. When comparing expat insurance plans, look for one that covers translation services — this is a practical benefit that can make a significant difference in day-to-day healthcare management.

Registration deadlines and fines. The 90-day registration window is firm. Missing it not only risks a fine but can also extend the period before reimbursements begin. Commence the commune registration process on or shortly after arrival, as securing your National Register Number is the essential first step for everything that follows.

Dependent family members. Your spouse and dependent children can be enrolled as co-insured members under your Belgian mutuelle, provided they are not paying their own social security contributions. Children are generally covered at no additional cost until the age of 25, so long as they remain students or dependants. A non-working spouse can be added as a dependent if they have no independent employment-based coverage. Register dependants at the same time as your own enrolment to avoid delays.

Frequently asked questions: health insurance in Belgium

Can I use my home country’s health insurance in Belgium?

EU/EEA citizens relocating to Belgium who remain covered by their home country’s health insurance may use the European Health Insurance Card (EHIC) for a transitional period. Once they become legal residents in Belgium, however, they are obliged to register with the Belgian health insurance system. Belgium maintains bilateral agreements with more than 20 non-EU countries, including Canada, Australia, the USA, and Japan. These agreements generally guarantee short-term visitors comparable access to healthcare as Belgian residents, but they do not replace full system registration for those settling in the country long-term.

Do I need private health insurance if I have a work contract in Belgium?

Employees in Belgium are automatically enrolled in national health insurance once their employer begins paying social contributions on their behalf. That said, many working expats still choose to take out private insurance to cover the areas the public system does not fully address. Since public reimbursement typically covers only 60–75% of costs, a supplementary plan for dental, optical, and hospitalisation top-up cover is a practical choice for most.

How long does it take to become eligible for public healthcare reimbursements?

It can take up to six months for public insurance to begin reimbursing healthcare costs in full. This waiting period allows the fund to confirm that social security contributions have been regularly paid. If you can demonstrate prior contributions from another country — for example, via an S1 form for EU citizens — the waiting period may be reduced. Contact your chosen fund and INAMI/RIZIV directly for guidance on your particular circumstances.

What is a mutuelle or ziekenfonds?

A mutuelle/ziekenfonds is a mutual insurance fund — the organisation you join in order to have your healthcare costs reimbursed. Your choice of fund has no effect on the reimbursements you receive under compulsory insurance, because all rates are set by INAMI/RIZIV and are uniform across all funds. Where funds differ is in their supplementary products, languages of support, and membership fees.

Are dental and optical costs covered by Belgian public health insurance?

The Belgian healthcare system does cover basic dental care, including routine check-ups and standard treatments. However, most dental procedures for adults that go beyond basic extractions fall outside public coverage. Optical care — including glasses and contact lenses — is also generally not reimbursed under the compulsory system. Both areas are commonly included in supplementary or private insurance plans.

What happens if I need emergency care before I am fully registered?

If you require emergency treatment before your ISI+ card arrives, you can present the temporary certificate of membership issued immediately upon registration with your mutuality. If you have not yet registered at all, emergency care will still be provided, but you may be liable for the full cost without any cover in place. This is why arranging bridging insurance from the moment you arrive in Belgium is strongly advisable.

Can self-employed expats access the same public coverage as employees?

Yes — self-employed individuals in Belgium must register and make contributions independently. They typically pay a higher proportion of their income in social security contributions than salaried employees, with the exact percentage determined by their earnings. Once contributions are up to date and the waiting period has passed, self-employed residents are entitled to the same standard basket of public healthcare coverage as employees.

Is there a maximum cap on out-of-pocket health expenses in Belgium?

Yes — Belgium operates a maximum billing scheme (maximum à facturer / maximumfactuur) that places an annual ceiling on the co-payments any household is required to make, calibrated according to household income. Once this threshold is reached, all further eligible care during that year is reimbursed in full by the public fund. The applicable income thresholds and caps are reviewed each year; consult the INAMI/RIZIV website for the figures currently in force.
