Health insurance fund in Belgium 2026: choosing and understanding reimbursements
A two-tier INAMI/RIZIV system, five families of health insurance funds, medical conventioning, patient co-payment, GMD/DMG, hospitalisation insurance: Belgian healthcare is reputed to be excellent but labyrinthine. We untangle what really matters to you in 2026.
In Belgium, health is a federal competence. Whether you live in Brussels, Liège, Antwerp or Eupen, you contribute to the same INAMI/RIZIV system, you access the same nomenclature of reimbursed care and you benefit from the same protection ceilings. The communities mainly manage prevention and certain services for the elderly and disabled, but the heart of the system — compulsory health insurance and reimbursements — is the same everywhere.
This guide gives the overview to choose your health insurance fund with full knowledge and understand how you will be reimbursed. For aids specific to modest incomes (BIM/RVV status, MAF/MAB, special solidarity funds), read our dedicated pillar on BIM, MAF and health aids.
The Belgian system in two tiers
The Belgian health social security works on a double tier. This is essential to understand before choosing a fund.
This is the national health insurance. You contribute to it automatically via your social contributions (ONSS/RSZ for employees, INASTI/RSVZ for the self-employed). It reimburses care according to a single nomenclature: medical consultations, hospitalisations, medication, physiotherapy, dentistry, ophthalmology, etc.
The reimbursement rates are identical across all funds. A consultation with a conventioned GP is reimbursed the same at Partenamut, at the Christian fund (MC/CM), at Solidaris or at the CAAMI/HZIV.
This is what differentiates the funds from one another. Each fund organises its own mandatory supplementary insurance, financed by a modest contribution (~€12 to €15/month in 2026). It finances additional reimbursements and services that INAMI/RIZIV does not cover.
Dental care not reimbursed by INAMI/RIZIV, glasses, additional physiotherapy, convalescence stays, travel vaccines, contraception, prevention: it is in this part that the funds really distinguish themselves.
To this is added an optional 3rd layer: private hospitalisation insurance, which can be taken out with your fund or with a private insurer (DKV, AG Insurance, AXA, Ethias…) to cover the risk of a single room or fee supplements. We come back to it further on.
The five families of Belgian health insurance funds
The Belgian landscape is historical: five large national unions bring together all the funds. Each has its sensitivity, its network and its specificities.
| Family | Main players | Historical sensitivity |
|---|---|---|
| Christian fund (MC/CM) | MC in Wallonia/Brussels, CM in Flanders | Catholic origin, largest Belgian fund in number of members |
| Solidaris (socialist) | Solidaris Wallonie, Solidaris Brabant, Bond Moyson | Socialist origin, active campaigning on health policies |
| Liberal fund (ML) | Liberal Mutuality (Mutualité Libérale) | Smallest of the three "political" funds |
| Neutral funds | Neutral Mutuality, UNMN-LNZ | Without political affiliation, autonomous |
| Independent funds | Partenamut, Helan, Solidaris Indépendant, OZ, Securex Mutuality | Independent from the historical pillars, private management |
There is also the CAAMI/HZIV (Auxiliary Fund for Sickness and Disability Insurance), a public body that serves as a replacement fund. It offers only the compulsory health insurance (tier 1) — no supplementary insurance or additional benefits. Minimal contribution, minimal reimbursements. A relevant choice only if you have no use for the supplementary services.
How to choose your health insurance fund?
Since the basic reimbursement is identical everywhere, the choice comes down to four concrete dimensions:
You are not married to your fund for life. You can change every quarter, without justification, and the new fund handles the administrative steps free of charge. If your current fund's supplementary insurance no longer suits you (or if you have discovered that another one reimburses better the care you use), don't hesitate to compare.
Medical conventioning — the key to reimbursement
This is probably the most misunderstood concept of the Belgian system — and the one that can vary your bill from single to triple.
In Belgium, doctors (and other providers) can be conventioned, partially conventioned or non-conventioned. This says nothing about their competence — it is solely a matter of rates.
The practitioner applies strictly the INAMI/RIZIV rates. The fund's reimbursement is calculated on this rate, and there is no supplement. This is the most protective case for your wallet.
The practitioner applies the INAMI/RIZIV rates during certain time slots/days, and free rates elsewhere. They must clearly display their conventioned slots.
The practitioner sets their rates freely. You can pay €60, €80, €100 for a consultation with a specialist. The INAMI/RIZIV reimbursement remains calculated on the official rate — the difference remains your responsibility.
To check a doctor's status before an appointment: doctena.be, the fund's website, or simply ask the practice. The official pictogram must be displayed in the waiting room.
Many hospital specialists are non-conventioned or partially, especially in university and private hospitals. A consultation can cost €80 to €150 with an INAMI/RIZIV reimbursement calculated on ~€30. Before making an appointment with a specialist, systematically ask for the rate and the conventioning status.
The patient co-payment — what remains your responsibility
The patient co-payment (ticket modérateur/remgeld) is the share of healthcare that remains your responsibility after the intervention of INAMI/RIZIV. It is what determines what you really pay in the end.
For an ordinary insured person in 2026, here are the orders of magnitude:
| Care | Co-payment without GMD/DMG | Co-payment with GMD/DMG / BIM |
|---|---|---|
| Consultation with a conventioned GP | ~€6 | ~€4 (GMD/DMG) / ~€1 (BIM with GMD/DMG) |
| Consultation with a conventioned specialist (cardiologist, etc.) | ~€12 depending on specialty | ~€3 (BIM) |
| Home visit | ~€10–13 | ~€3 (BIM) |
| Category A medication (vital) | €0 | €0 |
| Category B medication | ~25% of the price | ~15% (BIM) |
| Hospitalisation 1 day (shared room) | ~€45 + possible supplements | ~€5 (BIM) |
These co-payments accumulate over the year — this is what serves to calculate the Maximum Billing (MAF/MAB), a protection ceiling beyond which your fund fully reimburses the rest. More details in our BIM and MAF pillar.
The GMD/DMG (Global Medical Record) — the most profitable lever
The GMD/DMG is a simple, free, and scandalously underused mechanism. It consists of centralising your medical record with your general practitioner, and gives you the right to an increased reimbursement of 100% for consultations with this doctor.
How to open it? At your next consultation, simply ask your GP: "I would like to open a GMD/DMG". They take care of everything. If you don't have a treating doctor, you can choose any GP — there is no obligation of prior registration as in some countries.
Hospitalisation insurance — useful or not?
Private hospitalisation insurance (tier 3) covers what INAMI/RIZIV and your fund do not cover in case of hospitalisation. It is the best-selling health insurance product in Belgium, but also the one where you need to be the most careful.
What a typical hospitalisation insurance covers:
Daily supplement of €50 to €250 depending on the hospital. Without insurance, fully your responsibility. This is the most costly item.
Non-conventioned doctors in hospital, particularly in a single room. Can reach 100 to 300% of the INAMI/RIZIV rate.
Pre-operative consultations, examinations, post-hospitalisation care for a defined period (1–3 months after discharge).
Depending on the contracts, in addition to or instead of the European Health Insurance Card.
Fund or private insurer?
The funds offer hospitalisation insurance at moderate prices (often €100 to €250/year for an adult under 50), with guaranteed admission without a medical questionnaire. Longer waiting period, sometimes more modest guarantees.
The private insurers (DKV, AG, AXA, Ethias…) offer broader coverage (unlimited supplements, systematic single room), but with a medical questionnaire, exclusions of pre-existing illnesses, and higher rates (€300 to €800/year depending on age and formula).
1. Subscribing too late: the exclusions for pre-existing illnesses can cut off your access. 2. Choosing a mini formula without looking at the exclusions (cosmetic surgery, risky sports, suicide during the first months). 3. Stacking 2 hospitalisation insurances (employer + personal) without realising that this creates reimbursement conflicts and never reimburses you 200%.
