Hospitalisation insurance: why your health insurance fund is never enough

Single-room supplements, unregulated fees, costs before and after a hospital stay: what your health insurance fund (mutuality) does not cover, what it costs per year, and why the tax treatment is less favourable than for income protection insurance.

Why your health insurance fund is not enough

Your compulsory health insurance fund (statutory health insurance run by the NIHDI, INAMI/RIZIV) reimburses healthcare at agreed rates. For a "standard" stay in a shared room, it covers most of the cost after the patient's co-payment. The problem: as soon as a patient asks for a single room or a non-contracted doctor is involved, the bill shoots up and the fund does not cover the gap.

In practice, a one-week surgical stay in a single room with non-contracted doctors can leave several thousand euros for the patient to pay, of which the health insurance fund reimburses only a fraction. That is exactly the gap private hospitalisation insurance fills.

What hospitalisation insurance covers

A standard hospitalisation policy covers five main categories of cost:

  • Single-room supplements, charged directly by the hospital, typically €50 to €250 a day depending on the hospital.
  • Medical fee supplements: non-contracted doctors can double or triple their fees for single rooms.
  • Pre-hospitalisation costs (1 month before): consultations, tests, lab work, medical imaging.
  • Post-hospitalisation costs (3 to 6 months after): physiotherapy, follow-up consultations, medicines.
  • Medicines and equipment not reimbursed by the NIHDI during the hospital stay.

The best policies also include serious illness cover, which reimburses outpatient treatment (chemotherapy, radiotherapy) without a hospital stay being needed, as well as maternity cover for couples.

Single, couple, family: which plans

Belgian hospitalisation policies typically come in three structures:

  • Single: the self-employed person alone.
  • Couple: the self-employed person and their partner (married or legally cohabiting). Combined pricing is slightly more favourable.
  • Family: couple + dependent children. Children usually get a reduced rate (50% of the adult rate) and stay covered up to age 25 if they are studying.

Indicative annual cost in 2026

Premiums depend heavily on age, the plan (single room or not), the ceilings chosen and the insurer. Benchmarks for 2026 for a non-smoking adult, single-room plan, standard ceilings:

Age 30 · single → ≈ €300 to €450 a year

Age 40 · couple → ≈ €600 to €900 a year

Age 40 · family (2 children) → ≈ €1,000 to €1,500 a year

Age 55 · couple → ≈ €1,200 to €2,000 a year

Indicative Belgian market figures for 2026. The premium rises with age; long-term policies smooth it out.

Why the premium is not deductible

Unlike income protection insurance and professional liability insurance, individual hospitalisation insurance is not regarded as a business expense by FPS Finance: it falls within the personal sphere. This has three important consequences:

  • Taken out as a natural person: the premium is not deductible and does not reduce your personal income tax (IPP/PB) base.
  • Taken out by your SRL/BV: the premium paid by the company for you (as director) is a taxable benefit in kind (BIK) under personal income tax. This rarely works out better than taking out the policy privately.
  • Group insurance plan (salaried employees): a specific regime, partly advantageous for the beneficiary (and deductible for the company), but not applicable to a self-employed director on their own.

See the details in benefits in kind (BIK).

How to choose the right policy

Six criteria matter beyond the headline price:

  1. Overall annual ceiling and per-item ceilings: some policies cap reimbursements at an annual maximum or per claim.
  2. Outpatient serious illness cover: key for cancer, cardiology, neurology.
  3. Maternity cover: if you are thinking of having children, check the waiting period (often 9-12 months).
  4. Pre-existing conditions and waiting periods: which conditions are excluded, and for how long.
  5. Care network: some policies favour partner hospitals (pricing advantages).
  6. Past price changes: an insurer whose premiums have doubled in 5 years signals a risk for the future.

Hospitalisation FAQ

Frequently asked questions about hospitalisation insurance

  • Yes, in most cases. Compulsory health insurance (NIHDI) reimburses part of your care at agreed rates, but does not cover single-room supplements (often €100 to €300 a day), nor the fee supplements of non-contracted doctors (which can double or triple the cost of a procedure). Hospitalisation insurance fills exactly these blind spots.

  • Three items dominate: (1) the single-room supplement, set by each hospital, typically €50 to €250 a day; (2) fee supplements from non-contracted doctors, which can be charged without a cap for single rooms; (3) certain medicines, equipment and outpatient costs not reimbursed by the NIHDI. Hospitalisation policies cover these three items up to set ceilings.

  • Yes, and it is a key part of the cover. Standard policies cover outpatient care linked to the hospital stay for 1 month before admission and 3 to 6 months after discharge: consultations, tests, medicines, post-operative physiotherapy. This cover is essential for serious conditions (cancer, cardiology, orthopaedics).

  • No, unlike income protection insurance and professional liability insurance. An individual hospitalisation insurance premium taken out by a self-employed person as a natural person is not deductible as a business expense. If the premium is paid by your SRL/BV for you as director, it is a benefit in kind (BIK) taxed under personal income tax, and in most cases the financial advantage disappears.

  • A single plan covers only the self-employed person. A couple plan adds the partner (married or legally cohabiting). A family plan includes dependent children. Children can often stay covered up to age 25 if they are still studying. Premiums rise accordingly, but children usually get a reduced rate (often 50% of the adult rate).

  • The Belgian Act of 20 July 2007 protects policyholders: if you switch hospitalisation insurer after more than a year, the new insurer must accept you without a medical questionnaire and without new exclusions, provided there has been no break in your cover. This portability is fundamental: it stops you being stuck with an insurer whose prices drift upwards.

  • The best policies include "serious illness" cover, which reimburses outpatient treatment (chemotherapy, radiotherapy, immunotherapy) without a hospital stay being needed. This cover is becoming critical as more and more heavy treatments are given on an outpatient basis. Check the list of conditions covered and the annual ceilings.

  • Yes, most policies impose a waiting period of 3 to 6 months for planned hospital stays (except accidents, which are covered immediately). Pre-existing conditions are often excluded for the first few years, or even permanently. Read the exclusions section of the general terms and conditions before signing.
