ONVZ Health Insurance for Students in the Netherlands

Disclaimer: The information on this page is intended as a general guide. Premiums, coverage details, and legal obligations depend on current Dutch legislation, the insurer’s policy terms, and your personal employment situation.

ONVZ (Onderlinge Nationale Verzekering tegen Ziekenhuiskosten) is an independent, non-profit health insurer that has been operating in the Netherlands since 1933. Known for its high-quality service and freedom of choice, ONVZ is often a top choice for students who want more control over their healthcare. This guide explains how ONVZ works, the costs for 2026, and the specific rules for international students.

What is ONVZ Health Insurance?

Unlike many large insurance conglomerates, ONVZ remains an independent association without a profit motive. They focus on providing high-quality “restitution” policies, which generally allow for more freedom when choosing your own doctor or hospital. For students, this means less worry about whether a specific clinic is “contracted” or not.

Do You Need Dutch Health Insurance?

One of the most common points of confusion for international students is whether they are legally required to buy a Dutch policy. In the Netherlands, this is determined by your activity, not just your residency.

Study-Only Students vs. Working Students

• Study-Only: If you are an international student and you do not work or have a paid internship that makes you insured under the Wlz scheme, you are generally not allowed to take out a Dutch basic policy like ONVZ. You should rely on your EHIC or private international insurance.

• Working Students: The moment you start paid work, even a part-time job of a few hours, you usually fall under the health insurance rules for working students and must take out a Dutch basic insurance policy. Paid internships require a separate SVB/Wlz check: since 1 September 2025, payment, country group and employee-insurance status matter.

Warning: If you are required to have insurance but fail to register, the CAK (the regulatory body) can issue retroactive fines of several hundred euros. It is vital to assess your status the moment you sign a work contract.

Coverage and Policy Types

ONVZ offers different types of basic insurance (basisverzekering). While the government determines the “Basic Package” content, the way you access care differs between plans.

Vrije Keuze (Restitution) vs. Bewuste Keuze (Natura)

• Vrije Keuze (Restitution): This is ONVZ’s flagship policy. It offers almost complete freedom of choice. You can visit almost any healthcare provider, and ONVZ will reimburse the costs up to the market-level rate.
• Bewuste Keuze (Natura): A more budget-friendly “in-kind” policy. You receive 100% reimbursement when visiting contracted providers, but you may have to pay a portion of the bill if you choose a non-contracted specialist.

What is Covered and Excluded?

• General Practitioner (GP/huisarts) consultations.
• Emergency medical care and hospital stays.
• Prescription medications (standardized list).
• Mental health care (with a referral).

• Adult dental care (requires a supplementary dental module).
• Physiotherapy for most non-chronic injuries (requires a supplementary plan like Startfit).
• Contraception for those aged 21 and older (requires supplementary coverage).

Costs, Deductibles, and Allowances

Budgeting for healthcare involves three main components: your monthly premium, the deductible, and potential government subsidies.

ONVZ Premium Overview (2026)

Below are the indicative monthly premiums for ONVZ in 2026. Note that these are for the basic package with the standard deductible.

The Mandatory Deductible (Eigen Risico)

Almost all Dutch basic policies include a mandatory deductible (eigen risico). For 2026, this is set at **€385**. This means you pay the first €385 for specialized care (like hospital visits or lab tests) each year. Visits to your GP are exempt from this deductible—the Dutch want you to see your doctor when you are sick!

Healthcare Allowance (Zorgtoeslag)

If you are a working student with a low income, you can significantly lower your net costs by applying for the healthcare allowance (zorgtoeslag). In 2026, the maximum allowance is approximately **€129 per month**, which could bring your net insurance cost down to around €33 to €43 per month.

Common Student Scenarios

The Part-Time Worker: Maria is an international student who started working 8 hours a week at a café. She must switch to a Dutch policy. She chooses ONVZ Bewuste Keuze for €156.10. Since she earns a low wage, she receives €129 in zorgtoeslag. Her actual cost is only €27.10 per month.

The Study-Only Student: John is in the Netherlands only for his Master’s degree and does not work. He uses his EHIC card from his home country. He is not allowed to join ONVZ and pays nothing into the Dutch system.

Step-by-Step Plan: Joining ONVZ

1. Verify your obligation: Confirm if your job or paid internship makes Dutch insurance mandatory.
2. Get your BSN: You must be registered at your local municipality to receive your Citizen Service Number (BSN).
3. Compare and Apply: Use our comparison tool to see if ONVZ’s premiums fit your budget, then apply via their website.
4. Apply for Zorgtoeslag: Log in to Mijn Toeslagen on the Belastingdienst website to claim your monthly allowance.
5. Notify if you leave: If you stop working or leave the Netherlands, you must cancel your policy to avoid ongoing bills.
