Complaints About Your Health Insurance: A Step-by-Step Guide

Disclaimer: The information on this page serves as a general guide to resolving disputes with Dutch health insurers. It does not constitute personal legal or financial advice. Procedures and administrative fees are regulated by the government and independent authorities.

Dealing with a denied medical claim or poor customer service in a foreign country can be highly stressful, especially on a student budget. Fortunately, the Dutch healthcare system offers strong, accessible consumer protections. Whether you are disputing a rejected reimbursement, a premium issue, or a problem with your basic insurance coverage, this step-by-step guide will help you claim your rights.

Step 1: The Internal Complaints Procedure

Before you can seek external help, Dutch law requires you to formally file a complaint with your health insurance company. Every insurer has a dedicated complaints department.

• File digitally: Most insurers have an online portal, app, or specific complaint form on their website where you can submit your issue directly.
• Be specific: Always include your policy number, the date of the medical treatment, and a clear reason why you disagree with their decision.
• Response time: By law, the insurance company must respond to your formal complaint within a reasonable timeframe (usually 4 to 6 weeks).

Step 2: Mediation by the SKGZ (Ombudsman)

If you and your insurer cannot reach an agreement, your next step is the Stichting Klachten en Geschillen Zorgverzekeringen (SKGZ) (Complaints and Disputes Health Insurance Foundation). This is an independent, impartial Dutch organization designed to mediate problems between individuals and insurers.

First, the Ombudsman will review your case. The Ombudsman acts as a mediator to find a mutually acceptable solution. This mediation process is completely free of charge for you. Historically, about 50% of all cases are successfully resolved at this stage without needing further legal action.

Visit the SKGZ website to submit your case for mediation.

Step 3: The Health Insurance Disputes Committee

If mediation by the Ombudsman fails, you can escalate your complaint to the Geschillencommissie Zorgverzekeringen (Health Insurance Disputes Committee). This is a more formal step that results in a binding decision. This means both you and the insurance company are legally obligated to follow the committee’s ruling.

• Costs: Starting a dispute requires a small administration fee (currently €37 in 2026). If the committee rules in your favor, this fee will be fully refunded to you.
• Procedure: The committee will thoroughly examine the evidence, the Dutch healthcare laws, and your policy conditions before making their final decision.

The Dutch Healthcare Authority (NZa)

The Nederlandse Zorgautoriteit (NZa) is the market regulator for healthcare in the Netherlands. While they do not mediate individual disputes between you and your insurer, you can report structural issues or unfair practices to them. Your report helps the NZa monitor the market and intervene if an insurer is systematically breaking the rules.

Report an issue to the NZa.

Common Complaints from International Students

International students often face specific administrative hurdles. Are you experiencing one of these?

• Unjustified CAK Fines: If you are a study-only student with an EHIC and received a fine from the CAK for being uninsured, do not complain to a health insurer. You must file an objection with the CAK and request a Wlz assessment from the SVB.
• Mental Health (GGZ) Rejections: A very common dispute is the rejection of psychological care costs. Remember that Dutch basic insurance only covers this if you have an official referral from your General Practitioner (GP/huisarts) beforehand.
• Emergency Care Abroad: If you required emergency care outside the Netherlands and your insurer refuses to pay the full bill, check if they are applying the Dutch market rate rule (which is standard for basic policies).

If you are fundamentally dissatisfied with how your health insurer treats you, remember that you have the power to leave. Take a moment to compare Dutch health insurers so you can switch to a provider with better customer service during the annual switching period.
