You must choose a health insurance provider within four months of arriving in the Netherlands. This post explains exactly what the law requires you to buy and helps you decide if extra coverage is worth the monthly cost. Understanding the verschil basisverzekering aanvullende verzekering (difference between basic insurance and supplemental insurance) helps you avoid unexpected bills when visiting a doctor or pharmacy. You'll know how to choose a policy that fits your budget without losing access to medical care.
The mandatory Basisverzekering
The basic insurance package is a legal requirement for every person living or working in the Netherlands. You buy this from a private zorgverzekeraar (health insurer), but the government decides what it must cover. You'll pay a monthly premie (premium) which usually falls between 135 and 160 euros depending on the provider and your choices. Under this mandatory policy, visits to your huisarts (GP) are always covered. You don't pay anything out of pocket for a standard consultation with your family doctor. If you're under 18, almost all your medical costs, including dental care, are covered by the basic insurance of your parents for free.
Most adult medical services require you to pay the eigen risico (deductible) first. For 2024 and 2025, the standard amount is 385 euros. This means you pay the first 385 euros of your hospital or specialist costs yourself each year. Note that some services, like the GP and maternity care, are exempt from this deductible. You can choose to increase this amount to 885 euros to lower your monthly premium, but it's risky if you have an accident. This voluntary increase is a common way for healthy people to save 15 to 20 euros every month on their bills.
There are two main types of basic policies you should recognize: naturapolis (in-kind policy) and restitutiepolis (reimbursement policy). With a naturapolis, the insurer pays the hospital directly, but only if they have a contract with that specific provider. If you go to a non-contracted hospital, you might pay 20% to 30% of the bill yourself. A restitutiepolis gives you freedom to choose any provider. It usually costs more per month, but the insurer pays the full bill regardless of contracts.
When to add an 'Aanvullende' package
The aanvullende verzekering (supplemental insurance) is entirely optional. Insurers use these packages to cover things the government leaves out of the basic plan. Unlike the basic policy, an insurer can refuse to give you a supplemental package based on your health history, though it's rare for simple plans. Most people use these for physical therapy, glasses, or birth control. You'll find that these packages are sold in tiers, ranging from a few euros to over 50 euros per month.
Dental care for adults (Tandarts)
Once you turn 18, the basic insurance stops covering regular dental cleanings, fillings, and check-ups. You must pay for these uit eigen zak (out of your own pocket) unless you buy a dental supplement. A standard check-up at the tandarts (dentist) costs around 25 euros, but a filling can easily reach 80 euros. If you only visit the dentist twice a year for a cleaning, paying for the extra insurance often costs more than the bill itself.
However, if you know you need a root canal or several fillings, a dental plan is useful. Most dental supplements have a maximum payout, such as 250 or 500 euros per year. They also often cover only 75% of each bill. For simple dental needs, saving 15 euros a month in a personal bank account is often smarter than buying insurance. This way you keep the money if your teeth remain healthy.
Alternative medicine and orthodontics
Many residents seek treatments like acupuncture, chiropractic care, or specialized therapy. The basic insurance never pays for these alternative treatments. If you use these services regularly, look for a package that offers a daily allowance, often capped at 40 or 50 euros per visit. These packages frequently have a total annual limit of 300 to 500 euros.
Orthodontics for children is another major reason parents buy supplemental insurance. Braces for a teenager can cost between 2,000 and 3,000 euros over several years. Since the basic plan doesn't cover this, many families start a supplemental plan a year before the treatment begins. Be aware that many insurers have a wachttijd (waiting period) of one year for orthodontics. You must pay for the insurance for 12 months before you can claim any costs for the braces. This rule prevents people from signing up only when they see a big bill coming.
Global emergency coverage
Your basic Dutch insurance covers emergency medical care anywhere in the world, but only up to Dutch price levels. If you visit a country where healthcare is much more expensive than in the Netherlands, like the United States or Switzerland, you face a financial risk. If the foreign hospital charges triple that amount, you must pay the difference yourself.
A supplemental buitenland (abroad) package covers these price gaps. Many travelers choose this to avoid the high costs of private clinics in holiday destinations. It often includes repatriëring (repatriation), which is the cost of flying you back to the Netherlands in a specialized medical plane. If you already have a separate travel insurance policy, check if it covers medical costs to avoid paying for the same thing twice. You don't want to double your costs for the same protection.
The 'Overstappen' process in December
You can only change your health insurance once a year. Your current insurer will send you a new proposal for the upcoming year in mid-November. You then have until December 31st to cancel your old policy. Once you cancel, you have until the end of January to pick a new one, but the new policy will start retroactively from January 1st.
Using a vergelijker (comparison website) is the fastest way to save money. Sites like Independer or Zorgkiezer let you enter your needs and show you a list of the cheapest providers. You'll need to decide if you want to stay with the same zorgverzekeraar or switch to a new one. Switching is simple because your new company will cancel your old contract for you automatically. Most people can save over 100 euros per year just by spending 20 minutes on these websites.
If your income is below a certain level, you can apply for zorgtoeslag (healthcare allowance) from the Belastingdienst (Tax Office). This monthly subsidy helps you pay for the basic insurance premium. You must apply for this yourself through the Mijn Toeslagen (My Allowances) portal using your DigiD. Many students and low-income workers find that the zorgtoeslag covers a large portion of their monthly insurance bill. Even if you switch insurers, your eligibility for the allowance stays the same. You should check the income limits every year as they change.
Bottom line
The basic insurance covers essential medical care like the GP and hospitals, while supplemental packages are optional extras for things like dentists and glasses. You should only buy extra coverage if your expected medical costs for the year are higher than the total annual premium of the supplement. Reviewing your previous year's medical bills is the best way to determine if you'll save money by switching to a more expensive package.
