Zilveren Kruis vs CZ for Expats: Health Insurance (2026)

Having now been through both insurers properly — not just as a newcomer who signed up quickly to tick a box, but as someone who actually made claims, contacted customer service, used the apps, and scrutinised dental reimbursements line by line — I feel qualified to compare them honestly for other expats.

This is not a generic overview. I will give you real 2026 premium figures, specific policy differences, and a clear opinion on who should choose which.

Quick Verdict

Choose Zilveren Kruis if:

• You want the most established, widely recognised insurer in the Netherlands
• English-language customer service matters to you
• You want a restitutie (reimbursement) policy with maximum flexibility on providers
• You are based in a major city and want broad specialist access

Choose CZ if:

• You want a slightly lower base premium on natura policies
• You are in the south of the Netherlands, where CZ’s network is historically strongest
• You prioritise physiotherapy coverage in the supplementary package
• You want a no-frills, reliable option without paying for extras you will not use

Neither is dramatically better than the other for basic coverage. The Dutch basisverzekering is regulated by the government, so the core package is identical regardless of which insurer you choose. Where they differ is in price, supplementary add-ons, network size, and how easy they are to deal with when things go wrong.

Understanding Dutch Health Insurance: The Basics for Expats

If you are new to the system, a quick primer. The Dutch healthcare system is built on three layers:

1. Basisverzekering (basic insurance) This is mandatory for everyone living or working in the Netherlands. It covers GP visits, hospital care, most specialist consultations, maternity care, mental health, and a range of medications. The government defines exactly what is covered — every insurer offers the same core package. What differs is the premium, the type of policy (see below), and the contracted care network.

2. Aanvullende verzekering (supplementary insurance) Optional add-ons for things not covered by the basic package: dental care for adults, physiotherapy beyond the covered sessions, glasses, alternative medicine, and more. This is where Zilveren Kruis and CZ differ significantly.

3. Eigen risico (own risk / deductible) In 2026, the mandatory eigen risico is EUR 385 per year. This means the first EUR 385 of your eligible healthcare costs each year comes out of your pocket before your insurer pays. You can voluntarily increase this to EUR 485, 585, 685, 785, or 885 in exchange for a lower monthly premium — but only make that trade-off if you are genuinely healthy and rarely use healthcare. GP visits and maternity care are completely exempt from the eigen risico, which is worth knowing.

Comparison Table: Zilveren Kruis vs CZ at a Glance (2026)

Premiums are approximate for 2026 and vary by specific policy and voluntary eigen risico choice.

Basisverzekering Compared: Policy Types

Both Zilveren Kruis and CZ offer three main types of basic policy. Understanding these is critical because they affect which doctors and hospitals you can use — and how much you pay if you go outside the network.

Natura Policy

With a natura (in-kind) policy, your insurer has contracts with specific healthcare providers. You must use contracted providers to get full reimbursement. If you go to a non-contracted provider, you will only be reimbursed at a lower rate — typically 75-80% of the contracted rate, which can leave you with a significant bill for anything expensive.

• Zilveren Kruis natura: ~EUR 142/month. Large contracted network including most major hospitals. Good for people who are happy to stay within a wide network.
• CZ natura: ~EUR 140/month. Slightly cheaper. Strong network in Zeeland, Noord-Brabant, and Limburg. In Randstad cities (Amsterdam, Rotterdam, The Hague, Utrecht), the network is still solid but historically a touch smaller.

Combinatie (Combination) Policy

A middle ground. You use contracted providers for certain care types but have more flexibility for others. Both insurers offer this, though the exact terms vary by specific product. Premiums sit between natura and restitutie.

Restitutie Policy

With a restitutie (reimbursement) policy, you can go to any registered Dutch healthcare provider — contracted or not — and your insurer reimburses you based on the NZa (Dutch Healthcare Authority) tariff. This gives you maximum freedom. It costs more: roughly EUR 10-12/month extra.

• Zilveren Kruis restitutie: ~EUR 153/month. Their “Zilveren Kruis Restitutie” product is popular among expats who travel frequently, work with internationally connected hospitals, or simply want no surprises about provider access.
• CZ restitutie: ~EUR 151/month. Available as “CZ Zorgbewust Restitutie.” Similar flexibility.

the editorial recommendation for expats: Unless you have a specific specialist or clinic you are attached to that is outside the contracted network, the natura policy is perfectly fine. The network for both insurers covers the vast majority of Dutch hospitals and GPs. Save the EUR 10/month and put it toward dental cover instead.

Aanvullende Verzekering: Supplementary Insurance

This is where real differences emerge. Supplementary insurance is entirely optional but genuinely useful for expats who want dental cover, more physiotherapy, glasses, or alternative treatments. Neither insurer is obliged to accept you for supplementary cover (they can reject you based on health history), so apply at the same time as your basic insurance rather than adding it later.

Dental Coverage

Adult dental care is not included in the basic package. Both insurers sell dental add-ons at different tiers.

Zilveren Kruis dental tiers (2026 approximate):

• Tandverzekering Basis (~EUR 10/month): covers check-ups and basic treatments up to ~EUR 250/year
• Tandverzekering Extra (~EUR 18/month): covers more treatments including fillings and extractions up to ~EUR 500/year
• Tandverzekering Compleet (~EUR 26/month): crowns, bridges, orthodontics up to ~EUR 1,500/year
• Tandverzekering Compleet Plus (~EUR 35/month): up to EUR 2,500/year, implants partially covered

CZ dental tiers (2026 approximate):

• Tand Basis (~EUR 8/month): check-ups and basic treatments up to EUR 200/year
• Tand Uitgebreid (~EUR 16/month): fillings, extractions up to EUR 400/year
• Tand Compleet (~EUR 22/month): crowns, bridges up to EUR 1,000/year
• Tand Compleet Plus (~EUR 30/month): up to EUR 2,000/year

CZ is marginally cheaper across the tiers, but Zilveren Kruis offers higher coverage ceilings at the top end. If you anticipate significant dental work — crowns, implants, orthodontics — the Zilveren Kruis Compleet Plus advantage can outweigh the higher monthly premium. For routine check-ups and the occasional filling, either will do.

I go into this in much more detail in the dental section below.

Physiotherapy

The basisverzekering covers physiotherapy only from session 21 onwards (for chronic conditions on the government list) or for a limited number of sessions for acute issues. For most people, the first 9-20 sessions of physio for a non-listed condition come out of your eigen risico and then your own pocket.

Both insurers offer physio add-ons:

• Zilveren Kruis: From ~EUR 5/month for 9 extra sessions, up to ~EUR 13/month for 27 additional sessions per year
• CZ: From ~EUR 6/month for 9 extra sessions, up to ~EUR 15/month for 27 additional sessions per year

Zilveren Kruis is marginally cheaper here, and their contracted physio network is large. If you run regularly, play sport, or have a physically demanding job, this add-on pays for itself quickly.

Alternative Medicine

Both offer add-ons covering acupuncture, homeopathy, osteopathy, and similar treatments. These are niche, but some expats — particularly those coming from countries where alternative medicine is mainstream — value them.

• Zilveren Kruis: Included in some higher-tier aanvullende packages
• CZ: Available as a separate add-on at ~EUR 4-6/month

Glasses and Contact Lenses

Neither basic policy covers glasses for adults. Supplementary options exist at both insurers, typically reimbursing EUR 100-200 every two years depending on the tier. Honestly, these add-ons are rarely worth the premium cost unless you buy expensive frames — a basic pair from a Dutch optician costs EUR 100-150 all in.

Network and Contracted Care

This is practical and often overlooked by expats who assume all Dutch insurers give access to the same hospitals. They do not.

CZ has strong contracts in the south: St. Antonius Ziekenhuis, Catharina Ziekenhuis, Elisabeth-TweeSteden Ziekenhuis, Maastricht UMC+. In the Randstad, their network is solid but occasionally a specific clinic or specialist practice will not be contracted. Before you sign up, always check CZ’s online zorgzoeker (care finder) to verify that your preferred GP practice and any specialists you already use are in network.

Practical advice: If you already have a GP (huisarts), check their contract status with both insurers before choosing. Switching GPs after moving is common anyway, but if you are settled with a particular practice, this matters.

English Language Support and Expat Friendliness

Neither Zilveren Kruis nor CZ is a purpose-built expat insurer. They are Dutch companies serving a Dutch market that happens to include a large international population. That said, they differ meaningfully in how accessible they are to non-Dutch speakers.

Zilveren Kruis:

• Customer service: English-speaking agents available, though you may have to ask specifically or wait longer
• Website: Key sections available in English, including policy summaries and claim forms
• App (Mijn Zilveren Kruis): Dutch only, but functional and intuitive enough that basic navigation is not difficult
• Letter correspondence: In Dutch. Use DeepL — it handles Dutch medical/insurance terminology reasonably well

CZ:

• Customer service: Limited English. Most agents speak Dutch only, though younger staff often manage basic English
• Website: Primarily Dutch
• App (Mijn CZ): Dutch only
• Letter correspondence: Dutch

If English support is a dealbreaker for you, neither is ideal. For a genuinely English-first experience, look at Cigna or Allianz Care as international health insurers (though they are significantly more expensive). The expat insurance guide covers those options.

Claims Process and Apps

Zilveren Kruis App (Mijn Zilveren Kruis)

The app is functional and covers the basics well:

• View your policy and coverage details
• Submit and track claims (declaraties)
• Check your eigen risico progress
• Request referral authorisations
• Find contracted providers

CZ App (Mijn CZ)

Larger claims (hospital stays, specialist courses of treatment) take 2-4 weeks to process at both insurers, which is normal. The insurer pays the hospital directly in most cases when you use a contracted provider — you will only need to submit a claim yourself for non-contracted care or reimbursable expenses like physiotherapy and dental.

Dental Coverage Deep Dive

Without supplementary dental cover, you pay all of this yourself (minus eigen risico contributions where applicable). Here is how to think about which insurer’s dental add-on makes sense for you:

For Light Users (annual check-up, occasional filling)

Recommended: CZ Tand Basis (~EUR 8/month = EUR 96/year)

If your dental health is good and you only go once a year for a check-up plus maybe one filling every few years, the CZ Tand Basis is sufficient. You will get your check-up covered, and the add-on pays for itself if you have any treatment at all. The EUR 200/year ceiling is adequate for light users.

For Moderate Users (regular check-ups, multiple fillings, potential crowns in coming years)

Recommended: Zilveren Kruis Tandverzekering Extra (~EUR 18/month = EUR 216/year)

The EUR 500/year ceiling and broader treatment coverage makes this worthwhile if you need anything beyond basic check-ups. With one crown every few years, this add-on easily covers its cost.

For Heavy Users (orthodontics, implants, multiple major restorations)

Recommended: Zilveren Kruis Tandverzekering Compleet Plus (~EUR 35/month = EUR 420/year)

The EUR 2,500/year ceiling and partial implant coverage is the best available from either insurer for major dental work. If you know you have significant work coming — say, your Dutch dentist has flagged multiple teeth that need crowns — getting this add-on in January before the work starts can save you thousands.

One important rule: Both insurers apply a waiting period of typically 3-6 months before certain dental treatments are reimbursed. Do not sign up for dental add-on cover the week before you need an expensive procedure and expect it to be covered. Check the policy terms carefully.

Mental Health Coverage

Mental health care (GGZ — Geestelijke Gezondheidszorg) is included in the basisverzekering for both insurers, but with some nuance that expats often miss.

What is covered in the basic package:

• Specialised mental health care (gespecialiseerde GGZ): depression, anxiety disorders, PTSD, eating disorders, personality disorders — when referred by your GP and provided by a contracted GGZ provider
• The eigen risico applies to mental health care (EUR 385)
• GP consultations about mental health are eigen risico exempt

What is not covered:

• General counselling or life coaching
• Relationship therapy
• Expat-specific adjustment issues that do not meet clinical diagnosis thresholds
• Self-help apps and programmes

Practical reality for expats: Mental health difficulties related to relocation, loneliness, culture shock, and language isolation are extremely common and very real. But getting a referral through the Dutch system for these issues can be slow — waiting lists for contracted GGZ providers in Amsterdam can be 6-12 months. Neither Zilveren Kruis nor CZ has a structural advantage here; the problem is systemic, not insurer-specific.

Both insurers cover a small number of sessions with a POH-GGZ (a mental health nurse attached to your GP practice) within the basic package, without hitting your eigen risico. This is often the fastest first step.

If you want access to private English-speaking therapists without long waits, you will typically pay out of pocket — EUR 80-120 per session — as private practice therapists are often not contracted. Some expats budget for this separately.

Pros and Cons Summary

Zilveren Kruis

Pros:

• Largest insurer in the Netherlands — strong negotiating position and broad network
• Best English-language support among Dutch domestic insurers
• Higher dental reimbursement ceilings at premium tiers
• Slightly better physiotherapy add-on pricing
• Widely recognised — rarely encounter a provider who does not accept them

Cons:

• Marginally higher premiums across most policy types
• Customer service wait times can be long during peak periods (January, after open enrolment)
• Website can be complex to work through when looking for specific policy details
• Letters and communications remain Dutch-only

CZ

Pros:

• Slightly lower natura premiums — EUR 2-5/month difference adds up
• Excellent coverage in south Netherlands (Noord-Brabant, Zeeland, Limburg)
• Clean, intuitive app with real-time eigen risico tracking
• Slightly lower dental add-on premiums at entry/mid tiers
• Reliable claims processing

Cons:

• Less expat-oriented overall

A Third Option Worth Knowing: a.s.r.

Zilveren Kruis and CZ are not the only two structures on offer. a.s.r. splits its basisverzekering three ways instead of the natura/combinatie/restitutie pattern used above — Bewuste Keuze (non-contracted care reimbursed at a maximum of 65%), Ruime Keuze (up to 85%, and 75% for GGZ and district nursing) and Eigen Keuze (100% at contracted and non-contracted providers) — with 100% free hospital choice at any Dutch hospital on all three (asr.nl/zorgverzekering/basisverzekering, checked 17 September 2026). On dental the comparison above does not transfer: a.s.r. keeps dental out of its supplementary packages altogether and sells a separate tandartsverzekering in five levels with annual ceilings of EUR 250, EUR 250, EUR 250, EUR 500 and EUR 750, from EUR 10 a month and reimbursed from age 18 (asr.nl/zorgverzekering/tandartsverzekering, checked 17 September 2026) — so heavy dental users should hold those ceilings against the Zilveren Kruis top tier before switching. The switching mechanics are the same as for either insurer above: cover starts on 1 January, and if you switch before 31 December your new insurer cancels the old policy for you (asr.nl/zorgverzekering/overstappen, checked 17 September 2026). a.s.r.’s health insurance pages are Dutch-language; the English entry URLs we tried returned a 404 on 17 September 2026.

How to Sign Up

The most practical way to compare and sign up for either Zilveren Kruis or CZ is through Independer. Independer is the Netherlands’ largest insurance comparison platform, and they are accustomed to expat users. You can filter by insurer, policy type, and supplementary packages, and the sign-up process is handled in one place.

Why use a comparison platform rather than going direct?

1. You see side-by-side pricing for the current year — insurer websites can be confusing about which package includes what
2. Independer has Dutch expat-friendly FAQ content
3. If you are eligible for zorgtoeslag (healthcare allowance), Independer shows your estimated net cost after the subsidy
4. You can sign up for basic and supplementary insurance together in one transaction

Am I eligible for zorgtoeslag?

Zorgtoeslag is a government subsidy for people on lower to mid incomes. In 2026, if your annual income is below approximately EUR 38,000 (single) or EUR 48,000 (partners), you are likely eligible for a monthly contribution of EUR 50-130 toward your premium. You apply through the Belastingdienst (Dutch tax authority), not through your insurer. If you are on the 30% ruling, your taxable income figure used for zorgtoeslag calculations changes — check my 30% ruling guide for detail on how that interacts.

Timeline for new expats:

You must arrange health insurance within 4 months of registering in the Netherlands (i.e., within 4 months of getting your BSN and registering with a gemeente). Coverage is backdated to your registration date if you sign up within this window. Do not leave it until the last day — backdated premiums for several months will be invoiced at once, which can be a shock.

If you want a tool to match your situation to the best policy, try the Insurance Chooser tool — it asks a few questions and gives you a filtered recommendation.

My Overall Take

The honest answer is that both are solid choices. The Dutch healthcare system, whatever its quirks and waiting lists, delivers good outcomes — and either of these two large, established insurers will cover you properly for the things that matter most.

Where most expats go wrong is not on the choice between Zilveren Kruis and CZ — it is on skipping supplementary dental cover and then being hit with a EUR 800 crown bill they had not budgeted for. Sort that before worrying too much about the base premium difference.

One situation where neither Zilveren Kruis nor CZ is the right answer: the gap before your Dutch registration is complete, or a short visit before you become a legal resident. Both require you to be registered to sign up. For that interim window — or if you are travelling outside the Netherlands for an extended period — SafetyWing Nomad Insurance offers temporary emergency medical coverage from around $45/month. It is not a substitute for Dutch basisverzekering (and cannot legally replace it once you are a resident), but as a stop-gap or travel layer it does the job at a fraction of the cost of a full international plan.
