Public Health Insurance (GKV)

What is GKV?

Germany’s public health insurance system — the Gesetzliche Krankenversicherung (GKV) — is one of the oldest social insurance systems on the planet. It traces its roots all the way back to 1883, when Chancellor Otto von Bismarck pushed the Krankenversicherungsgesetz (Health Insurance Act) through the Reichstag. Bismarck’s motivations were equal parts pragmatism and politics: he wanted to take the wind out of the growing socialist movement by giving workers a genuine safety net. The result was the world’s first statutory health insurance system — and it still forms the backbone of German healthcare today.

At its core, the GKV operates on the Solidaritätsprinzip (solidarity principle). Everyone pays in according to their income, and everyone receives the same standard of care regardless of how much they contribute. A CEO earning the maximum assessable income and a trainee earning minimum wage walk into the same doctor’s office and receive the same treatment. There are no “tiers” of coverage, no pre-existing condition exclusions, no waiting periods for benefits, and no lifetime caps. If you’re in, you’re in — fully.

Another key principle is Sachleistungsprinzip (benefits in kind). Unlike private insurance where you pay the doctor, get a bill, and then submit it for reimbursement, public insurance works seamlessly: you show your electronic health card (elektronische Gesundheitskarte) at the doctor’s office, receive treatment, and leave. The doctor bills your Krankenkasse directly through the regional Association of Statutory Health Insurance Physicians (Kassenärztliche Vereinigung). You never see a bill for covered services. It’s frictionless.

Today, approximately 74 million people — around 90% of Germany’s population — are insured through roughly 95 statutory health insurance funds (down from over 1,000 in the 1990s due to mergers). The system is governed primarily by Book V of the Social Code (Sozialgesetzbuch V — SGB V).

Who Must Join GKV?

Germany has a concept called Versicherungspflicht (mandatory insurance obligation). If you fall into certain categories, you don’t get to choose — you must be in GKV. Here’s who that covers:

Employed Persons (Pflichtversicherte)

If you’re an employee (Arbeitnehmer) earning a gross annual salary below the Versicherungspflichtgrenze (mandatory insurance threshold), you are automatically enrolled in GKV. In 2026, this threshold sits at €77,400 per year (€6,150/month). If your income is below this, you’re what’s called a Pflichtversicherter (mandatorily insured person) and you simply cannot opt into private insurance — end of story.

If your income exceeds €77,400, you become versicherungsfrei (exempt from mandatory insurance) and may choose to either stay in GKV voluntarily (freiwillig versichert) or switch to private health insurance (PKV). Most people who cross this threshold for the first time stick with GKV — especially if they have families.

Mini-Job Workers

If you earn up to €538/month in a mini-job (geringfügige Beschäftigung), your employer pays a flat 13% health insurance contribution, but you’re not automatically insured through GKV. You need to have coverage from elsewhere — typically through family insurance, your main job, or as a student.

Apprentices (Auszubildende)

All apprentices are mandatorily insured in GKV from day one, regardless of their training salary. No exceptions.

Pensioners (KVdR)

Retirees who spent the majority of the second half of their working life in GKV qualify for the Krankenversicherung der Rentner (KVdR). This is a significant benefit: contributions are calculated only on your pension income and certain other earnings, and the pension insurance carrier (Deutsche Rentenversicherung) pays the “employer’s share.” If you don’t qualify for KVdR, you’re insured as a voluntary member, which can mean paying contributions on all income sources — ouch.

Unemployed Persons

Recipients of Arbeitslosengeld I (ALG I) remain insured in GKV, with the Federal Employment Agency (Bundesagentur für Arbeit) paying the contributions. If you receive Bürgergeld (formerly ALG II / Hartz IV), the Jobcenter pays your health insurance contributions directly.

Artists and Journalists (KSK)

Self-employed artists, writers, musicians, and journalists can access GKV through the Künstlersozialkasse (KSK) — a brilliant institution unique to Germany. The KSK acts as a quasi-employer: you pay roughly half the contribution, the KSK covers the other half (funded partly by levies on companies that use creative services, partly by a federal subsidy). This makes GKV affordable for freelance creatives who would otherwise face the full self-employed contribution burden.

Students

Students enrolled at a German university are mandatorily insured in GKV at a heavily subsidized rate (around €120/month including nursing care insurance) until age 30 or the 14th semester, whichever comes first. After that, you can remain voluntarily insured at a higher rate.

How Contributions Work

GKV contributions are income-based — the more you earn, the more you pay, up to a ceiling. Here’s how it breaks down:

The Base Rate

The Allgemeiner Beitragssatz (general contribution rate) is set by law at 14.6% of your gross income. This is split equally between you and your employer: 7.3% each. This rate has been stable for years and is the same across all Krankenkassen.

The Zusatzbeitrag (Supplementary Contribution)

On top of the base rate, each Krankenkasse charges a Zusatzbeitrag (supplementary contribution). This is where the kassen actually compete — see our costs breakdown for detailed calculations. In 2026, the average Zusatzbeitrag is around 1.7%, but individual kassen range from about 0.9% to over 2.5%. Since January 2019, the Zusatzbeitrag is also split 50/50 between employer and employee. So if your kasse charges 1.7%, you and your employer each pay 0.85%.

The Income Ceiling (Beitragsbemessungsgrenze)

You don’t pay contributions on your entire income — only up to the Beitragsbemessungsgrenze (BBG), the contribution assessment ceiling. In 2026, this is €62,100 per year (€5,175/month). Any income above this ceiling is contribution-free. This means there’s a maximum monthly contribution regardless of how much you earn.

Let’s calculate the maximum: €5,175 × 16.3% = approximately €843.53/month total, of which your employee share is about €421.76/month. That’s the most any employed person pays for GKV health insurance (using the average Zusatzbeitrag). Your actual amount depends on your kasse’s specific Zusatzbeitrag.

Reduced Rate (Without Sick Pay)

If you’re voluntarily insured and waive your entitlement to sick pay (Krankengeld), you pay a reduced base rate of 14.0% instead of 14.6%. This applies mainly to self-employed people who arrange their own sick pay coverage. The 0.6% savings can add up, but you’re giving up a significant benefit — think carefully.

Contributions on Other Income

For voluntarily insured members and pensioners not in KVdR, contributions aren’t just calculated on employment income. The Krankenkasse will also assess contributions on:

• Rental income (Mieteinnahmen)
• Capital gains (Kapitalerträge) above the €1,000 saver’s allowance (Sparerpauschbetrag)
• Private pensions and annuities
• Other taxable income

Nursing Care Insurance (Pflegeversicherung)

Whenever you hear about health insurance in Germany, nursing care insurance (Pflegeversicherung) is always right behind it. The two are legally bundled — you cannot have one without the other. Introduced in 1995 as Germany’s “fifth pillar” of social insurance, Pflegeversicherung covers the costs of long-term care if you become dependent due to age, illness, or disability.

Contribution Rates in 2026

The base rate for nursing care insurance is 3.4% of gross income, split between employer and employee. But here’s where it gets interesting:

• Childless surcharge (Kinderlosenzuschlag): If you are over 23 and have no children, you pay an additional 0.6%, bringing your total to 4.0%. This surcharge is paid entirely by the employee — your employer doesn’t share it.
• Reductions for parents: Parents with multiple children under 25 receive reductions. Starting from the second child, you get a 0.25% reduction per child, up to a maximum reduction of 1.0% (for 5+ children). So a parent of three children under 25 pays 3.4% minus 0.50% = 2.9%.

What’s Covered

GKV coverage is remarkably comprehensive. The Federal Joint Committee (Gemeinsamer Bundesausschuss, G-BA) determines which services are covered based on the principle that treatments must be “sufficient, appropriate, and economical” (ausreichend, zweckmäßig und wirtschaftlich). Here’s the full rundown:

Outpatient Doctor Visits

All visits to general practitioners (Hausärzte) and specialists (Fachärzte) are fully covered. You can see any GKV-contracted doctor without a referral (though some specialists prefer one). There are no visit limits and no deductibles for doctor visits.

Hospital Treatment (Krankenhausbehandlung)

Inpatient hospital stays are fully covered, including surgery, nursing care, medications during your stay, and meals. You’ll be in a shared room (typically 2-4 beds) with treatment by the duty doctor. Want a single room or treatment by the chief physician? That’s where supplemental private insurance (Zusatzversicherung) comes in.

Prescription Medications (Arzneimittel)

Most prescription drugs are covered, subject to co-payments (see below). Over-the-counter medications are generally not covered for adults, with exceptions for certain OTC drugs that are medically necessary. Children under 12 get all prescribed medications covered, including many OTC drugs.

Dental Care (Zahnbehandlung)

Basic dental care is covered: check-ups, fillings (amalgam as standard material), root canals, periodontal treatment, and extractions. Cosmetic dentistry and premium materials (ceramic fillings, implants) are generally not covered or only partially subsidized. For dentures and crowns, GKV pays a Festzuschuss (fixed subsidy) — typically 60% of the “standard care” cost, rising to 70% with 5 years of documented annual check-ups and 75% with 10 years (yourBonusheft).

Mental Health (Psychotherapie)

GKV covers psychotherapy quite generously. After an initial consultation (psychotherapeutische Sprechstunde, up to 6 sessions) and trial sessions (probatorische Sitzungen, 2-4 sessions), you can receive:

• Short-term therapy: up to 24 sessions
• Long-term therapy: up to 80 sessions for cognitive behavioral therapy, up to 100 for depth psychology, and up to 300 for psychoanalysis

The catch? Wait times. Finding a therapist with available GKV slots can take months. The Terminservicestelle (appointment service) of your regional KV can help, and is legally required to offer you an initial appointment within 4 weeks.

Maternity Benefits (Mutterschaftsleistungen)

GKV covers all prenatal and postnatal care: regular check-ups, ultrasounds (3 standard ones), blood tests, midwife services (Hebammenbetreuung), hospital delivery, and home births. You also receive Mutterschaftsgeld (maternity pay) of up to €13/day during the legal maternity protection period (6 weeks before and 8 weeks after birth), with your employer topping up to your full net salary.

Preventive Care (Vorsorgeuntersuchungen)

Germany’s GKV has an extensive preventive care program:

• General health check-up (Check-up): Once between ages 18-34, then every 3 years from age 35
• Skin cancer screening: Every 2 years from age 35
• Colon cancer screening: Stool test annually from 50, colonoscopy from 50 (men) or 55 (women)
• Mammography screening: Every 2 years, ages 50-69
• Cervical cancer screening: Annual PAP smear (20+), HPV test every 3 years (35+)
• Prostate screening: Annual from age 45
• Dental check-ups: Twice yearly
• Children’s U-examinations: U1-U9 (birth to age 5) plus J1-J2 for adolescents

Vaccinations (Impfungen)

All vaccinations recommended by the STIKO (Ständige Impfkommission — Standing Committee on Vaccination) are fully covered. This includes childhood vaccinations, flu shots, COVID boosters, shingles (Herpes zoster) for 60+, HPV for ages 9-17, and travel vaccinations for certain destinations (though coverage for travel vaccines varies by kasse).

Sick Pay (Krankengeld)

After your employer stops paying your full salary (at week 7 — see the dedicated section below), GKV pays you Krankengeld at 70% of your gross salary, capped at 90% of your net salary, for up to78 weeks per illness within a 3-year period.

Therapies and Rehabilitation

• Physiotherapy (Krankengymnastik): Covered with prescription, subject to co-payment
• Speech therapy (Logopädie): Covered with prescription
• Occupational therapy (Ergotherapie): Covered with prescription
• Medical rehabilitation (Reha): Covered, typically 3 weeks of inpatient rehab, every 4 years

Medical Aids (Hilfsmittel)

GKV covers medically necessary aids: wheelchairs, hearing aids (with a fixed subsidy), prosthetics, orthopedic shoes, blood glucose monitors for diabetics, and more. The Hilfsmittelverzeichnis lists everything that’s covered.

Ambulance and Emergency Services

Emergency ambulance transport and rescue helicopter services are covered. Non-emergency medical transport (to hospital, dialysis, radiation therapy) is also covered when medically necessary, subject to a €10 co-payment per trip.

Co-Payments (Zuzahlungen)

While GKV covers most everything, you do pay small co-payments (Zuzahlungen) for certain services. These are designed to prevent overuse, not to be a significant financial burden:

• Prescription medications: €5 to €10 per prescription, depending on the pack price (10% of the price, minimum €5, maximum €10). Many common generics are fully exempt from co-payments if the kasse has negotiated a rebate contract.
• Hospital stays: €10 per day, for a maximum of 28 days per calendar year = max €280/year.
• Rehabilitation: €10 per day.
• Medical aids: 10% of cost, minimum €5, max €10.
• Medical transport: €10 per trip.
• Physiotherapy/other therapies: 10% of cost plus €10 per prescription.

Annual Cap (Belastungsgrenze)

Here’s the crucial safety net: your total annual co-payments are capped at 2% of your gross household income. Once you hit that threshold, you’re exempt from all co-payments for the rest of the year. For chronically ill patients (Chroniker-Regelung), the cap drops to just 1%.

To qualify as chronically ill, you need to be in continuous treatment for the same condition for at least one year and meet one of several criteria (e.g., care level, disability of 60%+, or ongoing need for medical treatment).

How to Apply for Exemption (Zuzahlungsbefreiung)

Keep all your co-payment receipts throughout the year. Once your payments reach 2% (or 1%) of your household gross income, submit a Befreiungsantrag (exemption application) to your Krankenkasse with the receipts. They’ll issue an exemption card for the rest of the year. Some kassen let you pay the expected amount upfront at the start of the year and get immediate exemption.

Choosing a Krankenkasse

Since the Kassenwahlfreiheit (freedom to choose your health insurance fund) was introduced in 1996, you’re free to join any open Krankenkasse in Germany. And yes, you can switch. Here’s what actually differs between them, because the base coverage is identical by law:

Zusatzbeitrag Rates

This is the most tangible difference and directly affects your monthly paycheck. The spread between the cheapest and most expensive kasse can be over 1.5 percentage points. On a salary of €5,000/month, that’s roughly €37.50/month or €450/year in your pocket. Not nothing.

Bonus Programs (Bonusprogramme)

Many kassen offer cash bonuses or premium refunds for healthy behavior: gym memberships, completing preventive check-ups, participating in sports courses, maintaining a healthy BMI. Some programs can net you €100-300+ per year in bonuses.

Extra Services (Zusatzleistungen)

This is where kassen really differentiate themselves. Extras can include:

• Osteopathy: Many kassen cover 3-6 sessions per year (up to €40-60/session)
• Professional teeth cleaning (PZR): Subsidies of €40-100/year
• Travel vaccinations: Some kassen cover all travel vaccines, not just STIKO-recommended ones
• Extended screening: Additional cancer screenings, skin checks at younger ages
• Alternative medicine: Homeopathy, acupuncture, traditional Chinese medicine
• Online fitness/health courses: Free access to certified prevention courses
• Fertility treatment extras: Some kassen cover more than the mandatory 3 IVF cycles or cover a larger share of costs

Customer Service and Digital Offerings

App quality, English-language support, response times, online claims processing, electronic sick notes — these vary dramatically. If you don’t speak fluent German, a kasse with strong English support (like TK) makes a real difference.

How to Switch

You can switch your Krankenkasse at any time with a notice period. Since 2021, you can cancel your membership and the new kasse handles everything. If your current kasse raises its Zusatzbeitrag, you get a Sonderkündigungsrecht (special cancellation right) and can switch immediately. Your new membership begins at the start of the following month after the notice period.

The Big Players

With about 95 statutory health insurance funds in Germany, it can feel overwhelming. Here are the major players you’ll encounter:

Techniker Krankenkasse (TK)

Germany’s largest Krankenkasse with approximately11 million members. TK is consistently rated as the best overall kasse in independent tests. Their app (“TK-App”) is excellent, they offer strong English-language support (rare among kassen), and their extra services are comprehensive — including osteopathy, travel vaccines, professional teeth cleaning subsidies, and an extensive bonus program. Their Zusatzbeitrag is competitive. If you’re an expat or new to Germany, TK is the default recommendation for a reason.

AOK (Allgemeine Ortskrankenkasse)

The AOK is actually a federation of regional kassen (AOK Bayern, AOK Nordost, AOK Rheinland/Hamburg, etc.), with a combined membership of around 27 million — making the AOK system the largest overall. Each regional AOK has different Zusatzbeiträge and extra services. AOK’s strength is its extensive local presence with physical offices everywhere, which is helpful if you prefer in-person service. Coverage and extras vary significantly by region.

BARMER

Germany’s second-largest single kasse with about 9 million members. BARMER has good digital services, a comprehensive bonus program, and is particularly known for strong coverage of alternative medicine and telemedicine offerings. They have a nationwide network of offices.

DAK-Gesundheit

With approximately 5.5 million members, DAK is the third-largest nationwide kasse. They offer solid extra services and have been investing heavily in digital health offerings. DAK is known for good customer service and competitive bonus programs.

IKK (Innungskrankenkassen)

Originally the insurance funds for guild-based trades (craftspeople, artisans), the IKK kassen are now open to everyone. IKK classic is the largest, with competitive rates and solid extra services. They often have particularly good coverage for occupational health issues.

BKK (Betriebskrankenkassen)

Company-based health insurance funds — originally established by large employers. Many are now open to the public. Examples include BKK VBU, Audi BKK, BMW BKK, Bosch BKK, and many more. Some BKK kassen have very low Zusatzbeiträge, making them attractive for cost-conscious members. The trade-off can be fewer physical offices.

Knappschaft

Historically the miners’ insurance fund (Knappschaft-Bahn-See), now open to everyone. Known for very comprehensive extra services, including their own network of hospitals and clinics. A hidden gem that many people overlook.

HEK (Hanseatische Krankenkasse)

A smaller kasse with around 530,000 members, but consistently ranked among the best for customer service and extra services. HEK often has a competitive Zusatzbeitrag and generous coverage for osteopathy, natural remedies, and professional teeth cleaning.

Family Insurance (Familienversicherung)

One of the biggest advantages of GKV over private insurance: Familienversicherung. Your spouse and children can be insured through your GKV membership at absolutely no additional cost. Zero. Nada. This is a massive deal for families and one of the main reasons high earners with dependents often choose to stay in GKV rather than switching to private.

Who Can Be Co-Insured?

• Spouse or registered life partner — if they have no income or very low income
• Children — biological, adopted, stepchildren, grandchildren if they live in your household

Income Limits for Family Insurance

To qualify, the co-insured family member’s total income must not regularly exceed:

• €505/month from all income sources (general limit), or
• €538/month if the income comes exclusively from a mini-job

If your spouse starts a job earning €600/month, they’d need their own insurance — either through their employer if it’s a regular job, or as a voluntary GKV member.

Age Limits for Children

• Generally covered until age 18
• Until age 23 if not employed
• Until age 25 if in education (school, university, vocational training, or voluntary social/ecological year)
• Children with disabilities: no age limit if the disability occurred before the age limit

When Family Insurance Doesn’t Work

There are situations where Familienversicherung is not available:

• The higher-earning spouse is privately insured (PKV) and earns above the Versicherungspflichtgrenze — in this case, the children cannot be family-insured through the GKV-insured parent
• The family member is self-employed with income above the limits
• The family member is a civil servant (Beamter)
• The family member already has mandatory insurance through their own employment

Sick Pay (Krankengeld)

Germany’s sick pay system is one of the most generous in the world, and it works in two phases:

Phase 1: Employer Pays (Entgeltfortzahlung)

For the first 6 weeks (42 calendar days) of illness, your employer continues to pay your full salary. This is called Entgeltfortzahlung im Krankheitsfall and is guaranteed by law (Entgeltfortzahlungsgesetz). You get 100% of your regular salary — no reduction. This clock resets for each new, unrelated illness.

Phase 2: Krankengeld from Your Kasse

Starting from week 7 (day 43), your Krankenkasse takes over and pays Krankengeld. The calculation:

• 70% of your gross salary (Regelentgelt), but
• capped at 90% of your net salary — whichever is lower
• Additionally capped at the Beitragsbemessungsgrenze (€5,175/month in 2026), so the maximum Krankengeld is about €3,622.50/month gross before deductions for social insurance contributions
• You still pay employee contributions to pension, unemployment, and nursing care insurance from your Krankengeld (but not health insurance contributions)

Duration

Krankengeld is paid for a maximum of 78 weeks (546 calendar days, minus the 6 weeks of employer pay = 72 weeks of actual Krankengeld) for the same illness within a 3-year period. If you recover, work for at least 6 months, and then fall ill again with the same condition, the 78-week clock restarts.

How to Apply

You don’t need to “apply” in the traditional sense. Your doctor issues a Arbeitsunfähigkeitsbescheinigung (AU — certificate of incapacity), which is transmitted electronically to your employer and Krankenkasse. From week 7, your kasse automatically initiates Krankengeld payments. However, it’s critical that there are no gaps in your AU certificates — even a single day gap can end your Krankengeld entitlement.

Aussteuerung — What Happens After 78 Weeks?

When your Krankengeld entitlement runs out (Aussteuerung), several things happen:

• Your employer may terminate your employment (after following the required process)
• You can apply for disability pension (Erwerbsminderungsrente) if you’re unable to work
• You can register as unemployed and receive ALG I
• Your health insurance continues — you don’t lose coverage

Voluntary GKV Membership

Not everyone in GKV is there because they have to be. Several groups can or must join GKV as voluntary members (freiwillig Versicherte):

• High-earning employees above the Versicherungspflichtgrenze (€77,400/year) who choose to stay in GKV
• Self-employed persons (Selbständige) who don’t qualify for or choose not to join PKV
• Freelancers (Freiberufler) — same as above
• Persons returning from abroad who were previously in GKV
• Former civil servants or former PKV members who re-enter GKV eligibility

How Contributions Are Calculated

This is where voluntary membership gets expensive. As a voluntary member, contributions are assessed on your total income — not just employment income. This includes:

• Employment income
• Self-employment profits
• Rental income
• Capital gains (above €1,000 allowance)
• Private pensions
• Other taxable income

If you’re self-employed with no employer, you pay the full contribution yourself — both the employee and employer share. That means 14.6% + Zusatzbeitrag (let’s say 1.7%) = 16.3% of your income, plus nursing care insurance.

Minimum and Maximum Contributions

There’s a minimum income floor (Mindestbemessungsgrundlage) for contribution assessment. In 2026, this is approximately €1,178.33/month. Even if you earn less than this (or nothing), you’ll pay contributions as if you earned €1,178.33. At the full rate of 16.3%, that’s a minimum of roughly €192/month for health insurance alone, plus nursing care.

At the other end, the maximum contribution is capped at the Beitragsbemessungsgrenze (€5,175/month). As a self-employed voluntary member paying the full rate, the maximum health insurance contribution is approximately €843.53/month (at the average Zusatzbeitrag) — and with nursing care insurance added, you’re looking at over €1,050/month total.

Proving Your Income

As a voluntary member, your Krankenkasse will ask for your most recent tax assessment (Steuerbescheid) or an income declaration. For the self-employed, contributions are initially set based on estimated income and then adjusted retroactively once the actual tax assessment arrives — which can mean a nasty surprise (or a pleasant refund). Keep reserves for potential back-payments.
