German health insurance explained: GKV, PKV and Zusatzversicherung

The German health insurance system: an overview

Germany has one of the most comprehensive healthcare systems in the world, but for newcomers it can feel overwhelming at first. There are two entirely separate systems running side by side, a set of strict eligibility rules that determine which one applies to you, and a third layer of optional coverage on top. Understanding how all three pieces fit together will help you make confident decisions from day one.

This guide explains the statutory system (GKV), the private system (PKV), and supplemental insurance (Zusatzversicherung) in plain language. It also covers the key numbers and thresholds that apply in 2026.

GKV — the statutory health insurance system

What GKV is and how it works

GKV stands for Gesetzliche Krankenversicherung, or statutory health insurance. It is the default system that covers roughly 90 percent of people living in Germany. Coverage is provided through non-profit funds called Krankenkassen, such as TK, AOK, BARMER, and DAK. While each fund sets its own supplementary contribution rate, the benefits they must provide are defined by law — meaning the core coverage is largely identical across all funds.

GKV is financed through income-based contributions. In 2026, the general contribution rate is 14.6 percent of your gross salary, split equally between employer and employee. Each fund also levies an additional average rate (Zusatzbeitrag) of around 2.5 percent, though this varies by fund. The total is capped at the contribution assessment ceiling (Beitragsbemessungsgrenze), which stands at €5,512.50 per month in 2026. Any income above that ceiling is not subject to GKV contributions.

Who must join GKV

If you are an employee earning below the annual insurance threshold (Versicherungspflichtgrenze) of €73,800 per year in 2026, you are legally required to be insured through GKV. This applies to most employees, students enrolled at German universities, recipients of unemployment benefits, and pensioners. Freelancers, civil servants, and higher-earning employees have more flexibility.

What GKV covers

Statutory insurance covers a broad range of services, including:

• Visits to general practitioners and specialists
• Hospital treatment including surgery
• Prescription medication (with small co-payments)
• Mental health therapy (subject to waiting lists)
• Maternity care and childbirth
• Preventive screenings and vaccinations
• Dental check-ups and basic dental treatment
• Sick pay (Krankengeld) after six weeks of employer-paid sick leave

One significant advantage of GKV is family coverage. Spouses and children who have no income of their own can be co-insured at no extra cost. This is a meaningful financial benefit for families where one partner does not work.

PKV — the private health insurance system

What PKV is and how it works

PKV stands for Private Krankenversicherung, or private health insurance. Unlike GKV, PKV is provided by for-profit insurers, and premiums are calculated based on your age, health status, and the level of coverage you choose — not your income. This means a young, healthy person can pay relatively low premiums, while older applicants or those with pre-existing conditions may face significantly higher costs.

PKV policies are individual contracts. Every insured person pays their own premium, which means PKV has no family co-insurance benefit. Insuring a non-working spouse and children separately can make PKV considerably more expensive than GKV for families.

Who can join PKV

Access to PKV is restricted. You are eligible to switch to private insurance if you are:

• An employee whose gross salary exceeds the Versicherungspflichtgrenze of €73,800 per year in 2026
• A self-employed person or freelancer (Selbstständiger)
• A civil servant (Beamter), who typically receives a state subsidy called Beihilfe that makes PKV particularly attractive

Importantly, once you leave GKV for PKV, returning to statutory insurance later in life can be very difficult. This is a long-term financial decision that deserves careful consideration.

What PKV typically offers

Private insurance contracts often include benefits not available under GKV, such as:

• Treatment by senior physicians (Chefarztbehandlung)
• Private hospital rooms
• Faster appointments with specialists
• More comprehensive dental coverage
• Broader coverage for alternative therapies
• Reimbursement-based billing rather than direct billing

The reimbursement model means you pay the doctor first and then claim back from your insurer. Many PKV holders set a voluntary deductible (Selbstbehalt) to lower premiums, then submit only larger bills for reimbursement.

Zusatzversicherung — supplemental insurance to fill the gaps

Supplemental health insurance, known in German as Zusatzversicherung, is optional top-up coverage that works alongside your existing GKV or PKV policy. It does not replace statutory or private insurance — instead, it plugs specific gaps that your main policy does not cover fully.

Common types of supplemental coverage

The most popular supplemental policies in Germany include:

• Dental supplemental insurance (Zahnzusatzversicherung): GKV covers only basic dental care. For crowns, implants, or high-quality fillings, GKV pays a fixed subsidy and you pay the rest. Dental supplemental insurance covers a significant share of those out-of-pocket costs.
• Hospital supplemental insurance (Krankenhaustagegeld / stationäre Zusatzversicherung): This provides access to a private or semi-private hospital room, chief physician treatment, and sometimes a daily cash benefit during your hospital stay.
• Vision supplemental insurance (Sehhilfen-Zusatzversicherung): GKV no longer covers glasses or contact lenses for adults. Supplemental cover reimburses part of the cost of corrective eyewear.
• Alternative medicine (Heilpraktikerversicherung): Covers treatments from naturopaths and alternative practitioners that GKV excludes.
• Outpatient supplemental insurance (ambulante Zusatzversicherung): Provides broader reimbursement for outpatient services, professional cleaning, or additional preventive care.

Who benefits most from Zusatzversicherung

Supplemental insurance is particularly worthwhile for GKV members who want specific benefits — high-quality dental care, private hospital accommodation, or vision coverage — without committing to the full cost and complexity of switching to PKV. It is also increasingly popular among expats who are accustomed to more comprehensive dental or specialist access in their home countries.

Premiums vary widely depending on your age, health history, and the level of coverage. Applying while you are young and healthy generally results in lower and more stable premiums.

Choosing the right setup as an expat

Most expats arriving in Germany as employees will automatically be enrolled in GKV. Your employer handles the registration and contributions are deducted from your payslip. You choose your fund, and coverage begins almost immediately.

If you are self-employed or a higher earner, you will need to actively decide between GKV and PKV. Key questions to weigh include your age, your health, whether you have a family, how long you plan to stay in Germany, and your expected future income trajectory.

For many people in GKV, adding one or two targeted Zusatzversicherung policies — particularly dental and hospital cover — offers a practical way to upgrade day-to-day healthcare quality without a full system change.

Important things to know before you decide

• Switching from GKV to PKV is generally only possible once per year after meeting the income threshold for at least 12 consecutive months.
• Pre-existing conditions can lead to premium surcharges or exclusions in PKV — disclose everything honestly during the application process.
• Civil servants should investigate Beihilfe entitlements carefully, as these subsidies can significantly affect the cost comparison between GKV and PKV.
• EU citizens and those covered by bilateral social security agreements may have specific rights regarding GKV enrollment.
