How chronic illnesses impact German health insurance

If you have a chronic illness and are moving to Germany — or already here — one of the first questions you'll face is: how does this affect my health insurance?

The good news: Germany's healthcare system provides strong protections for people with chronic conditions. But how it works depends on whether you're in public (GKV) or private (PKV) insurance.

In this guide, you'll learn:

• How chronic illness is defined in Germany
• How GKV and PKV each handle chronic conditions
• How co-payment exemptions work (and how to apply)
• What Disease Management Programs (DMPs) offer
• Practical advice for expats managing chronic illness in Germany

What counts as a chronic illness in Germany?

The Robert Koch Institute (RKI) — Germany's federal institute for disease control — states there is no single formal definition. However, any condition that is not curable and has a lasting negative impact on health is generally considered chronic.

Common examples include:

• Diabetes (Type 1 and Type 2)
• Heart disease and hypertension
• Chronic lung disease (asthma, COPD)
• Cancer (during and after treatment)
• Mental health conditions (depression, anxiety disorders)
• Autoimmune diseases (MS, rheumatoid arthritis, Crohn's)
• Chronic kidney disease

According to RKI data, chronic illnesses account for roughly three-fourths of all deaths in Germany and about one-fourth of total healthcare spending.

This is distinct from pre-existing conditions — which refers to any condition you already have when applying for insurance (whether chronic or not).

Public health insurance (GKV) and chronic illness

Public health insurance is the strongest option for anyone with a chronic condition. Here's why:

No exclusions, no rejections

GKV must accept you regardless of health status. There are no health questionnaires, no risk surcharges, and no exclusions. Your chronic illness is fully covered from day one — including ongoing treatment, medication, specialist visits, and hospital stays.

Reduced co-payment cap (Belastungsgrenze)

In Germany's public insurance system, everyone pays small co-payments (Zuzahlungen) for prescriptions, hospital stays, and certain treatments. But there's a cap:

Example: If your household earns €40,000/year gross:

• Standard cap: €800/year in co-payments
• Chronic illness cap: €400/year

Once you hit the cap, you receive a Befreiungsausweis (exemption card) from your insurer — no more co-payments for the rest of the calendar year.

How to qualify for the 1% cap

To qualify as severely chronically ill (schwerwiegend chronisch krank), you must meet these criteria:

1. The illness has existed for at least one year
2. You require quarterly treatment from a doctor
3. At least one of the following applies:
   • You need continuous treatment to prevent the illness from becoming life-threatening
   • Your life expectancy would be reduced without treatment
   • Your quality of life would be permanently impaired

How to apply:

1. Visit your Hausarzt and request Form 55 (Bescheinigung schwerwiegend chronische Erkrankung)
2. Your doctor completes the form confirming your condition
3. Submit it to your GKV provider
4. Your insurer recalculates your co-payment cap to 1%

The Befreiungsausweis is valid for one calendar year and must be renewed annually.

Alternative qualification: You also qualify if you have Care Level 3 or higher (Pflegegrad 3+) or a disability rating of 60% or more.

Disease Management Programs (DMPs)

One of the biggest benefits for chronically ill GKV members is access to Disease Management Programs (Chronikerprogramme). These are structured treatment programs with regular check-ups, coordinated specialist care, and patient education.

DMPs are available for:

Enrollment is voluntary. Ask your Hausarzt to enroll you — participation is free and often improves outcomes because it ensures consistent, coordinated care.

Private health insurance (PKV) and chronic illness

Private health insurance handles chronic illness very differently from GKV:

Application: Health questionnaire required

When applying for PKV, you must disclose your full medical history in the Gesundheitsfragen (health questionnaire). Chronic conditions typically result in one of three outcomes:

Different insurers assess risk differently — a rejection from one doesn't mean a rejection from all.

If you're already in PKV when diagnosed

If you develop a chronic illness after joining PKV, your insurer cannot cancel your policy or exclude the new condition. Your tariff conditions remain unchanged. This is a key advantage of PKV: once accepted, your coverage is guaranteed for life.

The Basistarif safety net

If you can't get standard PKV coverage due to chronic illness, every insurer must offer you the Basistarif — a basic tariff with GKV-equivalent coverage. No health check required, no exclusions. The maximum premium is capped at €1,017.18/month in 2026.

Our recommendation for expats with chronic illness

For most people with chronic conditions, GKV is the better choice:

• No rejection risk
• No surcharges
• Full coverage from day one
• Access to DMPs
• Lower co-payment cap (1% vs 2%)

Expat health insurance generally does not cover pre-existing or chronic conditions — it's designed for short-term, healthy newcomers. If you have a chronic illness, prioritize getting into GKV or, if eligible, PKV with appropriate coverage.

Medication and chronic illness

If you're managing a chronic condition, you'll need regular prescriptions. Here's how the system works:

• Prescription medications: Covered by GKV with a co-payment of 10% per item (minimum €5, maximum €10)
• Generic substitution: Pharmacies may substitute your prescribed medication with a generic equivalent. If you need a specific brand, your doctor can note "aut idem" on the prescription to prevent substitution.
• Festbetrag (reference price): GKV sets a maximum reimbursement for medication groups. If your medication exceeds this, you pay the difference.
• Co-payment exemption: Once you hit the 1% cap (see above), prescription co-payments are waived for the rest of the year.

Rehabilitation (Reha) for chronic illness

Germany's healthcare system includes a strong rehabilitation component. If your chronic illness affects your ability to work or function:

• Medical Reha: Covered by health insurance or pension insurance (DRV). Typically 3 weeks in a specialized clinic.
• Occupational Reha: Focused on returning to work. Covered by DRV if you've paid into the pension system.
• Your doctor or insurer can initiate a Reha application. You generally have a right to rehabilitation every 4 years.
