2020 Supplemental Health Insurance Market: A Deep Dive into Growth, Winners, and Losers
Understanding market trends is crucial when you're evaluating your health insurance options. In 2020, a clear divergence emerged in the German private health insurance (PKV) landscape. While the market for full private coverage (Vollversicherung) remained stagnant, the segment for supplemental health insurance (Krankenzusatzversicherung) experienced significant growth. This trend mirrors patterns in the United States, where core Medicare or employer plans are often supplemented with Medigap, dental, or vision policies. This analysis breaks down the key players, winners, and losers, providing you with the insights needed to navigate your supplemental coverage choices effectively.
Market Overview: Stagnation in Full Coverage vs. Growth in Supplements
If you're considering private health insurance, it's important to know the broader context. In 2020, the total number of full private health insurance contracts in Germany slightly declined by 0.1%, with nineteen insurers reporting a loss. This stagnation has been a multi-year trend.
In stark contrast, the supplemental insurance market is thriving. According to a study by Assekurata, this segment grew by 744,562 contracts—a robust increase of 2.8% from 2019 to 2020. By the end of 2020, a total of 27.4 million people in Germany held a supplemental health insurance policy. This growth indicates a strong consumer focus on enhancing core coverage, whether it's Germany's public health insurance (GKV) or a basic private plan, with add-ons for dental, hospital comfort, or alternative medicine.
The Losers: Insurers Who Lost Ground in Supplemental Coverage
Despite overall market growth, a handful of insurers saw their supplemental customer base shrink. Only six companies experienced a net loss in this segment. Here are the key players who lost the most customers in absolute terms:
- Signal Iduna: The biggest loser, with a net loss of 9,854 persons. However, given its large existing customer base (it's the third-largest market leader), this represents a relatively small decline of 0.52%.
- Continentale: Lost 7,286 persons.
- AXA: Lost 5,989 persons.
Other companies with smaller losses included Süddeutsche, LKH, and Alte Oldenburger. This highlights that even in a growing market, competitive pressures and consumer choice lead to shifts among providers.
The Winners: Top Gainers in the Supplemental Insurance Boom
The growth story is dominated by clear winners who successfully attracted new customers. These insurers capitalized on the rising demand for enhanced coverage. The top gainers by absolute numbers of new insured persons were:
- Barmenia: The clear champion, adding a remarkable 112,017 new persons to its supplemental insurance portfolio.
- Münchener Verein: Secured second place with a gain of 81,657 persons.
- Gothaer: Took third place, growing by 59,249 persons.
Other significant gainers included Hallesche (+57,616), ERGO (+56,138), Union (+54,384), Allianz Private (+51,277), R+V (+45,420), Generali Deutschland (+36,401), and Nürnberger (+21,580). This list demonstrates where consumer trust and attractive product offerings converged in 2020.
Market Leaders: Who Holds the Largest Supplemental Customer Base?
Market share is about both growth and total size. The largest providers by total number of insured persons in supplemental coverage are the established giants, though their growth rates vary. Understanding who the market leaders are can inform your assessment of stability and service network.

|---|---|---|---|
| 1 | DVK (ERGO Group) | 3,576,052 | +1,669 |
| 2 | Allianz Private | 2,174,776 | +51,277 |

Key Takeaways and US Market Parallels
What does this mean for you as a consumer? The strong growth in supplemental insurance underscores a universal truth: basic health coverage often isn't enough. People are proactively seeking financial protection and better access for specific needs.
For US Readers: A Helpful Analogy
The German supplemental insurance (Krankenzusatzversicherung) market functions similarly to key segments of the US insurance landscape:
- Like Medigap (Medicare Supplement): It fills the gaps in core coverage (e.g., GKV co-payments, similar to Medicare deductibles and coinsurance).
- Like Dental/Vision Insurance: It often provides specific benefits for areas not fully covered by basic plans.
- Like Hospital Indemnity or Critical Illness Plans: Some German supplements offer cash benefits for hospital stays, mirroring US ancillary products.
The trends in Germany—where consumers are actively shopping for add-ons—are directly reflected in the US, where millions enroll in Medigap or separate dental plans to complement their Medicare or employer-sponsored insurance.
Actionable Insight for Your Coverage Review
When reviewing your own health insurance, consider these questions inspired by the 2020 market data:
- Are there gaps in my core coverage? (e.g., dental, vision, alternative therapies, private hospital room).
- Does my current insurer have a strong track record in the supplemental market? The winners' list can indicate companies with competitive and customer-focused products.
- Is my supplemental coverage still competitive? Market growth often spurs innovation and better terms. It may be time to compare your existing policy with new offerings.
The dynamic between stagnant core markets and booming supplemental sectors is a global phenomenon. By understanding which insurers are leading in growth and customer acquisition, you can make more informed decisions to build a health insurance portfolio that truly meets all your needs, whether you're in Germany, the United States, or elsewhere.
