What are supplementary health insurances?
If you are in the public health insurance (GKV) you have the option to enhance your coverage in a variety of ways. The reason is that there are many gaps in coverage, such as only partial payment for dental work, shared rooms in the hospital, no visual aids coverage and many more.
Furthermore, the GKV is subject to the so-called “economic efficiency principle”, they are simply not allowed to pay for everything / for the high quality materials. The measures they take must correspond to the extent of what is necessary and must therefore be "sufficient, appropriate and economical".
These gaps have gradually been filled with private supplementary insurances, meant to give you the opportunity to get the coverage that you want.
What types of supplementary health insurances exist?
The types of supplementary health insurances mirror the basic build-up of health and nursing-care insurance in Germany:
- In-patient treatment: mostly hospital stays and your treatment in one.
- Out-patient treatment: everything ranging from visual aids to preventative measures and homeopathic treatment. The variety here is great.
- Dental care: more reimbursement for extensive dental work, teeth cleaning and overall better materials & services.
- Nursing-care: mostly receiving more money when you need it the most.
In 2021 the dental insurances alone had nearly 18 million members, showing how far these kind of insurances are in usage in Germany.

What does In-patient supplementary health insurance (“Stationäre Kranken-Zusatzversicherung”) do?
If you have to be treated in a hospital, GKV only covers your basic costs, you will be accommodated in a multi-bed room and be treated by the attending physician. Furthermore, you have to go to the nearest suitable hospital, not necessarily the best one.
You can read the expanded guide about In-Patient supplementary health insurance here.
There are two in-patient add-ons you can take out:
1. Supplementary hospital insurance (“Krankenhaus-Zusatzversicherung”)
With this you are mainly buying:
- Free choice of hospital
- Private room
- Head physician treatment, i.e. free choice of treating doctor
- And a few small benefits
The premiums depend on
a) your age and b) the scope of coverage but here a rough overview:
| Age | Average monthly premium with old-age reserve (i.e. the premium stays the same) | Average monthly premium without old-age reserve (i.e. the premium increases over the years) |
|---|---|---|
| Children | 5 € – 10 € | – |
| 20 | 30 € – 40 € | 10 € – 20 € |
| 30 | 40 € – 50 € | 20 € – 30 € |
| 40 | 50 € – 60 € | 30 € – 40 € |
| 50 | 60 € – 70 € | 40 € – 50 € |
2. Hospital daily cash (“Krankenhaustagegeld”)
- The benefit here is simple: Money.
- You can choose an amount of money you receive for every day that you are in a hospital, so that longer hospital stays do not drain your finances.
- The premium of course depends on how much money you want to receive:
| Age | Daily Cash | Average monthly premium |
|---|---|---|
| Children | 25 € | 1,50 € |
| 50 € | 3 € | |
| 20 | 25 € | 3 € |
| 50 € | 6 € | |
| 30 | 25 € | 5 € |
| 50 € | 10 € | |
| 40 | 25 € | 7 € |
| 50 € | 15 € | |
| 50 | 25 € | 10 € |
| 50 € | 20 € |

What does Out-patient supplementary health insurance (“ambulante Kranken- Zusatzversicherung”) do?
This type of add-on is a little bit more elusive as the coverage can differ greatly, with some policies only giving you money in case you need glasses and some policies covering the whole field.
However, there are the things that you can get, you just need to let us know what you are looking for:
- Alternative practitioners: Most GKV-carriers do not cover anything that goes beyond “traditional” modern medicine. Adding the alternative practitioners module gives you coverage for treatments such as osteopathy, homeopathy, acupuncture and traditional Chinese Medicine. In most cases, the add-on lets you spend a set amount each year on these treatments.
- Visual aids: GKV only contributes to the cost of glasses etc. for adults if they have a severe visual impairment. This add-ons, similar as above, enables you to spend a given amount of money per year for glasses, contact lenses, eye laser surgery (Lasik), etc.
- Preventative measures: the ministry of health gives very specific guidelines about what is covered and when you want more than that, you have to pay for them yourself.
The premium naturally depends on the scope of coverage, but to give you a broad idea:
| Age | Average monthly premium |
|---|---|
| Children | 10 € - 17 € |
| 30 | 15 € - 30 € |
| 40 | 20 € - 40 € |
| 50 | 30 € – 50 € |
What does dental supplementary health insurance (“Zahn-Zusatzversicherung”) do?
Private supplementary dental insurance reimburses the costs of dental treatment that is not or only partially covered by GKV. If e.g. a tooth has to be replaced, GKV generally only pays 60 % of the costs for standard care and you can top these 60 % up to 80 %, 90 % or 100 %.
You can read the expanded guide about Dental supplementary health insurance here.

Standard care means (and it is written into law) that the treatments covered by public health insurance need to be “economical, appropriate and satisfactory”, which means: they need to get the job done and not much more. In practice this means the cheapest material for fillings, no ceramic for crowns, no teeth cleaning, etc. If you are in GKV and want better materials, you have to pay for it yourself, unless you have such a supplementary dental insurance.
There are four main pieces of coverage:
- Dentures (Zahnersatz): implants, bridges, crowns, inlays, dentures, veneers etc.
- Dental treatment: things such as high quality fillings and root canal treatments.
- Preventative measures: teeth cleaning, prophylaxis, bleaching and more.
- Orthodontic services: such as braces for children and adolescents.
The table below shows you a few examples of dental costs and the regular reimbursements:
| All-ceramic crown | Dental implant | Synthetic filling | Teeth cleaning | |
|---|---|---|---|---|
| Costs | 800 € | 2.500 € | 100 € | 120 € |
| GKV payment | 162 € | 375 € | 50 € | 0 € |
| Costs without add-on | 638 € | 2.126 € | 50 € | 90 € |
| Costs with add-on | 0 € - 80 € | 0 € - 250 € | 0 € - 10 € | 0 € |
The costs of treatment naturally need to keep in balance with the costs for such insurances:
| Age | 80 % reimbursement | 90 % reimbursement | 100 % reimbursement |
|---|---|---|---|
| Children | 5 € - 10 € | 10 € - 15 € | 15 € - 25 € |
| 20 | 10 € - 15 € | 15 € - 25 € | 20 € - 25 € |
| 30 | 15 € - 20 € | 20 € - 25 € | 25 € - 35 € |
| 40 | 20 € - 25 € | 25 € - 35 € | 35 € - 45 € |
| 50 | 25 € - 35 € | 35 € - 45 € | 45 € - 55 € |
What does nursing-care supplementary health insurance (“Pflegeversicherung”) do?
More and more people are dependent on professional care in old age but also more often when younger now, e.g. due to illnesses. Adequate care can be very expensive and the public nursing-care insurance (“Pflegepflichtversicherung or PVN”) helps to finance only the partial costs.
You can read the expanded guide about Nursing-care supplementary health insurance here.

How much the PVN exactly pays is determined by a number of factors ( the state you live in, the degree of care needed, whether it is in-patient or out-patient, etc.), however, it does not even remotely cover the entire costs and there always are costs that the patient has to pay herself.
There are three types of nursing-care add-ons:
- Daily cash: you receive a given amount of money for each day you need care.
- Nursing costs insurance (“Pflegekostenversicherung”): Covers the gap between what the PVN pays and what the actual costs are.
- Nursing pension Insurance: Similar to a private pension plan, you will receive a guaranteed, lifelong pension if you are in need of nursing care.
