As a civil servant, you already enjoy a certain level of health coverage through the assistance provided by your employer. But what about the costs that are not covered by this assistance? This is where the supplementary health insurance comes in, ensuring comprehensive protection.

The topic in brief and concise terms

The supplementary health insurance is a private health insurance that covers the healthcare costs for civil servants and their families that are not covered by the state aid.

The amount of allowance varies depending on the employer (federal/state), marital status, and number of children, usually between fifty and eighty percent.

An assistance insurance is essential to close gaps in coverage and ensure comprehensive medical protection.

The Allowance Insurance: Key Facts for Civil Servants at a Glance

The assistance constitutes a welfare benefit provided by the employer, covering a portion of the medical, nursing, and maternity costs for civil servants and their eligible dependents. Typically, the assistance covers between fifty and eighty percent of the incurred costs. To cover the remaining twenty to fifty percent, a private assistance insurance is necessary. This supplementary insurance is thus a key component in the healthcare provision for civil servants. Without it, civil servants would need to bear a significant portion of treatment costs themselves, which could quickly lead to a financial burden amounting to several thousand euros. The assistance insurance fills this gap, ensuring comprehensive medical care.

How the supplementary insurance works and its necessity in practice

The assistance provided by the employer, depending on marital status and federal state, often only covers part of the healthcare costs, for instance, fifty percent for the civil servant themselves. The remaining fifty percent of doctor or hospital costs must be covered elsewhere. This is where the private supplementary insurance comes in. It reimburses the difference, so ideally, one hundred percent of the eligible costs are covered. For example: If a doctor's bill amounts to four hundred euros, the assistance covers two hundred euros at a rate of fifty percent; the supplementary insurance pays the other two hundred euros. Many civil servants initially underestimate the necessity of this supplement. The cost of a private health insurance is usually cheaper for civil servants due to the assistance than a full insurance.

The assistance, and thus also the supplementary insurance, applies not only to the civil servant themselves, but often also to their spouse and children, provided that certain income limits and conditions are met. For children, the assistance rate is often eighty percent. The remaining twenty percent must then be covered by supplementary insurance for the child. There is no family insurance like in statutory health insurance in the private supplementary insurance; each family member requires their own policy. This ensures individual and needs-based coverage for the entire family. The exact regulations for applying for benefits can be complex.

In-depth insights: Legal foundations and individual tariff design

The legal foundations of the allowance are laid down in the Federal Aid Regulations (Bundesbeihilfeverordnung - BBhV) and the regulations of the individual federal states. These regulations detail which expenses are eligible for aid and to what extent. It's important to know that the aid regulations may vary between the federal government and states, as well as between the states themselves. This includes, for example, the level of aid rates or the recognition of certain services, such as optional hospital services (single or double room, chief physician treatment). Our expert tip: Before taking out an aid insurance policy, carefully review the aid regulations applicable to you. A good private health insurance for civil servants takes these differences into account.

When choosing your aid insurance, you should look for tariffs that are precisely tailored to your individual aid rate and needs. The following aspects are relevant when choosing a tariff:

  • Coverage of optional hospital services: Not all aid providers fully reimburse these costs.

  • Reimbursement for visual aids and dental prostheses: There are often maximum amounts set by the aid.

  • Services for alternative healing methods: Recognition can vary greatly.

  • Premium stability in old age: Look for well-calculated tariffs.

  • Possibility of premium refunds in the absence of claims.

Careful selection ensures you long-term optimal care and protection against unexpected costs. The advantages of private insurance can fully come into play here.

The role of supplementary health insurance in the overall care concept

The supplementary insurance is more than just a complementary insurance; it is an integral part of the healthcare system for civil servants. Without it, the aid system would be incomplete and would expose many civil servants to significant financial risks. Health and long-term care coverage through the combination of aid and supplementary insurance usually provides high-quality insurance protection. This often includes benefits that exceed the level of statutory health insurance, such as the free choice of doctors and hospitals or shorter waiting times for specialists. Thus, the supplementary insurance ensures access to comprehensive medical care.

It is also important to consider coverage in the case of long-term care. While aid also provides benefits in the event of long-term care, it usually only covers part of the costs here as well. A private supplementary long-term care insurance, often offered in combination with the supplementary insurance, can be an important addition. Also consider disability insurance for civil servants to protect your income in the event of an inability to work. Thus, supplementary insurance is a component of a comprehensive precautionary concept. Understanding the basics of health insurance is helpful here.

Flat-rate assistance as an alternative: What civil servants need to know

In some federal states (e.g. Hamburg, Berlin, Bremen, Brandenburg, Thuringia, and since 2023 also Baden-Württemberg and Lower Saxony), there is, in addition to individual aid in conjunction with private aid insurance, also the option of flat-rate aid. In this case, civil servants receive a monthly subsidy for their statutory or private health insurance amounting to fifty percent of the contribution. This option can be an alternative for some civil servants, particularly if pre-existing conditions make it difficult or very expensive to obtain private aid insurance. The decision for the flat-rate aid is usually binding and should be carefully considered.

There are some important points to note with the flat-rate aid:

  1. The subsidy is limited to half of the actual insurance contribution.

  2. Family members are not automatically insured and require their own solutions.

  3. The scope of services is based on the chosen statutory or private health insurance tariff, not on the aid regulations.

  4. A later switch back to the individual aid system is often not possible or only with difficulty.

Therefore, carefully consider which form of coverage is better for your individual situation and family planning in the long term. The public sector pension scheme is another topic that deserves attention.

Optimizing Your Coverage: Tips for Choosing the Right Supplementary Health Insurance

Choosing the right supplementary health insurance requires a thorough analysis of your personal situation and the applicable aid provisions. Don't just focus on the price, but especially on the package of benefits. A plan should at least cover the services that your aid office does not fully or only partially provide. Compare offers from at least three different insurers. Our expert tip: Use independent comparison portals or seek advice from specialized consultants.

Important criteria for your decision are:

  • Reimbursement rates for outpatient, inpatient and dental treatments.

  • Provisions for aids, remedies and psychotherapy.

  • Coverage of preventive examinations beyond the aid level.

  • Service quality of the insurer, for example, prompt reimbursement and good accessibility.

  • Options for adjusting premiums in old age, such as ageing reserves.

A well-chosen supplementary health insurance provides you with security and protects you from high healthcare costs, also with regard to the health insurance for pensioners. nextsure is happy to assist you in selecting the optimal protection.

FAQ

What does the supplementary health insurance cover in detail?

The supplementary health insurance usually covers the costs of outpatient, inpatient, and dental treatments that remain after deducting the subsidy benefits. The exact range of benefits depends on the chosen tariff and should be tailored to the individual subsidy regulations.

Are my family members automatically insured?

No, in supplementary health insurance, there is no automatic family co-insurance like in the statutory health insurance (GKV). A separate contract must be concluded for each family member eligible for benefits (spouse, children), which covers the remaining costs according to their individual benefit rate.

What happens when changing the employer or federal state?

Since the subsidy regulations can vary depending on the federal state, the insurance coverage of the subsidy insurance should be reviewed and adjusted if necessary when changing employers or moving to another federal state, to avoid coverage gaps.

Are there alternatives to the traditional subsidy with private subsidy insurance?

Yes, in some federal states, there is the option of a flat-rate allowance. In this case, civil servants receive a subsidy for their statutory or private health insurance. This decision is usually binding and should be carefully considered.

How do I find the right supplementary health insurance?

To find the right supplementary health insurance, you should compare offers and pay attention to benefits that meet your individual needs and the specific regulations of your employer. Independent advice can be very helpful in this regard.

What is the difference between allowances and healthcare support?

Subsidy is a grant towards medical expenses. Health care, on the other hand, is a complete coverage of medical expenses by the employer, granted to specific professions such as police officers or soldiers during their active service. In retirement, recipients of health care typically switch to the subsidy system.
