Switching from Private Health Insurance (PKV) back to Public Health Insurance (GKV): Possibilities and Requirements

This article discusses whether and how a return from Private Health Insurance (PKV) to Public Health Insurance (GKV) is possible.

It examines the specific requirements and scenarios that allow for such a switch and the consequences (e.g., financial disadvantages) associated with it. The text debunks the myth that such a change is fundamentally impossible.

Basics: The Dual Health Insurance System in Germany

The GKV is based on the principle of solidarity. This means that medically necessary services are provided appropriately for all insured individuals, while contributions are income-dependent, based on the individual's economic capacity. Funding is through a pay-as-you-go system where current income is used to cover current service expenses. Unlike the PKV, no funded provisions for old age are made. Services are financed by the entire membership.

The scope of services in the GKV is legally regulated in the Fifth Book of the Social Code (SGB V) and is uniform for all insured individuals. According to § 12 SGB V, services must be "sufficient, appropriate, and economical." The legislator has the option to adjust this service catalog. The remuneration of medical services in the GKV system is also regulated by budgets, which serve to control overall healthcare expenses.

Contributions to the GKV are income-dependent and are levied up to the respective contribution assessment ceiling (BBG). For voluntarily insured individuals, other types of income such as rental, interest, and lease income may also be used for contribution calculation, in addition to employment income. The financing of the system is supplemented by government subsidies. Total expenses of statutory health insurance funds are projected to be around 341.4 billion euros for 2025. For pensioners, the contribution amount is also income-dependent; in addition to the statutory pension, other income such as company pensions or capital payments may be considered for calculation.

Private Health Insurance (PKV)

The PKV is based on the equivalence principle, where the contractually agreed-upon services and the contributions calculated based on individual risk are in proportion. The contribution amount depends on the chosen tariff, the age of entry, and the health status at the time of contract conclusion. A key feature of the PKV is the creation of provisions for old age. These are factored into the premium and are intended to compensate for the increasing healthcare costs in old age.

In the PKV, the scope of services is determined by the individual tariff choice. The agreed-upon services are contractually guaranteed and cannot be unilaterally reduced by the insurer. Insured individuals generally have free choice among doctors and hospitals, including private clinics. Billing is based on the reimbursement principle: the insured individual receives an invoice for the service provided, which they initially pay and then submit to their insurer for reimbursement.

Contributions in the PKV are independent of income. Premium adjustments are foreseen to maintain long-term stability between income and expenses. Triggering factors for such adjustments can include rising healthcare costs, changes in life expectancy, or general interest rate developments. These adjustments are subject to legal regulations and are not made due to an individual's aging process.

Requirements for Returning to GKV

A switch from the PKV back to the GKV is generally possible up to the age of 55 under certain conditions. From the age of 55 onwards, re-entry into the compulsory insurance of the GKV is generally no longer provided for, unless one has not been insured in the GKV for the last five years and has been exempt from insurance for at least 2.5 years of that period. This means that the door to the GKV is usually closed after 55.

The return to the GKV occurs when compulsory insurance in the GKV is established. This can happen in various life situations:

Reduction of Salary Below the Annual Income Threshold (JAEG)

For employees whose income exceeds the JAEG, compulsory insurance in the GKV ceases. However, if an employee's gross income falls below the JAEG, compulsory insurance in the GKV generally resumes. The JAEG is adjusted annually. In 2024, it was 69,300 euros (5,775 euros per month), and it is expected to be 73,800 euros (6,150 euros per month) in 2025. If the JAEG is exceeded during the year (e.g., due to a salary increase), compulsory insurance in the GKV ends at the end of the calendar year in which it is exceeded, provided the income also exceeds the JAEG for the following year. In the event of a change of employer or a part-time arrangement, a forward-looking assessment of regular income for the next 12 months is made. If this falls below the JAEG, compulsory insurance takes effect immediately. A short-term reduction, for example, due to short-time work, generally does not lead to compulsory insurance.

Exemption from Compulsory Insurance: If compulsory insurance takes effect, an exemption can be applied for within three months of the start of compulsory insurance, provided that there was previously five years of continuous coverage in the PKV. However, if a new compulsory employment is taken up by individuals under 55 years of age, there is no possibility of exemption.

Transition from Self-Employment to Employment with Lower Income

If a previously self-employed individual who was privately insured takes up compulsory employment with a salary below the JAEG, their PKV membership ends, and compulsory insurance in the GKV begins.

Note for Start-ups: In the GKV, contributions are initially set provisionally based on expected income, but at least on the basis of a theoretical minimum income (e.g., 1/3 of the reference amount, approx. €1,235.85 from 2025). After submission of the income tax assessment, a retroactive, final contribution assessment is made based on the actual income earned, which may result in refunds or additional payments. For example, a gross annual profit of €30,000 (approx. €2,500 per month) can lead to an additional payment of over €3,000 per year.

Unemployment for Individuals Under 55 Years of Age

Receiving unemployment benefits can lead to compulsory insurance in the GKV. Here too, the option to apply for an exemption within three months exists if there was previously five years of continuous PKV coverage.

Entitlement to Family Insurance

The GKV generally offers contribution-free family insurance for spouses and children under certain conditions. Children can be co-insured free of charge until they are 18 years old (generally), 23 years old (if not gainfully employed), or 25 years old (if in school or vocational training). A spouse is co-insured free of charge if they have no or only minimal income of their own (e.g., up to a maximum of €556/month).

However, there is a crucial restriction: if both parents are married and one parent is privately insured and regularly earns above the JAEG, while the other parent is insured in the GKV, children must pay their own contribution to the GKV if the privately insured parent has a regularly higher income than the GKV-insured partner. If this is not the case, contribution-free family insurance in the GKV may apply. In the PKV, each family member pays their own premium. However, premiums for children are significantly lower than for adults, as no provisions for old age need to be built up for them (only from age 21).

Beginning of Studies

Upon enrollment, compulsory insurance in the GKV begins, even for students previously insured in the PKV. However, there is an option to apply for an exemption within three months of compulsory insurance taking effect with the last GKV. If the three-month period has passed, there is no possibility of exemption.

Implications of Switching from PKV to GKV

One aspect of switching from PKV back to GKV concerns the provisions for old age. These funds, accumulated within the PKV contract, are used to stabilize premiums in old age. If you return to the GKV, these provisions for old age cannot be transferred to the statutory system and remain with the private insurer.

Within Private Health Insurance, various mechanisms exist that can affect premium levels in old age. These include the scheduled elimination of the statutory surcharge from the age of 60 and the premium for daily sickness allowance upon retirement. Furthermore, surplus participation can affect premiums, and there is the option to provide for guaranteed premium reductions in old age through special premium reduction tariffs. Additionally, insured individuals have a statutory right to change tariffs (§ 204 VVG), which allows switching to other tariffs within their own company while retaining their provisions for old age.

In the event of financial need, the PKV system provides for the legally regulated basic tariff. Its services are comparable in type, scope, and amount to those of the GKV. The premium for this tariff is capped at the maximum GKV contribution. In cases of proven need, the premium can be reduced or fully covered by social benefit providers.

Recommendations & FAQ

For individuals considering a switch from PKV back to GKV, a careful assessment of their individual situation is crucial.

Checklist for a Possible Switch:

Check Age Limit: Are you under 55 years old? The age limit is a strict cutoff.
Evaluate Income Situation: Does your regular income fall below the currently applicable Annual Income Threshold (JAEG)? Consider the forward-looking assessment for 12 months in cases of job changes or part-time employment.
Analyze Family Situation: Are you entitled to contribution-free family insurance in the GKV, and do you meet the income requirements, especially if a partner is privately insured?
Assess Long-Term Cost Development: Compare the expected premium development in the GKV (which depends on wage development and politics) with that in the PKV, which is stabilized by provisions for old age. Consider the loss of provisions for old age when switching to the GKV.
Examine Alternatives within PKV: Have you explored all options for changing tariffs within your PKV to reduce premiums or adjust the scope of services without losing your accumulated provisions for old age?

Frequently Asked Questions (FAQ):

Can the insurer terminate the contract due to illness?
No, in full-cost health insurance, termination by the insurer due to an illness that has occurred is legally and contractually excluded. Likewise, individual premium increases due to newly occurring illnesses are not permissible. The risk of illness is taken into account in the initial premium calculation.
How do premium adjustments work in PKV?
Premium adjustments are subject to clear legal regulations. They are made for an entire tariff collective when general factors such as the cost of medical treatments, average life expectancy, or the interest rate change. An individual's aging process or health status are not reasons for a premium adjustment. A portion of the premium is used from the start of the contract to build up provisions for old age, which finance the generally age-related increase in healthcare costs.
What happens to the provisions for old age when switching to GKV?
The provisions for old age built up in the PKV are not transferable when switching to the GKV. They cannot be taken into the statutory system or paid out to the insured individual.
What is the function of the basic tariff in PKV?
The basic tariff is a legally defined tariff option in PKV. Its scope of services is comparable to that of the GKV, and the premium is capped at the maximum GKV contribution. For individuals with proven need, the premium can be reduced or covered by social benefit providers.

Final Note: For an individual and informed decision, it is advisable to seek qualified advice to clarify personal circumstances and the long-term financial implications of both systems.

Summary

Switching from Private Health Insurance (PKV) back to Public Health Insurance (GKV) is subject to statutory requirements. A key condition is the age limit of 55; for individuals over this age, a return is only possible in exceptional cases. A switch also requires the onset of compulsory insurance in the GKV, for example, through a reduction of income below the Annual Income Threshold (JAEG).

When switching systems, the provisions for old age accumulated in the PKV are not transferred to the GKV system. Alternatively, the PKV offers the option to adjust premiums and benefits internally through a tariff change, thereby preserving the provisions for old age. The decision for either path should be based on an analysis of the personal situation and long-term implications.
