Mitversicherung

What Is Mitversicherung?

Mitversicherung, often translated as "co-insurance" or "co-insurance clause," is a fundamental concept within the Versicherungswesen that requires the policyholder to share a percentage of the costs of a covered loss with the insurer after the Selbstbehalt (deductible) has been met. This mechanism ensures that both the insured and the insurer have a financial stake in the outcome of a Schadenfall, promoting shared responsibility and discouraging excessive claims. Mitversicherung is designed to reduce moral hazard and align the interests of the policyholder with those of the insurance company. It appears across various types of insurance, from health policies to property and casualty coverage, representing a common form of Risikomanagement.

History and Origin

The concept of cost-sharing in insurance, which includes Mitversicherung, has roots in the evolution of modern Versicherungsvertrag structures. Early forms of insurance often involved basic risk pooling, but as policies became more sophisticated, mechanisms to manage policyholder behavior and financial incentives emerged. In the United States, particularly within healthcare, the impact and design of co-insurance and other cost-sharing measures gained significant academic attention with studies like the RAND Health Insurance Experiment. Conducted between 1974 and 1981, this large-scale experiment provided crucial insights into how different levels of cost-sharing, including various co-insurance rates, influenced healthcare utilization and spending. The findings from this experiment continue to be considered a benchmark for understanding the effects of cost-sharing on medical expenses and consumer behavior.¹²

Key Takeaways

• Mitversicherung requires policyholders to pay a specified percentage of covered losses after the deductible.
• It serves as a cost-sharing mechanism, ensuring the insured bears a portion of the financial burden.
• This percentage varies widely depending on the type of insurance policy and the specific Deckung provided.
• Mitversicherung is distinct from a Versicherungsprämie (the regular payment for the policy) and a deductible (a fixed amount paid before co-insurance applies).
• It is a tool used by insurers to manage risk and potentially reduce claims volume.

Formula and Calculation

In property insurance, Mitversicherung (co-insurance clause) is often used to ensure that the insured maintains an adequate amount of Kapital coverage relative to the property's value. If the policyholder underinsures their property, the Mitversicherung clause can result in a penalty, reducing the amount the insurer will pay for a partial loss. The formula for calculating the reimbursement amount in such a scenario is:

Where:

• (\text{Erstattungsbetrag}) = The amount the insurer will reimburse.
• (\text{Schadenbetrag}) = The actual amount of the loss.
• (\text{Versicherungssumme}) = The amount of insurance carried (policy limit).
• (\text{Wiederherstellungswert}) = The replacement cost value of the property at the time of loss.
• (\text{Mitversicherungsquote}) = The co-insurance percentage required by the policy (e.g., 80%, 90%).

This formula applies only if the Versicherungssumme is less than (Wiederherstellungswert * Mitversicherungsquote). If it is equal to or greater, the insurer typically pays the lesser of the loss amount or the policy limit.

Interpreting Mitversicherung

Interpreting Mitversicherung involves understanding its direct impact on a policyholder's Haftung for covered services. For instance, a policy with "80/20 Mitversicherung" means the insurer pays 80% of covered costs after the deductible, and the policyholder pays the remaining 20%. This percentage sharing directly influences out-of-pocket expenses. Policies with lower Mitversicherung percentages for the policyholder generally come with higher Versicherungsprämie, reflecting the greater risk assumed by the insurer. Conversely, higher policyholder Mitversicherung can mean lower premiums but exposes the insured to greater financial responsibility in the event of a large claim. It is crucial for individuals and businesses to evaluate their risk tolerance and financial capacity when choosing policies with different Mitversicherung structures.

Hypothetical Example

Consider a health insurance policy with a €1,000 annual deductible and an 80/20 Mitversicherung provision for covered services. Suppose a policyholder incurs €6,000 in medical expenses for a procedure after meeting their deductible.

1. Deductible: The policyholder has already paid their €1,000 deductible.
2. Remaining Costs: Of the €6,000 medical bill, the first €1,000 was covered by the deductible, leaving €5,000.
3. Mitversicherung Application: The 80/20 Mitversicherung applies to the remaining €5,000.
   • The insurer pays 80% of €5,000 = €4,000.
   • The policyholder pays 20% of €5,000 = €1,000.
4. Total Policyholder Out-of-Pocket: In this scenario, the policyholder's total out-of-pocket cost for this procedure would be their initial €1,000 deductible plus the €1,000 Mitversicherung portion, totaling €2,000. The insurance company covers €4,000. This example illustrates how Mitversicherung directly impacts the financial Portfolio of the insured when a significant claim occurs.

Practical Applications

Mitversicherung is widely applied across various insurance sectors to manage shared financial responsibility. In healthcare, it is a standard feature of many health insurance plans, requiring patients to pay a percentage of their medical bills after their deductible is met, up to an out-of-pocket maximum. This helps control healthcare spending by encouraging consumers to be more mindful of costs., In property insurance, a Mitvers¹¹i¹⁰cherung clause (often 80% or 90%) ensures that homeowners insure their property for a specific percentage of its replacement cost to avoid penalties in the event of a partial loss. For example, if a home is valued at €500,000 and has an 80% Mitversicherung clause, it should be insured for at least €400,000 to receive full coverage for partial damages. This is also relevant in [liability i⁹nsurance](https://diversification.com/term/liability-insurance) and commercial insurance policies, where it distributes financial exposure between the insurer and the insured. The rising prevalence of high-deductible plans and increased co-insurance obligations has shifted a larger share of healthcare costs to consumers, impacting affordability. Regulatory bodies, such as the New Yo⁸rk Department of Financial Services, often provide guidance and information on various insurance clauses, including co-insurance, to protect consumers and ensure fair practices.

Limitations and Criticisms

While⁷ Mitversicherung aims to promote shared responsibility and mitigate moral hazard by making policyholders financially accountable for a portion of their claims, it also presents limitations and criticisms. A primary concern is the potential for significant and unexpected out-of-pocket costs for policyholders, especially with high medical expenses, even after meeting their Selbstbehalt. This can create financial strain and may deter individuals from seeking necessary medical care or making claims, which could lead to worse health outcomes or greater long-term Kosten. Critics argue that while cost-sharing reduces overall healthcare spending, it can disproportionately affect the ill, as demonstrated by aspects of the RAND Health Insurance Experiment, which explored the trade-off between risk pooling and moral hazard., Some analyses suggest that an intens⁶e⁵ focus on reducing moral hazard through high cost-sharing might obscure more effective policies for healthcare expenditure reduction and could lead to poorer health outcomes for vulnerable populations. Furthermore, the complexity of Mitver⁴sicherung calculations, especially in property insurance, can lead to Underinsurance if the policyholder doesn't accurately assess their property's value relative to the required co-insurance percentage.

Mitversicherung vs. Selbstbehalt

Mitversicherung (co-insurance) and Selbstbehalt (deductible) are both forms of cost-sharing in insurance policies, but they function at different stages of a claim. Understanding their distinction is crucial for policyholders managing their financial Planung.

In essence, the Selbstbehalt is the initial hurdle for the policyholder, while Mitversicherung represents an ongoing sharing of expenses once that initial hurdle is cleared. Both mechanisms are designed to control claims costs and share risk.

FAQs

What does "80/20 Mitversicherung" mean?

80/20 Mitversicherung means your insurance company will pay 80% of the covered costs of a service, and you will be responsible for paying the remaining 20%. This applies after you have paid your Selbstbehalt (deductible). For example, if a covered service costs €100 and your deductible is met, your insurer pays €80, and you pay €20.,

Why do insurance policies include Mitversiche³r²ung?

Insurance policies include Mitversicherung to share the financial Risiko between the insurer and the policyholder. This cost-sharing mechanism helps to reduce moral hazard, where individuals might overuse services if they bear no financial cost. By having a stake in the expense, policyholders are encouraged to make more considered decisions about their healthcare or property claims, contributing to overall Kostenmanagement.

Is Mitversicherung the same as a copayment?

No, Mitversicherung is not the same as a copayment. A copayment (or copay) is a fixed fee you pay for a specific service, such as a doctor's visit (€20) or a prescription (€10). Mitversicherung, on the other hand, is a percentage of the total cost of a service after your deductible has been paid. Both are out-of-pocket costs, but their structure and application differ.¹
