Intergenerational solidarity is not only practised in health insurance but also between the individual health insurers in the form of risk equalisation. How does this equalisation work?
In simplified terms, risk equalisation transfers money from health insurers with many young, healthy and thus inexpensive insured persons to health insurers who insure more older people who incur higher costs. Risk equalisation was initially introduced in 1993 as a temporary measure and aimed to curb the «hunt» for young, low-cost insured persons – so-called risk selection. In 2014, risk equalisation was anchored in law. Since its introduction, it has been continuously fine-tuned on the basis of findings provided by the CSS Institute. Whereas the only criteria that counted at the beginning were age and gender, other factors were gradually taken into account, such as whether a person was treated in a hospital and the amount of medication costs they incur.
