Rising fees in private health insurance based on a three-point regression
Fees for private health insurance in Germany are regularly subject to revision. Because these fees often increase significantly, many individuals are suing their insurance companies. In such proceedings, court-appointed experts must assess whether the fee adjustment was permissible and, if so, whether the amount of the increase was justified.
A fee revision may and must be reviewed if in the last three years, the ratios of projected to actual claims show a sustained deviation, and if a regression analysis of these three ratios forecasts a future value that deviates by at least 10% (the so-called “trigger factor”).
In addition to the revision mechanism itself, numerous actuarial components influence the fee calculation, including interest rates, mortality tables, lapse tables, retirement reserves, fee caps, costs and security reserves. The sheer number of tariffs, combined with the flexibility inherent in the underlying actuarial methodology such as the three-point regression, creates opportunity for methodological choices that may affect the outcome.
