The new risk adjustment formula in Germany: Implementation and first experiences

In Germany risk adjustment is a core element of the regulatory framework of competition between sickness funds. It shall create a level playing field between funds with very heterogeneous risk structures. Prior to 2009 risk adjustment was mainly by a demographic model. In 2009 morbidity based risk adjustment was introduced, embedded in a broader reform of the statutory health insurance system. The new formula covers 80 “severe” or “costly and chronic” diseases structured in a system of hierarchical groups.
