The German health insurance system consists of the statutory health insurance (GKV) and private health insurance (PKV). About 85% of Germans are members of statutory health insurance, while about 15% of the insured with a private health insurance signed on, because they meet the so-called shooting conditions. Both insurance companies differ, inter alia through its billing procedures, their achievements and their contributions. In a contract with a private health insurance the insured person pays an individual contribution plus 10% for retirement provisions, while in the statutory health insurance contributions from each insurance company are the same and also no age provisions are made.
