    Abstract

    Efficient insurance fraud management can have significant effect on insurance companies’ competitive market position. Potential savings accumulated in fraudulent activities can add up to 10% of all expenses insurance companies pay for damage claims, which globally add up to several 100 billion Euros. There are various available methods to detect insurance fraud. The simplest one, that is to manually review a small number of insurance claims, is highly inefficient and its success rate is largely dependent on investigator’s luck to select the exact cases that would turn out fraudulent after investigation. It is more efficient for investigators to use information technology that systematically highlights all cases which are identified as suspicious by predetermined criteria. Thereby, the investigators can focus solely on the potentially interesting cases. The implementation of fraud management information system into the business system of an insurance company also demands measuring the effects of such a system on its business performance. These effects can be divided into two categories: direct and indirect. The direct effects relate to quantity, value and the relevance of detected frauds, while the indirect effects give an estimation of fraud prevention effectiveness among individuals who are most likely to commit fraud. Direct effects can be measured and directly taken into account when calculating insurance company’s business success. Indirect effects, however, cannot be measured this way for most insurance lines. A high level of fraud diversification and randomness is hard to encapsulate into prediction models, especially those capable of forming estimates with an sufficient degree of confidence to be included in the insurance company’s savings estimates. However, the assessment of indirect savings is to a certain extent feasible in some insurance lines where the number of potential fraudsters is limited and relatively small. For such cases, it can be presumed that once fraudulent activity is detected and sanctioned, it will no longer occur or it will occur to a lesser extent. In fore mentioned systems assessment can be made on the basis of the differences in the dynamics of occurring suspicious fraud cases. An example of such insurance line is health insurance. The result of the master’s thesis is an extended assessment method which can be used to evaluate the performance of health insurance fraud management systems. The method takes into consideration both the direct savings and the assessment of indirect effects which occur as a result in the systematic fight against fraud. With the help of the suggested method the health insurance companies gain not only a full overview of the success and efficiency of the fraud management processes but also an assessment of how these influence the business performance of an entire insurance company.
