Introduction
In several countries fraudulent behavior in health insurance is a major problem. Data mining tools and techniques can be used to detect fraud in large sets of insurance claim data. One of the most common data mining techniques used for finding fraudulent records is anomaly detection.
Conclusion
In conclusion, this paper reviews two approaches for detecting fraudulent behavior in health insurance claim. By analyzing the aforementioned techniques, we will get a clear idea for the future work in health insurance claim fraud detection. In India, we have three levels of health care network, namely primary, secondary, and tertiary. It provides an opportunity for data miners to use the huge amount of data. The main task is to integrate data from different sources and then put to use by data miners to achieve the desired results.
