Abstract :The health care systems are quickly adapting digital health records, which will exponentially increase the quantity of medical data. The systems are generally faced with unsustainable costs and large volumes of electronic medical data. Therefore, more efficient research, practices, and real-world applications are needed to take advantage of all benefits of medical data. One strategy to cut back on the rising costs is the detection of fraud. In this paper, XGBoost, which is an implementation of gradient-boosted decision trees, was employed, along with supervised algorithms to include Random Forest, Logistic regression, and decision trees. The List of Excluded Individuals/Entities insert ignore into journalissuearticles values(LEIE); database, which contains excluded providers\` information, was used to label as a fraud in the Medicare Part B dataset. Thus, the data has become available for use with supervised methods. According to the experimental results, the XGBoost algorithm outperformed traditional machine learning algorithms in terms of performance.
