Cover Story: Neural networks are currently transforming health insurance pricing. While machine learning is well established in property and casualty insurance, its application to health coverage remains largely underexplored. This study presents a novel approach using negative multinomial neural networks to model correlated medical claims and Gamma neural networks to predict claim severity. Tested on real-world data, the framework outperforms traditional accuracy and risk segmentation methods, enhanced by explainable AI (XAI) for transparency. View this paper
