The Society of Actuaries: Predicting High-Cost Members in the HCCI Database


Using the Health Care Cost Institute (HCCI) database, which contains claim information on approximately 47 million members annually over a seven-year time period, we examined which characteristics best predict and describe high-cost members. We found that cost history, age, gender and prescription drug coverage are all predictors of future high costs, with cost history being the most predictive.
