Aggregated Claims Series

This Note provides codebooks for two data files from the Health Insurance Experiment (HIE), a large social experiment conducted by The RAND Corporation from 1974 to 1982 under a grant from the U.S. Department of Health and Human Services. The individual-episode file describes each treatment episode experienced by an HIE enrollee in terms of type, duration, provider, expenses, and effect on meeting the annual deductible or expense limit. The annual-episode file totals the number of episodes and their expenses by type during each year an individual was enrolled in the experiment. The Note describes each variable in the files, defines the response codes or range of values, and tabulates important statistics or response frequencies.
