Claims Line-Item Series

The codebooks in this volume describe the contents of 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 codebooks document service and charge information collected in the "line items" of HIE insurance claim forms submitted by providers or HIE participants for fee-for-service medical and dental services, drugs, and supplies. This primary-variable information has been categorized into 14 files — by type of medical or dental service rendered — to facilitate study of the use and costs of such services in the fee-for-service sector.
