Aggregated Claims Series: Volume 2: Codebooks for Fee-for-Service Visits — Outpatient, Inpatient, and Dental
Jan 1, 1986
This codebook describes the contents of a data file 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 fee-for-service (FFS) annual expenditures and visit counts file documents yearly health care expenditure and visit totals for each HIE participant who used private, fee-for-service medical or dental care during the course of the HIE. Only FFS usage by FFS participants is presented, with one exception: FFS dental usage data for HIE participants enrolled in a health maintenance organization are included in the dental expenditures and visit counts.
