        pending on health care has grown rapidly in recent decades and has
 S      placed increasing pressure on both private and public budgets. The
        House Committee on Ways and Means has asked the Congressional
Budget Office (CBO) to study the economic and budgetary costs of the rapid
rise in national health care expenditures. CBO1s response is in two parts.
This study reviews the growth in national health spending since 1965and pro-
vides projections through 2000. A companion study, Economic Implications of
Rising Health Care Costs, examines the implications of providing health
insurance through an employment-based system and the effects of the rising
costs of federal health programs on the economy. In keeping with CBO1sman-
date to provide impartial analysis, the studies make no recommendations.

    This report was written by Jeffrey Lemieux of CBO1s Budget Analysis
Division and Christopher Williams of the Fiscal Analysis Division, under the
direction of Robert Dennis, C.G. Nuckols, Charles E. Seagrave, and Paul N.
Van de Water. Mr. Williams was primarily responsible for Chapter 1 and
Appendix B, and Mr. Lemieux was the principal author of Chapters 2 through
4 and Appendix A.

NOTES:       "Use per person" and "Other price and intensity" are net of predicted impacts on use and intensity from changes in
             demographic composition. CBO has no measure of demographic composition effects for some smaller types of health
             spending and no independent use or volume measures for some types of spending. In these cases, CBO has approximated
             the demographic and use contributions to personal health expenditure growth using data from similar types of spending.

 SOURCES:   Joint Committeeon Taxation; Officeof Management and Budget; and Congressional Budget Office.
 NOTE:   The Congressional Budget Office uses tax expenditure estimates based on projections of the Joint Committee on Taxation
         (JCT) published annually in "Tax Expenditure Estimates By Budget Function." CBO converts these to a calendar-year basis
         and extrapolates them through 2000 based on CBO's projections of health spending. Until the mid-1980s, JCT estimates were
         identical t o those of the Office of Management and Budget (OMB) as published in The Budget o f the United States. The
         OM0 estimates provide an additional year o f revision and therefore are used for historical data where appropriate. The sum
         of the estimates reported here may differ from the actual revenue gain by eliminating all the individual tax expenditures
         because of interaction effects.
