Medicaid, the uninsured, and national health spending: federal policy implications.

Implications are discussed for Federal policy of "gap-filling" initiatives at the State and Federal level to deal with the problem of the uninsured. Measures currently under active consideration that involve expansions of Medicaid and employment-related insurance are considered in the light of recent studies of the uninsured and recent simulations of their cost and coverage impacts. The limited impact of these gap-filling measures on additional national health spending, in contrast to program costs and Federal outlays, is emphasized. Placing greater emphasis on this broader societal perspective could assist Federal policymakers in developing an acceptable strategy for covering the uninsured.
