Effect of Cost-Sharing Reductions on Preventive Service Use Among Medicare Fee-for-Service Beneficiaries

Abstract

Elimination of cost sharing may be an effective strategy for increasing preventive service use, but the impact could depend on the characteristics of the procedure, its cost, and the disease and populations it targets. These historical findings suggest that, with implementation of Section 4104, the greatest increases in utilization will be seen for preventive services that screen for diseases with high incidence or prevalence rates that increase with age, that are expensive, and that are performed on a frequent basis.
