Abstract

The Medicare Part D program introduced prescription drug coverage for seniors in 2006. We examine the impact of this program on the use of emergency department (ED) care. Using a difference‐in‐differences model, we find declines in the number of ED visits for non‐emergency care but not for emergency care, suggesting that Part D may have led to better management of health and reduced unnecessary use of EDs.
