title: The Impact of Medicare Part D on Emergency Department Visits.
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.
