Medicare prescription drug benefit progress report: Findings from a 2006 national survey of seniors

A national survey in 2006 found that Part D secured drug coverage for most seniors who were without it in 2005, prior to the Medicare drug benefit. Seniors without drug coverage in 2006 generally fell into two groups: those in relatively good health and those potentially difficult to reach. Compared with seniors covered through employer plans or the Department of Veterans Affairs, Part D enrollees had higher out-of-pocket spending and greater cost-related nonadherence. Low-income subsidies offered protection against high out-of-pocket spending; without them, one-third of Part D enrollees at or below 150 percent of poverty paid more than $100 a month for their medications.
