The Medicare prescription drug benefit, introduced in January 2006, has had a substantial impact on the lives of adults disabled by mental illness. However, few studies have undertaken an exploration of the difference that this benefit has made to beneficiaries' access to medication. This study uses a qualitative approach to examine beneficiaries' experiences with the Medicare Part D benefit, and whether having Medicare prescription drug coverage is perceived as helpful. Twenty-six Medicare beneficiaries with mental illness were interviewed regarding their opinions of the Part D benefit, and the investigator found that most beneficiaries were highly satisfied with their prescription drug coverage. However, they would appreciate more information from the Medicare program about their benefits. In addition, beneficiaries were concerned about the possibility of increased future costs. Overall, however, these participants in the Medicare Part D program who had mental illness felt that their needs for psychotropic and other medications were met.
