Dual Eligibles' Transition: Part D Formularies' Inclusion of Commonly Used Drugs (PDF; 1.14 MB)
"This study determined the extent to which Medicare prescription drug plan (PDP) formularies include the drugs that the dual eligible population (i.e., beneficiaries of both Medicare and Medicaid) commonly used under Medicaid. On January 1, 2006, outpatient prescription drug coverage for dual eligibles was transferred from Medicaid to Medicare. Differences in coverage of commonly used drugs may present challenges during this transition. We identified 200 drugs highly utilized by the dual eligible population in 2005. Of these, 178 drugs are eligible for Part D coverage, and 22 fall into categories that are statutorily excluded from Part D, but which States may opt to cover through their Medicaid programs."
