This article, published in Health Care Financing Review, explores the rising expenditures on prescription drugs and discusses changes to Medicaid and Medicare as a result of the Medicare Prescription Drug Improvement and Modernization Act of 2003 with special attention to “Part D”.  The article notes that prescription drug costs for dually eligible beneficiaries will shift from Medicaid to Medicare thereby relieving some of the economic burden those drugs placed on states and considers other implications of the legislation.
