This dataset contains the number of beneficiaries of the different types of Medicare Part D Plan with prescription drug coverage. The data contains the number of Medicare beneficiaries (patients) with creditable prescription drug coverage by type of Medicare Part D plan. The data is displayed by state.


The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) added prescription drug coverage to Medicare (Medicare Part D), beginning on January 1, 2006.
