Medicare program; Medicare Part D claims data. Final rule.

This final rule allows the Secretary to collect claims data that are presently being collected for Part D payment purposes for other research, analysis, reporting, and public health functions. The Secretary needs to use these data because other publicly available data are not, in and of themselves, sufficient for the studies and operations that the Secretary needs to undertake as part of the Department of Health and Human Service's obligation to oversee the Medicare program, protect the public's health, and respond to Congressional mandates. These data will also be used to better identify, evaluate and measure the effects of the Medicare Modernization Act of 2003, (MMA).
