Centers for Medicare and Medicaid Services

The Centers for Medicare and Medicaid Services (CMS) annually disseminates more data than any other federal agency or private-sector company to researchers, policy groups, associations, medical groups, and private citizens. It administers the Medicare program and works in partnership with states to administer Medicaid, the State Children's Health Insurance Program and health insurance portability standards.

The Teradata environment at CMS comprises the largest volume of healthcare-related data files in the world. A Teradata Professional Services team assists CMS in establishing, supporting, and governing the data warehouse, while a separate Teradata Customer Services group provides business-critical maintenance, customer education, installation, and other services. The data warehouse is expected to grow to 180 terabytes in four years. The centralization of data will improve the ability to analyze data for many purposes, notably, to identify fraud in claims.
