Database Description

The UNC Department of Epidemiology houses a sample of approximately 20 percent of all Medicare beneficiaries age 65 years and older with fee-for-service coverage of Medicare Parts A, B, and D. Beneficiaries are included in the data set if they have simultaneous coverage of Parts A, B, and D for at least one calendar month in 2007-2014. Once a beneficiary meets these selection criteria, all available fee-for-service claims data and death data are included from that point through the end of 2014. The data are updated yearly using the same sampling scheme for each year. There is an approximately 24 month lag for updating (e.g., the 2011 data were uploaded in December 2013).
