Disclosure protections have been applied to the file, including de-identification and other methods; as a result, the MCBS PUF does not require a Data Use Agreement. These data are intended to support research on the Medicare program. Link to the site to access these data and for more information on:

The Limited Data Set Files (LDS) contain beneficiary level health information (excluding any direct identifiers, as outlined in the Health Insurance Portability and Accountability Act (HIPAA Privacy Rule)).
