These administrative data from the Centers for Medicare and Medicaid Services (CMS) contain acute care claims and post-acute care claims and assessment data for 100% of Medicare fee-for-service beneficiaries for CY2018-2021.
These are beneficiary-level, research-identifiable files which require protection and security as per Data Use Agreement requirements with CMS to prevent access to these data by anyone outside of the study team members granted access by the Data Use Agreement.

These data enable examination of access to post-acute care following acute hospitalization, service delivery within skilled nursing facilities and home health agencies, and outcomes of post-acute care. These rich data sources may be of value to other researchers interested in studies related to hospital, skilled nursing facility, and/or home health agency services for Medicare fee-for-service beneficiaries, including specific populations by geographic factors, sociodemographic characteristics, clinical characteristics/diagnoses, and more.
Data dictionaries, technical guidance and user manuals are available on the CCW website at https://www.ccwdata.org/web/guest/analytic-guidance.
