Center for Medicare & Medicaid Services (CMS) , Medicare Claims data

2016–2021. CMS compiles claims data for Medicare and Medicaid patients across a variety of categories and years. This includes Inpatient and Outpatient claims, Master Beneficiary Summary Files, and many other files. Indicators from this data source have been computed by personnel in CDC's Division for Heart Disease and Stroke Prevention (DHDSP). This was one of the datasets provided by the National Cardiovascular Disease Surveillance System and presented on DHDSP’s Data, Trends, and Maps online tool. This tool was retired in April of 2024 and this dataset will not be updated. Contact dhdsprequests@cdc.gov if you need assistance with data previously included in this dataset. The data are organized by location (national and state) and indicator. The data can be plotted as trends and stratified by sex and race/ethnicity.
