Vaccination Mapping Tool:  Live-Tracking Influenza Vaccination Claims of Medicare Beneficiaries

The National Vaccine Program Office (NVPO), in partnership with the Center for Medicare and Medicaid Services (CMS), created this mapping tool as a resource for researchers, providers, and health care workers to track influenza (flu) vaccination claims rates of Medicare beneficiaries in real-time.* The new tool includes information for every community in the United States.

By clicking on any state or searching for a specific location, the tool generates the number of Medicare beneficiaries living in a specific area and indicates the flu vaccination claims rates.** The tool also retrieves flu vaccination claims data for specific racial or ethnic populations within a state or community and shows if there are differences by race in the flu vaccination claims rate. Finally, data for disabled Americans under age 65 and covered by Medicare Fee-for-Service can also be seen.  

The mapping tool shows claims data only for those 65 and older and covered by Medicare Fee-for-Service. This includes more than two-thirds of Americans aged 65 and over as well as disabled Americans under age 65, but this information may not be representative of other groups. This tool should be used to compare relative vaccination rates between different locations, populations and different weeks, months and years. Some flu vaccines given may not be recorded in the claims database due to administration at alternative sites or lags in claims submission and, as a result, the vaccination rates shown here may be an underrepresentation of actual coverage rates.

* Claims are defined as requests for reimbursement submitted to CMS by health care providers.

** The claims rate is the number of flu vaccine claims relative to the number of beneficiaries.
