Medicare Electricity-Dependent Populations by Geography

Over 2.7 million Medicare beneficiaries rely on electricity-dependent durable medical and assistive equipment and devices, such as ventilators, to live independently in their homes. Severe weather and other emergencies, especially those with prolonged power outages, can be life-threatening for these individuals. The HHS emPOWER Map is updated monthly and displays the total number of at-risk electricity-dependent Medicare beneficiaries in a geographic area (i.e., state, territory, county, or ZIP Code), as well as near real-time natural hazard data.

Map users can select different geographies, as needed, to identify at-risk populations and download selected data results to inform emergency preparedness, response, recovery, and mitigation public health activities. Users can also access near real-time natural hazard data layers to anticipate and address the needs of at-risk community members in emergencies. For more information, review the job aids in the top right corner.

Medicare Electricity-Dependent Populations by Geography

This interactive table allows users to perform Medicare beneficiary data queries to identify unique data totals for multiple geographies that can also cross jurisdictional boundaries, including states/territories, counties, and ZIP Codes. Users can select different geographies, as needed, to identify individual and aggregated data totals for the selections and also download the selected data results for additional analysis. For more information on this query capability, review the HHS emPOWER Map Job Aid in the top right hand corner.

Details on Medicare Data
The map uses de-identified claims data, updated monthly, on Medicare Fee-for-Service and Medicare Advantage (Parts A, B and C) beneficiaries, which includes Americans age 65 and over, and disabled Americans under age 65. The totals listed here may underestimate the total at-risk Medicare beneficiary population due to certain Medicare policies and processes.

The "electricity-dependent" number, by location, represents the total number of beneficiaries with claims in Centers for Medicare and Medicaid Services (CMS) databases from the prior month for: ventilator, BiPAP, enteral feeding machine, intravenous (IV) infusion pump, suction pump, at-home dialysis machine, electric wheelchair, electric scooter, and electric bed equipment in the past 13 months; oxygen concentrator equipment in the past 36 months; and implanted cardiac devices that include left ventricular assistive device (LVAD), right ventricular assistive device (RVAD), bi-ventricular assistive device (BIVAD), and total artificial heart (TAH) in the past 5 years. To protect individual privacy, the following de-identification methodologies have been implemented: removal of all personal identifiers; aggregating data totals at the geographic level; and replacing any small cell size between 1 and 10 (e.g., a ZIP Code with only 3 individuals ) with an 11. Some ZIP Codes may not be represented on the map because they do not have geographical boundaries (e.g. post office boxes, a large building, etc.). In these instances, we add their total to the geographical ZIP Code where the post office box or building can be found.

Intended Use and Contact Information

To protect the privacy of Medicare beneficiaries, the HHS emPOWER Program uses several de-identification methods to minimize, if not eliminate, the possibility that someone could identify individuals. Methodologies used are in accordance with the Health Insurance Portability and Accountability Act (HIPAA) of 1996, Privacy Act of 1975 and the U.S. Department of Health and Human Services Centers for Medicare & Medicaid Services Cell Size Suppression Policy, which dictates that no cell with a value of 1 to 10 be reported or derived from other reported cells or information. More information is available at Send an email to To address this requirement, small cell values between 1 and 11 are reported as 11.
