The Medicare Part D Low-Income Subsidy (LIS/Extra Help) is one of several core benefits programs for low-income Medicare beneficiaries. LIS helps those with limited means to afford their prescriptions.

Yet many people with Medicare remain unaware of and unenrolled in LIS. This mapping tool enables benefits counselors to find information on these individuals potentially eligible for but not enrolled in LIS down to the county level.

How to use this graphic

Counties colored blue are those areas likely to have unmet need for enrollment in LIS/Extra Help. The darker the shade of blue, the larger the percentage of Medicare beneficiaries in the county who are estimated to be eligible but not enrolled in the subsidy.

Counties shaded gray are unlikely to have a high degree of unmet need. That’s not to say there’s no one who’s eligible but not enrolled in these localities, especially with 10,000 people a day in the United States aging into Medicare and needing help getting into benefits for which they may qualify – and, as noted below in the data sources, these are underestimates.

Mousing over a bubble or county will provide more information about the corresponding area. Zoom controls for the map will appear in the upper left when you mouse over the map. In addition, you may pan the map by holding both mouse buttons and dragging.
