Extra Help, Low Income Subsidy (LIS), program.

Extra Help, or LIS, is a government program that helps cover prescription drug costs for certain eligible Medicare beneficiaries with limited incomes, including monthly premiums, annual deductibles, and prescription co-payments. The amount of subsidy depends on your income compared to the Federal Poverty Level and resource limitations set by the Social Security Act.
