Extra Help: Medicare's Low-Income Prescription Drug Subsidy
Extra Help (formally the Part D Low-Income Subsidy, or LIS) is a federal program that pays some or all of your Part D premium, deductible, and drug copays, depending on your income and resources. It's one of the most underused benefits in Medicare — the Social Security Administration has repeatedly found that a meaningful share of people who qualify never apply, often because they assume a program this generous must not apply to them.
Two ways to qualify
Automatic ("deemed") eligibility — you don't need to apply at all if you already:
- Have both Medicare and full Medicaid coverage,
- Receive Supplemental Security Income (SSI), or
- Are enrolled in a Medicare Savings Program (MSP) through your state, which helps pay Part B premiums.
If any of those apply, you're generally enrolled in Extra Help automatically, at the full-subsidy level. You'll get a letter confirming it — but if you're not sure, it's worth confirming rather than assuming.
Application-based eligibility — if none of the above applies, you can still qualify based on your income and resources (savings, investments, and similar assets — your home and car generally don't count). The exact income and resource limits are set federally and adjust most years, so don't rely on a number you saw a year or two ago — check the current limits directly at ssa.gov/extrahelp or by calling Social Security. Depending on where your income and resources fall, you may qualify for the full subsidy (lowest possible costs — often no deductible and small fixed copays) or a partial subsidy (a sliding scale of reduced costs).
How to apply
Apply through the Social Security Administration — online, by phone, by mail, or in person at a local office — or through your state's Medicaid office. There's no single enrollment window for Extra Help; you can apply any time of year, and if you're approved, you typically get a Special Enrollment Period to switch into a Part D or MA-PD plan without waiting for the next Open Enrollment period.
What it actually saves
For someone on the full subsidy, the practical effect is often: no Part D premium (as long as you pick a plan priced at or below the regional benchmark), no annual deductible, and copays reduced to small fixed amounts per prescription instead of percentage-based coinsurance. Combined with the annual out-of-pocket cap that now applies to everyone, Extra Help recipients often reach very low total annual drug costs.
Don't assume — check
Income and resource thresholds shift, your own situation changes, and the program is genuinely there for people who work part-time, live on a modest pension, or have modest savings — not just those with zero income. If you've never checked and your income is limited, a five-minute application is worth the possible savings.
