Prescription costs are one of the most unpredictable expenses seniors face — especially if you’re managing more than one chronic condition. Extra Help, officially the Low-Income Subsidy (LIS), is built specifically to bring that cost down.
Here’s how it works, who qualifies, and how to apply.
At a Glance
- What it is: A federal program that lowers Medicare Part D costs
- Who runs it: Social Security (applications) and CMS (Medicare oversight)
- What it can reduce: Premiums, deductibles, and copays
- Two levels: Full Extra Help (biggest savings) and partial Extra Help
- How to apply: Anytime during the year, not just during open enrollment
What Is Extra Help?
Extra Help lowers what you pay out of pocket for Medicare Part D (prescription drug coverage) if you have limited income and resources. It can:
- Lower or eliminate your monthly premium
- Reduce or eliminate your annual deductible
- Cap or reduce what you pay per prescription at the pharmacy
There are two tiers:
- Full Extra Help — for the lowest income and resource levels. Often brings premiums and deductibles to $0, with copays capped at a modest, set amount per prescription.
- Partial Extra Help — for those just above the full-benefit thresholds. Still reduces your premium and deductible, but uses a sliding-scale coinsurance rate instead of flat copays.
Who Qualifies?
Eligibility comes down to income and resources (assets), and both thresholds are updated annually. Because the exact numbers shift every year — and vary slightly by marital status — always check the current limits directly with Social Security rather than relying on a fixed figure.
As a general guide, this program targets Medicare beneficiaries with income around 150% of the federal poverty level or below, plus limited savings and investments. Your primary home, one vehicle, and certain other assets typically don’t count toward the resource limit.
Some people qualify automatically, with no application needed:
- Anyone enrolled in both Medicare and full Medicaid
- Anyone receiving Supplemental Security Income (SSI)
- Anyone enrolled in a Medicare Savings Program through their state
Everyone else who thinks they might qualify based on income and resources can apply directly.
What It Covers — and What It Doesn’t
Extra Help applies specifically to Medicare Part D. It reduces:
- Your monthly premium
- Your annual deductible
- Your copays or coinsurance
It does not cover Medicare Part B premiums (medical insurance). But if your income and resources are limited, you may separately qualify for a Medicare Savings Program, which helps with Part B costs. These are related but separate programs — a lot of people who qualify for one qualify for the other, so it’s worth checking both.
Why Your Plan Choice Matters
Getting approved for Extra Help is only half the equation. Which Part D plan you’re enrolled in also matters.
- Extra Help recipients often get access to a special enrollment period, letting them switch Part D plans outside the normal annual window in certain situations.
- CMS designates some plans in each region as “benchmark plans” — meaning their premium is fully covered for full Extra Help recipients. Pick a non-benchmark plan, and you might still pay part of the premium out of pocket, even with the subsidy.
A State Health Insurance Assistance Program (SHIP) counselor — a free service in every state — can help you pick a plan that actually maximizes your subsidy.
How to Apply
- Online — through the Social Security Administration’s website
- By phone — call Social Security to request an application or complete one over the phone
- By mail — request a paper application
- In person — at your local Social Security office
You’ll need to provide information on income, resources (bank accounts, investments, etc.), and household size. Social Security reviews the application and sends a decision letter. If approved, the subsidy gets applied to your Part D plan automatically.
One thing worth knowing: you can apply anytime during the year. Extra Help isn’t tied to Medicare’s annual Open Enrollment Period.
If Your Situation Changes
Since eligibility is based on your current income and resources, you’re generally required to report changes — say, drawing more heavily from savings or receiving an inheritance.
Social Security also periodically re-checks eligibility for many recipients. If you get a redetermination request, respond promptly — missing it can mean losing the subsidy.
How It Fits Into Your Bigger Medicare Picture
For seniors juggling multiple prescriptions, Extra Help can genuinely change which Part D or Medicare Advantage plan makes the most financial sense. It’s often discussed alongside:
- Medicare Savings Programs, which help with Part B premiums and cost-sharing
- State pharmaceutical assistance programs, which some states run independently to further cut drug costs
Because Extra Help interacts directly with your plan choice, it’s worth reviewing your Part D or Medicare Advantage plan annually with a SHIP counselor once you’re approved — just to make sure you’re getting the full benefit.
Frequently Asked Questions
Do I need to reapply every year? Not necessarily. Many recipients are automatically re-evaluated. But if your income or resources change significantly, or you get a redetermination request, respond promptly to avoid losing the subsidy.
Can I get Extra Help with a Medicare Advantage plan? Yes — as long as the plan includes prescription drug coverage (an MA-PD plan). Extra Help applies to the drug coverage portion.
What if I’m denied? You can request a reconsideration or appeal. It’s also worth checking eligibility for a state Medicare Savings Program, since the income and resource limits sometimes differ slightly.
Does it affect my Social Security retirement or SSI? No. Applying for or receiving Extra Help doesn’t reduce those benefits.
The Bottom Line
Extra Help can meaningfully lower what you pay for prescription drugs — but the exact savings depend on your income, resources, and which Part D or Medicare Advantage plan you choose. If there’s any chance you qualify, it’s worth applying directly through Social Security, and reviewing your plan choice with a free SHIP counselor once you’re approved.
