There are four types of Medicare Savings Programs (MSPs): Qualified Medicare Beneficiary (QMB), Specified Low-Income Medicare Beneficiary (SLMB), Qualifying Individual (QI), and Qualified Disabled & Working Individual (QDWI). Each one targets a different income level and covers a different slice of your Medicare costs. According to Medicare.gov, your state determines which program you qualify for when you apply.
Here is what each program covers at a glance:
- QMB pays Part A premiums (if you owe them), Part B premiums, and Part B deductibles, coinsurance, and copays.
- SLMB pays your Part B premium only; you must have both Part A and Part B.
- QI also pays your Part B premium only; you must have both Part A and Part B.
- QDWI pays your Part A premium only, for a narrow group of disabled working people who lost premium-free Part A after returning to work.
Your next step is simple: contact your state Medicaid or Medical Assistance office and apply. Apply even if you are not sure you qualify. State rules are the final word, and they sometimes count income and resources more generously than federal charts suggest.
Pro Tip: Apply for an MSP and Extra Help for Part D at the same time. Social Security will automatically forward your Extra Help application to your state to start an MSP application unless you ask them not to.

What do the four types of Medicare savings programs actually cover?
Each MSP has a distinct benefit level, and understanding the differences helps you figure out which one fits your situation.
Qualified Medicare Beneficiary (QMB)
QMB is the most comprehensive of the four. It covers Part A premiums when you owe them, Part B premiums, and all Part B cost-sharing, including deductibles, coinsurance, and copays for covered Medicare services. If you are enrolled in QMB, providers cannot bill you for Medicare-covered services beyond what Medicare and Medicaid pay. QMB typically serves beneficiaries with the lowest incomes among the four programs.
Example: A retired single adult on a fixed Social Security income who owes a Part B premium of $185 per month and faces regular specialist copays could have all of those costs eliminated through QMB.
Specified Low-Income Medicare Beneficiary (SLMB)
SLMB covers your Part B premium only. You must have both Part A and Part B to qualify. It does not pay deductibles or copays, but eliminating the monthly Part B premium still frees up real money each year. SLMB fits people whose incomes are slightly above QMB limits but still modest.
Qualifying Individual (QI)
QI also pays your Part B premium, and you must have both Part A and Part B. The key difference from SLMB: QI funding is capped each year, and in many states it is handled on a first-come, first-served basis. Applying early in the year matters. QI is for people with incomes a step above SLMB limits.
Qualified Disabled & Working Individual (QDWI)
QDWI is narrow in scope. It pays Part A premiums only, and only for working disabled people under 65 who lost premium-free Part A after returning to work and who are not receiving state Medicaid assistance. It does not cover Part B costs at all. The income limits for QDWI are notably higher than the other three programs, reflecting its different target group.
Pro Tip: When you are approved for an MSP, treat it as a two-step process. MSP approval for QMB, SLMB, or QI automatically triggers Extra Help eligibility for Part D. Gather your Medicare drug plan information alongside your MSP paperwork so you can coordinate enrollment without a gap in prescription coverage.
Side-by-side comparison of all four MSPs
| Feature | QMB | SLMB | QI | QDWI |
|---|---|---|---|---|
| Costs covered | Part A premium, Part B premium, deductibles, coinsurance, copays | Part B premium only | Part B premium only | Part A premium only |
| Who it fits | Lowest-income Medicare beneficiaries | Slightly higher income than QMB | Income above SLMB; first-come, first-served in many states | Disabled, working individuals under 65 who lost premium-free Part A |
| Part A + Part B required? | Part B required; Part A if you owe a premium | Yes, both | Yes, both | Part A (owed as premium); not Part B |
| Federal baseline income limit (individual/couple) | $1,350 / $1,824 per month | $1,616 / $2,184 per month | $1,816 / $2,455 per month | $5,405 / $7,299 per month |
| Automatic Extra Help for Part D? | Yes | Yes | Yes | No |
| Where to apply | State Medicaid/Medical Assistance office | State Medicaid/Medical Assistance office | State Medicaid/Medical Assistance office | State Medicaid/Medical Assistance office |
Federal income limits come from Medicare’s Getting Started publication and increase each year. Alaska and Hawaii have higher limits. Your state may also count income and resources differently, so these figures are a starting point, not a ceiling.
How MSPs connect to Part D, Medicaid, and other benefits
Qualifying for QMB, SLMB, or QI automatically qualifies you for Extra Help with Medicare Part D prescription drug costs. Extra Help covers Part D premiums, deductibles, coinsurance, and other out-of-pocket drug costs. That is a significant benefit on top of whatever premium savings your MSP provides.
A few practical points to keep in mind:
- MSP approval is not the same as full Medicaid. An MSP is a subset of Medicaid benefits focused on Medicare cost-sharing. Full Medicaid covers a broader range of services, and whether you qualify for both depends on your state’s income and asset rules.
- QMB and drug costs: If you have both QMB and full Medicaid, you pay no more than $4.90 per covered drug under Part D Extra Help.
- After MSP approval, review your Part D plan. Extra Help may change which plan is best for you. You gain a Special Enrollment Period to switch plans after qualifying.
- QDWI does not trigger Extra Help. Only QMB, SLMB, and QI carry that automatic link.
Pro Tip: You can apply for Extra Help and an MSP at the same time through Social Security. This single application can set both benefits in motion and reduce the paperwork you need to manage.
Why state rules matter more than the federal chart
MSPs are federally funded but state-administered. Your state Medicaid or Medical Assistance office runs the program, processes your application, and decides which MSP you qualify for based on its own counting rules.
Key points about state variation:
- Some states exclude certain types of income (such as irregular earnings or specific benefit payments) when calculating eligibility.
- States may also count fewer resources than the federal baseline, meaning you could qualify even if you think your savings are too high.
- Alaska and Hawaii have higher income and resource limits than the contiguous 48 states.
- MSPs are generally not available in U.S. territories.
- Program names can differ slightly by state, though the four federal categories remain the same.
To find your state’s specific limits and contact information, visit Medicare.gov’s cost help page or search for your state Medicaid office directly. Calling your state office is often the fastest way to get current limits and confirm what documents you need. For seniors managing multiple household expenses, pairing MSP savings with broader money tips for seniors can stretch a fixed income further.
How to apply for Medicare savings programs: a step-by-step checklist
Applying is straightforward. Here is what to do:
- Gather your documents. Collect proof of income (Social Security award letter, pay stubs, pension statements), recent bank statements, your Medicare card, and proof of any other resources such as savings accounts or investments.
- Contact your state Medicaid or Medical Assistance office. This is where you apply. You can find your state’s office through Medicare.gov or by calling 1-800-MEDICARE (1-800-633-4227).
- Submit your application. Many states offer paper forms, online applications, and in-person options. For QI, apply as early in the year as possible given the first-come, first-served funding.
- Coordinate with Part D. If you are applying for QMB, SLMB, or QI, ask about Extra Help at the same time. Social Security can initiate the MSP referral when you apply for Extra Help.
- Follow up on your application. Processing times vary by state. Ask your state office about retroactive coverage, which can sometimes apply to months before your approval date.
Pro Tip: Apply even if you think your income or assets are too high. State rules often count resources differently than federal charts imply, and Medicare.gov explicitly recommends applying to let your state make the final determination.
What to do if your MSP application is denied
A denial is not the end of the road. You have the right to appeal, and free help is available.
- Request a written denial notice immediately. It will state the reason for denial and the deadline to file an appeal, which is typically 90 days from the notice date.
- File a state administrative appeal or request a fair hearing. The process varies by state but generally involves a review of your case by a state hearing officer.
- Common reasons for denial include missing documentation, income reported incorrectly, or resources counted in a way that exceeds limits. Fixing these errors often resolves the issue.

| QMB offers the broadest coverage | QMB pays Part A premiums, Part B premiums, and all Part B cost-sharing including deductibles and copays. |
| Extra Help link for Part D | Qualifying for QMB, SLMB, or QI automatically qualifies you for Extra Help with Part D drug costs. |
| State rules are the final word | Income and resource limits vary by state; Alaska and Hawaii have higher limits than the federal baseline. |
| Apply even if unsure | Your state Medicaid office makes the final eligibility determination, and state rules are often more generous than federal charts suggest. |
Why MSPs deserve a place in your retirement budget
Most conversations about retirement planning focus on investment returns and withdrawal rates. Healthcare costs rarely get the same attention, even though they are often the largest variable expense in a fixed-income budget. That gap is where MSPs do their most important work.
Eliminating a monthly Part B premium, removing copay exposure, and unlocking Extra Help for prescriptions can collectively free up hundreds of dollars a month. For someone on Social Security, that is not a minor adjustment. It is the difference between a budget that works and one that slowly erodes savings. Readers thinking about how to protect retirement assets while managing healthcare costs will find Savings Grove’s retirement budget adjustment strategies a useful companion to MSP planning.
The other underappreciated point: MSPs are not just for people in financial crisis. The income limits, especially for QI and QDWI, reach higher than most people expect. Many beneficiaries who assume they earn too much to qualify are wrong. The only way to know for certain is to apply.
