Medicare Savings Program Coverage of Part B Costs Explained
Last Updated: November 6, 2026
Quick Summary
A medicare savings program is a state-run assistance program that helps people with limited income and resources pay some of their Medicare costs, such as the Part B premium. You apply through your state Medicaid agency, and the amount it covers depends on which of the four programs you qualify for.
- There are four Medicare Savings Programs: QMB, SLMB, QI and QDWI.
- QMB pays your Part A and Part B premiums, deductibles and coinsurance, the most help available.
- SLMB and QI pay only the Part B premium, leaving deductibles and coinsurance on you.
- Eligibility depends on monthly income and countable resources, and limits differ by program and state.
- Confirm billing protections and renewal dates with your state Medicaid office after you are approved.

Medicare Savings Programs are one of the most useful ways for lower-income people to cut what they pay for Medicare, yet many eligible people never apply. This guide from Your Medicare Advantage Guy explains how a Medicare Savings Program coverage of Part B costs works, which costs it can pay, and how to check whether you might qualify. We cover the four programs, what each one pays, how eligibility is decided, and what to do after you apply. Our goal is to make the process simpler, so you can keep more of your money for food, housing and medicine.
What a Medicare Savings Program Is and Who Runs It
A Medicare Savings Program is a state-run assistance program that helps people with limited income and resources pay some of their Medicare costs (Medicare Savings Programs). It does not replace Medicare. Instead, it pays premiums, deductibles or coinsurance that you would otherwise owe on your own.
Each state runs its own programs under federal rules, so the exact limits and application steps can vary. You apply through your state Medicaid agency, not through Medicare itself. Medicare.gov and your state Medicaid office are the official places to confirm current details.
The Four Medicare Savings Programs and What Each One Pays
There are four Medicare Savings Programs. Each one covers a different set of costs, and eligibility rises or falls depending on your income. If you may also need help with drug costs, see our step-by-step Extra Help application guide.
- Qualified Medicare Beneficiary (QMB): The most help available. It pays your Part A and Part B premiums, deductibles and coinsurance.
- Specified Low-Income Medicare Beneficiary (SLMB): Pays your Part B premium only.
- Qualifying Individual (QI): Pays your Part B premium, with a limited number of slots and a first-come basis.
- Qualified Disabled and Working Individuals (QDWI): Pays your Part A premium for certain people with disabilities who went back to work.
If you only remember one thing, remember this: QMB covers the most costs, and the other three mainly cover the Part B premium.
Medicare Part B Premium Assistance Compared Side by Side
The Part B premium is the monthly amount deducted from Social Security for doctor visits, outpatient care, and most preventive services. The Part B premium is set by Medicare each year, and the Part B deductible and coinsurance also change over time. Confirm the current premium, deductible and coinsurance amounts at medicare.gov before you rely on them.
Here is how each Medicare Savings Program handles those Part B costs:
| Program | Part B Premium | Part B Deductible | Part B Coinsurance | What This Means in Practice |
|---|---|---|---|---|
| QMB | Paid in full | Paid | Paid | You should owe nothing for covered Part B services; providers cannot bill you for Medicare cost-sharing. |
| SLMB | Paid in full | Not paid | Not paid | Your premium deduction stops, but you still owe the deductible and 20% coinsurance. |
| QI | Paid in full | Not paid | Not paid | Same as SLMB, but slots are limited and filled on a first-come basis. |
| QDWI | Not applicable (Part A only) | Not paid | Not paid | Helps with the Part A premium for certain working people with disabilities; Part B cost-sharing is unchanged. |
Notice that only QMB helps with the deductible and coinsurance. The others stop at the premium. That difference matters a lot if you use the doctor often. A simple scenario shows why: suppose you have several specialist visits in a year. Under QMB, you should owe nothing for covered Part B cost-sharing. Under SLMB or QI, you would still owe the Part B deductible and coinsurance, which can add up quickly even though your premium is covered.
Part B Deductibles and Coinsurance Under QMB
Under QMB, a provider cannot bill you for the Part B deductible, coinsurance, or copayment for a covered service (Qualified Medicare Beneficiary (QMB) Program Group). That protection is not automatic in every billing system, so you may still receive a statement that shows a balance. If you get a bill you think is wrong, contact your state Medicaid office or Medicare right away. Keep copies of every statement you receive, note the date you called, and ask the provider's billing office to reprocess the claim with your QMB status on file.
For example, if a provider bills you for a covered service, the provider should bill Medicare, not you, for the cost-sharing that QMB covers. If the bill arrives anyway, call the provider and explain that you have QMB. Ask them to check your eligibility through the state Medicaid system before you pay anything. If they will not correct it, contact your state Medicaid agency and ask for help with the billing problem.
What Premium Assistance Does Not Cover
Even QMB does not pay for everything. It does not cover Part D prescription drug premiums, and it does not pay for services Medicare does not cover. If you have a Medicare Advantage plan, QMB still helps with Original Medicare cost-sharing, but check with your plan about how the state's payment is coordinated. If you have QMB and a Medicare Advantage plan, confirm with both the plan and the state Medicaid office that no cost-sharing is being charged in error.
Medicare Savings Program Eligibility: Income and Resource Limits
Eligibility depends on your monthly income and the value of your countable resources, such as bank accounts and certain investments. Your home and one car are usually not counted. Income limits are set as a percentage of the federal poverty level, and they change each year.
Two things to know:
- Income limits differ by program. QMB has the lowest income limit, and QI has the highest.
- Your state may use different rules. Some states use higher limits or ignore certain income.
Check your state's current limits through your Medicaid agency before you assume you do or do not qualify.
How to Apply for a Medicare Savings Program and Check Your Application
Applying is a straightforward process when you know what to expect. Follow these steps:
- Gather proof of income, such as Social Security award letters and recent pay stubs.
- Collect bank statements and any other proof of resources.
- Find your state Medicaid application, usually online or at a local benefits office.
- Complete the form and submit it with copies of your documents.
- Watch your mail for a decision letter, and respond quickly to any request for more information.
After you submit, call your state office if you have not heard back within the timeframe they list. A quick follow-up often prevents delays.
What Happens After Approval, Billing Protections and Renewals
Approval is not the end of the process. The state must transmit your eligibility to Medicare and, for premium-paying programs, arrange for the Part B premium to be paid. That handoff is where most delays and billing problems occur, so it helps to know what should happen and what to do when it does not.
How the State Payment Reaches Medicare
After your state Medicaid agency approves you, it sends your eligibility information to the appropriate federal systems. Your state Medicaid office can explain how it handles payment of the Part B premium for your program. Your Social Security statement should eventually show that the Part B premium is no longer being deducted, or that it is being refunded if a deduction was taken after your approval date.
Processing times vary by state. If your deduction continues beyond the timeframe your state lists, call your state Medicaid office first and ask whether your eligibility has been transmitted. Then contact Social Security to confirm what their records show. Keep a note of each call, the date, and the representative's name or reference number.
Watch out: if Social Security deducts a Part B premium for a month in which you were already approved for QMB, SLMB, or QI, you may be due a refund. Ask both the state and Social Security how the retroactive payment will be handled rather than assuming the deduction will correct itself.
Billing Protections Under QMB
QMB status comes with federal billing protections for covered Medicare services. Your state Medicaid office can explain how these protections apply to your situation. If you receive a bill that includes cost-sharing you believe QMB should cover, take these steps:
- Do not pay the disputed amount yet. Call the provider's billing office and tell them you have QMB.
- Ask them to verify your eligibility through the state Medicaid system and to reprocess the claim with the correct cost-sharing information.
- If the provider will not correct the bill, contact your state Medicaid agency and ask for help resolving the billing problem. Keep copies of the bill, your QMB approval letter, and notes from your calls.
- If the problem continues, contact your State Health Insurance Assistance Program (SHIP) for counseling, or contact Medicare to ask about filing a complaint.
Billing problems of this kind are often caused by outdated eligibility records, and a call from the state Medicaid office to the provider can help resolve them.
Renewals and Reporting Changes
Medicare Savings Programs typically require periodic renewal, and the renewal process can differ by state. Some states send a renewal packet automatically; others require you to contact the office. Missing a renewal can stop your benefits even if you still qualify, so mark the renewal date on your calendar as soon as you are approved. Our guide explains how to complete the renewal process step by step.
You also need to report changes that could affect eligibility, such as a raise, a new job, marriage, a move to another state, or a change in your countable resources. Report changes within the timeframe your state requires.
If you move to another state, your current coverage does not automatically transfer. You will need to apply in your new state and may face a gap in assistance while the new application is processed. Start the new application as soon as you have a new address.

Frequently Asked Questions
Does a Medicare Savings Program pay for Part B?
Some do. Medicare Savings Programs are run through state Medicaid agencies with federal rules, and depending on the program, they can pay all or part of the Medicare Part B monthly premium. The Qualified Medicare Beneficiary (QMB) program also covers Part B deductibles and coinsurance for Medicare-covered services. The Specified Low-Income Medicare Beneficiary (SLMB) and Qualifying Individual (QI) programs cover only the Part B premium. Check the current premium amount and program rules with your state Medicaid office or Medicare.gov, since figures change each year.
Which Medicare Savings Program pays the Part B premium?
All three programs that help with Part B premiums pay it: QMB, SLMB and QI. QMB pays the premium and also covers Part B cost-sharing. SLMB and QI pay only the premium, with QI offering a smaller benefit for people whose income is slightly higher. Qualified Disabled and Working Individuals (QDWI) is a fourth category that covers Part A premiums rather than Part B. Your state Medicaid agency decides which category you fit based on income and resources.
How do I apply for a Medicare Savings Program?
Apply through your state Medicaid agency, which handles Medicare Savings Program applications in most states. You can usually apply online, by mail or in person. Gather proof of income, bank and asset statements, your Medicare card and Social Security award letter before you start. Keep copies of everything you send. If you already receive Medicaid or Supplemental Security Income, you may be eligible automatically, so ask before submitting a separate application.
