Medicare Savings Program vs. Medicaid: What's the Real Difference

No, they are not the same, but they often work together

A Medicare Savings Program (MSP) is a Medicaid program run by your state that helps pay some of your Medicare costs — premiums, deductibles, and copayments. Medicaid itself is a separate program that covers medical services for people with low income. The key difference: MSP helps you use Medicare better by covering what Medicare doesn't pay. Medicaid covers services that Medicare doesn't cover at all, like long-term care or dental work.

You can have both at the same time. In fact, if you may have access to for an MSP, you almost always may have access to for Medicaid too. When you have both, Medicaid becomes your "secondary payer" — it covers costs that Medicare leaves behind. This combination is sometimes called "dual may be able to access" status, and it can cut your out-of-pocket costs significantly.

Key Takeaways

Medicare Savings Programs are state-run Medicaid programs that pay your Medicare premiums and cost-sharing, not a separate federal program.
Medicaid covers medical services and long-term care that Medicare does not, while MSP only helps with Medicare's own costs.
You can be enrolled in both MSP and Medicaid at the same time, and most people who may have access to for MSP also may have access to for Medicaid.
Income limits for MSP vary by state but are generally between 120% and 200% of the federal poverty level.
Your state Medicaid office determines which MSP category you fit into based on your income and assets.

How Medicare Savings Program works as a Medicaid benefit

When you enroll in an MSP, your state's Medicaid program pays certain Medicare costs on your behalf. There are four MSP categories, each covering different combinations of Medicare premiums and cost-sharing. The category you enter depends on your income level and state rules.

The most common is the may have access to Medicare Beneficiary (QMB) program, which covers your Part B premium, deductible, and copayments. If your income is slightly higher, you might fit into the Specified Low-Income Medicare Beneficiary (SLMB) program, which covers only your Part B premium. Two other categories — may have access to Individual (QI) and may have access to Disabled and Working Individual (QDWI) — cover Part B premiums for people in specific situations.

MSP does not cover your actual medical care. It only pays the costs that Medicare itself charges you. If Medicare covers a doctor visit, MSP can pay your copay. If Medicare does not cover a service at all — like dental cleaning or hearing aids — MSP cannot help with that cost.

What Medicaid covers that Medicare does not

Medicaid is a broader program that covers services Medicare leaves out entirely. Long-term care in a nursing home or assisted living is the biggest one. Medicare covers only short-term skilled nursing care after a hospital stay; Medicaid covers extended stays when you need custodial care. Medicaid also covers dental services, vision care, hearing aids, and transportation to medical appointments — services Medicare rarely covers.

Each state's Medicaid program decides which services to cover beyond the federal minimum, so what you get in one state may differ from another. Some states cover more mental health services, prescription drugs, or therapy than others. When you have both MSP and Medicaid, you use Medicare first for services it covers, then Medicaid picks up gaps or covers services Medicare does not.

Income and asset limits differ between the two programs

MSP has income limits that vary by state but generally fall between 120% and 200% of the federal poverty level. For 2024, that means roughly $1,500 to $2,500 per month for a single person, depending on your state and which MSP category you enter. Asset limits also vary — some states have no asset limit for MSP, while others cap assets at $7,500 or $15,000.

Medicaid income and asset limits are set by each state and are often higher than MSP limits. Some states use "medically needy" rules that let you may have access to for Medicaid if your medical bills are high enough, even if your income is above the limit. Because MSP is technically a Medicaid program, your state Medicaid office handles both applications together.

The exact numbers change yearly and depend on where you live. Your state Medicaid office or a local Area Agency on Aging can tell you the current limits for your situation.

How to learn about you may have access to for both programs

Start by contacting your state Medicaid office or your local Area Agency on Aging. You can also call 1-800-MEDICARE to ask for a referral to your state's MSP program. Many states have a single process for both MSP and Medicaid, so you do not need to explore separately.

When you explore, bring proof of income (recent pay stubs, Social Security statements, or tax returns), proof of citizenship or immigration status, and a list of your assets. The process usually takes two to four weeks. If you are already on Medicare, you can explore for MSP at any time — there is no enrollment period.

Some people are automatically referred to MSP when they turn 65 and enroll in Medicare, especially if they received Supplemental Security Income (SSI). Others have to explore on their own. Your Social Security office can tell you whether you were referred.

What happens when you have both MSP and Medicaid

When you have both, Medicare is your primary insurance and Medicaid is secondary. Here is how it works in practice: you go to a doctor who accepts Medicare. Medicare processes the claim and pays its share. Then the claim automatically goes to Medicaid, which pays the copay or deductible that Medicare left behind. You typically pay nothing out of pocket.

Providers must accept both Medicare and Medicaid to treat you under this arrangement. Most do, but some do not accept Medicaid. Before you schedule an appointment, confirm that the provider accepts both programs. If a provider accepts only Medicare, you will owe the copay yourself.

Having both programs also protects you if you need services Medicaid covers but Medicare does not. For example, if you need long-term nursing home care, Medicare will not pay, but Medicaid will — as long as you meet the income and asset limits at that time.

MSP does not replace Medicaid, and Medicaid does not replace MSP

Some people think MSP is a "lite" version of Medicaid or that getting MSP means they do not need Medicaid. That is not how it works. MSP is specifically designed to help Medicare beneficiaries afford Medicare costs. Medicaid is a separate safety net for medical and long-term care services.

If you may have access to for MSP, your state will usually enroll you in Medicaid too, unless you decline. Declining Medicaid to keep only MSP is rarely a good idea, because you lose coverage for services like nursing home care, dental work, and other gaps. The two programs complement each other.

If you are unsure whether you have both, call your state Medicaid office and ask. They can tell you what programs you are enrolled in and what each one covers.

Frequently Asked Questions

Can I have Medicare Savings Program without Medicaid?

Technically yes, but most states automatically enroll you in both if you may have access to for MSP. You can decline Medicaid if you choose, but you would lose coverage for services like nursing home care and dental work. Most people keep both because the combination covers far more than MSP alone.

Do I have to pay a premium for Medicare Savings Program?

No. MSP itself has no premium — it is a Medicaid benefit your state pays for. However, you still pay the Medicare Part D premium (for prescription drug coverage) unless you also may have access to for Extra Help, a separate program. Your state Medicaid office can tell you if you may have access to for Extra Help.

What if my income goes above the MSP limit?

Your state will disenroll you from MSP, usually with 30 days' notice. You will still have Medicare and will owe your full Part B premium again. If your income stays above the MSP limit but below your state's Medicaid limit, you may stay on Medicaid for other services. Contact your state Medicaid office to understand what happens next.

Does MSP cover prescription drugs?

No. MSP covers Medicare premiums and cost-sharing only. Prescription drug coverage comes through Medicare Part D, which you enroll in separately. If you have low income, you may may have access to for Extra Help to pay Part D premiums and copayments — that is a different program from MSP.

How do I know which MSP category I am in?

Your state Medicaid office assigns you to a category based on your income. You do not choose. The category determines which Medicare costs your state will pay. Your Medicaid notice of approval will tell you which category you are in and what it covers.
