Medicare Savings Programs and Medicaid: How They Work Together and Apart

The core difference: Medicare is federal insurance you've earned, Medicaid is state assistance based on income

Medicare is a federal health insurance program you become may be able to access for at 65 (or earlier if you have certain disabilities or end-stage renal disease). You pay into it through payroll taxes during your working years, and it covers hospital care, doctor visits, and prescription drugs. You get it regardless of your income or assets.

Medicaid is a joint federal-state program that covers low-income people of any age. Each state sets its own income limits and decides what services to cover, so what Medicaid pays for in one state may differ from another. You don't pay into Medicaid through taxes — it's funded by general tax revenue and is means-tested, meaning your income and assets matter.

A Medicare Savings Program is a Medicaid program that helps people who have Medicare but can't afford Medicare's premiums, deductibles, and copayments. It's the bridge between the two systems: you keep your Medicare, but Medicaid pays some of your out-of-pocket costs. You must have Medicare and meet your state's income and asset limits to be in one.

Key Takeaways

• Medicare Savings Programs use Medicaid funds to pay your Medicare premiums and cost-sharing, but you must already have Medicare to join one.
• Income limits for Medicare Savings Programs are higher than for full Medicaid in most states, so you may may have access to for a Savings Program even if you don't may have access to for Medicaid alone.
• Each state runs its own Medicare Savings Program with different income thresholds and asset limits, so the amount you can earn and still may have access to varies by where you live.
• If you may have access to for both Medicare and full Medicaid, Medicaid becomes your primary payer and covers services Medicare doesn't, such as long-term care and dental.

When you might have both Medicare and a Medicare Savings Program

You have Medicare because you turned 65 or may have access to early. Your income is low enough that you can't comfortably pay Medicare's Part B premium (currently $164.90 per month for most people in 2024, though this changes yearly), your deductibles, or your copayments. Your state's Medicare Savings Program income limit is higher than your income.

In this situation, you apply for a Medicare Savings Program in your state. If you're approved, Medicaid pays your Part B premium directly to Medicare. Depending on which tier of the program you're in, Medicaid may also cover your Part A deductible, Part B deductible, and copayments for doctor visits and hospital stays. You still have Medicare as your primary insurance — Medicaid is just helping you afford it.

This is the most common scenario for older adults with limited income. You've worked and earned Medicare, but your retirement income (Social Security, a small pension, or savings) isn't enough to cover both living expenses and insurance costs.

When you might have both Medicare and full Medicaid

You have Medicare, and your income is low enough that you also may have access to for your state's full Medicaid program. This is rarer than having a Medicare Savings Program alone, because full Medicaid income limits are usually lower. But it happens — especially in states that expanded Medicaid or for people with very minimal income.

If you have both, Medicaid becomes your primary payer for services it covers. Medicare remains primary for hospital and doctor care, but Medicaid covers the gaps: your copayments and deductibles, plus services Medicare doesn't cover at all, such as long-term nursing home care, personal care assistance, dental work, and hearing aids (in states that include these). Medicaid also covers prescription drugs through its own formulary, separate from Medicare Part D.

Having both is powerful financially, but it also means navigating two separate systems. Your prescriptions may be covered by Medicaid instead of your Medicare drug plan. Your doctor may need to bill Medicaid first, then Medicare. You'll receive notices from both programs.

Income and asset limits vary by state and program tier

Medicare Savings Programs come in three tiers, set by federal law, but each state decides whether to offer all three and sets its own income limits within federal guidelines. The tiers are may have access to Medicare Beneficiary (QMB), Specified Low-Income Medicare Beneficiary (SLMB), and may have access to Individual (QI). QMB has the lowest income limit and covers the most costs. SLMB covers Part B premiums only. QI covers Part B premiums for people with slightly higher income.

In 2024, the federal income guideline for QMB is roughly 100% of the federal poverty level, for SLMB roughly 120%, and for QI roughly 135%. But "roughly" matters — your state may set its own limits higher or lower, and they change yearly. A person in New York might may have access to with a different income than someone in Texas.

Asset limits also vary. Some states count your savings, investments, and property (other than your home) toward a limit. Others don't count assets at all. You'll need to check your specific state's rules, usually through your state Medicaid office or the State Health Insurance Assistance Program (SHIP).

How to find out which program you might may have access to for

Start by contacting your State Health Insurance Assistance Program (SHIP). SHIP is a free, federally funded program in every state that counsels people on Medicare. They know your state's income limits, can tell you which tier you might fit into, and can walk you through the application process. You can find your state's SHIP by calling 1-800-MEDICARE or visiting the Medicare website.

You can also contact your state Medicaid office directly. They handle applications for both Medicare Savings Programs and full Medicaid. Some states let you apply online, by mail, or in person. The Medicaid office will ask for proof of income (recent pay stubs, tax returns, or Social Security statements), proof of citizenship, and proof of Medicare enrollment.

If you're already receiving Supplemental Security Income (SSI) or Supplemental Nutrition Assistance Program (SNAP) benefits, you may be automatically enrolled in a Medicare Savings Program in some states. Check with your state Medicaid office to confirm your status.

What happens to your coverage if your income changes

Medicare Savings Programs and Medicaid are based on current income, so if your income rises — through a raise, a new job, or increased Social Security — you may lose coverage. Most programs recertify your income once a year, usually around the anniversary of your enrollment. Some states do it more often.

If your income drops, you may be able to move to a different tier of the Medicare Savings Program (for example, from SLMB to QMB, which covers more). If your income rises above all three tiers, you'll lose the program but keep your Medicare. You can then buy a Medigap supplemental insurance plan if you want help with out-of-pocket costs, though Medigap premiums may be higher than the Medicare Savings Program cost-sharing you were paying.

Report income changes to your state Medicaid office as soon as they happen. Waiting until recertification and then reporting a change retroactively can result in overpayments you'll have to repay.

Medicare Savings Programs don't cover everything Medicare doesn't

A Medicare Savings Program pays your Medicare premiums and cost-sharing — the deductibles and copayments Medicare charges. It does not cover services that Medicare itself doesn't cover, such as dental work, vision care, hearing aids, or long-term nursing home care. If you need those services, you'd have to pay out of pocket unless you also may have access to for full Medicaid, which may cover some of them depending on your state.

Medicare Savings Programs also don't cover prescription drugs beyond what Medicare Part D covers. You still need to enroll in a Part D plan (or use your state's Medicaid drug coverage if you have full Medicaid). The program just helps you pay the Part D premium and cost-sharing.

Frequently Asked Questions

Can I have a Medicare Savings Program and a Medigap plan at the same time?

Technically yes, but it's usually a waste of money. A Medigap plan and a Medicare Savings Program both cover similar costs — your deductibles and copayments. If you're in a Medicare Savings Program, you don't need Medigap. If you lose the program due to income changes, then Medigap becomes a better option.

What if I'm on Medicare but my spouse is on Medicaid only?

Your spouse's Medicaid coverage is separate from yours. Your income and assets are counted together for Medicaid purposes, but your Medicare status doesn't change your spouse's may be able to access. If your combined household income is low enough, your spouse may may have access to for full Medicaid while you have Medicare and a Medicare Savings Program.

Do I have to choose between a Medicare Savings Program and full Medicaid?

No. If your income qualifies you for both, you have both. Medicaid becomes your primary payer for services it covers, and Medicare remains primary for hospital and doctor care. You don't choose one or the other — the programs coordinate.

What if my state doesn't offer all three tiers of Medicare Savings Programs?

Some states offer only QMB and SLMB, or only QMB. If your income falls into a tier your state doesn't offer, you won't may have access to for that program. Contact your state Medicaid office or SHIP to learn which tiers are available where you live and what your options are.

How long does it take to learn about I'm approved for a Medicare Savings Program?

Processing times vary by state, but most decisions come within 30 to 45 days of a complete application. Some states are faster. If you're approved, coverage usually starts the month after approval. Contact your state Medicaid office to ask about current wait times in your area.
