Who Is Eligible for Both Medicare and Medicaid?
Who is eligible for both Medicare and Medicaid? Usually, it is someone who qualifies for Medicare because of age or disability and also meets their state's rules for Medicaid or a Medicare Savings Program. Having both types of coverage is often called being dually eligible. The programs work together, but they do not have the same eligibility rules or pay for the same services.
This guide explains the common pathways to dual eligibility, how the two programs coordinate, what help may be available with Medicare costs, and why your state Medicaid agency must make the final eligibility decision. For a plain-language overview of Medicare choices, you can also review Grey State Financial's Medicare Made Simple guide.
What does it mean to be eligible for both Medicare and Medicaid?
Dual eligibility means a person has Medicare and Medicaid at the same time, or has Medicare plus help from a Medicare Savings Program administered through their state. The level of Medicaid assistance can differ from person to person. Some people receive full-benefit Medicaid, while others receive limited help with Medicare premiums or cost-sharing.
Medicare is federal health insurance for people age 65 and older and for some younger people who qualify because of a disability, end-stage renal disease, or amyotrophic lateral sclerosis. Medicaid is a joint federal and state program. It can help eligible people with limited income and resources, older adults, people with disabilities, and other groups covered under their state's rules.
These programs should not be treated as interchangeable. Medicare eligibility does not automatically qualify someone for Medicaid. Likewise, Medicaid eligibility does not automatically mean a person is eligible for every Medicare benefit. The state Medicaid agency reviews the person's application and determines which category of help applies.
Who may qualify for both programs?
There is no single national checklist that guarantees dual eligibility because Medicaid rules vary by state. However, most people who receive both programs fit one of these broad pathways:
- Adults age 65 or older with limited income or resources. A person may qualify for Medicare based on age and qualify for Medicaid or a Medicare Savings Program under the financial and other rules in their state.
- People under age 65 who qualify for Medicare because of a disability. Medicaid pathways for people with disabilities may consider income, resources, disability status, functional needs, and other state requirements.
- People who need long-term services and supports. Medicaid may cover certain nursing facility services, home- and community-based services, or personal care that Medicare generally does not cover in the same way. A long-term-care Medicaid pathway often has its own financial and functional rules.
- People who qualify for Medicare Savings Program assistance. A state may help pay Medicare premiums and, depending on the program, Medicare deductibles, coinsurance, and copayments. This assistance can create partial dual eligibility even when a person does not receive full Medicaid benefits.
Other factors may include state residency, household circumstances, immigration or citizenship rules that apply to the program, and whether the person has countable income or resources under the state's method. Eligibility can also change when income, assets, household size, disability status, or care needs change.
Which Medicare Savings Programs can help with Medicare costs?
Medicare Savings Programs, or MSPs, are state-administered programs that can help eligible Medicare beneficiaries with certain Medicare expenses. The four main program names are useful starting points, but the state that processes the application determines whether you qualify and what the program pays.
| Program | What it may help pay | Important qualification note |
|---|---|---|
| Qualified Medicare Beneficiary, or QMB | Part A premiums when applicable, Part B premiums, and Medicare-covered deductibles, coinsurance, and copayments | Income and resource rules apply. Providers generally cannot bill a QMB beneficiary for Medicare-covered cost-sharing, although a small Medicaid copayment may apply in some circumstances. |
| Specified Low-Income Medicare Beneficiary, or SLMB | Part B premiums | Generally requires enrollment in both Part A and Part B, along with meeting the applicable financial rules. |
| Qualifying Individual, or QI | Part B premiums | Funding is limited and applications are handled by the state. A person generally must have Part A and Part B and meet the applicable financial rules. |
| Qualified Disabled and Working Individual, or QDWI | Part A premiums | Designed for certain disabled working people who lost premium-free Part A after returning to work. Special income, resource, and work-related rules apply. |
Medicare.gov explains the Medicare Savings Programs and current federal guidelines, but those figures are not a substitute for a state determination. Some states use more generous limits or disregard certain types or amounts of income and resources. Even if you think your income or assets are too high, applying may still be worthwhile.
How do Medicare and Medicaid coordinate coverage?
When a person has both programs, Medicare generally pays first for Medicare-covered services. Medicaid generally pays last, after Medicare and other health insurance. Depending on the person's category of Medicaid assistance and state rules, Medicaid may then help with Medicare premiums, deductibles, coinsurance, or copayments.
Medicaid can also cover services that Medicare does not normally cover or does not cover to the same extent. Examples may include certain long-term nursing facility services, home- and community-based supports, personal care, eyeglasses, hearing-related benefits, or other state-approved services. Coverage is not identical in every state, and a service must still meet the program's coverage and authorization rules.
This coordination does not mean every bill is automatically paid in full. The result depends on the person's Medicare coverage, Medicaid category, provider participation, state payment limits, and the service received. Ask the provider to bill both programs and keep the Medicare Summary Notice, Medicaid notices, and other coverage documents.
Can someone with both programs choose Medicare Advantage?
People who are eligible for Medicare and Medicaid may generally choose between Original Medicare and Medicare Advantage, subject to enrollment rules and plan availability. Some Medicare Advantage plans are designed specifically for people with both Medicare and Medicaid. These are called Dual Eligible Special Needs Plans, or D-SNPs.
A D-SNP may coordinate Medicare and Medicaid benefits, but plan availability, eligibility requirements, provider networks, covered services, and enrollment options vary by location. Having Medicaid does not mean every D-SNP accepts the person, and joining a plan does not replace the need to maintain Medicaid eligibility when the plan requires it.
Before choosing a plan, confirm whether the plan includes the person's doctors, hospitals, prescriptions, and Medicaid coordination. Grey State Financial's Medicare Advantage information can help explain the broader plan structure. A licensed agent can compare available options, but the state Medicaid agency remains the authority for Medicaid eligibility and benefits.
Does dual eligibility help with prescription drug costs?
Many people with full-benefit Medicaid or Medicare Savings Program assistance receive automatic help with Medicare prescription drug costs through the Extra Help program. Extra Help can reduce Part D premiums, deductibles, coinsurance, and other drug costs. Some people qualify automatically, while others need to apply.
Medicare.gov says people with full-benefit Medicaid, help from their state paying Part B premiums through an MSP, or Supplemental Security Income may get Extra Help automatically. If you have both Medicare and Medicaid, Medicare generally covers your prescription drugs through Part D. Medicaid may still cover certain drugs or services Medicare does not cover, depending on the circumstances and state rules.
Read more about Extra Help and Medicare drug costs. If you already have Part D coverage, review notices about your plan and drug costs. You can also review Grey State Financial's Medicare Part D information for a general explanation of formularies and plan comparisons.
Why do state rules matter so much?
Medicaid eligibility is not determined by Medicare.gov alone. Each state administers its Medicaid program within federal requirements, and states can differ in income limits, resource rules, pathways, spend-down policies, covered services, application processes, renewal procedures, and the way Medicare Savings Programs are structured.
For example, Arizona's AHCCCS publishes state-specific information about the Qualified Medicare Beneficiary program. Virginia's Department of Medical Assistance Services publishes a separate Medicare Savings Programs fact sheet. These materials illustrate why someone should use the rules and application instructions for the state where they live, rather than copy a neighbor's eligibility result or rely on a national income chart alone.
Use Medicaid.gov's state overview directory to find the appropriate state agency and learn how to apply. If you move, your Medicaid eligibility and application may need to be reviewed under the new state's rules.
How do you apply for Medicaid or Medicare Savings Program help?
- Confirm your Medicare status. Gather your Medicare card and identify whether you have Part A, Part B, or both. Some MSPs require both parts.
- Gather financial and household information. The state may ask about income, bank accounts, investments, property, household size, insurance, disability, and other factors. The exact list depends on the program.
- Contact the state Medicaid or Medical Assistance office. Apply through the state agency or the application channel it identifies. Ask specifically about full-benefit Medicaid and Medicare Savings Programs.
- Ask about related assistance. If you qualify for Medicaid or an MSP, ask how Extra Help, transportation, long-term services, personal care, or other state benefits may interact with your coverage.
- Read the decision notice carefully. If the state denies coverage or approves a different category than expected, the notice should explain the result and any appeal or reconsideration rights. Follow the deadline on the notice.
A State Health Insurance Assistance Program, or SHIP, can provide free, unbiased Medicare counseling. A Medicare insurance brokerage can help explain available Medicare plan choices, but it cannot approve Medicaid or change a state's eligibility decision.
What should you compare after you qualify?
Once you know which benefits you have, check how your Medicare and Medicaid coverage fit together. Consider whether your doctors and hospitals participate, whether prescriptions are covered, how referrals work, whether transportation or dental benefits are included, and whether the plan coordinates with your Medicaid category.
Do not select a plan only because it advertises a $0 premium or extra benefits. A plan can still have copayments, network rules, prior authorization requirements, or limits on supplemental benefits. A careful comparison should look at the full combination of cost, coverage, providers, prescriptions, and support.
Grey State Financial is an independent brokerage. Its agents compare available Medicare options from represented carriers and explain trade-offs at no cost to the client because agents are compensated by insurance carriers, not by the client. Medicaid eligibility and benefits remain controlled by the state agency.
Frequently asked questions
Can I have Medicare and Medicaid at the same time?
Yes. If you qualify for Medicare and also meet your state's Medicaid or Medicare Savings Program rules, you can have both. The amount and type of Medicaid help vary by eligibility category and state.
Does Medicaid pay my Medicare Part B premium?
It may. Full-benefit Medicaid or a Medicare Savings Program can pay Part B premiums for eligible people. The state agency determines whether you qualify and which program applies.
Do I need both Medicare Part A and Part B to qualify for Medicaid?
Not necessarily. Medicaid eligibility rules are state-specific. Some Medicare Savings Programs, including SLMB and QI, generally require both Part A and Part B. Ask your state Medicaid agency which pathway applies to your situation.
Will Medicaid pay all of my Medicare bills?
Not always. Medicare usually pays first, and Medicaid may help with premiums and Medicare cost-sharing based on your category of assistance and state rules. Providers, services, and state payment limits can affect what is covered.
Can I lose Medicaid while keeping Medicare?
Yes. Medicare and Medicaid have separate eligibility and renewal rules. A change in income, resources, household circumstances, disability status, residency, or renewal paperwork can affect Medicaid while Medicare continues.
Where can I find out if I qualify?
Contact the Medicaid or Medical Assistance agency in your state and ask about full-benefit Medicaid and Medicare Savings Programs. You can also use Medicare.gov for program information and your local SHIP for free Medicare counseling.
