Can You Have Medicare and Medicaid at the Same Time? Understanding “Dual Eligibility”

If you have a limited income and are on Medicare, you might wonder: Can you have both Medicare and Medicaid?

Yes, you can. When someone qualifies for both Medicare and Medicaid, they are often called “dual eligible.” Being dual eligible can significantly reduce your out-of-pocket health care costs and expand the types of services you can access.

This guide explains how having Medicare and Medicaid together works, who may qualify, what each program covers, how they coordinate, and what it can mean for your health care and budget.


Medicare vs. Medicaid: The Basics

Before looking at how they work together, it helps to understand what each program does on its own.

What is Medicare?

Medicare is a federal health insurance program. It mainly serves:

  • People 65 or older
  • Certain younger people with disabilities
  • People with End-Stage Renal Disease (permanent kidney failure requiring dialysis or transplant)

Key parts of Medicare include:

  • Part A (Hospital Insurance):
    Covers inpatient hospital stays, skilled nursing facility care (short-term), some home health, and hospice.

  • Part B (Medical Insurance):
    Covers doctor visits, outpatient care, preventive services, durable medical equipment, and some home health.

  • Part D (Drug Coverage):
    Helps cover prescription drugs through private plans approved by Medicare.

  • Medicare Advantage (Part C):
    Private plans that bundle Part A and Part B, and often include Part D and extra benefits.

Medicare is not based on income—it’s mainly based on age or disability.

What is Medicaid?

Medicaid is a joint federal and state program that helps people with limited income and resources. It can provide comprehensive health coverage and often includes services Medicare does not cover, such as:

  • Long-term care in nursing facilities
  • Some personal care or home-and-community-based services
  • Transportation to medical appointments (in many states)
  • Some dental, vision, and hearing benefits (varies by state)

Unlike Medicare, Medicaid eligibility and benefits vary by state, within federal guidelines. Income and sometimes asset limits play a major role in determining who qualifies.


Can You Have Both Medicare and Medicaid?

Yes. You can have both Medicare and Medicaid at the same time.

When you do, you are considered “dual eligible.” This means:

  • Medicare is usually your primary coverage.
  • Medicaid acts as secondary coverage, helping pay many costs that Medicare does not fully cover.

Being dual eligible often means:

  • Lower or no Medicare premiums
  • Lower or no Medicare deductibles and coinsurance
  • Potential help with prescription drug costs
  • Access to additional services through Medicaid

Who Qualifies for Both Medicare and Medicaid?

To have both, you must independently qualify for each program.

Step 1: Qualify for Medicare

You may qualify for Medicare if:

  • You are 65 or older, and you or your spouse worked and paid Medicare taxes long enough,
    OR
  • You are under 65 and have a qualifying disability and have received disability benefits for a certain period,
    OR
  • You have End-Stage Renal Disease or certain other qualifying conditions.

Medicare eligibility is based primarily on age or disability status, not financial need.

Step 2: Qualify for Medicaid

To qualify for Medicaid, you must meet your state’s rules about:

  • Income (money you receive)
  • Resources or assets (in many states), such as savings, some property, or investments
  • Residency in that state
  • Certain category rules, such as being elderly, disabled, pregnant, or a parent, depending on the state

States may have special Medicaid programs specifically for people who already have Medicare and have low income. These are often called Medicare Savings Programs and are part of how dual eligibility works.


Levels of Dual Eligibility: Full vs. Partial

Not everyone who has both Medicare and Medicaid gets the same level of help. There are two broad types:

1. Full-Benefit Dual Eligibles

Full-benefit dual eligibles get the full Medicaid benefit package in their state, plus Medicare.

This usually means:

  • Full Medicaid coverage for services the state covers
  • Help paying Medicare Part A and/or Part B premiums, if they apply
  • Help with deductibles, coinsurance, and copayments
  • Possible coverage of long-term care and home- and community-based services

2. Partial-Benefit Dual Eligibles (Medicare Savings Programs)

Some people do not qualify for full Medicaid benefits but still get help with some Medicare costs through Medicare Savings Programs (MSPs). These are Medicaid programs specifically designed to help pay for Medicare expenses.

Common types of MSPs include:

  • QMB (Qualified Medicare Beneficiary):
    Helps pay Part A and/or Part B premiums, deductibles, coinsurance, and copayments.

  • SLMB (Specified Low-Income Medicare Beneficiary):
    Helps pay Part B premium only.

  • QI (Qualifying Individual):
    Also helps pay Part B premium for people with slightly higher income than SLMB.

  • QDWI (Qualified Disabled and Working Individual):
    Helps pay the Part A premium for certain disabled individuals who returned to work and lost premium-free Part A.

These programs can significantly lower your Medicare costs, even if you do not get full Medicaid coverage.


How Do Medicare and Medicaid Work Together?

When you have both:

  • Medicare pays first for covered services.
  • Medicaid pays second, helping with:
    • Premiums
    • Deductibles
    • Coinsurance and copays
    • Services Medicare does not cover, if your state’s Medicaid program includes them

Here’s a simple way to picture it:

SituationWho Pays First?Who May Pay the Rest?
Doctor visit covered by MedicareMedicareMedicaid (if you’re eligible)
Hospital stay under Medicare Part AMedicareMedicaid (cost-sharing help)
Prescription drugs under Part DMedicare Part DExtra help via Medicaid rules
Long-term nursing home careMedicaidMedicare (limited, short-term)
Dental/vision (if covered by state)Medicaid

Key point:
Medicaid is often described as the “payer of last resort.” That means it typically steps in only after other coverage—like Medicare—has paid its share.


What Does Each Program Cover When You Have Both?

When you’re dual eligible, you still have Medicare-covered benefits plus Medicaid-covered benefits. They often complement each other.

Medicare Generally Covers:

  • Inpatient hospital stays
  • Short-term skilled nursing facility care after a hospital stay
  • Hospice care
  • Doctor visits and outpatient services
  • Preventive care (screenings, vaccines, etc.)
  • Medically necessary equipment (like walkers or oxygen equipment)
  • Most prescription drugs under Part D or a Medicare Advantage plan with drug coverage

Medicaid May Cover:

Coverage varies by state, but often includes:

  • Long-term care in a nursing facility beyond the short-term Medicare benefit
  • Home- and community-based services, like personal care, assistance with daily activities, adult day health, and sometimes home modifications
  • Dental, vision, and hearing services, where offered
  • Non-emergency medical transportation to appointments (in many states)
  • Some behavioral health and substance use services beyond what Medicare covers
  • Additional help with copays and cost sharing

In many situations, dual eligibility can fill in important gaps in Medicare coverage.


How Prescription Drug Coverage Works for Dual Eligibles

If you have both Medicare and Medicaid, your prescription drug coverage usually comes through Medicare Part D, not through Medicaid.

Medicaid may:

  • Help with Part D premiums (depending on your level of dual eligibility)
  • Reduce your copays for medications
  • Provide some coverage for drugs or services that fall outside standard Part D formularies, depending on the state

⚠️ Important:
If you’re dual eligible, you typically must be enrolled in a Medicare Part D plan (either stand-alone or through a Medicare Advantage plan) to get full help with prescription costs.


Dual Eligible Special Needs Plans (D-SNPs)

Some people with both Medicare and Medicaid enroll in a specific type of Medicare Advantage plan called a Dual Eligible Special Needs Plan (D-SNP).

D-SNPs are designed for people who have both Medicare and Medicaid and often:

  • Coordinate benefits between the two programs
  • Offer care management and support services
  • May bundle extra benefits, like transportation, meal programs, or vision/dental, aligned with Medicaid offerings
  • Work with your state Medicaid program to reduce confusion about who pays for what

Not all areas have D-SNPs, and not everyone will want or need one, but they can be an option for some dual-eligible individuals.


Financial Help: Premiums, Deductibles, and Copays

One of the biggest advantages of being dual eligible is financial protection from many Medicare costs.

Depending on your level of dual eligibility, Medicaid may:

  • Pay your Medicare Part B premium
  • Pay your Medicare Part A premium, if you have one
  • Cover deductibles and coinsurance for hospital and medical services
  • Reduce or eliminate copays for covered services
  • Lower your prescription drug costs

Many people find that, once they become dual eligible, their monthly health care spending becomes more predictable and manageable.


How to Apply for Medicare and Medicaid

Applying for Medicare

People are typically:

  • Automatically enrolled in Medicare when they reach 65 and are already receiving Social Security or certain disability benefits,
    OR
  • Able to sign up through the Social Security Administration during designated enrollment periods.

If you have questions about your Medicare eligibility or enrollment, you can contact Social Security or Medicare directly, or speak with a local benefits counselor.

Applying for Medicaid

To apply for Medicaid, you usually:

  1. Contact your state Medicaid office or apply using your state’s online portal.
  2. Provide information about:
    • Your income
    • Your assets or resources (if your state counts these)
    • Your household size
    • Your residency and immigration status as required
  3. Submit supporting documents, such as:
    • Pay stubs or benefit award letters
    • Bank statements (if required)
    • Identification and proof of address

If you already have Medicare and your income is limited, you can ask specifically about:

  • Full Medicaid coverage, and
  • Medicare Savings Programs (QMB, SLMB, QI, or QDWI)

Many communities have local assistance programs, legal aid organizations, or aging and disability resource centers that can help you navigate the paperwork.


Common Benefits and Challenges of Having Both

Potential Benefits

People who are dual eligible often experience:

  • Lower out-of-pocket costs for hospital and doctor visits
  • Better access to prescription medications
  • Coverage for long-term care or in-home supports that Medicare does not provide
  • Additional benefits, such as transportation, personal care, or dental/vision where state Medicaid allows

This combination can make it easier to manage chronic conditions, stay in the community longer, and reduce financial stress from medical bills.

Potential Challenges

At the same time, there can be challenges:

  • Complexity:
    Understanding two separate programs with different rules can feel confusing.

  • Provider networks:
    Not all providers accept both Medicare and Medicaid. You may need to confirm that a doctor, specialist, or facility participates in both programs if you want Medicaid to help with costs.

  • State variation:
    Medicaid rules differ from state to state, so what is covered and how much help you receive can vary widely.

Because of this complexity, many people find it helpful to seek one-on-one guidance from a local benefits counselor, social worker, or similar resource.


Key Takeaways: Medicare and Medicaid Together

Here is a quick summary to keep in mind:

  • Yes, you can have both Medicare and Medicaid.
    When you do, you are considered dual eligible.

  • Medicare is primary; Medicaid is secondary.
    Medicare pays first for covered services, and Medicaid may help with remaining costs and extra benefits.

  • Dual eligibility can significantly reduce your health care costs.
    It may cover premiums, deductibles, copays, and services Medicare does not pay for.

  • Coverage and rules vary by state.
    Medicaid benefits are not the same everywhere, and income/resource limits differ by state.

  • You must qualify for both programs separately.
    Medicare depends on age or disability; Medicaid depends on income, assets (in many cases), and state-specific criteria.

  • Help is available.
    Local assistance programs, benefits counselors, and social service agencies can help you understand your options and complete applications.


Having both Medicare and Medicaid can create a more complete safety net, especially if you live on a limited income and need ongoing health care or long-term support. Understanding how these two programs work together can help you make informed decisions and take full advantage of the coverage you are eligible to receive.
