MassHealth Explained: How It Relates to Medicaid and Medicare in Massachusetts

If you live in Massachusetts and are trying to understand your health coverage options, you’ve probably heard the term MassHealth and wondered: Is MassHealth Medicaid or Medicare?

The short answer is: MassHealth is Massachusetts’ Medicaid program (and also includes a Children’s Health Insurance Program component). It is not Medicare.

However, many people who qualify for Medicare may also have MassHealth at the same time, which can make things confusing. This guide breaks it all down in clear, practical terms.

What Is MassHealth?

MassHealth is the name Massachusetts uses for its Medicaid and Children’s Health Insurance Program (CHIP) coverage.

In other words:

• MassHealth = Massachusetts’ version of Medicaid (plus coverage for many children through CHIP).
• It is a state and federally funded program that helps eligible residents with low or moderate incomes get health insurance.

MassHealth is managed by the state, but it follows general federal Medicaid rules. The state has some flexibility in who qualifies and what’s covered, which is why it has its own name and specific rules.

Is MassHealth Medicaid or Medicare?

Direct answer

• MassHealth is Medicaid (and CHIP), not Medicare.
• Medicare is a separate federal program, mostly for people 65 and older or certain younger individuals with disabilities.

They are two different programs with different eligibility rules, funding sources, and benefits.

However, in Massachusetts, many people:

• Only have MassHealth, or
• Only have Medicare, or
• Have both Medicare and MassHealth (often called “dual eligible”).

That overlap is where the confusion usually comes from.

Quick Comparison: MassHealth vs. Medicare

Here’s a simple side‑by‑side summary:

Understanding Medicaid in Massachusetts (MassHealth)

How MassHealth relates to Medicaid

Across the United States, each state runs its own Medicaid program under a federal‑state partnership. Instead of calling it just “Medicaid,” Massachusetts uses the name MassHealth.

So when someone says:

• “I’m on Medicaid in Massachusetts”
  they are usually talking about MassHealth.

Who MassHealth is generally for

While exact rules are detailed and can change over time, MassHealth generally serves:

• Children and teens
• Pregnant people
• Parents and caretakers of minor children
• Adults with low incomes
• People with disabilities
• Some older adults, including those who also have Medicare

Eligibility often depends on:

• Household income
• Household size
• Immigration status (with specific rules and exceptions)
• Age or disability status
• Other special categories (such as long-term care needs)

The state uses these factors to decide which MassHealth plan someone qualifies for and what it will cover.

What Is Medicare, and How Is It Different?

Medicare in simple terms

Medicare is a federal health insurance program, not specific to Massachusetts. It mainly serves:

• People 65 or older
• Some younger individuals with certain long-term disabilities or medical conditions

Unlike Medicaid/MassHealth, Medicare is not primarily income-based. Many people qualify based on age or work history, regardless of income.

The parts of Medicare

Medicare is divided into components:

• Part A – Hospital insurance (inpatient hospital care, skilled nursing facility care, some home health, hospice)
• Part B – Medical insurance (doctor visits, outpatient care, preventive services, some medical supplies)
• Part D – Prescription drug coverage (through private drug plans approved by Medicare)
• Medicare Advantage (Part C) – Alternative to Original Medicare offered through private plans that bundle A and B, and often D

Medicare and MassHealth can work together for people who qualify for both, but they remain separate programs with different rules.

Can You Have Both MassHealth and Medicare?

Yes. Many people in Massachusetts are “dual eligible,” meaning they have both Medicare and MassHealth.

Typically, this happens when:

• Someone becomes eligible for Medicare due to age or disability, and
• Their income and resources are low enough to qualify for MassHealth as well.

How they work together

In very general terms:

• Medicare pays first for covered services.
• MassHealth may pay second, helping with:
  • Premiums
  • Certain copays or deductibles
  • Some services that Medicare may not fully cover, depending on the MassHealth category and program rules

For many dual‑eligible individuals, having both can significantly reduce their out‑of‑pocket health costs and expand what’s covered, especially for services like long‑term care.

Key Differences: Eligibility, Coverage, and Costs

Understanding exactly how MassHealth and Medicare differ can help you figure out what you might qualify for and how your benefits work.

1. Eligibility

MassHealth (Medicaid in MA)
Typically based on:

• Income and household size
• Specific categories (children, adults, pregnant people, older adults, people with disabilities)
• State-defined income limits that can vary by group

Medicare

Typically based on:

• Age 65+
• Or certain disabilities, end-stage renal disease, or similar qualifying medical situations
• Usually linked to work history and payment of Medicare taxes (for premium-free Part A)

Income does not determine basic Medicare eligibility, though it can affect premiums and whether someone qualifies for extra help.

2. What they cover

MassHealth may cover (varies by category and program):

• Primary and specialty care
• Hospital stays and emergency services
• Behavioral health and substance use services
• Prescription drugs
• Laboratory tests and imaging
• Some vision and dental services
• Some long-term services and supports (home care, nursing facilities, personal care in certain cases)

Medicare generally covers:

• Part A: Inpatient hospital care, skilled nursing facility care (short-term), some home health care, hospice
• Part B: Doctor visits, outpatient services, preventive care, durable medical equipment
• Part D or Medicare Advantage: Prescription drugs, depending on the plan

Compared broadly, MassHealth is often more comprehensive for low-income residents, especially for services like long‑term care, though details depend on your exact plan and eligibility group.

3. Costs to you

MassHealth costs can include:

• No or low monthly premiums for many people
• Possible small copayments for some services or medications
• Some individuals with higher incomes may pay higher premiums or share of cost, depending on their specific program

Medicare costs can include:

• Part A: Often no premium if enough work credits; deductible for hospital stays
• Part B: Monthly premium, plus deductibles and coinsurance
• Part D and Medicare Advantage: Plan-specific premiums, copays, and deductibles

For people with both:

• MassHealth can help pay some Medicare premiums and cost-sharing, depending on the level of MassHealth eligibility.

Common MassHealth-Related Terms You Might Hear

To cut through the jargon, here are a few terms often mentioned in Massachusetts:

• MassHealth Standard – One of the most comprehensive types of MassHealth coverage, often for children, certain adults, people with disabilities, and some older adults.
• MassHealth CommonHealth – Coverage for certain disabled adults and children who may not meet income limits for other MassHealth categories but meet disability criteria and other requirements.
• MassHealth CarePlus – Coverage for many low-income adults who meet specific eligibility criteria.
• Children’s coverage (CHIP) – Often grouped under MassHealth for children in families whose income may be too high for traditional Medicaid but still within certain limits.

These are MassHealth plan types, not Medicare plans.

How to Tell If You Have MassHealth, Medicare, or Both

If you’re unsure what you have, you’re not alone. Many people carry multiple cards and are not sure what each does.

Here are some ways to check:

1. Look at your insurance card(s)

   • A card with “MassHealth” on it refers to your Massachusetts Medicaid coverage.
   • A card with “Medicare” and a Medicare number is for your federal Medicare coverage.
   • You might also have a separate card from a Medicare Advantage or Medicare Part D plan.

2. Check your eligibility letters or notices

   • Letters labeled from MassHealth typically discuss your Medicaid benefits.
   • Letters from Medicare or the Social Security Administration relate to your Medicare benefits.

3. Ask your provider’s billing office

   • Many medical offices are familiar with both programs and can tell you which they are billing.

4. Review renewal or enrollment forms

   • MassHealth renewals and notices come from the state of Massachusetts.
   • Medicare enrollment documents are federal.

When You Might Interact With Both Programs

You might come across both MassHealth and Medicare when:

• You turn 65 and already have MassHealth
• You are under 65 and receive disability benefits that qualify you for Medicare, while you also meet income and other criteria for MassHealth
• You move to a nursing facility or need long‑term care services that involve coordination between the two

In these situations, you may:

• Continue using Medicare for core hospital and medical services
• Use MassHealth to help pay costs and expand coverage, depending on what you qualify for

Simple Takeaways: Is MassHealth Medicaid or Medicare?

To wrap it up clearly:

• MassHealth is Massachusetts’ Medicaid (and CHIP) program.
• MassHealth is not Medicare.
• Medicare is a separate, federal program mainly for people 65+ and certain disabled individuals.
• Many people in Massachusetts may have both MassHealth and Medicare, and in those cases, the programs usually coordinate:
  • Medicare pays first
  • MassHealth may help with some costs and extra benefits

Understanding this distinction can help you:

• Know which card to show when getting care
• Better understand your bills, copays, and coverage
• Ask more precise questions when speaking with customer service or enrollment staff

If you are unsure which program you qualify for or how your current coverage works, it can be helpful to:

• Gather your insurance cards and recent letters
• Contact the customer service numbers on those cards
• Ask specifically whether your coverage is MassHealth (Medicaid in MA), Medicare, or both

That clarity makes it much easier to navigate your care, avoid surprises, and make the most of the benefits available to you.
