What’s the difference between Medicare and Medicaid?

Blog Resources What’s the difference between Medicare and Medicaid?

If you’ve ever mixed up Medicare and Medicaid, you’re not alone.

Even reporters, policymakers, and people who work inside these programs get them confused, partly because the names sound alike, and partly because the systems themselves are built in ways that make confusion almost inevitable.

These programs touch nearly every kind of care, from aging and disability to child care and the systems families rely on when someone needs help. Knowing how they actually work can change the choices we make for ourselves and the people we love.

In this blog, we’ll break down what each program covers, how they work together, and the most common points of confusion.

What is Medicare?

Medicare is a federal health insurance program that is administered entirely by the federal government, which means it works the same way no matter what state you live in. It primarily covers people 65 and older. People under 65 with disabilities can also qualify through Social Security Disability Insurance (SSDI), though SSDI has very strict eligibility requirements, so this path isn’t as accessible as it might sound. It helps cover hospital stays, doctor’s visits, prescriptions, and preventative care, but does not cover most long-term care.

What is Medicaid?

Medicaid is a health and long-term care coverage program that covers 1 in 5 people in the United States. Unlike Medicare, it’s a federal-state partnership. The federal government finances about two-thirds of Medicaid spending on average, but states run the program. That means eligibility requirements (outside of the minimum set by Federal law), what’s covered, and even the name of the program can look different depending on where you live. It covers a much wider range of care than Medicare, including most long-term care, which is one of the biggest differences between the two.

A side-by-side comparison of what these programs cover:

What’s Covered	Medicare	Medicaid
Hospital stays	✓	✓
Doctor visits	✓	✓
Prescription drugs	✓	✓
Preventive screenings	✓	✓
Short-term skilled nursing (post-hospital)	✓	✓
Hospice care	✓	✓
Dental and vision care	✗	✓ (most states)
Long-term home care (outside of short-term rehabilitation)	✗	✓
Personal care aides	✗	✓
Nursing facility care (long-term)	✗	✓
Home and community-based services	✗	✓
Assistive technology	✗	✓
Caregiver support programs	✗	✓

It’s totally understandable to still have questions about the differences. The side-by-side comparison makes it look straightforward. But in practice, these two programs trip people up all the time – even people who work in health care.

Here are the most common points of confusion:

Q: “When I need long-term care, I’ll be able to get it through Medicare.”

This is the most common mix-up and one of the most costly. Medicare covers short-term recovery, like skilled nursing after a hospital stay or some home health visits following a procedure. But it does not cover the kind of ongoing, day-to-day support that makes it possible to age at home – things like help with bathing, dressing, cooking, and managing medications over the long haul, outside of a very narrow home health benefit. Medicaid does.

Q: “My coverage has a different name, so I don’t think I’m covered by Medicaid.”

You might be on Medicaid and not even know it. Every state runs its Medicaid program under a different name. In California, it’s Medi-Cal. In Massachusetts, it’s MassHealth. In Tennessee, TennCare. In Oklahoma, SoonerCare. In Kansas, KanCare. Same federal program, different name in almost every state, which is a big part of why this gets so confusing. If you’re unsure whether you or a family member is enrolled, it’s worth checking with your state directly.

Q: “Medicare and Medicaid are totally separate.”

Not always. Some people are enrolled in both, and for good reason. This is called being “dually eligible.” This is most common among older adults and people with disabilities who rely on Medicare for general health coverage and on Medicaid to fill gaps in coverage for long-term care, premiums, transportation, co-pays, and medical equipment.

Sharon, a mother in Michigan, knows this firsthand:

“My 45-year-old son has Down Syndrome. He receives Social Security and Medicare through his retired father. Medicaid pays for his Medicare premiums, prescriptions, and what Medicare does not cover. It also provides home help care so he can continue receiving the support he needs.”

Sharon’s family relies on both programs working together, which is why cuts to either one ripple through millions of households like hers.

Q: “People with disabilities under 65 can easily get Medicare.”

Not quite. People under 65 with disabilities can qualify for Medicare through Social Security Disability Insurance (SSDI), but SSDI has very strict eligibility requirements, and the process can be long and difficult to navigate. For many people with disabilities, Medicaid is a more accessible path to coverage, including for the home and community-based services (HCBS) that allow them to live independently. More than 7.8 million people with disabilities and older adults rely on Medicaid-funded HCBS programs to live in their own homes and communities.

Q: “Medicaid doesn’t really affect me and is only for low-income people.”

For most families, Medicaid isn’t just a program for people with low income; it’s the program most families will eventually depend on, regardless of income, when a parent, spouse, or family member needs ongoing long-term care. An average American turning 65 today is estimated to face $120,900 in future long-term care costs – a steep cost that most Americans are unable to cover out of pocket.

Why this matters right now

Understanding the differences between Medicaid and Medicare is the first step. But there’s something else everyone navigating care needs to know: the system that makes all of this possible is under serious threat.

The need for care is growing fast. Every day, 10,000 people in the United States turn 65 – meaning people are entering the stage of life where long-term care becomes a real possibility. At the same time, a nationwide shortage of care workers is making it harder for families to find reliable, affordable support. This has resulted in more families needing care, fewer workers available to provide it, and most of the high costs landing on those giving or receiving care.

On top of all of this, federal legislation passed last year cut more than $1 trillion from Medicaid, Medicare, and the Affordable Care Act (ACA) – the largest cuts in the nation’s history. States are now making budget decisions that will determine whether home and community-based services (HCBS) — the programs that allow people to receive care at home instead of in a nursing facility — survive or get cut. HCBS programs are classified as “optional” under federal law. This means when state budgets get tight, these programs are often the first things to be cut. This has happened before, it’s happening now, and it will keep happening without pushback.

These choices are landing directly on families. Katherine, who lives in Georgia, shared what that looks like in her household:

“My husband and I are both disabled and now we have to pay the Medicare payment every month because they cut us off of Medicaid. That took $400 out of our checks total plus we have to pay for diabetes supplies, migraine supplies, and heart failure care. We can’t afford everything we need now.”

Katherine and her husband aren’t alone. Cuts at the federal level are forcing families across the country into impossible trade-offs.

People across the country understand what’s at stake. 90 percent of people believe there should be no cuts to home and community-based services (HCBS), and a majority want increased funding. 88 percent of voters support expanding Medicare to cover long-term, in-home care.

The demand for something better is already there. What’s missing is the political will to match it — and that changes when enough of us refuse to let these programs be quietly dismantled.
