Medicaid vs Medicare: the one test that tells them apart
In short: Medicare is federal health insurance tied to your age or a disability, not your income. Medicaid is health coverage run by your state for people with limited income and assets. A person can qualify for both at once, and millions do.
If your mother just turned 65 and got a Medicare card in the mail, and then a hospital social worker mentioned Medicaid in the same breath, the mix-up is not a sign you've missed something. The names rhyme on purpose. Congress created both programmes the same year, 1965, one running through the federal government and one through the states, and nobody in a hospital hallway has time to explain which is which before you're signing something (Medicaid.gov).
For a lot of families, though, the real work isn't figuring out which programme pays. It's chasing the referral that never got booked, or the equipment that was ordered and hasn't shown up. If your parent is on Medicare and that's the part eating your evenings, a navigator can take it off your list. Navigate Care explains what that looks like and what it may cost on its what you will pay page.
What Medicare actually is, and who gets it
Medicare doesn't look at your bank account. Medicare.gov puts it plainly: "Medicare is federal health insurance for anyone age 65 and older, and some people under 65 with certain disabilities or conditions." Run the same way in Alaska as in Alabama. One set of rules, administered by the Centers for Medicare & Medicaid Services, and none of it changes because your parent crosses a state line.
There are two doors into it. Most people walk through the first one: they turn 65, and if they or a spouse paid Medicare taxes long enough while working, they sign up through Social Security. The second door is younger people with a qualifying disability or condition. One well-defined example: end-stage renal disease. Medicare.gov says a person with kidney failure needing regular dialysis or a transplant "can get Medicare no matter how old you are," and for someone on dialysis, coverage usually starts the first day of the fourth month of treatment.
What Medicare pays for once you're in is a separate question from eligibility, and it's the one most families actually care about day to day. Original Medicare is split into Part A, mostly hospital stays, and Part B, mostly everything outside a hospital bed: doctor visits, outpatient care, tests and durable medical equipment. Our guide on Medicare Part B goes through its 2026 premium, deductible and 20% coinsurance in detail. The short version here: Medicare pays well for hospital stays, doctor visits, tests and medical equipment. It generally does not pay for custodial help, the kind where someone comes to bathe or dress your parent and that's the only care being given. That gap is where Medicaid, and the rest of this post, comes in.
There's a Part C and a Part D too. Part C, Medicare Advantage, is a private-plan route that has to cover at least what Original Medicare covers. Part D is prescription drug coverage. Neither changes who is eligible for Medicare in the first place; they're ways of getting the same underlying benefit. If your parent is choosing between Original Medicare and an Advantage plan, our guide to Medicare parts explained is a better place to work through that decision than this post.
What Medicaid actually is, and who gets it
Medicaid is the other half of the 1965 deal, and it was built for a different job. Medicaid.gov describes it as a programme "designed to provide health coverage for low-income people." It's a federal-state partnership: Washington sets the floor, but each state runs its own programme, decides who qualifies beyond the federal minimum groups, and sets its own income and asset limits.
That last part matters more than it sounds. Because states genuinely differ, Medicaid's own site won't give you one national number to check your parent against. Medicaid.gov's eligibility page says flatly: "To find out for sure if you're eligible for Medicaid, you must contact your state Medicaid agency." That's not a brush-off. It's the honest answer, and it's also not legal or financial advice, which is a job for that state agency or a State Health Insurance Assistance Program (SHIP) counsellor, not for a navigator or for us.
Children, pregnant people, parents of dependent children, and people who are elderly, blind or disabled are the groups every state's Medicaid programme has to cover in some form. Many states cover more besides. Income and assets both count, and for older adults applying because of a nursing home or home care need, the asset test is where things get specific, which is its own section below.
What separates the two programmes
| Medicare | Medicaid | |
|---|---|---|
| Who runs it | The federal government, the same nationwide | Each state, inside federal minimum rules |
| How you qualify | Age 65+, or a disability/condition at any age | Limited income and assets; groups vary by state |
| Where you apply | Social Security | Your state Medicaid agency |
| 2026 Part A premium | $0 a month for most; $311 or $565 if you haven't paid enough Medicare taxes | Set by the state; many pay no premium at all |
| What it's strong on | Hospital care, doctor visits, Part B outpatient care, equipment | Long-term nursing facility and home-based care, for those who qualify |

Can your parent have both? Dual eligibility, explained
Yes, and it's common enough to have its own name. CMS runs a Medicare-Medicaid Coordination Office specifically for "people who are dually enrolled in both Medicare and Medicaid, also known as dually eligible individuals or Medicare-Medicaid enrollees" (CMS). In 2026, that's about 12 million people nationally, 8,609,461 getting full Medicaid benefits on top of Medicare and another 3,465,609 getting help with premiums and cost-sharing only (KFF). That's more overlap than most families assume.
That second, smaller group is worth knowing about even if your parent would never qualify for full Medicaid. The Medicare Savings Programs let a state pick up some or all of a parent's Medicare costs, premium included, for people whose income is low but not low enough for full Medicaid. For 2026, the monthly income limits are roughly $1,350 for a single person and $1,824 for a married couple at the most generous level (QMB), down to $1,816 single and $2,455 married at the most limited one (QI), with a resource limit around $9,950 single and $14,910 for a couple. Our guide on Medicare Savings Programs and Extra Help walks through QMB, SLMB and QI, the three levels, and what each one covers, and confirms those figures and how to apply through your state.
When Medicare and Medicaid both apply to the same bill, Medicare pays first, as the primary payer, and Medicaid picks up some or all of what's left, depending on the service and the state. None of this happens automatically just because your parent is on both. Dual status has to be established and kept current with the state Medicaid agency.
Where the two really split: long-term care
Here's the part that sends most families looking up "Medicaid vs Medicare" in the first place: paying for a nursing home. Medicare's coverage of a skilled nursing facility stay is short-term and tied to a hospital stay; our guide on whether Medicare pays for help at home explains what it does and doesn't stretch to. Long, ongoing custodial care in a nursing facility is generally outside what Medicare pays for at all.
Medicaid is the programme that can pay for that, but only for people who meet the income and asset test, and getting there is not as simple as applying the week care starts. Federal rules set a 60-month look-back period, five years, on asset transfers for anyone applying for Medicaid-paid nursing facility care (Texas Health and Human Services). The state looks at the five years before the application date and checks whether money or property was given away, or sold for less than it was worth. Most states use that five-year window, though a few set theirs differently.
If a transfer like that turns up, Medicaid doesn't refuse coverage outright. It withholds payment for a stretch of time called a penalty period, worked out by dividing the amount given away by the average daily cost of nursing facility care in that state. There's no cap on how long that penalty period can run, either.
Here's how the arithmetic works, with round numbers for illustration only, not a real transfer or a real state rate. Say your parent gave away $10,000 within the look-back window, and nursing facility care in that state works out to $500 a day. Dividing the gift by the daily rate gives 20, so Medicaid would not pay for 20 days of care it otherwise would have covered. Change either number and the penalty changes with it. That's the whole mechanism; the only real variables are the amount transferred and the state's own daily rate.
None of this is a reason to make a decision under pressure, and we're not the ones to make it with you. A question about gifting, trusts or how the look-back applies to your parent's specific situation is a legal and financial one. SHIP counselling is free, and an elder law attorney or your state Medicaid office are the right places to ask it, well before a nursing home placement is on the table.
Which one do you call first, if you're still not sure
You don't have to map the whole system before you pick up a phone. A short routine gets most families to the right door.
- Is your parent 65 or older, or do they have a qualifying disability or ESRD? If yes, Medicare is already part of the picture, whether or not they've used it much yet.
- Is the question about a hospital stay, a doctor visit, equipment, or a test? That's Medicare territory. Start with the Medicare Part B guide, or with a denial letter if one arrived.
- Is the question about ongoing help at home, or a nursing facility stay that's starting to look long-term rather than short? That's an income-and-asset question, which means Medicaid, and the right first call is your state Medicaid agency or SHIP, not Medicare.
- Is money tight, and the Medicare premium itself is the strain? Ask about Medicare Savings Programs before assuming your parent needs to qualify for full Medicaid.
- Still not sure who said what on the phone yesterday? A SHIP counsellor is free, and untangling exactly this is what the job is.
Where navigation fits into this picture
Since January 2024, Medicare Part B has carried its own billing codes for navigation: Community Health Integration (G0019, G0022) and Principal Illness Navigation (G0023, G0024). Navigate Care's navigators work under those Part B benefits. So this is a Medicare story, not a Medicaid one.
Medicare doesn't automatically cover navigation. Eligibility depends on a qualifying condition or need and a provider visit, the same as any other Part B service. For many patients with supplemental coverage the cost is usually $0, and we confirm your cost before you start; the introductory call is free either way. A navigator doesn't treat, diagnose or give medical advice, and doesn't replace a SHIP counsellor or an elder law attorney on a Medicaid question. What a navigator does is the follow-through: booking the referral, chasing the equipment, tracking what happens after a discharge. If you're trying to work out whether that's the right kind of help, or something else is, our compare page lays out the categories.
Here is how we help, in practice. Navigate Care matches your parent with one dedicated navigator, who coordinates appointments, referrals, medical equipment, benefits and support at home, by phone and video, in every US state. You tell us what is stuck. The navigator follows through, so you're not the one on hold.
To reach us, call 628 234 2273 (NAV-234-CARE). Tell us what is going on with your parent, and we'll talk through whether navigation fits. Eligibility depends on a qualifying condition or need and a provider visit, and we confirm your cost before you start. If your question is really about Medicaid, we'll point you to SHIP or your state Medicaid agency.
Frequently asked questions
Can you have Medicare and Medicaid at the same time?
Yes. People in this position are called dual eligible, or dually enrolled, and in 2026 about 12 million people nationally fall into that group. Medicare generally pays first on a shared bill, and Medicaid covers some or all of what's left, depending on the service and the state.
Does Medicaid pay for nursing home care that Medicare doesn't?
It can, for people who meet the state's income and asset limits, which is a separate and stricter test than ordinary Medicaid eligibility. Medicare's own nursing facility coverage is short-term and tied to a hospital stay. Long-term, ongoing care in a facility is generally where Medicaid, not Medicare, is the programme that pays, and getting there usually means planning well ahead of a placement, not applying the week it starts.
Is Medicaid only for low-income families with children, or can an older parent qualify?
Older adults and people with disabilities are among the groups every state has to cover in some form, alongside children, pregnant people and parents of dependent children. Many states cover additional groups too. Eligibility still comes down to income and assets, set by the state, so the honest answer for any one parent is to contact the state Medicaid agency directly.
If my parent is already on Medicare, do they need to apply for Medicaid separately?
Yes. Being on Medicare doesn't enrol anyone in Medicaid automatically. If your parent's income and assets fall under the state's limits, applying for Medicaid, or for a Medicare Savings Program if income is a little higher, is a separate step through the state Medicaid agency.
Does a Medicare navigator help with a Medicaid application or the look-back rules?
No. A navigator works under Medicare Part B's navigation benefits and doesn't give legal or financial advice. For a Medicaid application, the look-back period, or questions about gifting and asset transfers, the right first calls are a SHIP counsellor, who is free, your state Medicaid agency, or an elder law attorney.
What's the practical difference day to day, if my parent has only Medicare?
Mostly cost and what's covered outside the hospital. Medicare carries a monthly premium, a deductible, and usually 20% coinsurance on covered services, with the 2026 amounts detailed in our guide to Medicare Part B. It pays well for medical care and poorly for ongoing custodial help at home or in a facility. That second gap is exactly where Medicaid, for those who qualify, and family caregiving, for everyone else, tend to fill in. Our piece on what a caregiver actually does covers that second part.
