Medicaid vs Medicare: The Real Differences, Explained for 2027

Updated October 2026 for the 2027 plan year

What is the difference between Medicaid and Medicare?

The biggest difference is who each program is built for. Medicare is based mainly on age or disability. Medicaid is based mainly on income.

Medicare is one national program with the same core rules in every state. The Centers for Medicare & Medicaid Services (CMS), a federal agency, runs it. Your work history matters too, because it decides whether you pay a premium for hospital coverage.

Medicaid is really 50-plus programs. Each state runs its own Medicaid program within federal rules, so the income limits, program name and covered extras change from state to state. A family that qualifies in one state may not qualify in the next.

The names in the Medicaid vs Medicare question are easy to mix up. A simple memory trick: Medicare is for people you care for as they age, and Medicaid is aid for people with limited income. It is a shortcut, not a rule, since some younger people get Medicare and many older adults get Medicaid help too.

Medicaid vs Medicare comparison table

This table puts Medicaid vs Medicare side by side on the points people ask about most. Costs are described as concepts only, because amounts change every year and Medicaid cost-sharing varies by state.

What is Medicare?

Medicare is the federal health insurance program for people 65 or older who meet citizenship or residency rules. People under 65 can get it earlier if they have a disability, ESRD or ALS, according to Medicare.gov. Income does not decide whether you get Medicare.

Medicare comes in parts, and each part covers different care:

• Part A (Hospital Insurance) covers inpatient hospital stays, skilled nursing facility care, hospice and some home health care.
• Part B (Medical Insurance) covers doctors, outpatient care, preventive services and medical equipment.
• Part C (Medicare Advantage) is a private plan that bundles Part A, Part B and usually Part D.
• Part D (drug coverage) is sold by private insurers and helps pay for prescriptions.

Medicare is paid for through two trust funds held by the U.S. Treasury. Payroll taxes from workers, employers and self-employed people fund Part A. Premiums from enrollees and funds authorized by Congress fund Part B and drug coverage (Medicare.gov).

What is Medicaid?

Medicaid is public health coverage for people with limited income. It covers lower-income adults and children, pregnant people, older adults and people with disabilities. States administer it under federal requirements, and states and the federal government share the cost (Medicaid.gov).

Because each state runs its own program, Medicaid often goes by a state name. Arizona calls it AHCCCS, California calls it Medi-Cal, Tennessee calls it TennCare and Massachusetts calls it MassHealth. The rules behind the name are what matter.

The most important state choice is Medicaid expansion. In the 41 states (including DC) that expanded, most adults ages 19 to 64 qualify with income up to 138% of the federal poverty level. In the 10 states that did not, many adults without children can’t get Medicaid at any income. Our Medicaid eligibility guide has the full state-by-state table and income limits.

Which costs more, Medicaid or Medicare?

On cost, Medicaid vs Medicare is not close for most people: Medicaid costs less out of pocket. Most Medicaid enrollees pay no premium and little or nothing when they get care. Medicare has premiums, deductibles and coinsurance that most enrollees pay themselves or cover with extra insurance.

With Medicare, Part A is premium-free for most people who paid Medicare taxes long enough while working. Most people pay a monthly premium for Part B. Original Medicare has no yearly out-of-pocket cap, which is why many people add a Medigap policy or choose a Medicare Advantage plan.

With Medicaid, federal rules keep costs low. Some states charge small copays, and a few charge premiums to some groups with higher income. People who qualify for both programs usually get help with Medicare costs, as the next section explains.

We don’t list dollar amounts here because they change every year. For current Medicare amounts, check Medicare.gov. For Medicaid costs, check your state program.

Can you have Medicaid and Medicare at the same time?

Yes. Medicaid vs Medicare is not always either-or: people who qualify for both are called dual eligibles. CMS reports that nearly 12.5 million people were enrolled in both programs during fiscal year 2025. About 72% had full Medicaid benefits, and 28% had partial benefits (CMS Medicare-Medicaid Coordination Office report).

When you have both, Medicare pays first for services it covers. Medicaid then helps with what Medicare leaves behind, such as premiums, deductibles and coinsurance. Full-benefit Medicaid can also cover care Medicare doesn’t, like long-term nursing home care.

Help for people with partial benefits

Medicare Savings Programs are run by state Medicaid offices. They can pay your Part B premium and, in some cases, your deductibles and coinsurance (Medicare Savings Programs).

Help with prescription costs

If you have full Medicaid, a Medicare Savings Program or Supplemental Security Income, you get Extra Help with Part D drug costs automatically (Medicare.gov).

Where does the ACA Marketplace fit?

The ACA health insurance marketplace is for people who don’t have Medicare and can’t get affordable job-based coverage. It sits between the two programs. If your income is too high for Medicaid and you are not yet on Medicare, a Marketplace plan is usually your main option.

How the three fit together for someone under 65:

Two rules keep these programs separate. If you qualify for Medicaid, you can’t get a premium tax credit. And once you have Medicare Part A or Part C, you no longer qualify for Marketplace savings (HealthCare.gov).

The 400% cliff is back for 2027 coverage. Above 400% of the poverty level, which is $63,840 for one person, there is no tax credit. See how 2027 subsidies work for the full income table.

What happens to Medicaid or a Marketplace plan when you turn 65?

When you turn 65, Medicare usually becomes your main coverage, and you should sign up during your Initial Enrollment Period. That window lasts 7 months. It starts 3 months before the month you turn 65 and ends 3 months after it (Medicare.gov).

If you have a Marketplace plan

Your Marketplace plan does not end automatically when Medicare starts. You have to end it yourself, and you can report your Medicare start date up to 3 months early so the plans don’t overlap. After you have Part A, your premium tax credit stops, so keeping the plan usually means paying full price.

Don’t delay Medicare to keep a Marketplace plan. If you miss your first chance to enroll, you may have to wait for the General Enrollment Period from January 1 to March 31. Late enrollment penalties for Part B and Part D are added to your premiums for as long as you have that coverage.

If you have Medicaid

Turning 65 doesn’t automatically end Medicaid. Your state will review whether you still qualify under its rules for older adults, which can include asset limits. If you qualify for both, you become a dual eligible and Medicare pays first.

If you’re still working at 65

If you have job-based coverage through an employer, the rules are different. You may be able to delay Part B without a penalty. Check with the employer’s plan and Social Security before deciding.

What is changing for Medicaid in 2027?

Federal law signed on July 4, 2025 (Public Law 119-21, often called H.R. 1) changes Medicaid in 2026 and 2027. Medicare is not changing in the same way. Three changes matter most for people comparing Medicaid vs Medicare this year.

• Work requirements. States must start requiring many expansion adults ages 19 to 64 to show 80 hours a month of work, school, a work program or community service by January 1, 2027. People enrolled in Medicare, pregnant people, parents of children 13 and under, and medically frail people are among those exempt (CMS).
• Six-month renewals. Most expansion adults will need to renew eligibility every 6 months, starting with renewals scheduled on or after January 1, 2027 (CMS State Medicaid Director Letter #26-001).
• Immigrant eligibility. Since October 1, 2026, federal Medicaid funding is generally limited to U.S. citizens and nationals, lawful permanent residents, Cuban/Haitian entrants and Compact of Free Association migrants. Emergency Medicaid continues (CMS).

If you lose Medicaid in 2027, you usually get a Special Enrollment Period to buy a Marketplace plan. Act fast, because the window is generally 60 days.
