Medicare vs. Medicaid: What Is the Difference?

Medicare is federal health insurance mainly for people age 65 and older, plus some younger people with certain disabilities or conditions. Medicaid is a joint federal and state program that provides health coverage to certain low-income people, families, children, pregnant women, older adults, and people with disabilities. They are separate programs with different eligibility rules, costs, and application paths, and some people qualify for both.

The names sound alike, but a Medicare card does not mean Medicaid coverage, and a Medicaid card does not mean Medicare coverage. The distinction matters when you are comparing doctors, paying premiums, or applying for help with long-term care.

Medicare and Medicaid at a glance

What Medicare covers

• Part A (hospital insurance): inpatient hospital care, skilled nursing facility care, hospice care, and some home health care.
• Part B (medical insurance): services from doctors and other providers, outpatient care, home health care, durable medical equipment, and many preventive services.
• Part D (drug coverage): prescription drugs, offered through private plans that follow Medicare rules.
• Part C (Medicare Advantage): an alternative way to receive Part A and Part B benefits through a Medicare-approved private plan, usually including drug coverage.
• Medigap: supplemental insurance sold by private companies that helps pay some remaining costs under Original Medicare.

Original Medicare generally involves cost sharing such as a Part B premium, a deductible, and coinsurance. Medicare Advantage plans can have different networks, prior authorization rules, and out-of-pocket limits. Our guide to plan networks explains why the network rules matter.

What Medicaid covers

Medicaid programs must cover certain mandatory services and may cover additional optional ones. Coverage commonly includes doctor visits, hospital care, laboratory services, and preventive care, and Medicaid plays a large role in long-term services and supports such as nursing facility care and home health services. The exact benefit package and any cost sharing depend on the state and the eligibility group.

Can you have both?

Yes. Some people qualify for Medicare and Medicaid at the same time. Medicaid may then help pay Medicare premiums, deductibles, or coinsurance, and may cover services that Medicare does not. The rules and the name of the assistance program vary by state.

If you have Medicare and limited income and resources, ask your state Medicaid agency whether you qualify for help with Medicare costs, and confirm which program pays which bill before receiving care.

Long-term care and nursing homes

This is one of the most common points of confusion. Medicare generally covers short-term skilled nursing care after a qualifying hospital stay, not indefinite custodial care. Medicaid is the larger payer for long-term nursing facility and home-based care for people who meet its eligibility rules, including income and asset limits that vary by state.

Planning for long-term care is not a decision to make from a comparison table alone. Consult the state Medicaid agency and a qualified elder-law or benefits professional before restructuring finances or transferring assets.

How to apply

1. For Medicare: Check your situation on Medicare.gov. Some people are enrolled automatically through Social Security benefits; others must sign up. Review the enrollment periods that apply to you, especially if you are still working and have employer coverage.
2. For Medicaid: Start with your state Medicaid agency or the HealthCare.gov application, which can route your information to the state program. You can apply at any time of year.
3. If you may qualify for both: Apply for both and tell each program about the other coverage. Ask how the state coordinates benefits for people with Medicare and Medicaid.

Common mistakes

• Assuming Medicare covers all long-term custodial care.
• Assuming Medicaid is the same in every state.
• Missing a Medicare enrollment deadline because you are waiting for a Medicaid decision.
• Dropping employer coverage without checking how Medicare coordinates with it.
• Paying for a private "benefits finder" when official agencies provide eligibility screening for free.
• Assuming a Medicare Advantage plan is Medicaid because both involve private insurers.
