If you’re navigating the world of government health insurance, you’ve probably heard the terms “Medicare” and “Medicaid” used interchangeably. While these programs sound similar and both provide health coverage to millions of Americans, they’re quite different. Understanding the distinction between Medicare and Medicaid is crucial, especially if you or a loved one may need to rely on these programs for healthcare coverage.
What is Medicare?

Medicare is a federal health insurance program primarily designed for people aged 65 and older. Think of it as a benefit you’ve earned through years of paying into the system through payroll taxes. Even if you’re still working at 65, you’re eligible for Medicare based on your age alone.

Beyond seniors, Medicare also covers certain younger individuals with disabilities who have received Social Security Disability Insurance (SSDI) benefits for at least 24 months, as well as people with End-Stage Renal Disease (ESRD) or ALS (Lou Gehrig’s disease), regardless of age.
The key point here is that Medicare is primarily age-based and isn’t dependent on your income level. Whether you’re a millionaire or living on a modest fixed income, if you’re 65 or older and have paid into the system, you qualify for Medicare.
The Four Parts of Medicare
Medicare is divided into four parts, each covering different healthcare services:
Part A (Hospital Insurance) covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health services. Most people don’t pay a premium for Part A because they or their spouse paid Medicare taxes while working.
Part B (Medical Insurance) covers doctor visits, outpatient care, preventive services, and medical equipment. Part B requires a monthly premium, which in 2024 is $185 for most people.
Part C (Medicare Advantage) is an alternative way to receive your Medicare benefits through private insurance companies approved by Medicare. These plans often include prescription drug coverage and may offer additional benefits like dental and vision care.
Part D (Prescription Drug Coverage) helps cover the cost of prescription medications. This is optional coverage provided through private insurance companies, with premiums varying by plan.
What is Medicaid?
Medicaid, on the other hand, is a joint federal and state program that provides health coverage to people with limited income and resources. Unlike Medicare, Medicaid is need-based. It’s designed as a safety net for individuals and families who cannot afford health insurance on their own.
Because Medicaid is run jointly by the federal government and individual states, eligibility requirements, covered services, and program names vary significantly from state to state. What Medicaid covers in California may differ from what it covers in Texas or New York.
Medicaid serves several groups: low-income adults, children, pregnant women, elderly adults, and people with disabilities. There’s no age requirement—you can qualify for Medicaid at any age if you meet your state’s income and resource requirements.
Key Differences Between Medicare and Medicaid
Eligibility Requirements
The most fundamental difference is who qualifies. Medicare eligibility is primarily based on age (65+) or disability status, regardless of income. You’ve essentially earned Medicare by paying into the system through payroll taxes during your working years.
Medicaid eligibility is based on financial need. Each state sets its own income limits, but generally, you must have limited income and assets to qualify. Some states have expanded Medicaid under the Affordable Care Act, raising income limits and covering more people.
How Medicaid Runs
Medicaid is a partnership between federal and state governments. While the federal government sets basic guidelines, each state administers its own program, sets eligibility standards within federal minimums, determines benefits packages, and sets payment rates for providers. This is why Medicaid can look very different depending on where you live.
Cost to Beneficiaries
With Medicare, most people pay premiums, deductibles, and copayments. Part B requires a monthly premium, and if you want prescription drug coverage (Part D) or a Medicare Advantage plan (Part C), you’ll pay additional premiums. There are also deductibles and coinsurance amounts you’re responsible for.
Medicaid, by contrast, has little to no cost for beneficiaries. Some states may charge small copayments for certain services, but these are minimal—often just a few dollars. Many services have no cost-sharing at all, recognizing that beneficiaries have limited financial resources.
What’s Covered
Both programs cover essential health services, but there are differences. Medicare covers medically necessary services and supplies but has notable gaps. Traditional Medicare doesn’t cover routine dental care, eye exams for glasses, or hearing aids. It also has limited coverage for long-term nursing home care.
Medicaid often provides more comprehensive coverage, including services Medicare doesn’t cover. Importantly, Medicaid is the primary payer for long-term care services, including nursing home care, which can be financially devastating without coverage. Many states also include dental, vision, and hearing services in their Medicaid programs.
Can You Have Both Medicare and Medicaid?
Yes, and this is actually quite common. People who qualify for both programs are called “dual eligibles.” If you’re 65 or older (qualifying you for Medicare) but also have limited income and resources (qualifying you for Medicaid), you can receive benefits from both programs.
When you have both, Medicare pays first, and Medicaid acts as secondary coverage, often paying Medicare premiums, deductibles, and copayments that you would otherwise owe. This combination provides comprehensive coverage with minimal out-of-pocket costs.
There are also Medicare Savings Programs for people whose income is too high for full Medicaid but still need help paying Medicare costs. These programs, administered by states, help pay Medicare premiums and sometimes deductibles and coinsurance.
Why the Confusion?
Given how different these programs are, why do people confuse them? Several factors contribute to the mix-up:
First, the names sound similar—both start with “Medi” and were created around the same time (1965). Second, both are government health insurance programs, which leads people to assume they work the same way. Third, the Centers for Medicare & Medicaid Services administers both programs at the federal level, creating an administrative connection. Finally, many people qualify for both programs simultaneously, further blurring the lines.
Which Program Might You Need?
If you’re turning 65, you’ll want to enroll in Medicare. You should sign up during your Initial Enrollment Period, which begins three months before your 65th birthday month and ends three months after. Missing this window can result in late enrollment penalties.
If you’re under 65 and struggling financially, or if you’re 65+ with limited income and resources, you may qualify for Medicaid. Contact your state’s Medicaid office to learn about eligibility requirements and how to apply. Every state has a different application process, and some states use different names for their programs.
If you have a disability and receive SSDI, you’ll qualify for Medicare after receiving benefits for 24 months. If you also have limited income and resources, you should apply for Medicaid as well to get comprehensive coverage.
The Bottom Line
While Medicare and Medicaid both provide vital health coverage, they serve different purposes and populations. Medicare is an earned benefit primarily for seniors and certain people with disabilities, funded through payroll taxes you paid during your working years. Medicaid is a safety net program for people with limited financial resources, regardless of age.
Understanding these differences helps you know which program you might qualify for and what coverage you can expect. Many people will interact with one or both of these programs at some point in their lives, whether for themselves or a family member. If you’re unsure which program applies to your situation, contact your local State Health Insurance Assistance Program (SHIP) for free, personalized counseling, or speak with a qualified elder law attorney who can help you navigate these complex systems and maximize your benefits.
Both programs represent America’s commitment to ensuring that seniors, people with disabilities, and those facing financial hardship have access to necessary healthcare. While navigating government programs can feel overwhelming, understanding the basics of Medicare and Medicaid is the first step toward securing the coverage you or your loved ones need.
