Medicare and Medicaid sound almost identical, but they are two completely different programs. Medicare is federal health insurance based on age or disability. Medicaid is a joint federal-state program based on income. Understanding which program you qualify for, and whether you can receive both, is one of the most important healthcare decisions you will make.

What Is Medicare?
Medicare is a federal health insurance program primarily for Americans aged 65 and older. It was established in 1965 under the Social Security Act and is administered by the Centers for Medicare & Medicaid Services (CMS). Your eligibility is based on age or disability status, not your income.
Medicare is divided into four parts:
- Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care (up to 100 days), hospice care, and some home health services. Most people pay no premium for Part A if they or their spouse paid Medicare taxes for at least 10 years.
- Part B (Medical Insurance): Covers doctor visits, outpatient care, preventive services, medical equipment, and some home health services. The standard monthly premium is $202.90 in 2026.
- Part C (Medicare Advantage): Private insurance plans approved by Medicare that bundle Part A, Part B, and usually Part D. Many plans include extras like dental, vision, and hearing coverage.
- Part D (Prescription Drug Coverage): Covers prescription medications through private plans. Starting in 2025, a $2,000 annual out-of-pocket cap eliminates the coverage gap (donut hole).
Medicare does not cover everything. Notable gaps include routine dental care, most vision services, hearing aids, and long-term custodial care. That is why many beneficiaries add a Medicare Supplement (Medigap) plan to help cover out-of-pocket costs.
What Is Medicaid?
Medicaid is a joint federal and state health insurance program that provides coverage to people with limited income and resources. Unlike Medicare, Medicaid is administered by individual states under broad federal guidelines, which means eligibility rules, benefits, and costs vary significantly depending on where you live.
More than 78 million Americans currently receive Medicaid benefits. The program covers:
- Children and adolescents
- Pregnant women
- Low-income adults (in states that expanded Medicaid)
- Seniors with limited income
- People with disabilities
All state Medicaid programs must cover a set of mandatory benefits, including inpatient and outpatient hospital services, doctor visits, laboratory tests, home health services, and nursing facility care. Many states go further and offer optional benefits like prescription drugs, dental care, vision services, and physical therapy.
Medicaid Expansion Under the ACA
The Affordable Care Act (ACA) gave states the option to expand Medicaid to cover adults under 65 with incomes at or below 138% of the federal poverty level (FPL). As of 2026, 41 states plus Washington, D.C. have adopted Medicaid expansion.
In expansion states, a single adult earning approximately $20,783 or less per year may qualify. In non-expansion states, eligibility thresholds are often much lower, and many low-income adults without children may not qualify at all.
Key Differences Between Medicare and Medicaid
While both programs help Americans access healthcare, the difference between Medicare and Medicaid comes down to several core areas.
Eligibility: Age vs. Income
This is the fundamental distinction. Medicare eligibility is based primarily on age. When you turn 65, you qualify for Medicare regardless of your income or wealth. You may also qualify before 65 if you have received Social Security Disability Insurance (SSDI) for 24 months, have end-stage renal disease (ESRD), or have ALS (Lou Gehrig’s disease).
Medicaid eligibility is based on financial need. You must meet your state’s income limits, and in some states, asset limits as well. A billionaire turning 65 qualifies for Medicare. A 30-year-old earning below the poverty level may qualify for Medicaid.
Administration: Federal vs. State
Medicare is a federal program with consistent rules nationwide. Whether you live in Florida or Oregon, your Medicare Part A and Part B benefits are the same.
Medicaid is a partnership between federal and state governments. The federal government sets minimum standards, but each state designs its own program. This means Medicaid benefits, eligibility thresholds, and application processes can differ dramatically from one state to the next.
Coverage Differences
Medicare covers hospital care, doctor visits, preventive services, and prescription drugs through its four parts. However, Original Medicare (Parts A and B) does not cover dental, vision, hearing, or long-term custodial care.
Medicaid typically provides more comprehensive coverage, particularly for:
- Long-term care: Medicaid is the primary payer for nursing home care in the United States. Medicare only covers up to 100 days of skilled nursing following a hospital stay.
- Dental and vision: Most state Medicaid programs cover routine dental and vision care, which Original Medicare does not.
- Transportation: Many Medicaid programs cover non-emergency medical transportation to appointments.
Costs: Premiums, Deductibles, and Out-of-Pocket
Medicare has real out-of-pocket costs. In 2026, the standard Part B premium is $202.90 per month. Part A has a $1,736 deductible per benefit period. Part B has a $283 annual deductible, plus 20% coinsurance on most services. These costs are why many beneficiaries add Medigap supplemental insurance or choose a Medicare Advantage plan. For a complete breakdown, see our Medicare costs guide.
Medicaid is designed for people with limited financial resources, so out-of-pocket costs are minimal. Most beneficiaries pay no premiums. Copays, when required, are typically $1 to $4. Total household out-of-pocket costs are capped at 5% of income.
Enrollment Timing
Medicare has specific enrollment periods. Your Initial Enrollment Period (IEP) is the 7-month window around your 65th birthday. Miss it, and you may face late enrollment penalties. There is also an Annual Enrollment Period (October 15 through December 7) and an Open Enrollment Period (January 1 through March 31). Learn more in our guide to applying for Medicare.
Medicaid has no enrollment periods. You can apply any time throughout the year by contacting your state Medicaid agency or visiting HealthCare.gov.
Dual Eligibility: Can You Have Both Medicare and Medicaid?
Yes. Approximately 12.8 million Americans, known as “dual eligibles,” qualify for both Medicare and Medicaid simultaneously. This typically includes seniors aged 65 and older who also have very low incomes.
If you qualify for both programs:
- Medicare pays first for covered services like hospital stays and doctor visits
- Medicaid pays second, covering Medicare premiums, deductibles, copays, and services that Medicare does not cover (like long-term care, dental, and vision)
- You may qualify for Medicare Savings Programs (MSPs) that help pay Medicare Part B premiums and cost-sharing
- You automatically qualify for Extra Help (Low-Income Subsidy) with Part D prescription drug costs
Dual-eligible beneficiaries also have access to special Dual Eligible Special Needs Plans (D-SNPs), which are Medicare Advantage plans specifically designed to coordinate Medicare and Medicaid benefits under one plan.
Medicare Savings Programs for Low-Income Beneficiaries
Even if you do not fully qualify for Medicaid, you may be eligible for a Medicare Savings Program that helps reduce your Medicare costs:
| Program | Income Limit (2026, individual) | What It Covers |
|---|---|---|
| Qualified Medicare Beneficiary (QMB) | Up to 100% FPL (~$15,060/year) | Part A & B premiums, deductibles, coinsurance, copays |
| Specified Low-Income Medicare Beneficiary (SLMB) | 100-120% FPL (~$18,072/year) | Part B premiums only |
| Qualifying Individual (QI) | 120-135% FPL (~$20,331/year) | Part B premiums only |
| Qualified Disabled and Working Individuals (QDWI) | Up to 200% FPL (~$30,120/year) | Part A premiums only |
State-by-State Medicaid Variations
Because Medicaid is administered at the state level, your benefits and eligibility can vary significantly depending on where you live. Here are some key differences to be aware of:
- Income thresholds: Expansion states cover adults up to 138% FPL. Non-expansion states like Texas, Florida, and Georgia have much lower income limits, sometimes covering only parents with incomes below 50% FPL.
- Benefits: While all states must cover mandatory services, optional benefits like dental, vision, physical therapy, and prescription drugs vary. Some states offer robust dental coverage; others provide only emergency dental services.
- Asset limits: Some states consider assets (savings, investments) in addition to income when determining eligibility. Others have eliminated asset tests for certain groups.
- Program names: Many states operate Medicaid under different names. For example, California’s program is called Medi-Cal, Tennessee’s is TennCare, and Massachusetts operates MassHealth.
To check your state’s specific Medicaid eligibility rules, contact your state Medicaid office or visit HealthCare.gov.
How Medicare Supplement Insurance Fits In
If you have Medicare but do not qualify for Medicaid, a Medicare Supplement (Medigap) plan can help fill the gaps in Original Medicare coverage. Medigap plans are sold by private insurance companies and help pay for costs like:
- Part A and Part B deductibles
- Coinsurance and copayments
- Excess charges above Medicare-approved amounts
- Foreign travel emergency care (on some plans)
Popular Medigap options include Plan G and Plan N, which offer strong coverage at reasonable premiums. If you are turning 65, your Medigap Open Enrollment Period is the best time to enroll, as insurers cannot deny you coverage or charge higher premiums based on health conditions during this window.
Important note: You cannot have both a Medigap plan and Medicaid. If you qualify for Medicaid, it typically covers the gaps that Medigap would, making a supplemental plan unnecessary.
Common Misconceptions About Medicare and Medicaid
These programs are frequently misunderstood. Here are the most common misconceptions Karl Bruns-Kyler, founder of The Big 65 with over 20 years of Medicare expertise, encounters when helping clients:
Misconception 1: “Medicare and Medicaid are the same program”
They are not. Medicare is federal insurance based on age. Medicaid is a federal-state assistance program based on income. They were created by the same legislation in 1965 but operate independently.
Misconception 2: “Medicare covers long-term nursing home care”
Medicare only covers up to 100 days of skilled nursing facility care after a qualifying hospital stay. For long-term custodial care, including extended nursing home residence, Medicaid is the primary payer. This is one of the most critical planning considerations for retirees.
Misconception 3: “You have to choose one or the other”
Not true. If you meet the eligibility requirements for both, you can and should enroll in both. Dual coverage provides the most comprehensive benefits available.
Misconception 4: “Medicaid is only for young people or children”
While Medicaid covers millions of children and families, it is also a critical program for seniors. Medicaid pays for more than 60% of all nursing home residents in the United States.
Misconception 5: “If I have Medicare, I don’t need to worry about Medicaid”
Even with Medicare, significant out-of-pocket costs remain. If your income is limited, Medicaid or Medicare Savings Programs can help cover premiums, deductibles, and services that Medicare does not cover, like dental and long-term care.
How to Determine Which Program Is Right for You
Figuring out whether you qualify for Medicare, Medicaid, or both depends on your age, income, disability status, and state of residence.
You Likely Qualify for Medicare If:
- You are 65 years old or older
- You or your spouse paid Medicare taxes for at least 10 years (40 quarters)
- You are under 65 and have received SSDI benefits for 24 months
- You have been diagnosed with ESRD or ALS
You May Qualify for Medicaid If:
- Your income is below your state’s Medicaid threshold
- You are pregnant, a parent of dependent children, or have a disability
- You are a senior with very limited income and assets
- You live in a Medicaid expansion state and earn below 138% FPL
You May Qualify for Both If:
- You are 65+ with income below your state’s Medicaid limits
- You are a Medicare beneficiary with a disability and limited income
