Medicare and Medicaid are two of the largest government health insurance programs in the United States, yet millions of Americans confuse the two. While both programs help people afford medical care, they serve different populations, cover different services, and operate under different rules.
Understanding which program you qualify for can save you thousands of dollars in medical expenses and ensure you get the coverage you need. This guide breaks down everything you need to know about Medicare vs Medicaid so you can make an informed decision about your health coverage.
What Is Medicare?
Medicare is a federal health insurance program primarily designed for Americans aged 65 and older. The program also covers certain younger individuals with disabilities and people with End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS).
Medicare is administered by the Centers for Medicare and Medicaid Services (CMS) and funded through payroll taxes, premiums paid by enrollees, and general federal revenue. Regardless of your income level, if you meet the age or disability requirements, you are eligible for Medicare.
The Four Parts of Medicare
Medicare is divided into four distinct parts, each covering different types of care:
Part A (Hospital Insurance) covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care. Most people do not pay a premium for Part A if they or their spouse paid Medicare taxes for at least 10 years (40 quarters). In 2026, the Part A deductible is approximately $1,632 per benefit period.
Part B (Medical Insurance) covers doctor visits, outpatient care, medical supplies, and preventive services. The standard Part B premium in 2026 is around $185 per month, though higher-income earners pay more through Income-Related Monthly Adjustment Amounts (IRMAA). Part B has an annual deductible of approximately $257.
Part C (Medicare Advantage) is offered by private insurance companies approved by Medicare. These plans bundle Part A and Part B coverage, and most include Part D prescription drug coverage. Many Medicare Advantage plans offer additional benefits like dental, vision, and hearing coverage. Learn more about choosing the right plan on our Medicare page.
Part D (Prescription Drug Coverage) helps cover the cost of prescription medications. Part D plans are offered by private insurers and vary in which drugs they cover (their formulary), the pharmacies you can use, and what you pay out of pocket.
What Is Medicaid?
Medicaid is a joint federal and state program that provides health coverage to low-income individuals and families. Unlike Medicare, Medicaid eligibility is based primarily on income and household size rather than age.
Each state administers its own Medicaid program under broad federal guidelines, which means eligibility requirements, covered services, and program names vary significantly from state to state. For example, California calls its program Medi-Cal, while Tennessee calls theirs TennCare.
Who Qualifies for Medicaid?
Medicaid eligibility varies by state, but under the Affordable Care Act, states that expanded Medicaid generally cover adults with household incomes up to 138% of the Federal Poverty Level (FPL). As of 2026, that threshold is approximately $20,783 per year for an individual or $43,056 for a family of four.
Groups commonly eligible for Medicaid include:
- Low-income adults (in states that expanded Medicaid)
- Pregnant women with incomes up to 138% FPL (many states set higher thresholds)
- Children in low-income families
- Individuals with disabilities
- Seniors with limited income and resources
- Parents and caretaker relatives meeting income requirements
States that did not expand Medicaid often have stricter eligibility rules, and some low-income adults in those states may fall into a coverage gap where they earn too much for traditional Medicaid but too little for marketplace subsidies.
Key Differences Between Medicare and Medicaid
Understanding the differences between these two programs is critical for choosing the right coverage. Here is a side-by-side comparison of the most important factors.
Eligibility
Medicare eligibility is based on age (65+), disability status, or specific medical conditions. Your income does not affect whether you qualify for Medicare, though it can affect your premiums.
Medicaid eligibility is based on income, household size, and sometimes additional factors like disability, pregnancy, or age. Requirements vary by state, and some states have more generous income limits than others.
Cost to Enrollees
Medicare requires enrollees to pay premiums (Part B and Part D), deductibles, copays, and coinsurance. Part A is premium-free for most people, but the other parts come with monthly costs. Many beneficiaries purchase supplemental Medigap policies to help cover out-of-pocket expenses.
Medicaid has little to no cost for enrollees. Most Medicaid beneficiaries pay no premiums and have minimal copays, typically $1 to $4 for services. Some states charge small premiums for certain Medicaid populations.
Coverage
Medicare covers hospital care, doctor visits, preventive services, and prescription drugs. Original Medicare (Parts A and B) does not cover dental, vision, or hearing services, though Medicare Advantage plans often include these benefits.
Medicaid provides comprehensive coverage that often exceeds what Medicare offers. Federal law requires Medicaid to cover hospital services, doctor visits, lab work, home health services, nursing facility care, and more. Many states also cover dental, vision, prescription drugs, and mental health services through their Medicaid programs.
Administration
Medicare is a federal program with uniform rules across all 50 states. Whether you live in New York or Nebraska, your Medicare benefits work the same way.
Medicaid is jointly funded by federal and state governments, but each state sets its own rules within federal guidelines. This means your coverage options, eligibility, and benefits depend heavily on where you live.
Can You Have Both Medicare and Medicaid?
Yes. People who qualify for both programs are known as "dual eligible" beneficiaries. Approximately 12 million Americans hold both Medicare and Medicaid coverage simultaneously.
How Dual Eligibility Works
If you are dual eligible, Medicare serves as your primary insurance and pays first for covered services. Medicaid then acts as secondary insurance, picking up costs that Medicare does not cover. This can include Medicare premiums, deductibles, copays, and services that Medicare does not cover like dental care and long-term care.
Who Qualifies as Dual Eligible?
You may qualify for dual coverage if you are 65 or older (or have a qualifying disability) and also meet your state's Medicaid income requirements. Common dual eligible scenarios include:
- Seniors with limited Social Security income
- Individuals with disabilities receiving Supplemental Security Income (SSI)
- People who need long-term nursing home care and have depleted their assets
Medicare Savings Programs
Even if you do not qualify for full Medicaid, you might be eligible for a Medicare Savings Program (MSP) that helps pay for Medicare premiums and cost-sharing. These programs include:
- Qualified Medicare Beneficiary (QMB): Pays Part A and Part B premiums, deductibles, and coinsurance
- Specified Low-Income Medicare Beneficiary (SLMB): Pays Part B premiums
- Qualifying Individual (QI): Pays Part B premiums on a first-come, first-served basis
- Qualified Disabled and Working Individuals (QDWI): Pays Part A premiums
How Medicaid Varies by State
Because Medicaid is a state-administered program, the differences from one state to the next can be dramatic.
Medicaid Expansion States
As of 2026, 40 states plus Washington, D.C., have expanded Medicaid under the Affordable Care Act. In expansion states, adults earning up to 138% of the FPL qualify for coverage. This expansion has provided coverage to millions of Americans who previously had no affordable insurance options.
Non-Expansion States
The remaining 10 states have not expanded Medicaid. In these states, childless adults often cannot qualify for Medicaid regardless of how low their income is. Parents may need to earn well below the poverty line to qualify. If you live in a non-expansion state and need affordable coverage, you may want to explore marketplace health insurance plans or other options through our comparison tools.
State-Specific Benefits
Beyond the federally required benefits, states can choose to cover additional services. Many states cover:
- Adult dental care (coverage ranges from emergency-only to comprehensive)
- Vision services and eyeglasses
- Chiropractic care
- Physical therapy beyond federal minimums
- Personal care services
- Non-emergency medical transportation
How to Apply for Medicare
Initial Enrollment
Most people are automatically enrolled in Medicare Part A when they turn 65 if they are already receiving Social Security benefits. If you are not receiving Social Security, you need to actively sign up during your Initial Enrollment Period (IEP), which begins three months before your 65th birthday and ends three months after.
Enrollment Methods
You can apply for Medicare in several ways:
- Online at ssa.gov
- By calling Social Security at 1-800-772-1213
- In person at your local Social Security office
Choosing Your Coverage
After enrolling in Original Medicare, you will need to decide whether to add Part D prescription drug coverage, purchase a Medigap supplemental policy, or switch to a Medicare Advantage plan. This is an important decision that affects your costs and coverage for the year ahead. Our team at QuickCare can help you compare Medicare options to find the best fit.
How to Apply for Medicaid
Checking Eligibility
The fastest way to check your Medicaid eligibility is through your state's Medicaid website or by visiting HealthCare.gov. You will need information about your household income, family size, and residency status.
Application Process
You can apply for Medicaid through:
- Your state Medicaid agency's website
- HealthCare.gov (in most states)
- By phone through your state's Medicaid hotline
- In person at a local Medicaid office or community health center
- By mail using a paper application
Unlike Medicare, Medicaid has no specific enrollment periods. You can apply at any time of year, and if you qualify, coverage can begin as early as the date of your application. Some states even provide retroactive coverage for up to three months before your application date.
Common Questions About Medicare and Medicaid
What if I turn 65 and still work?
If you have employer coverage when you turn 65, you may be able to delay Medicare enrollment without penalty, depending on your employer's size. If your employer has 20 or more employees, you can keep your employer plan as primary and enroll in Medicare later during a Special Enrollment Period.
Does Medicaid cover long-term care?
Yes. Medicaid is the largest payer of long-term care services in the United States, covering nursing home care and many home and community-based services. Medicare, by contrast, covers only short-term skilled nursing care (up to 100 days) following a qualifying hospital stay.
Can I use Medicaid in another state?
Medicaid coverage is state-specific. If you move to a new state, you will need to apply for Medicaid in that state. Emergency Medicaid services are available across state lines, but routine care generally requires in-state coverage.
What happens if my income changes?
If you are on Medicaid and your income increases above the eligibility threshold, you may lose coverage. However, you would likely qualify for a Special Enrollment Period on the health insurance marketplace to find a new plan. If you are on Medicare, income changes may affect your Part B and Part D premiums but will not affect your eligibility.
