Medicare and Medicaid sound alike — and many Americans confuse them. But they are two very different government health programs with different eligibility rules, costs, and coverage. Understanding the difference matters: choosing the wrong program, or missing out on one you qualify for, can cost you thousands of dollars in medical bills every year.
This guide explains Medicare vs Medicaid in plain English: what each program covers, who qualifies, what it costs in 2026, how the two programs work together, and how to figure out which one applies to you.
Medicare vs Medicaid at a Glance
The simplest way to remember the difference:
- Medicare is based mainly on age and disability. You qualify when you turn 65 (or after 24 months on Social Security Disability Insurance), regardless of income.
- Medicaid is based mainly on income. You qualify if your income and assets are below your state's limits, at any age.
Medicare is a federal program administered the same way in every state. Medicaid is a joint federal-state program, so eligibility rules, covered services, and even the program's name vary by state.
Here is a side-by-side comparison:
- Run by: Medicare — federal government. Medicaid — federal + state governments.
- Based on: Medicare — age (65+) or disability. Medicaid — income and assets.
- Age requirement: Medicare — 65+ (or disability). Medicaid — any age.
- Income requirement: Medicare — none. Medicaid — must be below state limits.
- Premiums: Medicare — yes (Part B, Part D, Advantage plans). Medicaid — usually $0 or very low.
- Coverage: Medicare — hospital, medical, drugs (with Part D). Medicaid — broad, including long-term care.
- Can you have both? Yes — about 12 million Americans are "dual-eligible."
What Is Medicare?
Medicare is federal health insurance for people age 65 and older, and for younger people with certain disabilities or end-stage renal disease (ESRD). You pay into Medicare through payroll taxes during your working years, and you become eligible at 65.
Medicare has four parts:
- Part A (Hospital Insurance): Inpatient hospital stays, skilled nursing facility care, hospice, and some home health care. Most people pay no premium for Part A because they paid Medicare taxes while working.
- Part B (Medical Insurance): Doctor visits, outpatient care, preventive services, lab tests, durable medical equipment. In 2026, the standard Part B premium is $185 per month (higher earners pay more through IRMAA surcharges).
- Part C (Medicare Advantage): An all-in-one alternative to Original Medicare (Parts A + B) offered by private insurers. Often includes drug coverage plus dental, vision, hearing, and fitness benefits. Many plans charge $0 additional premium.
- Part D (Prescription Drug Coverage): Standalone drug plans that cover medications. Average premium is around $40–$50 per month in 2026.
Most people enroll in Medicare during their Initial Enrollment Period — the seven months around their 65th birthday. If you delay enrollment without other qualifying coverage, you may face permanent late-enrollment penalties.
What Is Medicaid?
Medicaid is a joint federal-state program that provides free or low-cost health coverage to people with limited income and resources. It covers children, pregnant women, parents, adults, seniors, and people with disabilities who meet income requirements.
Because each state runs its own Medicaid program (within federal guidelines), the details differ:
- Eligibility: In states that expanded Medicaid under the Affordable Care Act (ACA), most adults earning up to 138% of the Federal Poverty Level (FPL) qualify. In non-expansion states, eligibility is narrower — often limited to children, pregnant women, parents with very low income, and people with disabilities.
- Program names: Many states brand Medicaid differently — Medi-Cal (California), MassHealth (Massachusetts), TennCare (Tennessee), BadgerCare (Wisconsin), Apple Health (Washington).
- Covered services: Federal law requires states to cover hospital services, doctor visits, lab tests, X-rays, nursing facility care, home health care, and children's services. States may add dental, vision, prescription drugs, and more.
- Costs: Most Medicaid enrollees pay no premiums and little or no copays. Some states charge small copays ($1–$8) for certain services.
You can apply for Medicaid at any time of year through your state's Medicaid agency or HealthCare.gov. Unlike Medicare, there is no age requirement — a newborn and a 90-year-old can both qualify if their income is low enough.
Key Differences: Medicare vs Medicaid
1. Who Qualifies
Medicare: You qualify at 65 if you (or your spouse) paid Medicare taxes for at least 10 years (40 quarters). You also qualify if you have been receiving Social Security Disability Insurance (SSDI) for 24 months, or if you have ESRD or ALS (Lou Gehrig's disease).
Medicaid: You qualify based on income and household size. In expansion states, adults earning up to 138% of FPL (about $21,800 per year for an individual in 2026) qualify. Children qualify at higher income levels — up to 200–300% of FPL in many states through Medicaid and CHIP (Children's Health Insurance Program).
2. What It Costs
Medicare: Part A is usually free. Part B costs $185/month (2026). Part D adds $40–$50/month. If you add a Medigap supplement, expect another $100–$300/month. Total annual Medicare costs for a typical retiree: $3,000–$7,000 in premiums, deductibles, and copays.
Medicaid: Usually free. Most enrollees pay no premiums, no deductibles, and minimal copays. Medicaid is designed to be affordable for people with very limited income.
3. What It Covers
Medicare: Covers hospital care, doctor visits, preventive services, and (with Part D) prescription drugs. It does not cover most dental, vision, hearing, or long-term custodial care.
Medicaid: Covers a broader range of services, including long-term care (nursing homes, home health aides), dental and vision in many states, and transportation to medical appointments. Medicaid is the largest payer of long-term care in the United States.
4. Provider Networks
Medicare (Original): You can see any doctor or hospital that accepts Medicare — no network restrictions. Medicare Advantage plans use networks (HMO/PPO).
Medicaid: You must use providers who accept Medicaid. Not all doctors accept Medicaid because reimbursement rates are lower than Medicare or private insurance. Provider availability varies by state and region.
5. Prescription Drug Coverage
Medicare: Drug coverage comes through Part D plans or Medicare Advantage plans with drug coverage (MAPD). You pay premiums, deductibles, and copays.
Medicaid: Prescription drugs are covered with little or no copay in most states.
Can You Have Both Medicare and Medicaid?
Yes. People who qualify for both are called "dual-eligible" beneficiaries. This typically happens when someone is 65 or older (or disabled) and has very low income.
If you are dual-eligible:
- Medicare pays first for services it covers. Medicaid pays second, covering costs Medicare does not — including premiums, deductibles, and copays.
- Medicaid may cover services Medicare does not, such as long-term care, dental, and vision.
- You automatically qualify for Extra Help (Low-Income Subsidy) for prescription drugs — worth about $5,000 per year.
- You may be eligible for a Dual-Eligible Special Needs Plan (D-SNP), a type of Medicare Advantage plan designed specifically for dual-eligibles, with extra benefits and care coordination.
If you think you may be dual-eligible, apply for Medicaid through your state agency even if you already have Medicare. Many seniors miss out on Medicaid because they assume Medicare is their only option.
Medicare Savings Programs (MSPs)
Even if your income is too high for full Medicaid, you may qualify for a Medicare Savings Program — a state program that pays your Medicare premiums and sometimes deductibles and copays. There are four levels:
- Qualified Medicare Beneficiary (QMB): Pays Part A and B premiums, deductibles, coinsurance, and copays. Income limit: up to 100% of FPL.
- Specified Low-Income Medicare Beneficiary (SLMB): Pays Part B premiums only. Income limit: 100–120% of FPL.
- Qualifying Individual (QI): Pays Part B premiums only. Income limit: 120–135% of FPL. Funded on a first-come, first-served basis.
- Qualified Disabled and Working Individuals (QDWI): Pays Part A premiums for certain disabled people who returned to work. Income limit: up to 200% of FPL.
MSP asset limits vary by state, and several states have eliminated asset tests entirely. If your income is modest, it is worth applying — many people who qualify never apply because they do not know these programs exist.
Medicaid Eligibility in 2026: Income Limits
Medicaid income limits depend on your state, household size, and category. Approximate guidelines for 2026:
- Expansion-state adults: Up to 138% of FPL — about $21,800 (individual) or $37,800 (family of three).
- Children (Medicaid/CHIP): Up to 200–300% of FPL in most states — about $52,000–$78,000 for a family of three.
- Pregnant women: Up to 200%+ of FPL in most states.
- Seniors / disabled (Aged, Blind, and Disabled Medicaid): Typically up to 100% of FPL, with asset limits around $2,000 (individual) / $3,000 (couple) — though limits vary by state.
- Medically needy (spend-down): In some states, people with high medical bills can "spend down" to Medicaid eligibility by subtracting medical expenses from their income.
To check your state's exact limits, visit your state Medicaid website or HealthCare.gov. Income is usually calculated using Modified Adjusted Gross Income (MAGI) for most adult and child categories.
Long-Term Care: Where Medicaid Matters Most
One of the biggest differences between Medicare and Medicaid is long-term care. Medicare covers short-term skilled nursing care after a hospital stay (up to 100 days, with copays after day 20). It does not cover long-term custodial care — help with bathing, dressing, eating, and other daily activities.
Medicaid is the primary payer of long-term care in the United States, covering more than 60% of nursing home residents. If you need long-term care and have limited assets, Medicaid may cover nursing home costs, assisted living (in some states), and home- and community-based services.
Because nursing home care averages $9,000–$11,000 per month, many middle-class families eventually rely on Medicaid for long-term care after spending down their savings. Estate planning attorneys often help families navigate Medicaid's five-year "look-back" period for asset transfers.
How to Apply
Medicare: Apply at SSA.gov or call Social Security at 1-800-772-1213. Enroll during your Initial Enrollment Period (the 7 months around your 65th birthday) to avoid penalties. If you are already receiving Social Security benefits, you will be enrolled automatically.
Medicaid: Apply through your state Medicaid agency or HealthCare.gov. You can apply any time of year. You will need proof of income, residency, citizenship or immigration status, and household size.
Both: If you are 65+ and low-income, apply for both. Start with Medicare (you may face penalties if you delay), then apply for Medicaid and Medicare Savings Programs to help with costs.
Common Mistakes to Avoid
- Assuming Medicare is free. Part B, Part D, and Medigap premiums add up to thousands per year.
- Assuming Medicaid is only for children. Adults, seniors, and people with disabilities can all qualify.
- Missing the Medicare enrollment window. Late-enrollment penalties are permanent and increase your premiums for life.
- Not applying for Medicaid because you think you earn too much. Income limits vary by state and category — children, pregnant women, and medically needy applicants have higher limits.
- Confusing Medicare Advantage with Medicaid managed care. Both use private insurers, but they are different programs with different rules.
- Not checking for dual eligibility. If you have both Medicare and low income, Medicaid can pay your premiums and out-of-pocket costs.
- Forgetting Extra Help. Dual-eligibles and low-income Medicare beneficiaries qualify for Extra Help with drug costs — apply through Social Security.
Medicare vs Medicaid: Which One Do You Need?
- You are 65+: Medicare. Apply for Medicaid too if your income is low.
- You are under 65 with low income: Medicaid (or ACA marketplace coverage with subsidies).
- You are disabled and receiving SSDI for 24 months: Medicare. Apply for Medicaid too if your income is low.
- You are low-income and need long-term care: Medicaid is the primary payer.
- You have children and low income: Medicaid/CHIP for your children, even if you do not qualify yourself.
- You are a senior with modest income: Medicare + Medicare Savings Program + possibly Medicaid.
The Bottom Line
Medicare and Medicaid serve different people, but they overlap for millions of Americans who need both. Medicare covers you when you turn 65 or become disabled. Medicaid covers you when your income is low — at any age — and fills gaps Medicare leaves, especially long-term care.
If you are 65 or older, enroll in Medicare on time. If your income is limited, apply for Medicaid and Medicare Savings Programs — they can pay your premiums, reduce your out-of-pocket costs, and cover services Medicare does not. And if you qualify for both, you have some of the most comprehensive coverage available in the American health system.
