What’s the Difference Between Medicare and Medicaid?

Medicare vs. Medicaid at a Glance

When comparing Medicare and Medicaid, understanding their foundational differences is crucial, especially as the landscape shifts in 2026. Here’s a streamlined overview to quickly grasp the key distinctions:

Feature	Medicare	Medicaid
Administered by	Federal government	Federal and state governments
Primary eligibility	Age 65+, disabilities (24 months SSDI), ESRD, ALS	Low income (≤138% FPL in expansion states), assets, family size/status
Coverage focus	Hospital (Part A), outpatient (Part B), drugs (Part D), limited long-term	Comprehensive: long-term care, dental, vision, transportation
Costs	Premiums (e.g., Part B), deductibles, 20% coinsurance	Low/no cost; covers Medicare gaps for dual eligibles
2026 updates	Consistent rules; Part D deductible up to $590	Higher long-term care income caps; state-by-state changes

Who Qualifies?

Medicare Eligibility (2026)

• Age 65+: U.S. citizens or permanent residents (5+ years). Most are automatically enrolled if already on Social Security, while others enroll during their Initial Enrollment Period (IEP): 3 months before to 3 months after their 65th birthday month. For detail on eligibility groups, see Who Does Medicare Help? Eligibility and Beneficiary Groups.
• Under 65: Qualify after 24 months on Social Security or Railroad Retirement disability benefits, or with certain medical conditions like End-Stage Renal Disease (ESRD) and ALS.
• No income or asset test. Medicare eligibility is national and does not vary by state.

Medicaid Eligibility (2026)

• Income-based: Uses Modified Adjusted Gross Income (MAGI) compared to the Federal Poverty Level. In expansion states, adults under 65 are eligible at ≤138% FPL (due to a 5% income disregard, this covers most up to 133% FPL).
• Long-term care: New 2026 cap: $2,982/month for single applicants, $5,964 for couples. Applicants must also meet asset tests & demonstrate medical necessity (e.g., require nursing home level care).
• Dual eligible standards: For programs like the Qualified Medicare Beneficiary (QMB), income is limited to ~100% FPL (+$20 disregard), assets to $9,950 individual, $15,000 couple.
• Eligibility varies by state, household size, pregnancy, disability status. Several states add requirements, such as work (usually up to 80 hours/month).

To check for your state’s requirements, use a Medicaid eligibility checker from your state’s health department or marketplace.

What Do They Cover?

Medicare Coverage

• Part A: Inpatient hospital stays, skilled nursing facilities, some home health, hospice care. Part A is usually premium-free if you or your spouse paid payroll taxes for at least 10 years. Learn more in What’s the Difference Between Medicare A and B?.
• Part B: Outpatient services, doctor visits, preventive care (patients pay 20% coinsurance after the deductible).
• Part C (Medicare Advantage): Plans offered by private insurers, combining Part A and B (and often Part D), with extra features like dental, vision, and gym memberships, plus an annual out-of-pocket maximum.
• Part D: Prescription drugs (requires separate premium, deductible up to $590 for 2026).
• What’s not covered: Most long-term care, dental, vision, and hearing (except via Medicare Advantage plans).

Medicaid Coverage

• Core benefits: Hospital and outpatient care, doctor visits, prescription drugs, mental health services.
• Additional benefits: Long-term nursing home and home care, dental, vision, personal care, transportation to medical appointments, physical/occupational therapy, and more.
• Coverage scope and additional services may vary by state. Medicaid is especially important for long-term care, which Medicare mostly does not cover (Does Medicare Pay Family Caregivers in 2025?).

State Medicaid programs typically fill in gaps not covered by Medicare, particularly for dual eligibles. Medicare covers acute and preventive care first; Medicaid often covers long-term services, extra benefits, and help with cost-sharing.

Costs and Out-of-Pocket Expenses

• Medicare – 2026 Cost Projections:
  • Part A usually has no monthly premium for most but has a deductible and coinsurance for hospital stays.
  • Part B premium expected to be around $174.70/month (based on prior year), deductible and 20% coinsurance on outpatient/doctor costs. These costs are standardized nationwide.
  • Part D (drug coverage) has a separate premium; deductible up to $590 in 2026.
  • Medicare Advantage (Part C) often has additional monthly premiums but caps out-of-pocket expenses, which Original Medicare does not. Costs and coverage for these plans could differ by location and insurer.
• Medicaid: Usually no premium; co-pays are minimal or waived, especially for low-income enrollees and children. Medicaid covers most out-of-pocket expenses for those who qualify, including premiums, deductibles, and copays, especially for those dual eligible.
• Dual eligible: People in both programs rarely pay premiums, copays, or deductibles for covered services. Medicaid acts as a backup insurance, filling gaps and covering long-term care not handled by Medicare.

Dual Eligibility and How to Apply

Dual eligibles (those who qualify for both programs) receive the most comprehensive coverage with premium and out-of-pocket costs drastically reduced-including access to long-term care, home and community services, and extra medical/dental benefits. In 2026, about 10-12 million people are expected to qualify as dual eligibles.

• Medicare is always the primary payer: it covers services first, then Medicaid covers most remaining costs (including some services Medicare won’t cover).
• Key dual-eligible programs (like QMB, SLMB): Help pay Medicare Part A/Part B premiums, deductibles, and coinsurance.
• States like Massachusetts now require that you have both Medicare Parts A/B and MassHealth to be dual eligible for certain plans.

How to apply:

• Apply for Medicare through SSA.gov or by calling 1-800-MEDICARE. Most people are auto-enrolled (65+, already on Social Security).
• Apply for Medicaid through your state’s Department of Health or marketplace (for most adults, visit HealthCare.gov). Applications will assess income, assets, and medical needs.
• Applying for Medicaid when you have Medicare will trigger an automatic review for Medicare Savings Programs (QMB, SLMB, QI, QDWI), which can further reduce or eliminate your Part B premium and other costs.

Many states offer an interactive eligibility quiz online or in their Medicaid portals. Look for a “Check Your Eligibility” section for tailored responses based on your age, income, and health status.

Medicare vs. Private Insurance (Bonus Comparison)

With changes to the health insurance landscape and the role of the Affordable Care Act, it’s useful to understand the difference between Medicare and private insurance (such as individual ACA/Obamacare or employer coverage), especially for those transitioning from work to retirement:

Feature	Medicare	Private Insurance (e.g., ACA)
Eligibility	65+, or disabled	No employer coverage, any age; eligibility for subsidies based on income
Costs	Fixed premiums/deductibles (Parts A/B/D, Medigap, Advantage)	Premiums and deductibles vary widely; income-based subsidies can reduce cost significantly
Coverage	Standardized hospital and outpatient care-must add Part D, Medigap, or Advantage plans for drug/extra coverage	Wide variation in coverage, often includes preventive care, dependent on plan selection
Provider access	Broad, most doctors/hospitals nationwide accept	Typically more limited to specific networks

For those newly retiring or losing employer coverage, it’s important to understand whether Medicare coverage plus supplemental options might better suit your needs compared to keeping private insurance or COBRA plans.

FAQs

• Can I have both Medicare and Medicaid? Yes. If you’re dual eligible, you can receive coordinated coverage with Medicare serving as your primary insurance and Medicaid covering remaining costs or additional services.
• Is Medicaid free for seniors? In most cases, yes. Medicaid is designed to fill the coverage and cost-sharing gaps left by Medicare, and for low-income seniors, it largely eliminates premiums and out-of-pocket costs. Coverage varies by state.
• Which pays first-Medicare or Medicaid? Medicare is always the primary payer, while Medicaid steps in secondarily for qualifying enrollees.
• What’s new for 2026? Medicaid’s income limits for long-term care have increased. Certain states (such as Massachusetts) tightened dual-eligible requirements, like mandating enrollment in both Medicare Parts A/B. Some states may introduce or expand work requirements for certain adult enrollees.
• Is private insurance better than Medicare? It depends. Private insurance is typically best for working adults and those with employer coverage or ACA subsidies. For most people over 65 or with qualifying disabilities, Medicare paired with supplemental coverage often provides broader and more predictable benefits, especially for those with ongoing or complex health needs.
• How can I get help choosing the right coverage? For comparison shopping or questions about choosing supplement insurance, check the Wisconsin Medicare Supplemental Insurance Plans Guide and related resources.
