Medicaid and Medicare sound almost identical — and that’s where most of the confusion starts. They’re both government health insurance programs, both start with “Medi,” and both are frequently mentioned in the same breath. But they’re completely different programs.
Key Takeaways
- Medicare = federal health insurance primarily for people 65+ (and some younger with disabilities)
- Medicaid = joint federal-state program for people with low income, all ages
- Medicare is funded by payroll taxes; Medicaid is income-based
- You can qualify for both at the same time (“dual eligibility”)
- Medicare has premiums, deductibles, and copays; Medicaid is typically low- or no-cost
The Simple One-Line Difference
Medicare = age-based (primarily for people 65+)
Medicaid = income-based (for people with low income, regardless of age)
What Is Medicare?
Medicare is federal health insurance. You’re automatically eligible at 65, regardless of income. You’ve been paying into it your entire working life through payroll taxes.
Medicare’s Four Parts
Part A — Hospital Insurance
Covers inpatient hospital stays, skilled nursing facility care, hospice, some home health care.
- Premium: $0 for most people (if you worked 10+ years)
- Deductible: $1,632 per benefit period (2024)
Part B — Medical Insurance
Covers outpatient care, doctor visits, preventive services, medical equipment.
- Premium: ~$174.70/month (2024 standard)
- Annual deductible: $240
Part C — Medicare Advantage
Private insurance plans combining A + B (often + D) into one. Often includes vision, dental, and prescriptions.
Part D — Prescription Drug Coverage
Helps pay for prescriptions. Sold by private insurers.
- Premium: Typically $20–$60/month
What Is Medicaid?
Medicaid is a joint federal-state health insurance program for people with limited income and resources. No age requirement. Each state runs its own program within federal guidelines.
Who Qualifies?
Based on income, family size, and sometimes assets. The ACA expanded Medicaid to cover adults with incomes up to 138% of the Federal Poverty Level in most states.
Groups typically covered:
- Low-income adults (in expansion states)
- Children
- Pregnant women
- People with disabilities
- Low-income elderly (who may also have Medicare)
What Does Medicaid Cover?
- Doctor visits, hospital care
- Long-term nursing home care — major distinction from Medicare
- Mental health services, prescriptions
- Dental and vision (more commonly than Medicare)
How Much Does It Cost?
Usually free or very low cost. No monthly premiums for most enrollees. Copayments often $1–$8.
Side-by-Side Comparison
| Medicare | Medicaid | |
|---|---|---|
| Who it’s for | Primarily 65+, some with disabilities | Low-income people, all ages |
| How you qualify | Age or disability | Income and resources |
| Who runs it | Federal government | Federal + state |
| Cost to enrollee | Premiums, deductibles, copays | Usually free/very low |
| Long-term care | Limited (100 days max) | Yes, extensive |
| Income-based | No | Yes |
The Critical Difference: Long-Term Care
Medicare covers skilled nursing care only for up to 100 days after a hospital stay. After that, you’re on your own.
Medicaid is the primary payer for long-term nursing home care in the US. The average nursing home costs $80,000–$100,000/year. Medicare won’t cover it long-term. Medicaid will — but you generally must spend down most of your assets first.
Dual Eligibility: Having Both
Some people qualify for both programs at the same time — 65+ with low income. Medicaid then acts as secondary coverage, helping pay Medicare premiums, deductibles, and copays. About 12 million Americans are dual-eligible.
Common Misconceptions
“Medicare is free.” Part A usually is, but Part B costs ~$175/month and most people add Part D.
“Medicare covers nursing home care.” Only short-term skilled care after a hospital stay. Long-term care is Medicaid territory.
“I’ll never need Medicaid — I have Medicare.” They serve different functions. Even middle-class people may eventually need Medicaid for long-term care after exhausting savings.
The Bottom Line
- Medicare = health insurance you earned through work, primarily for 65+
- Medicaid = health insurance for low-income people, any age
Understanding the difference affects your retirement planning, long-term care planning, and how you navigate the healthcare system as you age.
