Why the Confusion?
Medicaid and Medicare are two of the largest government health insurance programs in the United States, and their similar names cause frequent confusion. While both are funded in part by the federal government and provide health coverage to millions of Americans, they serve fundamentally different populations and operate under very different rules.
At a Glance: Medicaid vs. Medicare
| Feature | Medicaid | Medicare |
|---|---|---|
| Who It Serves | Low-income individuals and families | People 65+ and certain disabled individuals |
| Basis of Eligibility | Income and financial need | Age or qualifying disability |
| Federal/State Role | Joint federal-state program; varies by state | Entirely federal program; uniform nationally |
| Cost to Beneficiary | Generally low or no cost | Premiums, deductibles, and copays apply |
| Long-Term Care | Yes, covers nursing home and home care | Limited; covers short-term skilled nursing only |
What Is Medicaid?
Medicaid is a joint federal and state program that provides health coverage to eligible low-income individuals, including children, pregnant women, adults, seniors, and people with disabilities. Because states administer the program within federal guidelines, eligibility rules, covered services, and program names vary significantly from state to state.
Under the Affordable Care Act (ACA), states had the option to expand Medicaid eligibility to cover nearly all adults under 65 with incomes up to 138% of the federal poverty level. Most states have adopted this expansion, but some have not — which can affect your eligibility depending on where you live.
What Medicaid Covers
- Doctor visits and hospital stays
- Prescription drugs
- Mental health and substance use treatment
- Long-term care in nursing facilities
- Home and community-based care
- Dental and vision services (varies by state)
What Is Medicare?
Medicare is a federal health insurance program primarily for people aged 65 and older, as well as younger people with certain disabilities or End-Stage Renal Disease. It is not income-based — eligibility is determined by age and work history (most people qualify based on their own or a spouse's payroll tax contributions).
Medicare's Four Parts
- Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services. Most people don't pay a premium for Part A.
- Part B (Medical Insurance): Covers doctor visits, outpatient care, preventive services, and some home health services. Requires a monthly premium.
- Part C (Medicare Advantage): An alternative way to receive Parts A and B through a private insurer, often with added benefits like dental and vision.
- Part D (Prescription Drug Coverage): Helps cover the cost of prescription medications. Offered through private insurers and requires a premium.
Can You Have Both? Dual Eligibility
Yes — people who qualify for both Medicaid and Medicare are called "dual eligible" beneficiaries. This typically applies to low-income seniors and certain low-income people with disabilities. For dual eligible individuals, Medicare generally pays first, and Medicaid covers remaining costs such as premiums, deductibles, and services not covered by Medicare.
How to Apply
- Medicaid: Apply through your state's Medicaid agency, through Healthcare.gov, or via your local social services office. Eligibility is reviewed annually.
- Medicare: If you receive Social Security benefits, you are generally enrolled automatically at age 65. Otherwise, you can enroll during your Initial Enrollment Period through Social Security (ssa.gov) or the Social Security Administration office.
Understanding which program you're eligible for — or whether you qualify for both — is an important step in accessing the healthcare coverage you're entitled to.
