Medicaid vs Medicare for Low-Income Adults in 2026: Key Differences and How to Get Both
Millions of Americans mix up Medicaid and Medicare — the names sound alike, but they are two very different programs. If you are a low-income adult trying to get health coverage in 2026, knowing which one fits your situation (and whether you can have both) can save you money and stress. This guide breaks down the differences in plain language and shows you how to apply for each.
Medicaid vs Medicare: The Quick Answer
| Medicaid | Medicare | |
|---|---|---|
| Who runs it | Joint federal + state program | Federal program |
| Who it is for | People with limited income and resources | People 65+, or under 65 with certain disabilities |
| Main qualifier | Income (and household size) | Age or disability status — not income |
| Typical cost to you | Little or no cost in most cases | Monthly premiums, deductibles, and copays |
| How you apply | Anytime, through your state or the Marketplace | Through Social Security, usually around age 65 |
In short: Medicaid is income-based, Medicare is age/disability-based. Some people qualify for both.
What Medicaid Covers (and Who It Is For)
Medicaid is a joint federal and state program that provides free or low-cost health coverage to people with limited income and resources. Because states run their own Medicaid programs within federal rules, exact income limits and covered services vary by state. In the 40 states plus Washington, D.C. that adopted Medicaid expansion, adults ages 19–64 with income up to 138% of the federal poverty level can generally qualify based on income alone.
Medicaid usually covers hospital and doctor visits, lab work, prescriptions, maternity care, and more — often with little or no out-of-pocket cost. For a full breakdown of who qualifies and how the income tests work, see our guide to Medicaid eligibility in 2026.
What Medicare Covers (and Who It Is For)
Medicare is a federal health insurance program mainly for people age 65 and older. You can also qualify before 65 if you have received Social Security Disability Insurance (SSDI) for 24 months, or if you have End-Stage Renal Disease (ESRD) or ALS. Unlike Medicaid, Medicare eligibility is not based on your income.
Medicare has several parts: Part A (hospital), Part B (doctor/outpatient), Part C (Medicare Advantage), and Part D (prescription drugs). Most people get premium-free Part A if they or a spouse paid Medicare taxes long enough, but Part B and Part D usually have monthly premiums, and there are deductibles and copays. For the details, see our explainer on Medicare Parts A, B, C, and D and our guide to Medicare costs and help paying premiums.
