Medicare and Medicaid are both government-sponsored health insurance programs, but they are designed for different groups of people and follow different guidelines. Knowing the difference matters, particularly if you may be eligible for both.
Medicare Overview
Medicare is a federal program that mainly covers individuals aged 65 and older. It is managed by the Centers for Medicare & Medicaid Services (CMS) and offers uniform core benefits throughout the country.
Who is eligible:
- Adults who are 65 or older
- Individuals under 65 with qualifying disabilities who have collected Social Security Disability Insurance (SSDI) for 24 months
- Individuals diagnosed with End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS)
Notable characteristics:
- Eligibility depends primarily on age or disability status, not income
- Financed through payroll taxes, beneficiary premiums, and general federal revenue
- Enrollees generally pay premiums, deductibles, and coinsurance
Medicaid Overview
Medicaid is a combined federal and state program created for individuals with limited income and financial resources. Each state runs its own Medicaid program under federal guidelines, meaning benefits and eligibility thresholds differ from state to state.
Who is eligible:
- Low-income adults, children, pregnant women, seniors, and people with disabilities
- Income limits vary by state (many states broadened eligibility through the Affordable Care Act)
Notable characteristics:
- Eligibility is determined by income and household size
- Benefits differ by state but must include certain required services
- Most enrollees pay little to nothing out of pocket
Comparison at a Glance
| Feature | Medicare | Medicaid | |---|---|---| | Run by | Federal government | State governments (with federal oversight) | | Eligibility basis | Age or disability | Income and resources | | Premiums | Yes (Part B, Part D) | Minimal or none | | Cost sharing | Deductibles, coinsurance, copays | Very low or none | | Coverage scope | Standardized nationwide | Varies by state |
Dual Eligibility: Covered by Both Programs
Certain individuals qualify for Medicare and Medicaid at the same time. These people are referred to as "dual eligibles." When you have dual coverage, Medicaid can help cover your Medicare premiums, deductibles, and copays, which greatly lowers your out-of-pocket healthcare spending.
Programs available to dual eligibles include:
- Qualified Medicare Beneficiary (QMB) program
- Specified Low-Income Medicare Beneficiary (SLMB) program
- Qualifying Individual (QI) program
Determining the Right Program for You
If you are nearing 65, Medicare will likely be your primary source of health coverage. If your income is limited, you should also check whether you qualify for Medicaid in your state. Having both programs can give you comprehensive benefits while keeping your out-of-pocket costs to a minimum.
