difference between medicaid and medicare
Medicare and Medicaid are both government health insurance programs in the United States, but they serve different groups of people and work in different ways.
What each program is
- Medicare is a federal health insurance program mainly for people aged 65 and older, and for some younger people with certain disabilities or conditions like end-stage renal disease or ALS, regardless of income.
- Medicaid is a joint federal and state program that provides health coverage for people with low income, including children, pregnant people, adults, seniors, and people with disabilities.
Who runs and funds them
- Medicare is run entirely by the federal government and is the same in every state.
- Medicaid is funded by both federal and state governments, but each state sets its own rules for eligibility and benefits within federal guidelines, so coverage details and income limits vary by state.
Eligibility basics
- Medicare :
- Age 65+ (most U.S. citizens or permanent residents with enough work history qualify).
- Under 65 with certain disabilities after a qualifying period, or with specific conditions like ESRD or ALS.
- Medicaid:
- Based primarily on income and, in some cases, assets, with thresholds set by each state.
- Many states that expanded Medicaid under the Affordable Care Act cover most adults under a certain income level.
What they cover
- Medicare is divided into parts:
* Part A: hospital insurance (inpatient stays, skilled nursing facility, some home health, hospice).
* Part B: medical insurance (doctor visits, outpatient care, preventive services).
* Part D: prescription drug coverage.
* Part C (Medicare Advantage): private plans that bundle Parts A and B, usually Part D, and may offer extra benefits.
- Medicaid generally covers:
- Hospital and doctor visits, emergency care, and preventive services.
- Many states also cover long-term services and supports like nursing home care and in-home care, which Medicare usually only covers short-term and under specific conditions.
Costs to you
- Medicare usually involves more out-of-pocket costs:
* Part A can have deductibles for hospital stays.
* Part B has a monthly premium, annual deductible, and 20% coinsurance for many services after the deductible.
* Part D and Medicare Advantage plans have their own premiums, copays, and cost-sharing.
- Medicaid often has low or no premiums and very small copays, depending on the state and the person’s income level.
Can someone have both?
- Some people qualify for both Medicare and Medicaid, often called “dual eligible.”
- In these cases, Medicare is usually the primary payer, and Medicaid may help cover premiums, deductibles, and services Medicare does not fully cover, such as some long-term care.
