Differences Between Medicare and Medicaid
Find out the differences between Medicare and Medicaid before you need them.

Many people are confused about Medicare and Medicaid. Even those eligible for one or both get them mixed up. This short article explains the programs. Hopefully, readers will understand the differences and will benefit from them when they become eligible.
Medicare and Medicaid
Both Medicare and Medicaid are government programs. However, they have different characteristics and requirements. Some people are eligible for only one, while others might be eligible for both. What they have in common is that they are both health-related services.

Medicare: Definition
Medicare is a federal health insurance for anyone age 65 and older, and some people under 65 with certain disabilities or conditions.
Medicare Eligibility Requirements
- For the original Medicare Parts A and B eligibility:
- Age 65 or older
- Younger than 65 with a qualifying disability
- Living with end-stage kidney disease
Medicare Coverages
Usually, Medicare is a person's primary plan and covers most Medicare-eligible healthcare services. There are four different parts of Medicare for specific services.
- Medicare Part A usually helps cover hospital or long-term care costs.
- Medicare Part B covers certain doctors’ services, outpatient care, medical supplies, and preventive services.
- Medicare Part C is a Medicare Advantage plan that provides all of Part A and Part B coverage and typically offers extra benefits such as vision, hearing, and dental care. Most also include Medicare Part D drug coverage.
- Medicare Part D helps cover the cost of prescription drugs.

Medicaid: Definition
Medicaid is a joint federal and state program that gives health coverage to some people with limited income and resources.
Medicaid Eligibility Requirements
Medicaid is often the secondary plan and may cover medical costs that Medicare doesn't cover or only partially covers.
Every state has its own rules for Medicaid, but the common ones include:
- Age 65 and older
- A child under age 19
- Pregnant
- Living with a disability
- A parent or adult caring for a child
- An adult with dependent children
- An eligible immigrant
Dual Eligibility
Some people are qualified for both Medicare and Medicaid, but they may not know how to apply for both. About 12 million Americans qualify for benefits from both programs. Therefore, they are “dual eligible,” and the coverage is called "dual eligibility."
A person must sign up for Medicare Part A and Part B through Social Security to make both retirement and Medicare choices and withhold any premiums from their benefit payments.
To apply for Medicaid, people should contact their State Medicaid Agency. Services covered by dual eligibility include:
- Medical equipment, such as crutches, canes, walkers, and wheelchairs
- Doctor visits
- Inpatient and outpatient hospital services
- Mental health services
- Prescription drugs
- Preventive care
- Dental services
- Vision care

Thank you, Margaret for this summary. I am pretty well-versed in both Medicare and Medicaid (Medi-Cal) as I take care of my 88 year-old mom who is in advanced stages of dementia, she’s completely blind, she is unable to walk and has dual eligibility. So of course me being me I’ve done a whole lot of research on both insurances. But it’s nice to see a summary like this which just lays everything out plain and simple and easy to understand. Because there is a lot of confusion about these types of plants. So I thank you for this public service.
Great summary 👌 👏 helpful
