What Is the Difference Between Medicare And Medicaid for the Elderly?

As you age, healthcare becomes a more important part of your life. However, navigating the healthcare system can be confusing, especially when it comes to understanding Medicare and Medicaid. 

In this guide, we’ll provide you with an overview of Medicare and Medicaid, including eligibility requirements, coverage and benefits, costs and expenses, enrollment and renewal, dual eligibility, and how to make informed decisions when choosing the right coverage.

What Is the Difference Between Medicare And Medicaid for the Elderly?

Medicare and Medicaid are two government-sponsored healthcare programs designed to provide health coverage for eligible individuals. However, there are some important differences between the two programs.

Medicare is a health insurance program administered by the federal government, primarily for individuals over 65 years of age or those with specific disabilities. Medicaid, on the other hand, is a state-run health insurance program for individuals and families with limited financial resources.

Both of these differ in terms of eligibility, coverage and benefits, costs and expenses, and other elements. We’ll break down those differences in the next section to help you decide which program is right for your needs.

1. Eligibility Requirements: Who Qualifies for Medicare and Medicaid

Medicare and Medicaid are two different government-sponsored healthcare programs with specific eligibility requirements.

Medicare is available to all U.S. citizens or legal residents who are 65 years of age and over, or who have certain disabilities. To qualify for Medicare, individuals must meet the following requirements: 

  1. be 65 or older, 
  2. have worked at least 10 years in a job covered by Social Security taxes, and 
  3. be a U.S citizen or legal resident for at least five continuous years.

Medicaid, on the other hand, is available to individuals and families who have limited financial resources. To qualify for Medicaid coverage, applicants must meet specific income and asset limits that vary by state. In general, those earning up to 138% of the Federal Poverty Level (FPL) may qualify for Medicaid coverage.

2. Coverage and Benefits: What Each Program Offers

The coverage and benefits provided by Medicare and Medicaid differ significantly. 

Medicare is divided into several parts, each offering different benefits. 

Part A of Medicare covers inpatient hospital stays, hospice care, and home health care. Part B covers doctor’s visits, preventive services, and outpatient care. Part C (also known as Medicare Advantage) is an alternative to original Medicare and is offered by private insurance companies. Part C plans provide all the benefits of Part A and Part B and may also offer additional benefits such as dental, vision, and hearing. Finally, Part D of Medicare covers prescription drugs.

Medicaid covers a wide range of healthcare services, including doctor’s visits, hospital care, nursing home care, home health care, and some prescription drugs. Medicaid also covers services that are not covered by Medicare, such as long-term care in a nursing home. Additionally, Medicaid may provide coverage for transportation to medical appointments, case management services, and in-home support services.

3. Costs and Expenses: Understanding Out-of-Pocket Expenses

Understanding the costs and expenses associated with each program is an essential part of making informed decisions about healthcare coverage. Medicare and Medicaid differ in terms of premiums, deductibles, and co-payments.

With Medicare, individuals are responsible for deductibles and copayments.  Deductibles are the amount of money that is paid before Medicare begins to pay for covered services. Copayments (or coinsurance) are the percentage of costs that an individual is responsible for paying out-of-pocket after meeting the deductible.

With Medicaid, however, out-of-pocket costs depend on the individual’s state of residence and income level. In most states, those with limited income are not required to pay premiums or copayments, but they may have to pay a small fee when they receive services such as doctor’s visits or prescription drugs.

4. Enrollment and Renewal: How to Enroll and Renew Your Coverage

Enrolling in Medicare is automatic for people who are 65 or older and receiving Social Security benefits. If you are not receiving Social Security benefits, you can enroll in Medicare by contacting the Social Security Administration. 

Enrolling in Medicaid varies by state, but you can typically apply online, by mail, or in person, at a local office. You will need to provide proof of income, residency, and citizenship or legal status.

To renew your Medicare coverage, you will need to review your plan annually and make changes during the open enrollment period, which runs from October 15 to December 7 each year. You can make changes to your Medicare Advantage or Medicare prescription drug coverage during this period.

To renew your Medicaid coverage, you will need to reapply each year and provide updated information about your income, residency, and citizenship or legal status. Your state Medicaid agency will send you a notice when it’s time to renew your coverage.

5. Coordinating Medicare and Medicaid: Dual Eligibility

If you’re eligible for both Medicare and Medicaid, you’re considered dual eligible. In this case, Medicare will typically be your primary insurance, and Medicaid will provide additional coverage and help cover costs that Medicare doesn’t. 

It’s important to know how your state coordinates Medicare and Medicaid benefits, as these rules can vary by state. You may be able to get help with premiums, copayments, deductibles, and other out-of-pocket costs. Additionally, you may have access to additional services that aren’t covered by Medicare or Medicaid separately.

6. Choosing the Right Coverage: Making Informed Decisions

Choosing the right coverage can be overwhelming, but there are resources available to help you make informed decisions. The Medicare website offers a wealth of information about coverage options, costs, and enrollment, and you can also speak with a licensed insurance agent for additional guidance. 

If you’re considering Medicaid, you can contact your state’s Medicaid office for more information. It’s important to take the time to research your options and compare plans to ensure that you’re getting the coverage you need at a price you can afford.


Choosing the right healthcare coverage is essential for seniors to maintain their health and well-being. Medicare and Medicaid are two programs that offer healthcare coverage to seniors, but they have different eligibility requirements, coverage and benefits, costs and expenses, and enrollment and renewal processes. By understanding these differences and making informed decisions, seniors can choose the right healthcare coverage to meet their needs and budget.
