What’s the Difference Between Medicare and Medicaid? What You Need to Know

Medicare and Medicaid are both essential programs in the U.S. healthcare system, but despite their similar-sounding names, they serve very different purposes. Understanding the difference between the two can help you make smarter decisions about your healthcare, your finances, and the options available to you.

Whether you're planning for retirement, supporting a loved one with a disability, or navigating life on a limited income, it's important to know which program applies to your situation and what benefits you may be entitled to. Let’s break it down together, so you can feel more confident in your choices and discover how Unified Health can help you access the care you deserve.

What Is Medicare?

Medicare is a federal program designed primarily for individuals who are 65 or older. It's also available to some younger individuals with qualifying disabilities or specific health conditions such as End-Stage Renal Disease (ESRD) or ALS. If you've received Social Security Disability Insurance (SSDI) for at least 24 months, you're likely eligible as well.

The program is structured into different parts, each covering a different aspect of care:

• Part A covers hospital-related services, including inpatient stays and skilled nursing facility care.

• Part B handles outpatient services like doctor visits, preventive screenings, and medical equipment.

• Part C, known as Medicare Advantage, is offered by private insurers and bundles Parts A and B, often with additional benefits like vision, dental, or wellness programs.

• Part D helps cover prescription drug costs.

Enrollment is generally straightforward, but it’s important to understand the timelines. Most people become eligible at age 65, and if you're already receiving Social Security benefits, enrollment in Parts A and B happens automatically. If not, you'll need to sign up during your initial enrollment period, which begins three months before your 65th birthday.

What Is Medicaid?

Medicaid is a joint federal and state program designed to provide health insurance to individuals and families with limited income and resources. It was created to ensure that low-income populations, including children, pregnant women, seniors, and people with disabilities, can access the healthcare they need.

Eligibility for Medicaid depends on several factors:

• Income and household size

• Age and disability status

• State-specific guidelines, since each state administers its own program

Unlike Medicare, which is the same nationwide, Medicaid programs vary significantly by state, meaning benefits, income limits, and application processes differ depending on where you live.

Covered Services May Include:

• Inpatient and outpatient hospital services

• Preventive care

• Mental health and substance use disorder services

• Prescription drugs

• Long-term care services like nursing home or in-home care

• Dental and vision (in some states)

• Transportation to medical appointments

Some states also offer Medicaid waivers for expanded services, including care for individuals who prefer to receive long-term care at home or in a community setting rather than a facility.

Key Differences Between Medicare and Medicaid

The most important distinction between these two programs lies in who they serve and how they’re funded and managed. Let’s break that down more clearly.

Eligibility:

• Medicare is primarily for individuals aged 65+ or younger people with qualifying disabilities or conditions like ESRD or ALS.

• Medicaid is based on financial need, and eligibility depends on income, assets, household size, and state-specific guidelines.

Cost & Financing:

• Medicare is funded by the federal government through payroll taxes and monthly premiums. Enrollees typically pay for their coverage through a combination of premiums, deductibles, and coinsurance.

• Medicaid is jointly funded by the federal government and individual states. It often has little to no cost for enrollees, and some states even provide full coverage without premiums or copays.

Coverage:

• Medicare focuses on hospital stays, doctor visits, and outpatient care, plus prescription drug coverage if you enroll in Part D.

• Medicaid provides more expansive coverage in many cases, including long-term care, home health aides, nursing facilities, dental care, and vision, depending on the state.

Administration:

• Medicare is a federally administered program, so the rules and benefits are consistent nationwide.

• Medicaid is state-administered, allowing for localized control and tailored benefits but leading to differences from one state to another.

Dual Eligibility: Can You Have Both Medicare and Medicaid?

Yes, many individuals qualify for both Medicare and Medicaid. These individuals are considered dually eligible, and they often experience the greatest benefits in terms of reduced healthcare costs and expanded coverage.

Dual eligibility typically applies to people over 65 or with disabilities who also meet their state’s income and asset criteria for Medicaid. In these cases, Medicare acts as the primary insurer, while Medicaid serves as the secondary payer, covering costs that Medicare doesn’t, such as premiums, coinsurance, or long-term care.

Being dual eligible may also qualify you for a Special Needs Plan (SNP) under Medicare Advantage, which is designed to better coordinate care across both programs. While navigating dual eligibility can seem confusing, it often results in the most comprehensive and affordable coverage available.

Costs of Medicare vs Medicaid

Medicare Costs (2025 Estimates):

• Part A: Free for most, but $1,632 deductible per benefit period if you’ve worked fewer than 40 quarters.

• Part B: $174.70 monthly premium (or more, depending on income), plus 20% coinsurance after deductible.

• Part D: Varies by plan; average premium is around $34/month, plus drug-specific copays.

• Medicare Advantage (Part C): Varies—some plans have $0 premiums but may include network restrictions or added copays.

Medicaid Costs:

• Typically low or no monthly premiums

• Minimal copays, if any, depending on income and state regulations

• Long-term care services, which Medicare doesn’t fully cover, are often included in Medicaid benefits, making it a lifeline for seniors or disabled individuals needing regular care

Understanding Medicare Advantage vs Medicaid Managed Care

As both Medicare and Medicaid evolve, many states and insurers have adopted managed care models to streamline services and control costs.

Medicare Advantage (Part C) plans are offered by private insurance companies and include all benefits under Medicare Parts A and B, with many plans also including Part D. These plans often include extra perks like dental, vision, and wellness services, and they typically use a provider network, meaning you must see doctors within the plan for the lowest costs.

Medicaid Managed Care works similarly but within the Medicaid system. States contract with private health plans to deliver services, manage costs, and coordinate care more effectively. These plans often include transportation to appointments, case management, and sometimes expanded dental or vision coverage, depending on the state.

Both types of managed care are designed to simplify the patient experience and offer more comprehensive benefits, but they are structured around different populations and eligibility criteria.

What to Do If You’re Eligible for Both Medicare and Medicaid

If you qualify for both programs, you’ll want to enroll in each separately, through the Social Security Administration for Medicare, and through your state Medicaid office for Medicaid. Once enrolled in both, your healthcare costs may be significantly reduced, and your access to care expanded.

You may also benefit from enrolling in a Dual Eligible Special Needs Plan (D-SNP) through Medicare Advantage. These plans are specifically designed to manage benefits from both Medicare and Medicaid and provide coordinated care and additional support.

Navigating dual coverage can feel complicated, but that’s where Unified Health comes in. We can help you understand how the two programs work together and ensure you don’t miss out on key benefits.

Common Misconceptions About Medicare and Medicaid

Medicare Myths:

• “Medicare is only for people over 65.” Not true, people with certain disabilities or medical conditions may qualify earlier.

• “Medicare covers everything.” Medicare doesn’t cover long-term care, dental, or vision unless you choose a Medicare Advantage plan that includes them.

• “Once enrolled, I don’t need to think about it again.” Medicare plans and costs can change yearly; you should reassess during the Open Enrollment Period.

Medicaid Myths:

• “Medicaid is only for kids or pregnant women.” Medicaid serves a wide range of populations, including seniors, people with disabilities, and low-income adults.

• “You can’t qualify if you have any savings.” Many states have expanded Medicaid and adjusted asset tests. Also, certain assets may be excluded.

• “It only covers emergency services.” Medicaid covers preventive care, long-term services, mental health, and more—depending on the state.

Recap and Next Steps

Key Takeaways: Medicare and Medicaid are both vital, but distinct. Medicare is primarily age- or condition-based and often includes premiums and out-of-pocket costs. Medicaid is income-based, generally free or low-cost, and may cover additional services like long-term care. Some individuals qualify for both and can benefit from dual eligibility.

Next Steps:

• Determine whether you’re eligible for Medicare, Medicaid, or both.

• Compare coverage and cost options in your state.

• Reach out to Unified Health for expert guidance and personalized plan selection.
