Medicare vs Medicaid vs. Advantage Plans: The Basics

If you’ve ever tried to sort out health coverage for yourself or a loved one, you’ve probably run into these three names and wondered how they’re different. They sound similar, they’re all run through the government in some way, and we hear the terms Part A, B C and D. Here are some basics.

Medicare: Coverage Based on Age (or Disability in a small percentage of cases).

Medicare is a federal program, which means the rules are the same no matter what state you live in. You generally qualify at age 65, though people under 65 with certain disabilities or conditions can qualify earlier.

Medicare is broken into parts:

Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health care. Most people don’t pay a premium for Part A because they paid Medicare taxes while working.

Part B (Medical Insurance): Covers doctor visits, outpatient care, preventive services, and durable medical equipment. This one does come with a monthly premium — $202.90 for most people in 2026 — plus an annual deductible of $283.

Part D (Prescription Drug Coverage): Optional drug coverage through private plans approved by Medicare.

Together, Parts A and B are often called “Original Medicare.” After you hit the Part B deductible, Original Medicare typically covers 80% of approved outpatient costs, leaving you responsible for the other 20% — with no cap. That uncapped 20% is why many people also buy a Medigap (supplemental) policy or enroll in a Medicare Advantage plan instead.

Bottom line: Medicare is about age, not income.

Medicaid: Coverage Based on Income

Medicaid is a joint federal and state program that provides coverage to people with limited income and resources. Because states administer their own Medicaid programs within federal guidelines, eligibility rules, covered services, and even the program’s name can vary by state.

Medicaid can cover things Medicare doesn’t, such as long-term nursing home care and personal care services, which is why many low-income seniors qualify for both Medicare and Medicaid at the same time. When someone has both, they’re often called “dual eligible,” and Medicaid typically picks up costs that Medicare doesn’t cover, including premiums, deductibles, and copays.

Bottom line: Medicaid is about income and financial need, not age.

Medicare Advantage (Part C): A Private Alternative

Medicare Advantage plans are offered by private insurance companies approved by Medicare, as an alternative way to get your Medicare benefits. Instead of using Original Medicare, you enroll in a plan (often an HMO or PPO) that’s required to cover everything Original Medicare covers — and usually more, like dental, vision, hearing, or gym memberships. Most Advantage plans also bundle in Part D drug coverage.

A few key differences from Original Medicare:

Networks matter. You’ll often need to use doctors and hospitals within the plan’s network, similar to employer-based insurance.

Costs are structured differently. Instead of the uncapped 20% coinsurance under Original Medicare, Advantage plans use copays and coinsurance with an annual out-of-pocket maximum, which caps your worst-case costs for the year.

No Part B deductible. You won’t pay the $283 Part B deductible on an Advantage plan, though you will have the plan’s own cost-sharing structure.

Extra benefits, extra tradeoffs. The added perks can be attractive, but plan availability, networks, and costs vary widely by zip code and insurer.

Bottom line: Medicare Advantage is a private-plan way to receive your Medicare benefits, not a separate program from Medicare itself. It comes with more limited options that you’d expect from an “advantage plan,” fewer provider options, and sometimes more steps to get certain care approved.

Which One Applies to You?

It’s entirely possible to be connected to more than one of these at once. Someone can be on Medicare because of their age, qualify for Medicaid because of limited income, and choose to receive their Medicare benefits through a private Medicare Advantage plan. Understanding which lever each program pulls — age, income, or delivery method — makes the rest much easier to untangle.

If you’re approaching 65, losing employer coverage, or helping a family member sort out their options, it’s worth talking to a licensed insurance agent or using Medicare.gov‘s plan comparison tool to see what’s available in your specific area, since costs and plan choices vary by location.
