Understanding the differences between Medicare vs. Medicaid

Find Senior Living Near You:

Since 1965, Medicare and Medicaid have been protecting the health and wellbeing of millions of Americans. Though the government programs have evolved over the years, they still provide seniors, people with disabilities, and low-income families access to affordable, quality health care.

If you're 65 or older, or nearing that age, familiarizing yourself with Medicare and Medicaid can help you determine if you're eligible and how these government programs can assist you in living a longer, more independent life. Here, we'll cover all the basics of Medicare and Medicaid, their differences, and how to know if you qualify for either (or both).

What Is the Difference Between Medicare and Medicaid?

With similar-sounding names, it's no wonder that Medicare and Medicaid get confused sometimes! Both are funded by taxpayers; what sets these two programs apart is who they provide health care coverage for.

Original Medicare is a federal health insurance program that provides health care coverage for Americans age 65 and older, as well as those who live with a disability.

Medicaid is a joint federal and state health insurance program that covers Americans with a limited income. Adults who are 65 or older and meet the limited-income requirements may be covered by both programs.

What Is Medicare?

Medicare

Medicare subsidizes health care costs for Americans 65 and older, and some people under 65 with certain disabilities or conditions. It's the primary health care insurance provider for seniors. While Medicare certainly helps reduce medical expenses, it doesn't fully cover everything. Let's look at the plans and benefits that make up Medicare!

Original Medicare consists of two parts:

  • Medicare Part A (hospital insurance)
  • Medicare Part B (medical insurance)

As mentioned earlier, Original Medicare covers some health care costs, not all. For example, there's no yearly limit on what you pay out of pocket with Original Medicare.

The good news is that enrollees have additional options to reduce wallet-busting out-of-pocket expenses. These programs allow individuals to add on or bundle their benefits through private insurance companies that contract with Medicare:

  • Medicare Part C (Medicare Advantage)
  • Medicare Part D (Prescription Drug Plan)
  • Medicare Supplement Insurance (Medigap)

We'll go into more detail about the different parts of Medicare later in this article.

To learn more about Medicare, watch the video below with our editor-in-chief, Jeff Hoyt.

Who Qualifies for Medicare?

To qualify for Medicare coverage, you must be a United States resident and either a U.S. citizen or a lawfully admitted alien who has lived in the U.S. for five continuous years. You also must meet at least one of the following criteria:1

  • You are age 65 or older.
  • You have been disabled for over 24 months.
  • You have been diagnosed with end-stage renal disease.
  • You have Lou Gehrig's disease (ALS).

Medicare Enrollment Options

Every day, nearly 10,000 Americans age into the Medicare program.2 There are certain times throughout the year when seniors can enroll in Medicare. We'll touch on the six options for enrollment below. Once you're enrolled in Medicare, you'll receive your red, white, and blue Medicare card in the mail, as well as a welcome packet.

  1. Initial enrollment period: You have a seven-month window around your 65th birthday to enroll in Medicare. It begins three months before your birthday month and ends three months after you turn 65. It is best to enroll during this time to avoid being charged late enrollment penalties.
  2. Annual enrollment period: Medicare's annual open enrollment is from Oct. 15 to Dec. 7. During this time, you can join, drop, or switch to another plan. This includes Medicare Advantage (Medicare Part C) and Medicare Part D Prescription Drug Plans.
  3. General enrollment period: If you miss your seven-month window, you can enroll during the general enrollment period, which is Jan. 1 to March 31 each year. If you enroll during this time, your coverage will begin July 1 of the same year. You may have to pay a higher Part A or Part B premium for missing the initial enrollment period.
  4. Special enrollment period: Individuals age 65 and older who are still in the workforce may be covered by their employer's group health plan (or their spouse's health plan). In this case, you can enroll anytime you're still covered by the group health or during the eight-month period after your coverage ends. The special enrollment period is applicable to seniors who are 65 and working but thinking about retirement.
  5. Medicare Advantage open enrollment period: If you're enrolled in a Medicare Advantage Plan, you can switch to a different Medicare Advantage Plan or switch to Original Medicare (and join a separate Medicare drug plan) once from Jan. 1 to March 31 each year.
  6. Medigap open enrollment period: Medigap's six-month open enrollment begins on the first day of the month in which you are 65 or older and have enrolled in Medicare Part B.

Pro Tip: Getting ready to enroll in Medicare for the first time or make changes to your current plan? Our in-depth Medicare enrollment guide covers everything you need to know about Medicare.

How to Enroll in Medicare

If you aren't yet receiving Social Security benefits but would like to enroll in Medicare, you can do so by creating a My Social Security account and applying through the Social Security Administration (SSA) benefits page.

FYI: If you're currently receiving Social Security benefits, you will automatically be enrolled in Medicare and should receive your Medicare card and welcome packet in the mail three months before your 65th birthday.

If you'd prefer to enroll by phone, you can call the SSA toll-free at 800-772-1213. If you have hearing loss, call the toll-free TTY number, 800-325-0778. Representatives are available from 7 a.m. to 7 p.m., Monday through Friday.

What You Don't Know About Medicare That Could Hurt You

Medicare is a complicated program; however, once you're equipped with the right information, you can enroll knowing you're getting the most out of your Medicare plan! Before you enroll, watch the video below with our Editor-in-Chief, Jeff Hoyt, as he covers topics you might not know about Medicare that could hurt you.

What Does Medicare Cover?

If you're unsure why we have Medicare Part A and Part B or wondering what the difference is between Medigap and Medicare Advantage, we have the answers! Read on to find out what each part of Medicare covers and what its main purpose is.

Medicare Part A

Medicare Part A, sometimes referred to as “hospital insurance,” covers hospital and hospice expenses. This includes inpatient care, hospice care, home health care, and short-term stays in a skilled nursing facility.

Adults age 65 and over are eligible for premium-free Medicare Part A at no cost if3:

  • You are already receiving retirement benefits from Social Security or the Railroad Retirement Board.
  • You are eligible to receive Social Security or Railroad benefits but haven't filed for them yet.
  • You or your spouse had Medicare-covered government employment.

Hospital expenses covered by Medicare Part A4:

  • Semiprivate rooms
  • General nursing
  • Meals
  • Drugs needed during inpatient treatment
  • Other hospital services and supplies as part of your inpatient treatment

Did You Know: Medicare Part A does not cover long-term care (also called custodial care), if that's the only care you need.5 In our article on long-term care for seniors, we share critical details on insurance options and costs for long-term care.

Medicare Part B

Anyone who is eligible for Medicare Part A is also eligible for Medicare Part B. Medicare Part B covers preventative and medically necessary services. You can expect to pay a monthly premium for Medicare Part B coverage. If you're receiving Social Security, it will automatically be deducted from your check. If you're not receiving benefits yet, you'll get a bill for your Medicare Part B premium in the mail.

Preventative and medically necessary services covered by Medicare Part B6:

Pro Tip: Our Medicare Part B guide takes a deep dive into Medicare Part B's annual deductible, coinsurance, and out-of-pocket costs.

Medicare Advantage Plans (Medicare Part C)

Seniors who would like to pass on Original Medicare can opt for a Medicare Advantage Plan. These plans are sold by private companies that contract with Medicare to provide coverage. Medicare Advantage plans bundle Medicare Part A, Part B, and most often, a Part D Prescription Drug Plan. A considerable number of Medicare Part C plans also offer dental, vision, drug, and hearing coverage.

The downside to Part C is that many plans require you to see doctors and use services in network, so you may be limited in where you can receive health care services without paying big bucks for going out of network. Medicare Advantage Plans vary by state, so check with your local providers to determine what plans are available in your area.

Pro Tip: Shop around, because Medicare Advantage Plan pricing will vary! Head over to our Medicare Part C breakdown for the important cost details.

Medicare Part D

As you research your Medicare options, keep in mind that Original Medicare doesn't cover prescription medications. These out-of-pocket costs can derail your budget, especially if you're living on a fixed income.

Medicare Part D is optional and provides coverage for prescription drugs. During your initial enrollment period, carefully consider a Medicare Part D plan (even if you don't take prescriptions now). Late enrollment will result in a penalty that you will have to pay for as long as you have Medicare drug coverage.

From the pros: Our experts analyzed leading Medicare Part D providers across the nation to track down the best Medicare Part D plans.

Keep in mind that some Medicare Advantage Plans already offer prescription drug coverage. If you have Original Medicare, you can compare Medicare Part D plans and make selections by logging in to your Medicare.gov account.

Did you know you can save money on prescription drugs? Our editor-in-chief, Jeff Hoyt, shares essential information on the Medicare Extra Help program and State Pharmaceutical Assistance Programs in the video below.

FYI: Most states offer no-cost state health insurance assistance programs (SHIPs) to help seniors, their families, and caregivers navigate Medicare and enroll in plans. Find your local assistance program to get started.

Medigap (Medicare Supplement Health Insurance)

Medigap is different from a Medicare Advantage Plan, but it is similar in that the supplemental plan fills in where Original Medicare falls short. If you are already enrolled in a Medicare Advantage Plan, you can't dually enroll in a Medigap plan.

Medigap can help cover copays for Medicare Part A and Part B, as well as deductibles. If you spend a lot of time out of the country, Medigap will cover health care costs you accrue overseas, whereas Original Medicare does not. Remember, Medigap doesn't cover vision, dental, or long-term care. If you're in the market for dental coverage, visit our list of the best Medicare dental supplement plans.

What Is Medicaid?

Medicaid is a joint federal and state program that provides health coverage to low-income individuals in the U.S. In 2021, over 74 million Americans were enrolled in the program.7 States do have to stay within federal guidelines, but Medicaid services and coverage vary greatly by state.

Medicaid

Who Qualifies for Medicaid?

Your first step in qualifying for Medicaid is to be a U.S. citizen or a lawful permanent resident to be eligible for full benefits. Qualification for Medicaid is based on income. Whether you have a disability, the size of your family, and your age also factor into your eligibility. Though the qualifications vary by state, both your assets and your income are taken into consideration. Some older adults may qualify for both Medicare and Medicaid.

Quick Tip: Visit our guide to the Medicaid look-back period to learn how this policy can impact your eligibility for Medicaid.

Medicaid qualifications change year to year, so even if you didn't qualify in the past, it doesn't mean you never will. If your financial situation changes or your state expands Medicaid, you may qualify in the future. Unsure if you meet the eligibility requirements for Medicaid? Help is just a phone call away through your state's Medicaid agency.

How to Apply for Medicaid

There are two ways you can apply for Medicaid coverage:

  1. Contact your state's Medicaid agency.
  2. Fill out an application at HealthCare.gov.

What Does Medicaid Cover?

The federal government requires states to provide certain Medicaid benefits, while others are optional. Below is a list of mandatory benefits that all states are required to offer.

Mandatory Medicaid Benefits

  • Inpatient hospital services
  • Outpatient hospital services
  • EPSDT: Early and periodic screening, diagnostic, and treatment services
  • Nursing facility services
  • Home health services

  • Family planning services
