Medicare vs. Medicaid: An Overview

Medicare and Medicaid are U.S. government-sponsored programs designed to help cover health care costs for certain American residents. Established in 1965 and funded by taxpayers, these two programs have similar-sounding names, which can trigger confusion about how they work and the coverage they provide.

Medicare provides medical coverage for many people age 65 and older and those with a disability. Medicare does not limit enrollment based on income level. Medicaid is designed for people of any age with limited income and is often a program of last resort for those without access to other resources.

Key Takeaways

  • Medicare is the primary medical coverage provider for seniors and those with a disability.
  • Medicaid is designed for people with limited income.
  • Medicare has four parts that each cover different things—hospitalization, medically necessary services, supplemental coverage, and prescription drugs.

Medicare

Medicare helps provide health care coverage to U.S. citizens who are 65 years of age or older, as well as people with certain disabilities. The four-part program includes:

Part A: Hospitalization Coverage

Medicare Part A provides hospitalization coverage to individuals 65 years or older, regardless of income. You or your spouse must have worked and paid Medicare taxes for at least 10 years to qualify. Most people don't pay a premium for Part A, but deductibles and coinsurance apply.

Part B: Medical Insurance

Those eligible for Medicare Part A also qualify for Part B, which covers medically necessary services and equipment. This includes doctor’s office visits, lab work, X-rays, wheelchairs, walkers, and outpatient surgeries, as well as preventive services such as disease screenings and flu shots.

For 2024, the standard monthly Part B premium is $174.70, up from $164.90 in 2023. This is generally deducted from Social Security or Railroad Retirement payments. Deductibles and coinsurance apply. Individuals whose modified adjusted gross income (MAGI) is more than $103,000 per year ($206,000 for a couple) are obligated to pay more for this program.

Part B is optional, and if you have health insurance through an employer when you turn 65, you can wait to sign up. However, if you don't have employer-sponsored insurance and you decide later you want to sign up, you may have to pay a late-enrollment penalty.

Medicare Supplement Insurance, known as Medigap, may be purchased to help cover expenses such as copayments, coinsurance, and deductibles that go with Original Medicare. However, physicians who do not take Medicare also do not accept Medigap.

Part C: Medicare Advantage Plans

Individuals eligible for Medicare Part A and Part B are likewise eligible for Part C, also known as Medicare Advantage. Medicare Part C plans are offered by private companies approved by Medicare.

In addition to providing coverage offered by Parts A and B, most Part C plans offer prescription drug coverage. Many also provide vision, hearing, and dental coverage. Medicare Advantage plans often charge no premium or deductible, but may have higher coinsurance, deductibles, and copays than Original Medicare plans. Most Medicare Advantage plans also require you to see in-network providers, who must get preauthorizations before providing certain care, which can delay your treatment. Evaluate your health status along with the plan's structure and coverage to see if it's right for you.

Part D: Prescription Drug Coverage

Medicare Part D provides prescription drug coverage. Participants pay for Part D plans out of pocket and must pay monthly premiums, a yearly deductible, and copayments for certain prescriptions. Most Medicare Part C plans will not allow you to buy a separate Part D plan.

The annual Medicare open enrollment period runs from Oct. 15 to Dec. 7 every year.

2024 Medicare Costs at a Glance
Part A premium Free for most people who paid Medicare taxes for 40 or more quarters. If you paid Medicare taxes for less than 30 quarters, $505. If you paid Medicare taxes for 30–39 quarters, $278.
Part A hospital inpatient deductible and coinsurance $1,632 deductible for each benefit period, which covers the first 60 days of your stay Days 61–90 of your stay: $408/day coinsurance Days 61–90: $816/day coinsurance for "lifetime reserve days" (up to 60 days over your lifetime)
Part B premium $174.70
Part B deductible and coinsurance Deductible of $240 and then you pay 20%.
Part C premium Varies by plan
Part D premium Varies by plan

Medicaid

Medicaid is a joint federal and state program that helps low-income Americans of all ages pay for the costs associated with medical and long-term custodial care. Children who need low-cost care but whose families earn too much to qualify for Medicaid are covered through the Children's Health Insurance Program (CHIP), which has its own set of rules and requirements.

Medicaid Eligibility and Costs

The partnership between the federal and state governments means there are different Medicaid programs in each state. Through the Affordable Care Act (ACA), signed into law in 2010, President Barack Obama attempted to expand health care coverage to more Americans. As a result, all legal residents and citizens of the United States with incomes 150% below the poverty line qualify for coverage in Medicaid participating states.

While the ACA has worked to expand both federal funding and eligibility for Medicaid, the U.S. Supreme Court ruled that states are not required to participate in the expansion in order to receive their current level of Medicaid funding. As a result, many states have chosen not to expand funding levels and eligibility requirements.

People covered by Medicaid pay nothing for covered services. Unlike Medicare, which is available to nearly every American age 65 years and over, Medicaid has strict eligibility requirements that vary by state. For a state-by-state breakdown of eligibility requirements, visit Medicaid.gov.

When Medicaid recipients reach age 65, they remain eligible for Medicaid and also become eligible for Medicare. At that time, Medicaid coverage may change based on the recipient's income. Higher-income individuals may find that Medicaid just pays their Medicare Part B premiums. Lower-income individuals may continue to receive full benefits.

Medicaid Benefits

Medicaid benefits vary by state, but the Federal government mandates coverage for a variety of services, including:

  • Inpatient hospital services
  • Outpatient hospital services
  • EPSDT: Early and Periodic Screening, Diagnostic, and Treatment Services
  • Nursing Facility Services
  • Home health services
  • Physician services
  • Rural health clinic services
  • Federally qualified health center services
  • Laboratory and X-ray services
  • Family planning services
  • Nurse Midwife services
  • Certified Pediatric and Family Nurse Practitioner services
  • Freestanding Birth Center services (when licensed or otherwise recognized by the state)
  • Transportation to medical care
  • Tobacco cessation counseling for pregnant women

Each state also has the option of including additional benefits, such as prescription drug coverage, optometrist services, eyeglasses, medical transportation, physical therapy, prosthetic devices, dental services, and much more.

Medicaid is also used to fund long-term care, which is not covered by Medicare or most private health insurance policies. In fact, Medicaid is the primary payer of long-term care across the nation and often covers the cost of nursing facilities for those who deplete their savings to pay for health care and have no other means to pay for nursing care.

Frequently Asked Questions (FAQs)

What is the Difference Between Medicaid and Medicare?

Medicare is available to individuals based on age or disability. If your eligibility depends on age, you can't access the program until you turn 65. Medicaid is designed for individuals in low-income situations or other special circumstances.

How Can I Get Medicaid?

Not everyone qualifies for Medicaid. If your income falls below the poverty level, determined by your state, you might qualify. There are also a number of mandatory eligibility groups, including some pregnant women and children, and individuals receiving Supplemental Security Income.

Who Is Eligible for Both Medicare and Medicaid?

Medicare eligibility is for people who are 65 or older, or who have a disability, end-stage renal disease, or ALS (Lou Gehrig's disease). Medicaid is for low-income people or those who need long-term care and have run out of other resources for those payments. You may be dually eligible for both if, for instance, you are already on Medicaid and turn 65. People of any age with end-stage renal disease or ALS are also dually eligible.

The Bottom Line

Medicare and Medicaid are both government-run programs that cover health care costs. Medicare is open to Americans age 65 or older or who meet certain criteria, while Medicaid is designed for low-income Americans of any age, but with strict income requirements that vary by state.
