What is the difference between medicare and medicaid programs

Q: What’s the difference between Medicare and Medicaid?

A: Medicare and Medicaid are two important U.S. healthcare programs. Each program serves different groups of people, although some people are enrolled in both programs.

Who does Medicare cover?

Medicare is a federal government-sponsored healthcare program for those 65 and over, and for younger people who are disabled (Medicare covers 64 million Americans; more than 8.1 million of them were under age 65 as of late 2021). Most people with Medicare paid FICA taxes during their working years, and realize the benefits of that tax through Medicare coverage. The federal government establishes the eligibility criteria for Medicare.

Who does Medicaid cover?

Medicaid, on the other hand, is a healthcare program for low-income individuals who could not otherwise afford health insurance. Nearly 77 million Americans were enrolled in Medicaid as of mid-2021, plus another 7 million enrolled in CHIP.

Medicaid is jointly funded by the federal government and the state in which an enrollee lives. States establish their own eligibility standards and services for Medicaid, within general parameters set by the federal government. Before the Affordable Care Act (ACA), most states only provided Medicaid coverage to people who were low-income and also either disabled, elderly, pregnant, children, or the caretaker of a minor child. These populations had to be covered according to federal law.

The ACA included a provision to expand Medicaid eligibility to more adults in every state as of January 1, 2014, but a Supreme Court ruling in 2012 made Medicaid expansion optional. As of 2022, there are still 12 states that have not expanded Medicaid. In the District of Columbia and the 38 states where Medicaid has been expanded, coverage is available for anyone with an income up to 138% of the poverty level (in the continental U.S., that amounts to about $18,754 in annual income for a single adult in 2022).

Here’s more information on Medicaid in each state, and where the states are in terms of Medicaid expansion under the ACA.

What are my coverage options under Medicare?

Original Medicare coverage is the same in every state, including eligibility, benefits, and premiums. A Medicare beneficiary pays the same price for Medicare Part B, regardless of where the beneficiary lives (although premiums for Part B do vary based on other factors).

But a significant portion of Medicare’s coverage is provided through private plans. The private plan options under Medicare — including Medicare Part D (prescription coverage), Medigap (supplemental coverage), and Medicare Advantage — vary considerably from one area to another in terms of which insurers offer coverage, the specific plan designs they offer, and the pricing. Most of the general regulations that apply to those plans are the same in every state. State regulations for Medigap plans do vary considerably, however. Federal rules do not require Medigap insurers to offer coverage to disabled enrollees under age 65, but the majority of the states have implemented their own rules to ensure at least some access to Medigap plans for these enrollees. You can click on a state on this map to see applicable Medigap rules.

Medicare plan options and costs are subject to change each year.

  • Medicare and Medicaid are two U.S. government programs designed to provide access to healthcare.
  • Medicare covers citizens age 65 and over, as well as those with certain chronic conditions or disabilities.
  • Medicaid is typically available to those with a lower income and helps provide healthcare services at little or no cost.

The terms Medicaid and Medicare are often confused or used interchangeably. They sound extremely similar, but these two programs are actually very different.

Each is regulated by its own set of laws and policies, and the programs are usually designed for different sets of people. However, it is possible to be eligible for both programs.

To select the correct program for your needs, it’s important to understand the differences between Medicare and Medicaid.

Medicare is a policy designed for U.S. citizens age 65 and older who have difficulty covering the expenses related to medical care and treatments. This program provides support to senior citizens and their families who need financial assistance for medical needs.

People under the age of 65 living with certain disabilities may also be eligible for Medicare benefits. Each case is evaluated based on eligibility requirements and the details of the program.

Those in the final stage of kidney disorders can also apply for the benefits of a Medicare policy.

There are two main branches of Medicare to choose from — original Medicare and Medicare Advantage.

Original Medicare

Original Medicare is a government-funded medical insurance option that many older Americans use Medicare as their primary insurance. It covers:

  • Inpatient hospital services (Medicare Part A). These benefits include coverage for hospital visits, hospice care, and limited skilled nursing facility care and at-home healthcare.
  • Outpatient medical services (Medicare Part B). These benefits include coverage for preventive, diagnostic, and treatment services for health conditions.

Medicare Advantage

Medicare Advantage (Part C) is an insurance option for people who want the coverage of original Medicare but with more coverage choices.

Medicare Advantage plans are offered through private insurance companies. Many of these plans cover services like prescription drug coverage, dental, vision, and hearing care that aren’t included in original Medicare.

Medicaid is a program that combines the efforts of the U.S. state and federal governments to assist households in low-income groups with healthcare expenses. These costs may include major hospitalizations and treatments as well as routine medical care.

The program provides services to millions of adults, children, and people with disabilities each year. In November 2020, 72,204,587 individuals were in enrolled in Medicaid, and 6,695,834 children were enrolled in Children’s Health Insurance Program (CHIP).

Medicare costs

People receiving Medicare benefits pay part of the cost through deductibles for things like hospital stays. For coverage outside the hospital, such as a doctor’s visit or preventive care,

Medicare requires small monthly premiums. There may also be some out-of-pocket costs for things like prescription drugs.

Here is an overview of the costs with original Medicare and Medicare Advantage:

Medicaid costs

People receiving Medicaid benefits often don’t have to pay for covered expenses at all, but some cases require a small copayment.

States can charge limited premiums and enrollment fees as a form of cost sharing. This applies to certain groups of Medicaid enrollees, including:

  • pregnant women and infants with a household income at or above 150 percent of the federal poverty level (FPL)
  • qualified disabled and working individuals with an income above 150 percent of the FPL
  • disabled working individuals eligible under the Ticket to Work and Work Incentives Improvement Act of 1999
  • disabled children eligible under the Family Opportunity Act
  • medically needy individuals

To enroll in each program, you must meet certain criteria.

Medicare eligibility

In most situations, eligibility for Medicare is based on the age of the applicant. A person must be a citizen or permanent resident of the United States and 65 years old or older to qualify.

Premiums and specific Medicare plan eligibility will depend on how many years of Medicare taxes have been paid. The exception to this is people younger than age 65 who have certain documented disabilities.

Generally, people who receive Medicare benefits also receive some form of Social Security benefits. Medicare benefits can also be extended to:

  • a person eligible for the Social Security disability program who’s also the widow or widower and is age 50 or older
  • the child of a person who worked a minimum length of time at a government job and paid Medicare taxes

Medicaid eligibility

Eligibility for Medicaid is based primarily on income. Whether or not someone qualifies depends on income level and family size.

The Affordable Care Act has extended coverage to fill in the healthcare gaps for those with the lowest incomes, establishing a minimum income threshold constant across the country. To find out if you qualify for assistance in your state, visit Healthcare.gov.

For the majority of adults under age 65, eligibility is an income lower than 133 percent of the federal poverty level. According to Healthcare.gov, this amount for 2021 is approximately $12,880 for an individual and $26,500 for a family of four.

Children are afforded higher income levels for Medicaid and the CHIP based on the individual standards of their state of residence.

There are also special programs within the Medicaid program that extend coverage to groups in need of immediate assistance, such as pregnant women and those with pressing medical needs.

Medicare coverage

There are several parts of the Medicare program that offer coverage for different aspects of healthcare.

Medicare Part A is provides coverage for many inpatient medical care, such as hospital stays, hospice services, and limited skilled nursing care and home healthcare.

Medicare Part B is the outpatient medical portion. It offers coverage for items and services including outpatient hospital care, physician appointments, preventive care, and certain medical equipment.

Medicare Part C, or Medicare Advantage, is run by approved private insurers and includes all the benefits of Medicare parts A and B. These plans may also include other benefits for an extra cost, like dental and vision, as well as prescription drug coverage.

Medicare Part D is run by approved plans according to federal rules and helps pay for prescription drugs.

Medicaid coverage

The benefits covered by Medicaid vary by state, but there are some benefits included in every program.

These include:

  • lab and X-ray services
  • inpatient and outpatient hospital services
  • family planning services, such as birth control and nurse midwife services
  • health screenings and applicable medical treatments for children
  • nursing facility services for adults
  • surgical dental services for adults

Because Medicaid is different in each state, you may want to connect with a caseworker in your state to assess your situation and get help applying.

People who qualify for both Medicare and Medicaid are considered dual eligible. In this case, you may have original Medicare (parts A and B) or a Medicare Advantage plan (Part C), and Medicare will cover your prescription drugs under Part D.

Medicaid may also cover other care and drugs that Medicare doesn’t, so having both will probably cover most of your healthcare costs.

Medicare and Medicaid are two U.S. government programs designed to help different populations get access to healthcare.

Medicare typically covers citizens age 65 and over and those with certain chronic conditions or disabilities, while Medicaid eligibility is mainly based on income level and need.
