Medicaid Made Clear: What Medicaid is, who Medicaid serves & the history of Medicaid

What is Medicaid?


Medicaid is a federal and state program that provides health care coverage to qualified individuals. 

Medicaid programs are state-run. However, the federal government has rules and regulations under which all states must comply. The federal government also provides at least 50% of the funding for their Medicaid requirements.

Based on federal regulations, states create and run their own Medicaid program to best serve their residents who qualify. States may choose to provide more services than the federal government requires and they may also choose to provide coverage to larger groups of people.

Medicaid provides health care coverage for people who qualify, based on income and assets.

History of Medicaid


Medicaid began as part of the Social Security Act of 1965. The original law gave states the option of receiving federal funding to help provide health care coverage to children whose families have a low income, their caregiver relatives, people who are blind and people who are disabled. Throughout time, the federal government has strengthened the rules and requirements for states administering Medicaid. Through Medicaid expansion some states now extend coverage to other low-income adults.

Who does Medicaid serve?


Pregnant women with low income
Children of low income families
Children in foster care
People with disabilities
Seniors with low income
Parents or caregivers with low income

States may choose to expand eligibility to additional groups, like such as people with low income who may or may not have children

What is the Federal Poverty Level?


The Federal Poverty Level (FPL) accounts for the minimum amount of gross income that a family needs for food, clothing, transportation, shelter and other necessities. The calculation is used to determine eligibility in multiple federal assistance programs. It is recalculated every year.

Each group of people eligible for Medicaid must meet certain FPL eligibility thresholds.

What advantages does managed care provide to states?

Correct!

States can authorize the use of managed care organizations (MCOs) to provide services to their Medicaid population. This helps states manage risk to taxpayers, control costs, make costs more predictable and improve care for those served by the program. The most common type of managed care structure is a comprehensive risk-based managed care arrangement, where a state contracts with an MCO, paying them a fixed dollar amount per member. 2/3 of Americans enrolled in Medicaid are served by Medicaid managed care.
