One of the key tests of the effectiveness of a health care coverage program is whether it provides access to appropriate health care services in a timely manner and whether those services promote health improvements. Learn more about MACPAC's work on how Medicaid and CHIP enrollees use health services.
Medicaid covers routine health services as well as benefits that are limited or not typically covered under other health insurance plans such as long-term services and supports, translation assistance, and non-emergency transportation services that are important to low-income seniors, adults with disabilities, and children with special health care needs. There are also specific rules affecting use of cost sharing and premiums. Learn more about Medicaid benefits.
Dually eligible beneficiaries are people enrolled in both Medicare and Medicaid by virtue of their age or disability and low incomes. This population is diverse and includes individuals with multiple chronic conditions, physical disabilities, mental illness, and cognitive impairments such as dementia and developmental disabilities. It also includes some individuals who are relatively healthy.
Dually eligible beneficiaries receive the same benefits as all other Medicare beneficiaries, but they may receive either full or partial Medicaid benefits. Full-benefit dually eligible beneficiaries receive full Medicaid benefits and may or may not receive help paying their Medicare premiums and cost sharing. Partial-benefit dually eligible beneficiaries only receive Medicaid assistance with their Medicare premiums and cost sharing. The Medicare Savings Programs (MSPs) provide assistance in paying for Medicare premiums and cost sharing for dually eligible beneficiaries who meet specific income and asset thresholds.
There were 10.7 million individuals dually enrolled in Medicare and Medicaid in calendar year 2013. A majority were age 65 and older (58 percent), female (61 percent), and qualified for Medicare because of a disability (52 percent).
Due to their complex health care needs, dually eligible beneficiaries account for a disproportionate share of spending in both Medicare and Medicaid. In Medicare, they represent 20 percent of enrollees but 34 percent of spending. In Medicaid, they represent 15 percent of enrollees and 32 percent of spending. Of the $312.4 billion in total spending on dually eligible beneficiaries by both Medicare and Medicaid in 2013, Medicaid accounted for $118.9 billion, or about 38 percent.

Medicaid covers people who would otherwise face considerable financial barriers to health care. Generally, a person must fall into a specific population group, referred to as categorical eligibility, and meet income thresholds in order to be eligible for Medicaid. Federal law mandates some of these eligibility groups; some are covered at state option. All states offer Medicaid coverage for low-income children, their parents, expectant mothers, seniors, and people with disabilities; some states have opted to expand eligibility further. To receive a full range of Medicaid benefits, individuals also must be U.S. citizens or qualified aliens. Learn more about eligibility pathways, eligibility and enrollment processes, and issues pertaining to specific populations.
The federal government and the states share responsibility for financing Medicaid. Historically, the federal share has averaged about 57 percent. With the new adult group under the Medicaid expansion receiving 100 percent federal match, the average federal share has increased to over 60 percent starting in 2014 (OACT 2016). General revenues fund federal spending for Medicaid, in contrast to Medicare, where funds in large part come from dedicated revenue sources that include payroll taxes and beneficiary premiums. Funding for the nonfederal, or state, share of Medicaid comes from a variety of sources; at least 40 percent must be financed by the state and up to 60 percent may come from local governments. In state fiscal year 2012, 69 percent of funds came from state general revenues, 16 percent from local governments (including intergovernmental transfers and certified public expenditures), 10 percent from health care related taxes, and 5 percent from other sources (GAO 2014).
Medicaid is the nation’s largest payer for long-term services and supports (LTSS). State Medicaid programs must cover services provided in nursing facilities as well as home health services (e.g., nursing services). States also cover other LTSS on an optional basis, including home and community-based services (HCBS) and services provided in intermediate care facilities for individuals with intellectual or developmental disabilities. States can include HCBS in their Medicaid benefit package using both state plan and waiver authorities.
LTSS accounts for a substantial share of Medicaid spending; in fiscal year (FY) 2015, Medicaid spent $158 billion on LTSS, accounting for almost one-third of Medicaid benefit spending.

Managed care is the primary Medicaid delivery system in more than half the states. States have incorporated managed care into their Medicaid programs for a number of reasons, including:
- Managed care provides states with some control and predictability over future costs.
- Compared with fee for service, managed care can allow for greater accountability for outcomes and can better support systematic efforts to measure, report, and monitor performance, access, and quality.
- Managed care programs may provide an opportunity for improved care management and care coordination.
Close to half of federal and state Medicaid spending in fiscal year 2016 (over $258 billion) was on managed care. The proportion continues to grow each year. As of 2015, 80 percent of Medicaid beneficiaries were enrolled in some form of managed care, up from about 56 percent in 2000. MACPAC annually compiles updated information on managed care spending and enrollment.
Perhaps the most widely discussed change that the Patient Protection and Affordable Care Act (ACA, P.L. 111-148, as amended) made to Medicaid was expanding eligibility to adults with incomes up to 138 percent of the federal poverty level (FPL). Originally a requirement, the Supreme Court ruling in June 2012 effectively made the Medicaid expansion an option, and to date, more than half of states have opted to expand. The ACA also made a number of other significant Medicaid changes, such as preventing states from reducing children’s Medicaid eligibility until FY 2019; setting a uniform standard for children’s eligibility at 138 percent FPL; streamlining eligibility, enrollment, and renewal processes; and updating payments to safety-net hospitals.
Medicaid interacts with other payers when Medicaid beneficiaries have other sources that are legally liable for payment of their medical costs. These may include private insurance, Medicare, other public programs such as the Ryan White program, workers’ compensation, and amounts received for injuries in liability cases. The program also interacts with CHIP when states provide Medicaid coverage to beneficiaries using CHIP funds.
High rates of spending growth for prescription drugs have been of great concern to state and federal Medicaid officials. In 2014, Medicaid prescription drug spending experienced its highest rate of growth in almost three decades. And although spending growth slowed in 2015 and 2016, over the next 10 years prescription drugs could see the fastest average annual spending growth of any major health care good or service due to growth in high-cost specialty drugs.

The Centers for Medicare & Medicaid Services (CMS) and the individual states and territories jointly administer Medicaid and the State Children’s Health Insurance Program (CHIP). CMS is responsible for program administration at the federal level. CMS approves state plans and state plan amendments, waivers, and demonstration programs; enforces compliance; and provides guidance to states.
States may offer Medicaid benefits on a fee-for-service (FFS) basis, through managed care plans, or both. Under the FFS model, the state pays providers directly for each covered service received by a Medicaid enrollee. Under managed care, the state pays a fee to a managed care plan for each person enrolled in the plan. In turn, the plan pays providers for all of the Medicaid services an enrollee may require that are included in the plan's contract with the state. Learn more about how Medicaid programs pay providers and structure the delivery of care.

State Medicaid programs cover substance use disorder treatment and supportive services to varying degrees. They are working to integrate care for physical health and treatment for substance use disorders across providers and with other social programs. They also are implementing programs to reduce opioid overprescribing in order to prevent opioid use disorder from developing in the first place. Many of these efforts are being undertaken in conjunction with other state and federal initiatives.
In fiscal year (FY) 2015, total Medicaid spending was $556 billion. Of this amount, $351 billion was federal spending and $205 billion was state spending. This represents:
- 16.4 percent of U.S. health care spending (2014),
- 9.5 percent of federal outlays (FY 2015),
- 61 percent of spending on long-term services and supports (2012), and
- 26 percent of spending on mental health and substance abuse (2009).

The State Children's Health Insurance Program (CHIP) is a joint federal-state program established to provide coverage to uninsured children in families whose incomes are too high to qualify for Medicaid. In fiscal year (FY) 2016, 8.9 million children received CHIP-funded coverage. Spending in states and territories for FY 2016 totaled $15.6 billion ($14.4 billion federal, $1.2 billion state). Under current law, CHIP allotments are provided through FY 2027. Learn more about CHIP and MACPAC's analysis of its future.
