The percentage of Americans covered by the Medicaid public health insurance plan increased from **** percent in 2020 to around **** percent in 2023. However, the percentage of those insured through Medicaid remains lower than the peak of **** percent in 2015. The expansion of Medicaid The Affordable Care Act (ACA) provided the option for states to expand Medicaid eligibility to people whose income was below a particular threshold. The ACA’s major coverage expansion came into force in 2014, and the number of individuals estimated to be enrolled in Medicaid has since surpassed ** million. More than ** million children were enrolled in the program in 2018, representing ** percent of overall Medicaid enrollment. State Medicaid coverage Initially, the ACA mandated that all state Medicaid programs would have to be extended to provide medical coverage to nearly all low-income groups. However, the Supreme Court rejected that part of the act in 2012, leaving the door open for states to make their own decision on whether they expand their plans. As of September 2021, ** states plus the District of Columbia have adopted the Medicaid expansion.

In 2023, just four in ten Medicaid/CHIP enrollees were White, non-Hispanic. In comparison, roughly three-quarters of Medicare beneficiaries were White. The Affordable Care Act (ACA) Medicaid expansion in 2014, has helped reduce racial disparities in access to healthcare in the United States. Medicaid eligibility Medicaid provides health coverage to certain low-income individuals, families, children, pregnant women, the elderly, and persons with disabilities. Each state has its own Medicaid eligibility criteria in accordance with federal guidelines. As a result, Medicaid eligibility and benefits differ widely from state to state. Medicaid expansion provision under the Affordable Care Act (ACA) allows states to provide coverage for low-income adults by expanding eligibility for Medicaid to 138 percent of the federal poverty line (FPL). Medicaid coverage gap Uninsured individuals who live in states that have chosen not to expand Medicaid under the Affordable Care Act (ACA) are referred to as being in the Medicaid coverage gap. As of January 2021, 12 states have not adopted the Medicaid expansion provision under the Affordable Care Act (ACA). More than two million uninsured adults fall into this coverage gap, and among them, more than 60 percent are people of color.

As of August 1, 2024, approximately 2.5 million Medicaid enrollees have been disenrolled in Texas, the highest number of people disenrolled across all states in the United States. Overall, more than 24.5 million people in the United States have lost their Medicaid coverage, the majority of those terminations were for so-called procedural reasons, which means that the enrollees did not finish the renewal process for various reasons.

California has more Medicaid and CHIP enrollees than any other state in the United States. As of April 2023, approximately ** million Americans were enrolled in the Medicaid health insurance programs in California, which accounted for approximately ** percent of the total number of Medicaid enrollees nationwide (**** million). Blow to Medicaid expansion plans California is one of many states that has expanded its Medicaid program under the Affordable Care Act (ACA) to encourage more low-income adults to sign up for health coverage. One of the original aims of the ACA was to limit some of the variations in state Medicaid programs, but the Supreme Court ruled that the expansion should be optional. Governors of the states that did not expand said they were concerned about long-term costs. California is the leading state for Medicaid expenditure, spending approximately **** billion U.S. dollars in FY2020. Health coverage for children The Children’s Health Insurance Program (CHIP) was created as a complement to Medicaid, expanding the reach of government-funded health coverage to more children in low-income families. As of May 2021, over **** million children were enrolled in Medicaid/CHIP programs in California, more than any other state. As of January 2021, the median Medicaid/CHIP eligibility level for children was *** percent of the federal poverty level.

The Share of Medicaid Enrollees in any Managed Care and in Comprehensive Managed CaAre profiles state-level enrollment statistics (numbers and percentages) of total Medicaid enrollees in any type of managed care as well as those enrolled specifically in comprehensive managed care programs. The report provides managed care enrollment by state with all 50 states, the District of Columbia and the US territories are represented in these data. Note: "n/a" indicates that a state or territory was not able to report data or does not have a managed care program. The “Total Medicaid Enrollees” column represents an unduplicated count of all beneficiaries in FFS and any type of managed care, including Medicaid-only and dually eligible individuals receiving full Medicaid benefits or Medicaid cost sharing. The “Total Medicaid Enrollment in Any Type of Managed Care” column represents an unduplicated count of beneficiaries enrolled in any Medicaid managed care program, including comprehensive MCOs, limited benefit MCOs, PCCMs, and PCCM entities. The “Medicaid Enrollment in Comprehensive Managed Care” column represents an unduplicated count of Medicaid beneficiaries enrolled in a managed care plan that provides comprehensive benefits (acute, primary care, specialty, and any other), as well as PACE programs. It excludes beneficiaries who are enrolled in a Financial Alignment Initiative Medicare-Medicaid Plan as their only form of managed care.

In the fiscal year 2023, Medicaid expenditure in California amounted to a total of about 124 billion U.S. dollars, of which 81.3 billion U.S. dollars were federal-funded and approximately 43 billion U.S. dollars were state-funded. California had, as expected, the highest spending and also the largest number of people enrolled in Medicaid in the United States. The Federal Medical Assistance Percentage (FMAP) varies by state depending on the state's per capita income compared to the national average.

This map shows where people have Medicaid or means-tested healthcare coverage in the US (ages under 65).

Metrics from individual Marketplaces during the current reporting period. The report includes data for the states using State-based Marketplaces (SBMs) that use their own eligibility and enrollment platforms Source: State-based Marketplace (SBM) operational data submitted to CMS. Each monthly reporting period occurs during the first through last day of the reported month. SBMs report relevant Marketplace activity from April 2023 (when unwinding-related renewals were initiated in most SBMs) through the end of a state’s Medicaid unwinding renewal period and processing timeline, which will vary by SBM. Some SBMs did not receive unwinding-related applications during reporting period months in April or May 2023 due to renewal processing timelines. SBMs that are no longer reporting Marketplace activity due to the completion of a state’s Medicaid unwinding renewal period are marked as NA. Some SBMs may revise data from a prior month and thus this data may not align with that previously reported. For April, Idaho’s reporting period was from February 1, 2023 to April 30, 2023. Notes: This table represents consumers whose Medicaid/CHIP coverage was denied or terminated following renewal and 1) whose applications were processed by an SBM through an integrated Medicaid, CHIP, and Marketplace eligibility system or 2) whose applications/information was sent by a state Medicaid or CHIP agency to an SBM through an account transfer process. Consumers who submitted applications to an SBM that can be matched to a Medicaid/CHIP record are also included. See the "Data Sources and Metrics Definition Overview" at http://www.medicaid.gov for a full description of the differences between the SBM operating systems and resulting data metrics, measure definitions, and general data limitations. As of the September 2023 report, this table was updated to differentiate between SBMs with an integrated Medicaid, CHIP, and Marketplace eligibility system and those with an account transfer process to better represent the percentage of QHP selections in relation to applicable consumers received and processed by the relevant SBM. State-specific variations are: - Maine’s data and Nevada’s April and May 2023 data report all applications with Medicaid/CHIP denials or terminations, not only those part of the annual renewal process. - Connecticut, Massachusetts, and Washington also report applications with consumers determined ineligible for Medicaid/CHIP due to procedural reasons. - Minnesota and New York report on eligibility and enrollment for their Basic Health Programs (BHP). Effective April 1, 2024, New York transitioned its BHP to a program operated under a section 1332 waiver, which expands eligibility to individuals with incomes up to 250% of FPL. As of the March 2024 data, New York reports on consumers with expanded eligibility and enrollment under the section 1332 waiver program in the BHP data. - Idaho’s April data on consumers eligible for a QHP with financial assistance do not depict a direct correlation to consumers with a QHP selection. - Virginia transitioned from using the HealthCare.gov platform in Plan Year 2023 to an SBM using its own eligibility and enrollment platform in Plan Year 2024. Virginia's data are reported in the HealthCare.gov and HeathCare.gov Transitions Marketplace Medicaid Unwinding Reports through the end of 2024 and is available in SBM reports as of the April 2024 report. Virginia's SBM data report all applications with Medicaid/CHIP denials or terminations, not only those part of the annual renewal process, and as a result are not directly comparable to their data in the HealthCare.gov data reports. - Only SBMs with an automatic plan assignment process have and report automatic QHP selections. These SBMs make automatic plan assignments into a QHP for a subset of individuals and provide a notification of options regarding active selection of an alternative plan and/or, if appli

Children accounted for 36.5 percent of Medicaid enrollees in 2021, which was the largest share of all enrollment groups. The elderly and persons with disabilities had the smallest shares, but together they accounted for more than half of all Medicaid expenditure.

Medicaid expenditures per enrollee Medicaid is a joint federal and state health care program in the United States. The program provides medical coverage to millions of Americans and supports a variety of enrollment groups, particularly senior citizens and individuals with disabilities. Medicaid per enrollee spending is significantly higher for these two groups because they require more frequent and costly long-term care in the community and nursing homes. In 2022 of the total U.S. health expenditure on home health care, Medicaid paid one-third.

Millions of Americans are uninsured The United States has a multi-payer health care system, meaning that some Americans will be covered by private health insurance, and others will be covered by a government program such as Medicaid. However, approximately 27.6 million people in the U.S. had no health insurance in 2021, and should they require health care, they would have to pay the full price out of their own pocket. This becomes a real problem for many because the United States has the most expensive health care system in the world.

Medicaid is an important public health insurance for individuals with a low income, those that are pregnant, disabled or are children. It was projected that by 2020 there would be approximately 76.7 million Medicaid enrollees. By 2027 that number is expected to increase to 82 million individuals covered.

Medicaid in the focus

Medicaid has recently been in the news for several reasons. A proposed Medicaid expansion was announced with the implementation of the Affordable Care Act in 2010. According to the expansion, all states were given the option to expand Medicaid programs to help provide insurance coverage to millions of U.S. Americans. As of 2019, 32 states have accepted federal funding to expand their Medicaid programs. Medicaid, after Medicare and private insurance, provides a significant proportion of the total health expenditures in the United States. In general, Medicaid expenditure, like the number of enrollees, has been growing over time.

Medicaid demographics

A significant proportion of Medicaid enrollees in the U.S. are children and low-income adults. Despite children accounting for most of the enrollees in the Medicaid program, the largest percentage of expenditures for Medicaid is dedicated to those enrolled as a disabled individual. Expenditures for the program also vary regionally. The states with the highest Medicaid expenditures include California, New York and Texas, to name a few.

Metrics from individual Marketplaces during the current reporting period. The report includes data for the states using HealthCare.gov. As of August 2024, CMS is no longer releasing the “HealthCare.gov” metrics. Historical data between July 2023-July 2024 will remain available. The “HealthCare.gov Transitions” metrics, which are the CAA, 2023 required metrics, will continue to be released. Sources: HealthCare.gov application and policy data through May 5, 2024, and T-MSIS Analytic Files (TAF) through March 2024 (TAF version 7.1 with T-MSIS enrollment through the end of March 2024). Data include consumers in HealthCare.gov states where the first unwinding renewal cohort is due on or after the end of reporting month (state identification based on HealthCare.gov policy and application data). State data start being reported in the month when the state's first unwinding renewal cohort is due. April data include Arizona, Arkansas, Florida, Indiana, Iowa, Kansas, Nebraska, New Hampshire, Ohio, Oklahoma, South Dakota, Utah, West Virginia, and Wyoming. May data include the previous states and the following new states: Alaska, Delaware, Georgia, Hawaii, Montana, North Dakota, South Carolina, Texas, and Virginia. June data include the previous states and the following new states: Alabama, Illinois, Louisiana, Michigan, Missouri, Mississippi, North Carolina, Tennessee, and Wisconsin. July data include the previous states and Oregon. All HealthCare.gov states are included in this version of the report. Notes: This table includes Marketplace consumers who: 1) submitted a HealthCare.gov application on or after the start of each state’s first reporting month; and 2) who can be linked to an enrollment record in TAF that shows Medicaid or CHIP enrollment between March 2023 and the latest reporting month. Cumulative counts show the number of unique consumers from the included population who had a Marketplace application submitted or a HealthCare.gov Marketplace policy on or after the start of each state’s first reporting month through the latest reporting month. Net counts show the difference between the cumulative counts through a given reporting month and previous reporting months. The data used to produce the metrics are organized by week. Reporting months start on the first Monday of the month and end on the first Sunday of the next month when the last day of the reporting month is not a Sunday. For example, the April 2023 reporting period extends from Monday, April 3 through Sunday, April 30. Data are preliminary and will be restated over time to reflect consumers most recent HealthCare.gov status. Data may change as states resubmit T-MSIS data or data quality issues are identified. Data do not represent Marketplace consumers who had a confirmed Medicaid/CHIP loss. Future reporting will look at coverage transitions for people who lost Medicaid/CHIP. See the data and methodology documentation for a full description of the data sources, measure definitions, and general data limitations. Data notes: Virginia operated a Federally Facilitated Exchange (FFE) on the HealthCare.gov platform during 2023. In 2024, the state started operating a State Based Marketplace (SBM) platform. This table only includes data on 2023 applications and policies obtained through the HealthCare.gov Marketplace. Due to limited Marketplace activity on the HealthCare.gov platform in December 2023, data from December 2023 onward are excluded. The cumulative count and percentage for Virginia and the HealthCare.gov total reflect Virginia data from April 2023 through November 2023. The report may include negative 'net counts,' which reflect that there were cumulatively fewer counts from one month to the next. Wyoming has negative ‘net counts’ for most of its metrics in March 2024, including 'Marketplace Consumers with Previous M

The following table provides eligibility levels in each state for key coverage groups that use Modified Adjusted Gross Income (MAGI), as of April 1, 2018. The data represent the principal, but not all, MAGI coverage groups in Medicaid, the Children’s Health Insurance Program (CHIP), and the Basic Health Program (BHP). All income standards are expressed as a percentage of the federal poverty level (FPL). The MAGI-based rules generally include adjusting an individual’s income by an amount equivalent to a 5% FPL disregard. Other eligibility criteria also apply, such as citizenship, immigration status, and state residency.

In 2021, 27 percent of Hispanic people in non-Medicaid expansion states were uninsured, this was almost double in comparison to 15 percent in Medicaid expansion states. In general, most ethnic groups are more likely to be uninsured in non-Medicaid expansion states compared to expansion states. This statistic shows the share of population by ethnicity without health insurance in the United States in 2021, by state Medicaid expansion status.

Metrics from individual Marketplaces during the current reporting period. The report includes data for the states using HealthCare.gov. Sources: HealthCare.gov application and policy data through October 6, 2024, HealthCare.gov inbound account transfer data through November 7, 2024, and T-MSIS Analytic Files (TAF) through July 2024 (TAF version 7.1). The table includes states that use HealthCare.gov. Notes: This table includes Marketplace consumers who submitted a HealthCare.gov application from March 6, 2023 - October 6, 2024 or who had an inbound account transfer from April 3, 2023 - November 7, 2024, who can be linked to an enrollment record in TAF that shows a last day of Medicaid or CHIP enrollment from March 31, 2023 - July 31, 2024. Beneficiaries with a leaving event may have continuous coverage through another coverage source, including Medicaid or CHIP coverage in another state. However, a beneficiary that lost Medicaid or CHIP coverage and regained coverage in the same state must have a gap of at least 31 days or a full calendar month. This table includes Medicaid or CHIP beneficiaries with full benefits in the month they left Medicaid or CHIP coverage. ‘Account Transfer Consumers Whose Medicaid or CHIP Coverage was Terminated’ are consumers 1) whose full benefit Medicaid or CHIP coverage was terminated and 2) were sent by a state Medicaid or CHIP agency via secure electronic file to the HealthCare.gov Marketplace in a process referred to as an inbound account transfer either 2 months before or 4 months after they left Medicaid or CHIP. 'Marketplace Consumers Not on Account Transfer Whose Medicaid or CHIP Coverage was Terminated' are consumers 1) who applied at the HealthCare.gov Marketplace and 2) were not sent by a state Medicaid or CHIP agency via an inbound account transfer either 2 months before or 4 months after they left Medicaid or CHIP. Marketplace consumers counts are based on the month Medicaid or CHIP coverage was terminated for a beneficiary. Counts include all recent Marketplace activity. HealthCare.gov data are organized by week. Reporting months start on the first Monday of the month and end on the first Sunday of the next month when the last day of the reporting month is not a Sunday.

2023 saw the largest expenditures on Medicaid in U.S. history. At that time about 894 billion U.S. dollars were expended on the Medicaid public health insurance program that aims to provide affordable health care options to low income residents and people with disabilities. Medicaid was signed into law in 1965. By 1975 around 13 billion U.S. dollars were spent on the program. Groups covered by Medicaid There are several components of the Medicaid health insurance program. The Children’s Health Insurance Program (CHIP) was started in 1997 to provide health coverage to families and children that could not afford care. As of 2021, children represented the largest distribution of Medicaid enrollees. Despite having the largest proportion of enrollees, those that were enrolled in Medicaid as children had the lowest spending per enrollee. As of 2021, disabled Medicaid enrollees had the highest spending per enrollee. Medicaid expenditures Currently, Medicaid accounts for 19 percent of all health care expenditure in the United States. Expenditures on Medicaid programs vary among the U.S. states and depend heavily on whether Medicaid expansion was accepted after the Affordable Care Act was enacted. California and New York are the top states with the highest Medicaid expenditures. It is projected that Medicaid expenditure will continue to increase at both the state and federal levels.

The percentage of people in the United States with health insurance has increased over the past decade with a noticeably sharp increase in 2014 when the Affordable Care Act (ACA) was enacted. As of 2023, around ** percent of people in the United States had some form of health insurance, compared to around ** percent in 2010. Despite the increases in the percentage of insured people in the U.S., there were still over ** million people in the United States without health insurance as of 2023. Insurance coverage Health insurance in the United States consists of different private and public insurance programs such as those provided by private employers or those provided publicly through Medicare and Medicaid. Almost half of the insured population in the United States were insured privately through an employer as of 2021, while **** percent of people were insured through Medicaid, and **** percent through Medicare . The Affordable Care Act The Affordable Care Act (ACA), enacted in 2014, has significantly reduced the number of uninsured people in the United States. In 2014, the percentage of U.S. individuals with health insurance increased to almost ** percent. Furthermore, the percentage of people without health insurance reached an all time low in 2022. Public opinion on healthcare reform in the United States remains an ongoing political issue with public opinion consistently divided.

During a public health emergency in the Families First Coronavirus Response Act (FFCRA), a new optional Medicaid eligibility group was added called COVID-19 testing eligibility group. States reported these expenditures under sections 6004 and 6008 through the Medicaid Budget and Expenditure System (MBES) on the Form CMS-64. The data in these reports constitute summary level preliminary expenditure information related to these FFCRA provisions for each state

Notes: 1. The Families First Coronavirus Response Act (FFCRA), enacted on March 18, 2020, provided a temporary FMAP increase to states and territories meeting certain qualifications and added a new optional

In 2023, 25 million people in the United States had no health insurance. The share of Americans without health insurance saw a steady increase from 2015 to 2019 before starting to decline in 2020 to 2023. Factors like the implementation of Medicaid expansion in additional states and growth in private health insurance coverage led to the decline in uninsured population, despite the economic challenges due to the pandemic in 2020. Positive impact of Affordable Care Act In the U.S. there are public and private forms of health insurance, as well as social welfare programs such as Medicaid and programs just for veterans such as CHAMPVA. The Affordable Care Act (ACA) was enacted in 2010, which dramatically reduced the share of uninsured Americans, though there’s still room for improvement. In spite of its success in providing more Americans with health insurance, ACA has had an almost equal number of proponents and opponents since its introduction, though the share of Americans in favor of it has risen since mid-2017 to the majority. Persistent disparity among ethnic groups The share of uninsured people is higher in certain demographic groups. For instance, Hispanics continue to be the ethnic group with the highest rate of uninsured people, even after ACA. Meanwhile the share of uninsured White and Asian people is lower than the national average.

Context

This public dataset was created by the Centers for Medicare & Medicaid Services. The data summarize counts of enrollees who are dually-eligible for both Medicare and Medicaid program, including those in Medicare Savings Programs. “Duals” represent 20 percent of all Medicare beneficiaries, yet they account for 34 percent of all spending by the program, according to the Commonwealth Fund . As a representation of this high-needs, high-cost population, these data offer a view of regions ripe for more intensive care coordination that can address complex social and clinical needs. In addition to the high cost savings opportunity to deliver upstream clinical interventions, this population represents the county-by-county volume of patients who are eligible for both state level (Medicaid) and federal level (Medicare) reimbursements and potential funding streams to address unmet social needs across various programs, waivers, and other projects. The dataset includes eligibility type and enrollment by quarter, at both the state and county level. These data represent monthly snapshots submitted by states to the CMS, which are inherently lower than ever-enrolled counts (which include persons enrolled at any time during a calendar year.)
