Over ** million Americans were estimated to be enrolled in the Medicaid program as of 2023. That is a significant increase from around ** million ten years earlier. Medicaid is basically a joint federal and state health program that provides medical coverage to low-income individuals and families. Currently, Medicaid is responsible for ** percent of the nation’s health care bill, making it the third-largest payer behind private insurances and Medicare. From the beginning to ObamacareMedicaid was implemented in 1965 and since then has become the largest source of medical services for Americans with low income and limited resources. The program has become particularly prominent since the introduction of President Obama’s health reform – the Patient Protection and Affordable Care Act - in 2010. Medicaid was largely impacted by this reform, for states now had the opportunity to expand Medicaid eligibility to larger parts of the uninsured population. Thus, the percentage of uninsured in the United States decreased from over ** percent in 2010 to *** percent in 2022. Who is enrolled in Medicaid?Medicaid enrollment is divided mainly into four groups of beneficiaries: children, adults under 65 years of age, seniors aged 65 years or older, and disabled people. Children are the largest group, with a share of approximately ** percent of enrollees. However, their share of Medicaid expenditures is relatively small, with around ** percent. Compared to that, disabled people, accounting for **** percent of total enrollment, were responsible for **** percent of total expenditures. Around half of total Medicaid spending goes to managed care and health plans.

This data set presents annual enrollment counts of Medicaid and CHIP beneficiaries by managed care participation (comprehensive managed care, primary care case management, MLTSS, including PACE, behavioral health organizations, nonmedical prepaid health plans, medical-only prepaid health plans, and other). There are three metrics presented: (1) the number of beneficiaries ever enrolled in each managed care plan type over the year (duplicated count); (2) the number of beneficiaries enrolled in each managed care plan type as of an individual’s last month of enrollment (duplicated count); and (3) average monthly enrollment in each managed care plan type. These metrics are based on data in the T-MSIS Analytic Files (TAF). Some cells have a value of “DS”. Some states have serious data quality issues, making the data unusable for calculating these measures. To assess data quality, analysts used measures featured in the DQ Atlas. Data for a state and year are considered unusable or of high concern based on DQ Atlas thresholds for the topics Enrollment in CMC, Enrollment in PCCM Programs, and Enrollment in BHO Plans. Please refer to the DQ Atlas at http://medicaid.gov/dq-atlas for more information about data quality assessment methods. Some cells have a value of “DS”. This indicates that data were suppressed for confidentiality reasons because the group included fewer than 11 beneficiaries.

The Medicaid Managed Care Enrollment Report profiles enrollment statistics on Medicaid managed care programs on a plan-specific level. The managed care enrollment statistics include enrollees receiving comprehensive benefits and limited benefits and are point-in-time counts. Because Medicaid beneficiaries may be enrolled concurrently in more than one type of managed care program (e.g., a Comprehensive MCO and a BHO), users should not sum enrollment across all program types, since the total would count individuals more than once and, in some states, exceed the actual number of Medicaid enrollees. Comprehensive MCOs cover acute, primary, and specialty medical care services; they may also cover behavioral health, long-term services and supports, and other benefits in some states. Limited benefit managed care programs, including PCCM, MLTSS only, BHO, Dental, Transportation, and Other cover a narrower set of services. 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. "--" indicates states that do not operate programs of a given type. 0 signifies that a state operated a program of this type in 2014, but it ended before July 1, 2014, or began after that date.

The number of people enrolled in Medicaid increased by 6.5 percent in 2023, while expenditure increased by 8.3 percent. Due to Medicaid unwinding in 2024 Medicaid enrollment is projected to decline by 8.6 percent, while the spending is expected to grow by 3.4 percent.

Impact of COVID-19 on Medicaid Approximately 18 percent of Americans were covered by Medicaid in 2020. The total number of Medicaid enrollees continues to increase each year and is projected to surpass 75 million in 2019. A steadily improving economy in the United States is one reason for the slower enrollment growth experienced in recent years. However, unemployment numbers surged due to the COVID-19 pandemic, and Medicaid enrollment is expected to rise over the coming months as millions of people lose their employer-based health insurance.

Medicaid expenditure set to increase Medicaid expenditure in 2019 was projected to 640 billion U.S. dollars, an increase year on year. Medicaid spending rose by 7.1 percent in 2020, but the economic downturn caused by COVID-19 is likely to significantly increase both state and federal expenditures. More people are now eligible for Medicaid because they have lost income, and the costs of coronavirus testing and treatment are escalating. Many states may not have the budget to pay for it all, especially at a time when tax revenues are declining.

In 2022, nearly 59 percent of Medicaid and CHIP enrollees were aged between 18 and 64 years, while adults aged 65 years accounted for only 17.4 percent of enrollees. Medicaid program is funded jointly by the federal and the state governments, it provided coverage to nearly 19.5 percent of the U.S. population in 2022.

Medicaid vs CHIP

Medicaid and the Children’s Health Insurance Program (CHIP) both provide health insurance coverage for children from low-income families. Children who are not eligible for Medicaid but who would otherwise be unable to obtain insurance through a family plan are covered by CHIP. More than five million children were enrolled in CHIP in the U.S. in 2023.

Medicaid and CHIP funding rate

The Federal Medical Assistance Percentages (FMAPs) are used to calculate the amount of federal matching funds for State Medicare and CHIP programs. To encourage states to expand coverage for uninsured children the federal matching rates for CHIP are generally 15 points higher than the Medicaid rate. However, unlike permanent federal funding for Medicaid, CHIP federal funding is capped and due to expire in FY 2027.

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.

There were approximately 28.1 million children enrolled in the Medicaid health care program in 2018, which accounted for nearly 40 percent of the total number of 74 million Medicaid enrollees. Enrollment numbers in each of the four groups have been consistent for several years.

Medicaid expenditure by eligibility group Medicaid is a joint federal and state health care program in the United States. States administer the program, but they must meet some core federal requirements, one of which includes providing health coverage to children in some low-income families. Medicaid expenditure on children was estimated to have totaled 107.2 billion U.S. dollars in 2017, which accounted for nearly 20 percent of the total expenditure during the year – the only enrollment group with a larger share of expenditures was persons with disabilities.

Health insurance options for children The Children’s Health Insurance Program (CHIP) was signed into U.S. law in 1997 and increased health coverage to uninsured children under the age of 19 who were not eligible for Medicaid. States can implement CHIP by expanding Medicaid or operating it as a separate program. More than 9.6 million children were enrolled in the program during 2018, around two million of whom were in the state of California.

This dataset represents the number of Medicaid eligible individuals receiving the various Medicaid services over time.

This dataset aggregates and displays the number of New York State Medicaid enrollees by eligibility year and month within each NYS Economic Region, health insurance plan information, and enrollee demographics.

This data set presents annual enrollment counts of Medicaid and CHIP beneficiaries by major eligibility group (children, adult expansion group, adult, aged, persons with disabilities, or COVID newly-eligible). There are three metrics presented: (1) the number of beneficiaries ever enrolled in each major eligibility group over the year (duplicated count); (2) the number of beneficiaries enrolled in each major eligibility group as of an individual’s last month of enrollment (unduplicated count); and (3) average monthly enrollment in each major eligibility group.

These metrics are based on data in the T-MSIS Analytic Files (TAF). Some states have serious data quality issues, making the data unusable for calculating these measures. To assess data quality, analysts used measures featured in the DQ Atlas. Data for a state and year are considered unusable or of high concern based on DQ Atlas thresholds for the topic Eligibility Group Code. Please refer to the DQ Atlas at http://medicaid.gov/dq-atlas for more information about data quality assessment methods.

Some cells have a value of “DS”. This indicates that data were suppressed for confidentiality reasons because the group included fewer than 11 beneficiaries.

This data set includes annual counts and percentages of Medicaid and Children’s Health Insurance Program (CHIP) enrollees who received a well-child visit paid for by Medicaid or CHIP, overall and by five subpopulation topics: age group, race and ethnicity, urban or rural residence, program type, and primary language. These results were generated using Transformed Medicaid Statistical Information System (T-MSIS) Analytic Files (TAF) Release 1 data and the Race/Ethnicity Imputation Companion File. This data set includes Medicaid and CHIP enrollees in all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands, except where otherwise noted. Enrollees in Guam, American Samoa, and the Northern Mariana Islands are not included. Results include enrollees with comprehensive Medicaid or CHIP benefits for all 12 months of the year and who were younger than age 19 at the end of the calendar year. Results shown for the race and ethnicity subpopulation topic exclude enrollees in the U.S. Virgin Islands. Results shown for the primary language subpopulation topic exclude select states with data quality issues with the primary language variable in TAF. Some rows in the data set have a value of "DS," which indicates that data were suppressed according to the Centers for Medicare & Medicaid Services’ Cell Suppression Policy for values between 1 and 10. This data set is based on the brief: "Medicaid and CHIP enrollees who received a well-child visit in 2020." Enrollees are identified as receiving a well-child visit in the year according to the Line 6 criteria in the Form CMS-416 reporting instructions. Enrollees are assigned to an age group subpopulation using age as of December 31st of the calendar year. Enrollees are assigned to a race and ethnicity subpopulation using the state-reported race and ethnicity information in TAF when it is available and of good quality; if it is missing or unreliable, race and ethnicity is indirectly estimated using an enhanced version of Bayesian Improved Surname Geocoding (BISG) (Race and ethnicity of the national Medicaid and CHIP population in 2020). Enrollees are assigned to an urban or rural subpopulation based on the 2010 Rural-Urban Commuting Area (RUCA) code associated with their home or mailing address ZIP code in TAF (Rural Medicaid and CHIP enrollees in 2020). Enrollees are assigned to a program type subpopulation based on the CHIP code and eligibility group code that applies to the majority of their enrolled-months during the year (Medicaid-Only Enrollment; M-CHIP and S-CHIP Enrollment). Enrollees are assigned to a primary language subpopulation based on their reported ISO language code in TAF (English/missing, Spanish, and all other language codes) (Primary Language). Please refer to the full brief for additional context about the methodology and detailed findings. Future updates to this data set will include more recent data years as the TAF data become available.

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.

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.

This dataset represents the number of Medicaid eligible individuals receiving the various Medicaid services over time.

California has more Medicaid and CHIP enrollees than any other state in the United States. As of April 2023, approximately 13 million Americans were enrolled in the Medicaid health insurance programs in California, which accounted for approximately 15 percent of the total number of Medicaid enrollees nationwide (94.4 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 97.8 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 five 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 255 percent of the federal poverty level.
