Total Medicaid spending surpassed 804 billion U.S. dollars in 2022. The state of California had the highest expenditure throughout the year, followed by New York and Texas.

Federal government helps poorer states Both the federal and state governments fund the Medicaid health care program, but at least 50 percent of the costs incurred by states are matched by the federal government. The exact percentage varies by state because the matching rate was designed so that poorer states receive a larger share of program costs from the federal government. The states of Wyoming, South Dakota, North Dakota, spent the least on Medicaid costs in 2021.

Funding share of states set to increase Under the Affordable Care Act, states have the choice to expand their Medicaid programs to cover nearly all low-income Americans under age 65. For states that implemented the expansion, the federal government paid 100 percent of the state costs for all newly eligible adults from 2014 to 2016. The new matching rate has slowly declined since and reached 90 percent in 2020, which means states have to pick up ten percent of the bill. Governors are concerned about the rise in costs, and state expenditure is projected to increase by 50 percent between 2020 and 2027.

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.

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 **** million Medicaid enrollees. By 2027 that number is expected to increase to ** 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, ** 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.

This statistic presents the total Medicaid spending in the United States in the federal fiscal year 2022, listed by state. In that fiscal year, New Jersey's total Medicaid expenditure was approximately **** billion U.S. dollars. Medicaid spending in the U.S. Medicaid spending varies widely between states. California expended almost ***** billion U.S. dollars in 2022 while Wyoming spent some *** billion U.S. dollars in the same year. Medicaid is a health program that targets families and individuals earning a low-income in the United States. Each state is able to determine the eligibility of individuals to enter the program. Children are among the largest group enrolled in Medicaid, however, almost ** percent of Medicaid spending is targeted towards individuals that are disabled. About ** percent of Medicaid expenditures are used for acute care and some ** percent used for long-term care. Medicaid since the ACA The establishment of the Affordable Care Act increased state and federal spending dedicated to Medicaid. In 1990, the federal government spent **** billion U.S. dollars and the state government spent **** billion U.S. dollars on Medicaid. Since then, federal and state spending increased to *** billion U.S. dollars and *** billion U.S. dollars, respectively, in 2019. Expenditures on this health insurance are expected to continue its trend, increasing to over ************ U.S. dollars by 2027. Medicaid is the largest public health insurance program in the United States and covers roughly ** million citizens in the country.

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.

In 2022, Medicare and Medicaid national health expenditures reached 944 billion U.S. dollars and 805 billion U.S. dollars, respectively. The largest expense category for both healthcare care programs was hospital care. Long-term care solutions Medicaid’s second-largest expense category was other health care, which includes programs that provide alternatives to long-term institutional services. The use of home- and community-based services can substantially reduce expenditures for enrollees who would otherwise have to receive care in an institutional setting, such as a nursing home. In recent decades, there has been a significant shift in the distribution of Medicaid’s long-term care services expenditures. Medicaid’s federal-state partnership Medicare is a health insurance program solely funded by the federal government, whereas Medicaid plays an important role in both federal and state budgets. The federal government establishes certain parameters for all states to follow, but states can decide who gets coverage and what gets covered in its version of Medicaid. In 2021, California was the state with the highest Medicaid expenditure.

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:

1. 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 applicable, making the first month’s premium payment.
2. SBMs report on all applicable applications received and not on the Medicaid-defined cohorts of individuals whose renewal is due in a given month. The data in this table are not cumulative and count unique Marketplace activities during the reporting period month in which the relevant activity occurs. As such, activities by any one consumer may be included across reporting months. For example, a consumer who submits an application and receives a determination of QHP eligibility may be counted in one month but his/her plan selection could be counted in a later month. Thus, the percentages do not necessarily depict a direct correlation to the count of consumers on applications received during the current reporting month. Total counts represent activity across the reporting months and are not cumulative as of the latest reporting month. Updated applications in the reporting month are only counted once. Updated applications in a following month may be counted again in that applicable month only if the consumer obtains a new Medicaid/CHIP renewal.
3. SBMs have different operational processes and eligibility systems for handling QHP, Medicaid and CHIP eligibility determinations. While CMS works with SBMs to align the metric definitions across the Marketplaces there can be limitations and anomalies among the SBM data due to different SBM system capabilities. Additionally, variances in the data may be attributable to differences in how states are conducting unwinding renewals including processing timelines and whether states are staging applications for population cohorts (e.g., over age 65).

Percentages shown are of consumers on applications whose Medicaid/CHIP coverage was denied or terminated following renewal during the reporting period month.
Percentages shown are of consumers on account transfers whose Medicaid/CHIP coverage was denied or terminated following renewal during the reporting period month. The percentages for SBMs with integrated eligibility systems and the SBM Total - Integrated and SBM Total data record groups are marked as not available (NA) because SBMs with integrated eligibility systems do not receive account transfers. Additionally, some SBMs with account transfer processes adjusted, with guidance from CMS, the count of "Consumers on Account Transfers Associated with a Medicaid/CHIP Coverage Denial or Termination Following Renewal" to include all consumers on applications who are associated with a Medicaid/CHIP coverage denial or termination following renewal for purposes of calculating the Percent - Account Transfer data record group. For example, Pennsylvania conducts automatic QHP eligibility determinations for Marketplace plans for some account transfers and as of the December 2023 report, revised its data to report those consumers in the account transfer and application metrics. As of the April 2024 report, New Jersey revised its data to report consumers on account transfers and direct applications in the account transfer and application metrics to reflect overall SBM activity in the Percent - Account Transfer data record group.

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.

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 statistic represents the distribution of Medicaid spending, by service, for the state of New Jersey in federal fiscal year 2022. Approximately 12 percent of total Medicaid spending went to acute care during this year.

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.)

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.

In the state of California, there were approximately *** million children enrolled in Medicaid and CHIP insurance plans in March 2025. Additionally, Texas, New York, and Florida all had more than *** million children enrolled in the programs. How many people are enrolled in Medicaid/CHIP? State Medicaid programs provide medical coverage to millions of Americans, including children, pregnant women, and parents. The Children’s Health Insurance Program (CHIP) was introduced in 1997 to help uninsured children who were previously not eligible for Medicaid. The total number of individuals enrolled in Medicaid and CHIP was approximately **** million in May 2021, and California has the largest state program. How is income eligibility determined? The Affordable Care Act established a new methodology to assess income eligibility for Medicaid and CHIP. The adoption of the Modified Adjusted Gross Income (MAGI) methodology helped to align eligibility rules that previously varied nationwide. In general, an individual’s eligibility is now determined by their MAGI and where it falls in relation to the federal poverty level (FPL). For Medicaid and CHIP plans across all states in 2021, the median upper income eligibility level for children was *** percent of the FPL.

This report provides information at the state and town level of people served by the Connecticut Department of Social Services for the Calendar Years 2012-2024 by demographics (gender, age-groups, race, and ethnicity) at the state and town level by Medical Benefit Plan (Husky A-D, Husky limited benefit, MSP and Other Medical); Assistance Type (Cash, Food, Medical, Other); and Program (CADAP, CHCPE, CHIP, ConnTRANS, Medicaid, Medical, MSP, Refugee Cash, Repatriation, SAGA, SAGA Funeral, SNAP, Social Work Services, State Funded Medical, State Supplement, TFA). NOTE: On March 2020, Connecticut opted to add a new Medicaid coverage group: the COVID-19 Testing Coverage for the Uninsured. Enrollment data on this limited-benefit Medicaid coverage group is being incorporated into Medicaid data effective January 1, 2021. Enrollment data for this coverage group prior to January 1, 2021, was listed under State Funded Medical. Effective January 1, 2021, this coverage group have been separated: (1) the COVID-19 Testing Coverage for the Uninsured is now G06-I and is now listed as a limited benefit plan that rolls up into “Program Name” of Medicaid and “Medical Benefit Plan” of HUSKY Limited Benefit; (2) the emergency medical coverage has been separated into G06-II as a limited benefit plan that rolls up into “Program Name” of Emergency Medical and “Medical Benefit Plan” of Other Medical. NOTE: On April 22, 2019 the methodology for determining HUSKY A Newborn recipients changed, which caused an increase of recipients for that benefit starting in October 2016. We now count recipients recorded in the ImpaCT system as well as in the HIX system for that assistance type, instead using HIX exclusively. Also, the methodology for determining the address of the recipients has changed: 1. The address of a recipient in the ImpaCT system is now correctly determined specific to that month instead of using the address of the most recent month. This resulted in some shuffling of the recipients among townships starting in October 2016. 2. If, in a given month, a recipient has benefit records in both the HIX system and in the ImpaCT system, the address of the recipient is now calculated as follows to resolve conflicts: Use the residential address in ImpaCT if it exists, else use the mailing address in ImpaCT if it exists, else use the address in HIX. This change in methodology causes a reduction in counts for most townships starting in March 2017 because a single address is now used instead of two when the systems do not agree. NOTE: On February 14 2019, the enrollment counts for 2012-2015 across all programs were updated to account for an error in the data integration process. As a result, the count of the number of people served increased by 13% for 2012, 10% for 2013, 8% for 2014 and 4% for 2015. Counts for 2016, 2017 and 2018 remain unchanged.

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. HealthCare.gov data are through Sunday, October 6. 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. See the data and methodology documentation for a full description of the data sources, measure definitions, and general data limitations. Data notes: The percentages for the 'Marketplace Consumers Not on Account Transfer whose Medicaid or CHIP Coverage was Terminated' data record group are marked as not available (NA) because the full population of consumers without an account transfer was not available for this report. 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 about 2023 applications and policies obtained through the HealthCare.gov Marketplace. Due to limited Marketplace activity on the HealthCare.gov platform in November 2023, data from November 2023 onward are excluded.

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.

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:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. See the data and methodology documentation for a full description of the data sources, measure definitions, and general data limitations.

Data notes:

1. 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.
2. The report may include negative 'net counts,' which reflect that there were cumulatively fewer counts from one month to the next.
3. Wyoming has negative ‘net counts’ for most of its metrics in March 2024, including 'Marketplace Consumers with Previous Medicaid or CHIP Enrollment.' Negative counts reflect that there were cumulatively fewer individual counts from one month to the next. The net percentages have been replaced with an asterisk for March 2024 due to the uninterpretable values.

Percentages shown are of total Marketplace consumers with previous Medicaid or CHIP enrollment.
Some cells have a value of "NR" or not reported. State data starts being reported in the month when the state's first unwinding renewal cohort is due.
