Introduction
Managed care is the dominant delivery system for people enrolled in Medicaid. The latest national Medicaid managed care enrollment data (from 2024) show 78% of Medicaid beneficiaries were enrolled in comprehensive managed care organizations (MCOs). While managed care is the dominant Medicaid delivery system, states decide which populations and services to include in managed care arrangements, which leads to considerable variation across states. Additionally, while state requirements for Medicaid managed care plans can be tracked, plans have flexibility in certain areas, including in setting provider payment rates, and plans may choose to offer additional benefits beyond those required by the state.
States and plans faced considerable rate settinguncertainty after millions of peoplewere disenrolled during the "unwinding" of the pandemic-era Medicaid continuous enrollment provision. Many states sought federal approval to adjust rates to address shifts in utilization and acuityas people who used fewer services than average were disenrolled, leaving a group with higher health risk and spending. Looking ahead, states expect the 2025 federal budgetreconciliation lawwill create additional managed care plan rate setting challenges as theMedicaid provisionsimpacting enrollment and spending (e.g., program financing changes, work requirements, and more frequent eligibility redeterminations) roll out over the next several years. Federal Medicaid spending cuts, coupled with a more tenuous fiscal climate (at the state-level), will haveimplicationsfor states and enrollees as well as plans and providers. In this context, this brief describes 10 themes related to the use of comprehensive, risk-based managed care in the Medicaid program.
1. Capitated managed care is the dominant way in which states deliver services to Medicaid enrollees.
States design and administer their own Medicaid programs within federal rules. States determine how they will deliver and pay for care for Medicaid beneficiaries. Nearly all states have some form of managed care in place comprehensive risk-based managed care (i.e., contracts with MCOs) and/or primary care case management (PCCM) programs.1, 2 As of
2.In FY 2024, payments to comprehensive risk-based MCOs accounted for half of Medicaid spending.
In FY 2024, state and federal spending on Medicaid services totaled
3. Over three-quarters (78%) of all Medicaid beneficiaries received their care through comprehensive risk-based MCOs.
As of
4. Children and adults are groups most likely to be enrolled in MCOs.
Among states that contract with comprehensive Medicaid MCOs, children and ACA expansion adults are the most likely to be enrolled in comprehensive MCOs (90% and 86%, respectively) (Figure 5). Nearly three quarters (72%) of "other adults" (e.g., parents and pregnant individuals) were enrolled in comprehensive MCOs (in 2023). People eligible for Medicaid through a disability pathway and adults ages 65+ are less likely to be enrolled in comprehensive MCOs, although states have been moving to include these groups in MCOs over time.
5. Five publicly traded firms account for almost half of MCO enrollment.
States contracted with a total of 291 Medicaid MCOs as of
6. States make decisions about which services to carve in and out of MCO contracts.
Although MCOs provide comprehensive services to beneficiaries, states may carve specific services out of MCO contracts to fee-for-service systems or limited benefit plans. Services frequently carved out include dental, non-emergency medical transportation (NEMT), and behavioral health. Among those enrolled in comprehensive MCOs, over two-thirds were also enrolled in at least one limited benefit prepaid health plan (PHP) and/or received fee-for-service (FFS) care outside of their MCO in 2023 (Figure 7). People with disabilities (enrolled in an MCO) are most likely to also be enrolled in a limited benefit plan(s) and/or receive FFS care. Individuals enrolled in multiple plans (i.e., MCO + limited benefit PHP(s)) or delivery systems (i.e., MCO + FFS) may have to juggle multiple complex systems, with differing rules. Among MCO enrollees also enrolled in at least one limited benefit plan, over half were enrolled in a dental plan (Figure 8). (Note that while EPSDT requires states to provide comprehensive dental services for children, dental benefits are optional for adults. State Medicaid programs are required to provide necessary transportation for enrollees to and from providers (referred to as "non-emergency medical transportation" or "NEMT").)
7. Each year, states develop MCO capitation rates that must be actuarially sound and may include risk mitigation strategies.
MCOs are at financial risk for services covered under their contracts, receiving aper member per month"capitation" payment for these services. While plans set rates in the commercial and Medicare Advantage markets, Medicaid managed care rates are developed by states and their actuaries and reviewed and approved by CMS. Capitation rates must be actuarially sound6 and are applied prospectively, typically for a 12-month rating period, regardless of changes in health care costs or utilization.States may use a variety ofrisk mitigation toolsto ensure payments are not too high or too low, including risk sharing arrangements, risk and acuity adjustments, or medical loss ratios (MLR) remittance requirements. States may also incorporate quality metrics into the ongoing monitoring of their programs, including linking financial incentives (e.g., performance bonuses or withholds) to quality measures.
To limit the amount that plans can spend on administration and keep as profit, states are required to develop capitation rates for Medicaid to achieve an MLR of at least 85% in the rate year;7 however, there is no federal requirement for Medicaid plans to pay remittances to the state if they fail to meet the MLR standard.8 As of
When significant enrollment, utilization, cost, and acuity changes began to emerge early in the COVID-19 public health emergency, CMS allowed states tomodifymanaged care contracts, and many states implementedCOVID-19related "risk corridors" (where states and health plans agree to share profit or losses), allowing for therecoupment of funds. States and plans faced another period of heightened rate setting uncertainty when thecontinuous enrollmentprovision expired on
8. Changes to federal state directed payment rules may impact provider payments.
States are generally prohibited from contractually directing how a managed care plan pays its providers.9Subject to CMS approval, however, states may implement certain "state directed payments" (SDPs)that require managed care plans to adopt minimum or maximum provider payment fee schedules, provide uniform dollar or percentage increases to providers (above base payment rates), or implement value-based payment (VBP) arrangements.10,11,12 Many states that contract with MCOs use SDPs to make uniform rate increases that are like FFS supplemental payments. Since SDPs were introduced in 2016, they have become a core component of reimbursement for many providers. Significant changes to state directed payment rules recently enacted through the 2025 federal budget reconciliation lawand through the 2024 CMS Managed Care rule are expected to affect Medicaid provider payment rates.
The reconciliation lawdirects HHS toreviseSDP regulations to cap the total payment rate for inpatient and outpatient hospital services, nursing facility services, and professional services at academic medical centers at 100% of the total published Medicare payment rate for states that have adopted the Medicaid expansion and at 110%13of the total published Medicare payment rate for states that have not adopted the expansion. (Under previous rules, payments were capped at 100% of average commercial rates.14) Certain SDPs areinitially grandfathered15but will be reduced by ten percentage points each year (starting
In addition to the 2025 reconciliation law changes, beginning in
9. CMS finalized rules to strengthen access standards, but the future of the rules is uncertain.
In 2024, the Biden administrationfinalized major Medicaid regulations designed to promote quality of care and advance access to care for Medicaid enrollees. The Managed Care rulestrengthens standards for timely access to care, including through the establishment of national maximum wait time standards for certain "routine" appointments, and states' monitoring and enforcement efforts. These rules are complex and set to be implemented over several years. It remains uncertain whether the Trump administration will seek to roll back or revise provisions included in the 2024 managed care final rules.
In 2024, CMS also finalized a rule focused on improving the prior authorization process including reducing approval wait times and improving transparency. A
While health insurers areincreasingly usingAI toautomateparts of the prior authorization process, there is limited information available about its use and impact within Medicaid managed care. MACPAC found that while there are potential benefits of automation in prior authorization such as administrative efficiencies and faster processing times, it may also pose potential risks or challenges depending on how it is administered and monitored. In the absence of comprehensive federal policy governing AI use and oversight in prior authorization,some stateshave taken steps to regulate or monitor use of AI by health plans.A 2025 KFF survey of state Medicaid directors found less than one-quarter of states reported requiring MCOs to disclose the use of AI in prior authorization processes as of
10. In recent years, CMS has taken steps to improve managed care program monitoring and transparency.
The 2016 Medicaid managed care final rule created new managed care reporting requirements for states. CMS, under the Biden administration, developed standard reporting templates (Table 1) and a variety of toolkits and released a series of informational bulletins (2021, 2022, 2023, 2024) to help states improve their monitoring and oversight of managed care programs. Transparency has the potential to promote accountability. To improve transparency, CMS began publicly posting the Managed Care Program Annual Report (MCPAR) and the MLR Summary Reports on Medicaid.gov in 2024. Posting data relating to the performance of individual MCOs may allow for comparison within and across states. However, limitations and challenges may exist.
Managed care rules finalized in 2024 include provisions aimed at further strengthening managed care transparency and monitoring, though the fate of these rules remains uncertain. In

Methods
Medicaid Managed Care Plan Enrollment by
This section provides information on the methods used in the analysis of Medicaid managed care plan enrollment by eligibility group (Figures 5, 7, and 8).
Data: This analysis uses data available from the 2023 T-MSISResearch Identifiable Demographic-Eligibility and Claims Files to identify enrollment in Medicaid managed care plans.
Medicaid enrollee inclusion criteria: Individuals were included if they had at least one month of Medicaid enrollment in 2023. This analysis identified Medicaid enrollment in a month (MM) in 2023 when CHIP_CD_01- CHIP_CD_12 equals 1 or, if missing CHIP_CD, when ELGBLTY_GRP_CD_01- ELGBLTY_GRP_CD_12 equals 1-60 or 69-75. Eligibility groups are defined using the most recent non-missing eligibility group in the calendar year (ELGBLTY_GRP_CD_LTST) and a person's age as follows:
Seniors:Enrollees age 65 and older.
People with Disabilities:Enrollees under age 65 who are reported as eligible because of disability.
Adults:Enrollees ages 19 to 64 who are not eligible because of disability or newly eligible for Medicaid by the ACA Medicaid expansion.
Children:Enrollees ages 18 and younger who are not eligible because of disability.
ACA Expansion Adults:Enrollees ages 19 to 64 who were made newly eligible for Medicaid by the ACA Medicaid expansion.
State inclusion criteria:To assess the usability of states' data, the analysis examined quality assessments from theDQ Atlasfor enrollment in managed care and payments to comprehensive managed care plans and compared enrollment in comprehensive managed care with theMedicaid Managed care enrollment report:
This analysis excluded 10 states with no comprehensive Medicaid managed care plans in 2023 (
Among states with Medicaid managed care, the analysis excluded states that had both a "Unclassified/ Unusable" DQ Atlas assessment and more than 50% difference between the number of individuals enrolled in managed care in T-MSIS and the number reported in the Medicaid managed care enrollment report.
No states were excluded based on those criteria in 2023, leaving the other 40 states and D.C. (hereafter, treated as a state) which contract with comprehensive MCOs in the main analysis. Enrollees were assigned a state based on their T-MSISSTATE_CD.
Identifying enrollment in Medicaid managed care plans: To determine enrollment in plans in 2023, individuals were assigned as enrolled in any plans from the list MC_PLAN_ID_01_MMMC_PLAN_ID_16_MM from the Managed Care Participation segment of the T-MSIS eligibility file. To determine enrollment in comprehensive MCOs, enrollment was limited to plans from the list MC_PLAN_ID_01_MMMC_PLAN_ID_16_MM from the Managed Care Participation segment of the T-MSIS eligibility file which also have a positive capitated payment to a plan on behalf of the enrollee in the month (MM) in the T-MSIS Other Services (OT) file. This analysis calculated positive capitated payment to a plan on behalf of the enrollee in a month by summing the MDCD_PD_AMT for claims with CLM_TYPE_CD equal to "2" (Medicaid or Medicaid-expansion Capitated Payment) having a SRVC_END_DT in the month in 2023. Capitated payments were attributed to a specific plan using the MC_PLAN_ID from the OT file.
Identifying Medicaid managed care plan types: This analysis used the Managed Care Participation segment of the T-MSIS eligibility file to map each plan as identified by its MC_PLAN_ID and STATE_CD to its plan type using the associated MC_PLAN_TYPE_CD. In cases where the plan as identified by MC_PLAN_ID and STATE_CD had more than one associated MC_PLAN_TYPE_CD in the Managed Care Participation segment of the T-MSIS eligibility file, the MC_PLAN_TYPE_CD with the largest number of enrollees in that plan was selected. This virtually always matches the MC_PLAN_TYPE_CD from the TAF Annual Managed Care Plan (APL).
KFF created indicator variables to assign the more detailed plan types into the following larger categories. Note that plan types are not mutually exclusive. For example, while there are no plans in 2023 have a MC_PLAN_TYPE_CD of 19 (Individual is enrolled in Long-Term Services and
Comprehensive managed care: having a MC_PLAN_TYPE_CD with values of 01 (Comprehensive managed care) or 04 (
Program of All-Inclusive Care for the Elderly (PACE): having a MC_PLAN_TYPE_CD with values of 17 (PACE).
Long-term care: having a MC_PLAN_TYPE_CD with values of 07 (Long Term Care Services and Supports (LTSS) PIHP) or 19 (Individual is enrolled in Long-Term Services and
Behavioral health: having a MC_PLAN_TYPE_CD with values of 08 (Mental Health (MH) PIHP), 09 (Mental Health (MH) PAHP), 10 (Substance Use Disorders (SUD) PIHP), 11 (Substance Use Disorders (SUD) PAHP), 12 (Mental Health (MH) and Substance Use Disorders (SUD) PIHP), 13 (Mental Health (MH) and Substance Use Disorders (SUD) PAHP), or 19 (Individual is enrolled in Long-Term Services and
Dental: having a MC_PLAN_TYPE_CD with values of 14 (Dental PAHP).
Transportation: having a MC_PLAN_TYPE_CD with values of 15 (Transportation PAHP).
Other limited benefit: having a MC_PLAN_TYPE_CD with values of 05 (Medical-only Prepaid Inpatient Health Plan (PIHP)), 06 (Medical-only Prepaid Ambulatory Health Plan (PAHP)), 16 (Disease Management PAHP), 18 (Pharmacy PAHP), or 20 (Other).
Any limited benefit: having a MC_PLAN_TYPE_CD with values defined above as long-term care, behavioral health, dental, transportation, or other limited benefit.
Primary care case management (PCCM): having a MC_PLAN_TYPE_CD with values of 02 (Traditional Primary Care Case Management (PCCM) Provider arrangement), or 03 (Enhanced PCCM Provider arrangement).
Managed long-term care (LTC) limited benefit plans: Using the definitions above, in 2023, virtually zero enrollees in long-term care limited benefit plans were concurrently enrolled in a comprehensive MCO. The likely reason there are no enrollees in comprehensive MCOs and limited benefit LTC plans is that most enrollees in limited benefit LTC plans also have Medicare. For such people ("dual-eligible individuals"), Medicaid covers medical acute and post-acute care, including skilled nursing facility services and home health care. Medicaid wraps around Medicare coverage by paying Medicare premiums and in most cases, cost sharing. Most people with Medicare and Medicaid ("dual-eligible individuals") also are eligible forMedicaid benefitsthat are not otherwise covered by Medicare, includinglong-term care,vision, and dental. It is unlikely that many dual-eligible individuals who are enrolled in LTC plans would also use many benefits provided through a comprehensive MCO.
