This week 红领巾瓜报 (红领巾瓜报), draws on its database of monthly Medicaid managed care enrollment to present its latest quarterly analysis, offering a snapshot of enrollment trends across 37 states.
The analysis comes at a critical time. As states prepare for Medicaid eligibility policy changes that take effect in 2027鈥攊ncluding more frequent eligibility determinations and expanded work and community engagement requirements鈥攃urrent enrollment trends provide an early signal of how policy decisions and administrative practices are already influencing coverage levels.
The 红领巾瓜报 Information Services (红领巾瓜报IS) analysis shows that Medicaid managed care accounted for 85.6 percent of total Medicaid enrollment in December 2025. This analysis, available to 红领巾瓜报IS subscribers, uses data from nearly 300 health plans in 41 states.鈥疶he report provides by-plan enrollment plus corporate ownership, program inclusion, and for-profit versus not-for-profit status, with breakout tabs for publicly traded plans.
Key Insights from Q4 2025 Data
The 37 states included in this review have released monthly Medicaid managed care enrollment data through public websites or in response to a public records request from 红领巾瓜报. The report includes the most recent data obtained and illustrates the effect of state-level choices around eligibility and administration. Key findings include:
- As of聽December聽2025,聽Medicaid managed care enrollment across the 37 states declined by聽2.2 million members聽year over year, falling to 62.5 million鈥攁聽3.4 percent decrease.聽
- Of the 37 states,聽eight鈥擟olorado, Delaware, Mississippi, Missouri, New Jersey, North Carolina, North Dakota, and Oregon鈥攄id聽not聽experience year-over-year聽managed care enrollment聽declines,聽and聽instead showed聽flat enrollment or modest gains.聽With the exception of Mississippi, these聽are聽all聽Medicaid expansion states.聽
- Arizona聽and Indiana聽experienced聽double-digit聽percentage聽declines. Notably,聽Indiana began requiring聽enrollees聽to actively respond to renewal mailers,聽which aligns with聽enrollment declines that began in March 2025.聽
- Among the聽expansion states in the analysis,聽enrollment聽declined聽by聽1.7聽million (-3.3%) to聽50.8聽million.聽The聽seven non-expansion states聽experienced聽a聽similar聽decline (-3.6%),聽bringing聽enrollment to聽11.7聽million enrollees.聽
Data Considerations. The data have some important limitations. States report enrollment figures at different points during the month, with some data reflecting beginning of the month totals and others capturing end of the month enrollment. In addition, some state datasets encompass all Medicaid programs offering managed care plans, whereas others reflect only a subset of the managed Medicaid population. As a result, the findings should be viewed as indicative of broader trends rather than a comprehensive state-by-state comparison.鈥&苍产蝉辫;
Market Share and Plan Dynamics
Using our data repository for 300 health plans across 41 states, 红领巾瓜报IS analyzes corporate ownership, program participation, and tax status among Medicaid managed care plans. As of December 2025, Centene maintained the largest share of the national Medicaid managed care market at 17.8 percent, followed by Elevance (10.4%), United (8.5%), and Molina (6.0%) (see Figure 1).鈥疶hese figures highlight continued concentration among large national plans, even as overall enrollment declines.

What to Watch鈥
Enrollment trends observed in the fourth quarter (Q4) of 2025 and continuing into 2026 indicate increasing state attention to eligibility policy and program integrity. State legislative activity, budget pressures, and federal regulatory developments are prompting many states to assess and strengthen certain aspects of their programs related to eligibility, particularly as they prepare to implement redetermination and work and community engagement requirements.
Several states are already moving toward implementation. Nebraska is scheduled to launch Medicaid work requirements on May 1,聽2026,聽while Montana plans to begin implementation on July 1, 2026. With聽additional聽federal guidance still聽emerging, most other states are working toward compliance ahead of January 2027 deadlines.聽In聽expansion聽states,聽policymakers聽retain聽authority to tighten administrative processes, alter optional benefits, or adjust provider payment levels鈥攁ctions that聽may聽materially affect enrollment.聽
These developments underscore why Medicaid managed care enrollment trends deserve close attention. Declines in enrollment are often an early indicator of broader system impacts, including rising uncompensated care for providers, shifts in payer mix, and increased financial pressure on safety鈥憂et systems. For managed care organizations, even modest enrollment changes can mask more significant shifts in risk profiles, geographic concentration, or service needs.
