People who are dually eligible for Medicare and Medicaid remain a central focus for policymakers and healthcare organizations, given their complex care needs, disproportionate share of spending, and the long-standing challenge of coordinating coverage across two programs. One of the primary vehicles for advancing integration has been Dual Eligible Special Needs Plans (D-SNPs), which continue to play an increasingly prominent role as federal and state policymakers encourage tighter Medicare-Medicaid alignment.

As states play a more active role in shaping enrollment rules, Medicaid contracting, and procurement strategies, the duals market is becoming more structured and more explicitly guided by state policy decisions. Health Management Associates (HMA’s) 2026 Duals Integration Environmental Inventory, examines how this shift shapes the integration landscape in 2026. This comprehensive inventory is based on a review of the 2026 market, insights from states, and other publicly available resources.

This article examines key trends from HMA’s 2026 inventory and addresses federal policy changes scheduled to take effect for 2027, which contribute to this dynamic environment.

What to Expect in 2026

As the landscape for duals integration evolves, the central question has shifted from whether D-SNPs operate in a state to the more consequential question of how states are using Medicaid policy levers (i.e., enrollment rules, procurement, contracting, and managed care structures) to drive tighter alignment between Medicare and Medicaid. 

At the federal level, recent Medicare Advantage and Part D rulemaking is reinforcing that movement. The Contract Year 2025 Medicare Advantage and Part D Final Rule finalized the second phase-down of the D-SNP look-alike threshold to 60 percent for 2026 and established 2027 rules that limit enrollment in certain D-SNPs to members of an affiliated Medicaid managed care organization. The rule also limits the number of D-SNP benefit packages that can be offered alongside an affiliated Medicaid managed care organization. More recently, the Contract Year 2026 Medicare Advantage and Part D Final Rule requires certain D-SNPs to use integrated member ID cards and integrated health risk assessments beginning in 2027. 

Together these rules signal a continued federal emphasis on linking D-SNP enrollment and operations more closely to Medicaid coverage and delivery systems, with states playing a greater role in determining how alignment is achieved. 

What the 2026 Inventory Shows

HMA’s 2026 Duals Integration Environmental Inventory shows how these policy signals are translating into state action. More specifically: 

• Statewide exclusively aligned enrollment appears in 16 states in the 2026 inventory, up from nine in 2025. 
• Applicable Integrated Plans (AIPs) are present in 22 states, up from 14, and default enrollment is in place in 21 states, up from 16. 
• The inventory also captures 6,084,997 total D-SNP enrollees, including 1,975,250 in Highly Integrated SNPs (HIDE) and 743,683 in Fully Integrated SNPs (FIDE-SNPs). 

Those changes are already visible in state markets: 

• Illinois, Massachusetts, Ohio, and Rhode Island entered 2026 with a greater FIDE-SNP presence tied to legacy Medicare-Medicaid Plan transitions. 
• Michigan launched MI Coordinated Health as a HIDE-SNP in selected regions in 2026, with statewide expansion planned for 2027. 
• Delaware also stands out: Although it already had AIPs in the 2025 inventory, it adds statewide exclusively aligned enrollment in 2026 and shows both HIDE-SNPs and coordination-only D-SNPs. 

A Resource to Track State Market Direction

HMA’s 2026 Duals Integration Environmental Inventory, available to HMA Information Services (HMAIS) subscribers, includes a state-by-state view of the Medicaid policy, contracting, and program structures shaping duals integration and D-SNP markets. In addition to enrollment trends, the inventory documents the integration model each state is pursuing, whether long-term services and supports or behavioral health are included in managed care, and how procurement and contract decisions may inform future market activity. 

HMA experts work with clients to apply this information and deepen their understanding of state integration approaches, inform assessments of their market readiness and alignment opportunities, and develop strategies that support more effective Medicare-Medicaid integration. 

Looking Ahead

Notably, HMA’s inventory reflects a point in time understanding of where an individual state is today and what is known at this time about their next steps and plans. However, we expect changes in many states as they seek guidance from the Centers for Medicare & Medicaid Services and the D-SNP community to implement required changes and adopt new regulatory provisions that support state goals and priorities. 

The 2026 inventory suggests that more states are using formal alignment tools, that more enrollment is concentrated in integrated products, and that more markets are being shaped by the interaction between Medicaid structure, procurement, and D-SNP strategy.

This week Health Management Associates (HMA), 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—including more frequent eligibility determinations and expanded work and community engagement requirements—current enrollment trends provide an early signal of how policy decisions and administrative practices are already influencing coverage levels. 

The HMA Information Services (HMAIS) analysis shows that Medicaid managed care accounted for 85.6 percent of total Medicaid enrollment in December 2025. This analysis, available to HMAIS subscribers, uses data from nearly 300 health plans in 41 states. The 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 HMA. 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 December 2025, Medicaid managed care enrollment across the 37 states declined by 2.2 million members year over year, falling to 62.5 million—a 3.4 percent decrease. 
• Of the 37 states, eight—Colorado, Delaware, Mississippi, Missouri, New Jersey, North Carolina, North Dakota, and Oregon—did not experience year-over-year managed care enrollment declines, and instead showed flat enrollment or modest gains. With the exception of Mississippi, these are all Medicaid expansion states. 
• Arizona and Indiana experienced double-digit percentage declines. Notably, Indiana began requiring enrollees to actively respond to renewal mailers, which aligns with enrollment declines that began in March 2025. 
• Among the expansion states in the analysis, enrollment declined by 1.7 million (-3.3%) to 50.8 million. The seven non-expansion states experienced a similar decline (-3.6%), bringing enrollment to 11.7 million enrollees. 

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.  

Market Share and Plan Dynamics 

Using our data repository for 300 health plans across 41 states, HMAIS 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). These figures highlight continued concentration among large national plans, even as overall enrollment declines.

What to Watch  

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, 2026, while Montana plans to begin implementation on July 1, 2026. With additional federal guidance still emerging, most other states are working toward compliance ahead of January 2027 deadlines. In expansion states, policymakers retain authority to tighten administrative processes, alter optional benefits, or adjust provider payment levels—actions that may materially affect enrollment. 

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‑net systems. For managed care organizations, even modest enrollment changes can mask more significant shifts in risk profiles, geographic concentration, or service needs.

On April 10, 2026, the Centers for Medicare & Medicaid Services (CMS) released the proposed rule for the Fiscal Year 2027 Hospital Inpatient Prospective Payment System (IPPS) and Long-Term Care Hospital Prospective Payment System (LTCH PPS). The proposal combines a modest net increase in hospital payments with policy signals around quality reporting and mandatory episode-based payment models—most notably a proposed nationwide expansion of the Comprehensive Care for Joint Replacement (CJR) model. 

These proposed updates underscore CMS’s continued emphasis on value-based purchasing, episode accountability, and alignment across quality programs. In addition, CMS resurfaces ongoing debates with hospital stakeholders about the adequacy of Medicare payment updates amid rising costs and coverage disruptions. 

This article reviews several key provisions in the FY 2027 proposed rule. 

Hospital Payment Updates: Headline Increase Masks Net Impact 

Under the proposed rule, CMS would increase base IPPS and LTCH PPS payment rates by 2.4 percent in FY 2027. However, after accounting for proposed reductions to uncompensated care payments for disproportionate share hospitals (DSH) and changes in outlier payments for extraordinarily high-cost cases, CMS estimates the effective payment increase would be closer to 1.2 percent. 

In aggregate, CMS projects the proposed update would translate to approximately $1.4 billion in additional payments to acute care hospitals next year. Hospital industry groups—including the American Hospital Association (AHA) and the Federation of American Hospitals (FAH)—have pushed back, arguing that the proposed update does not sufficiently reflect medical inflation, workforce pressures, or anticipated growth in the uninsured population. 

These concerns reflect a long-standing dynamic in annual hospital payment rules: CMS seeking to balance statutory updates and budget neutrality constraints against the hospital industry’s concern that Medicare payments are lagging behind underlying costs. 

Quality Reporting and Program Alignment 

The proposed rule would also make notable updates to the Hospital Inpatient Quality Reporting (IQR) Program. CMS proposes adding three new quality measures to be phased in during 2029 and 2030, while modifying eight existing measures to include Medicare Advantage patients. CMS also proposes shortening the performance period for certain measures from three years to two—a change designed to accelerate feedback and better align measures across programs. 

These changes continue CMS’s broader effort to harmonize quality measurement across Medicare payment and value-based programs, reduce reporting lag, and incorporate a more comprehensive view of patient populations. 

Updates to Mandatory TEAM Model 

CMS also proposes several updates to the Transforming Episode Accountability Model (TEAM), the mandatory episode-based payment model finalized last year. Key proposals include: 

• Expanding the list of MS-DRGs included in the spinal fusion episode 
• Aligning TEAM quality measurement performance periods with the IQR Program 
• Making targeted technical refinements to payment methodology 

In addition, CMS is seeking stakeholder feedback on whether ambulatory surgery centers (ASCs) should participate in TEAM and whether participation should be voluntary for physician-owned hospitals, signaling potential future expansion or recalibration of the model. 

Proposed Expansion of Joint Replacement Bundles 

CMS proposes to expand the existing Comprehensive Care for Joint Replacement Expanded (CJR-X) Model nationwide beginning October 1, 2027. The agency also plans to make participation mandatory for most IPPS hospitals. 

CMS tested the original CJR model in 34 metropolitan areas between 2016 and 2024, generating improved patient outcomes and net Medicare savings, according to agency evaluations. CJR-X would become the fifth Center for Medicare and Medicaid Innovation model to meet the statutory criteria for nationwide expansion. 

Under CJR-X, hospitals performing lower extremity joint replacements would be accountable for the cost and quality of care for the initial procedure and most related spending during the subsequent 90 days. Although the overall structure mirrors the original CJR model, CMS proposes several important updates: 

• Expansion of episodes to include ankle replacements, in addition to hip and knee procedures 
• Adoption of a more robust risk adjustment methodology with significantly more variables, aligning closely with the TEAM model 
• Introduction of a 5 percent stop-loss policy for hospitals that serve higher proportions of dually eligible beneficiaries and certain smaller hospitals 

Participation would be mandatory for most IPPS hospitals, with exceptions for hospitals already participating in TEAM, which includes a lower extremity joint replacement episode; Maryland hospitals operating under global budgets; and hospitals not paid under both IPPS and the Outpatient Prospective Payment System, such as Critical Access Hospitals. 

Why It Matters 

The 2027 IPPS and LTCH PPS proposed rule reinforces several clear policy signals: 

• Pressure on hospital margins is likely to persist, as payment updates continue to trail hospital-reported cost growth. 
• Mandatory episode-based models remain central to CMS’s value-based strategy, with CJR-X representing a significant escalation in scope and scale. 
• Program alignment and MA inclusion are accelerating, with implications for hospital data systems, care coordination strategies, and reporting infrastructure. 

Hospitals and health systems will need to assess not only the near-term financial impact of the proposed payment updates, but also their readiness to accept expanded episode accountability and meet evolving quality measurement requirements. 

Comments on the proposed rule will shape final decisions regarding payment levels, quality program changes, and the scope of mandatory participation in CJR-X. Stakeholders will be watching closely to see whether CMS moderates its approach to mandatory models or doubles down on episode-based accountability as a cornerstone of Medicare payment reform. 

In parallel, CMS has released several other proposed payment rules this month, including those that would affect skilled nursing facilities, hospice providers, inpatient rehabilitation facilities, and inpatient psychiatric facilities. For these entities, CMS generally proposes payment updates of approximately 2.4 percent and 2.3 percent for inpatient psychiatric facilities. As part of its broader program integrity focus, CMS also has proposed new transparency measures for hospice providers; this follows recent enforcement actions related to fraudulent enrollment.
