CMS Updates the ACO REACH Model for 2026: What It Means for Value-Based Care Leaders

CMS has released updates to the Accountable Care Organization Realizing Equity, Access, and Community Health (ACO REACH) model for Performance Year (PY) 2026, reinforcing their long-term commitment to value-based care while refining financial accountability and sustainability for participating organizations.

According to CMS, the PY 2026 updates are informed by early performance results and are intended to “strengthen the model test and improve long-term viability” of ACO REACH (CMS Quick Reference). For ACOs, these changes signal a clear expectation: greater precision in managing risk, cost, and outcomes across the full care continuum — especially post-acute care.

What’s Changing in ACO REACH for Performance Year 2026

CMS’s PY 2026 update introduces several refinements aimed at stabilizing financial performance while maintaining strong incentives for high-quality, coordinated care.

Key changes include:

• Adjustments to risk score growth caps, particularly affecting organizations caring for complex and high-need populations, to limit excessive benchmark inflation (CMS PY 2026 FAQs)
• Refinements to financial benchmarking and risk corridors, narrowing upside and downside variability to promote predictability (CMS Innovation Insight)
• Continued emphasis on total cost of care and quality performance, reinforcing accountability across inpatient, outpatient, and post-acute settings (ACO REACH Model Overview)

Industry analyses note that these changes reflect CMS’s effort to balance innovation with guardrails that reduce volatility for participating organizations (Milliman analysis).

Why the 2026 Updates Matter for ACOs and Post-Acute Care

As financial risk becomes more tightly managed under ACO REACH, post-acute care performance plays an increasingly central role in determining success.

Independent analyses have highlighted that tighter risk score caps and benchmark adjustments place greater pressure on ACOs to actively manage:

• Avoidable hospital readmissions
• Length of stay and utilization in skilled nursing and other post-acute settings
• Care transitions for high-risk beneficiaries

In this environment, post-acute care can no longer be treated as a downstream afterthought — it is a primary driver of both cost and quality outcomes under ACO REACH.

Where Cascala Fits in the ACO REACH 2026 Environment

As ACO REACH evolves, Cascala supports value-based care organizations by enabling data-driven clinical decision-making at the point of care transition for patients transitioning into post-acute settings.

With tighter benchmarks and reduced margin for error, ACOs need actionable insight — not retrospective data. Cascala helps organizations:

• Identify high-risk patients earlier, supporting proactive care planning aligned with ACO financial accountability
• Improve post-acute coordination, using real-time insights to guide decisions that impact total cost of care
• Reduce avoidable utilization, including preventable readmissions and unnecessary extended stays
• Support clinicians and care teams with intelligence that integrates into existing workflows

Looking Ahead: ACO REACH Signals the Direction of Value-Based Care

CMS has confirmed that PY 2026 is the final scheduled performance year under the current ACO REACH design, making these updates particularly consequential for participating organizations (CMS ACO REACH Overview).

The message from CMS is consistent: value-based models will continue to reward organizations that can connect data, clinical action, and accountability across settings, including post-acute care.

For Cascala, the ACO REACH PY 2026 updates underscore an ongoing opportunity to help ACOs translate evolving policy into practical, patient-centered execution — improving outcomes while managing risk in an increasingly demanding value-based care landscape.
