CMS Announces LEAD, the Next Evolution of ACO REACH

CMS has officially announced the new LEAD (Long-term Enhanced ACO Design) model, marking the next evolution of ACO REACH and accountable care in Medicare.

LEAD is a population-based model designed to strengthen long-term accountability for cost, quality, and care coordination across aligned beneficiaries. Some notable aspects of LEAD are:

• Continued CMS support for providers through flexible, capitated population-based payments that encourage team-based care delivery and support downstream value-based care arrangements.

• The introduction of CMS-Administered Care Arrangements (CARAs), which create a voluntary, CMS-administered pathway for ACOs to enter episode-based, two-sided risk arrangements with medical specialists.

• Emphasis on improving the integration of Medicare and Medicaid services for dual eligible populations through enhanced data sharing and coordination.

• Incentives and reduced barriers for providers serving rural and other underserved populations, expanding access to value-based care participation.

Model timeline: CMS has announced LEAD as a long-term model, with a planned 10-year duration beginning in 2027. CMS is expected to release additional model details and the formal application period in early 2026, giving ACOs and specialists limited time to assess readiness, align partners, and prepare for participation.

Who can participate: LEAD is open to ACOs and similar risk-bearing organizations with the capability to manage population health, quality performance, and financial accountability for attributed Medicare beneficiaries. Participation in CARAs is voluntary and extends to medical specialists who are not part of the ACO, enabling broader alignment across the care continuum.

Payment and risk mechanisms: LEAD uses capitated payments and offers two risk tracks. Under the global risk track, participants are eligible to receive up to 100% of generated savings and are liable for up to 100% of total losses relative to their established performance benchmark. Under the professional risk track, participants are eligible to receive up to 50% of the total savings and are liable for up to 50% of total losses relative to their performance year benchmark.

Specialty care integration: CARAs complement this structure by introducing episode-based accountability for specific services or procedures, aligning incentives where specialists have the greatest impact. CARAs extend this two-sided risk framework to participating specialists within defined episodes, creating clearer accountability while keeping risk bounded and transparent. Together, LEAD and CARAs reinforce a win-win model for ACO–specialist partnerships, improving alignment, strengthening care coordination, and supporting better outcomes under value-based care.

Cedar Gate has deep experience enabling ACOs participating in value-based care arrangements through integrated data, analytics, care management, and payment technology. The unified platform delivers advanced analytics powered by NCQA-recognized HEDIS quality measures, as well as HCC risk calculation methodologies. Combined with care management capabilities and capitation payment technology, Cedar Gate supports robust financial and funds flow analysis and the end-to-end administration of capitated arrangements under a single provider identifier. All capabilities are integrated through a common data lake, reducing latency between data, insights, and action while minimizing data inconsistencies and performance variation.

Building on this platform foundation, Cedar Gate also brings extensive experience designing, modeling, implementing, operating, and optimizing bundled payment arrangements. With proven capabilities across episode analytics, financial modeling, performance measurement, and operational execution, Cedar Gate is well positioned to support organizations as they adopt and scale the episode-based components of the LEAD model.
