The CMS Innovation Center's new Long-term Enhanced ACO Design (LEAD) model is the most significant structural update to Medicare accountable care in years. Its goals are practical: bring more providers into ACOs (including smaller, rural, and independent practices that previous models left behind), fix benchmarking methods that penalized high performers, and improve care for high-needs and dually eligible patients who have historically been underserved by value-based arrangements.
It's a ten-year model precisely because CMS recognizes that real care transformation takes time. And it creates real new demands on the organizations that participate.
What LEAD is asking of providers
Launching January 1, 2027, LEAD is the successor to ACO REACH and the longest-running ACO model CMS has ever tested. Its ten-year performance period, no-rebasing benchmark design, and expanded support for high-needs and dually eligible patients represent a serious, durable bet on value-based care.
But the model's ambition comes with real demands on care teams. To succeed under LEAD, ACOs will need to:
- Surface and act on complex patient data before problems escalate
- Demonstrate measurable quality improvement on a targeted set of clinical measures, including glycemic control and blood pressure management
- Proactively engage high-needs and dually eligible patients who have historically fallen through the cracks
- Build tighter coordination loops between primary care and specialists through new episode-based arrangements (CARA)
- Develop individualized Prevention and Quality Plans tailored to their specific patient population — a mandatory requirement from PY2027
These demands go beyond admin to influence clinical workflows. And they require clinical AI that works the way physicians actually work.
What this means for clinical infrastructure
This is where Navina fits in. Our platform transforms fragmented patient data into clear, actionable clinical insights, surfacing what matters, when it matters, so care teams can close gaps and manage risk.
The workflows LEAD rewards — proactive gap closure, chronic disease management, risk stratification for complex populations — are precisely the workflows Navina is designed to support. Under LEAD's quality framework, two new eCQMs (diabetes glycemic status and blood pressure control) sit at the center of performance alongside five measures carried over from ACO REACH. Importantly, eCQM reporting starts as optional and phases in gradually (pay-for-reporting in PY3–4, pay-for-performance from PY5 onward), giving ACOs time to build the infrastructure to perform, not just report. The time to build that infrastructure is now, not in year three.
And as ACOs build tighter relationships with specialists through CARA, which for the first time lets ACOs contract directly with specialists for specific quality and cost outcomes, the need for shared, longitudinal patient context only grows. Navina streamlines workflows to provide every member of the care team, primary care and specialist alike, the same clear picture of who each patient is and what they need.
It's also worth noting that CMS has built a Tech Enabler Initiative directly into LEAD: a formal program to help ACOs adopt AI and high-value technology, with care navigation and chronic condition management among the priority use cases. And starting in 2028, LEAD will begin integrating AI-generated risk scores into its financial methodology, moving to full AI-inferred risk adjustment by 2031. AI is truly a core component of LEAD's architecture.
The application window is open — and short
The LEAD application portal opened March 31 and closes May 17, 2026. That's 47 days. LEAD's no-rebasing design means that ACOs who invest early in better care delivery will compound those gains over a decade. The organizations that build strong clinical AI infrastructure now will be best positioned to thrive under LEAD.
For organizations evaluating LEAD participation, now is the time to assess your clinical infrastructure, not just your financial readiness.
