For years, care management enrollment (CCM, RTM, etc.) has been slow and inefficient, typically requiring dedicated Care Advocates (CAs). Even when busy physicians refer patients during visits, they rarely have time to walk through a Medicare-compliant informed consent script. And hiring and scaling CAs doesn’t solve the problem. They spend their days working call queues, navigating compliance requirements, and chasing missed connections—constrained by limited hours and patient availability.
The result: national enrollment conversion rates hover around just 15%. Most practices accept this limited this scale. CircleLink doesn't.
CircleLink's SphereCM platform pairs dedicated RNs with supervised agentic AI to extend the reach of care teams across CCM, RPM, RTM, and APCM programs. At the front of that pipeline sits one of SphereCM's most impactful capabilities: the AI Care Management Enroller. This month, across three of our clinic partners, we ran a direct comparison between the AI Enroller and our experienced human CA team. The results confirm what we've seen building in the data for months: the AI has reached parity with human enrollers on conversion rate. And unlike a human team, it never sleeps, never hits capacity, and never needs management-orientation or other oversight.
Here's what the March 1st to March 23rd, 2026 enrollment data showed across the three clinic partners in this trial:
At our largest partner clinic — the most statistically meaningful comparison — the AI converted 59.4% of processed patients versus 62.1% for human CAs. The gap is real, but it is narrowing fast. And critically, the AI was handling nearly double the patient volume.
Conversion rate is an important metric for CCM / Care Management. But for practice executives managing programs at scale, what matters more is: scalability, ease-of-use and compliance. SphereCM's AI Enroller shines on all these parameters:
Results like these don't happen by accident. Before a single live patient call was made, CircleLink spent months in a rigorous development and quality assurance process that many AI vendors skip.
The team ran tens of thousands of simulated calls, using AI-generated patient personas, that covered the full spectrum of real-world patient behavior. Cooperative patients. Confused patients. Skeptical patients. And deliberately hostile ones.
Each iteration refined the agent's prompt architecture: how it introduces itself, how it references the patient's specific provider and recent visit, how it handles objections, when it de-escalates, and how it maintains accuracy under pressure. The goal wasn't just a script that worked in ideal conditions; it was an agent that could handle anything a real patient might throw at it, without losing composure, accuracy, or compliance.
The result is an enrollment agent that stays perfectly composed no matter how the conversation goes. It's never flustered, never off-message, never out of compliance. Human CAs have good days and bad days. The SphereCM AI Enroller performs at its best on every single call.
The AI Enroller doesn't operate in isolation. It's the entry point into SphereCM: CircleLink's full care management platform that pairs agentic AI with 100% RN care coaches to handle the entire care management workflow: RN care coaching, outreach/patient engagement, surveys, documentation, and billing. After more than 400,000 patient encounters, SphereCM has demonstrated a 31% total cost reduction while sustaining >99% billing accuracy and consistent audit-ready compliance.
For organizations that want to start with enrollment and expand from there, the AI Enroller is available as a standalone capability. But the practices seeing the greatest impact are those using it as the first step in a fully integrated SphereCM program — turning enrollment momentum directly into reimbursable care management activity.
The convergence we're seeing in March 2026 isn't the ceiling — it's the floor. The AI Enroller improves with every batch, and it feeds a platform that multiplies its impact across the full care management cycle. The calculus for clinics and health systems is becoming clear: same enrollment outcomes, unlimited scale, no hiring dependency — and a platform built to take it from there.
SphereCM integrates seamlessly with all major EHRs — like Epic, Cerner, athena, eCW, and Veradigm — with near zero IT lift required.
