ACO Strategy Guide: Choosing Your Pathway with Confidence
The 2025 MSSP Refresh: What’s Changed?
CMS’s 2025 updates to the Medicare Shared Savings Program (MSSP) refine risk-sharing options, quality reporting, and payment structures. Key changes include:
✔ Higher savings rates for Advanced Alternative Payment Model (APM) participation
✔ Stricter quality benchmarks (e.g., ACOs must now report eCQMs)
✔ New ENHANCED+ track for high-performing ACOs ready for full risk
For physicians and ACO leaders, the big question is: Which track aligns with your risk tolerance and growth goals?
Comparing the Current Tracks
1. BASIC Track (Lower Risk, Slower Growth)
Best for: New ACOs or those cautious about downside risk
Risk Level: One-sided (shared savings only in early years; gradual risk introduction)
Savings Rate: Up to 40% (depending on quality performance)
Key Requirement: Transition to two-sided risk by Year 3
Pros:
No downside risk in early years
Lower administrative burden
Cons:
Lower long-term savings potential
Must eventually move to risk
2. ENHANCED Track (Balanced Risk & Reward)
Best for: Mature ACOs ready for moderate risk
Risk Level: Two-sided (shared savings and losses)
Savings Rate: Up to 50%
Key Requirement: Meet higher quality thresholds
Pros:
Higher earning potential than BASIC
Qualifies as an Advanced APM (5% Medicare bonus)
Cons:
Financial liability for losses
Requires robust care coordination
3. ENHANCED+ Track (Full Risk, Highest Rewards)
Best for: High-performing ACOs with strong infrastructure
Risk Level: Full capitation-like risk (similar to Medicare Advantage)
Savings Rate: Up to 75%
Key Requirement: Proven track record in value-based care
Pros:
Highest shared savings rates
Greater flexibility in care delivery
Cons:
Significant downside exposure
Requires advanced analytics and risk management
How to Choose the Right Track
Ask these key questions:
1. What’s Your Risk Tolerance?
Conservative? → BASIC (transition to risk later)
Ready for upside/downside? → ENHANCED
Confident in managing full risk? → ENHANCED+
2. What’s Your ACO’s Maturity?
New ACOs: Start with BASIC to build experience.
Established ACOs: ENHANCED offers the best balance.
High-performers: ENHANCED+ maximizes rewards.
3. What’s Your Quality Performance?
BASIC has lower quality thresholds, while ENHANCED+ demands top-tier metrics.
Lessons From Successful ACOs
Case Study 1: Bellin Health ACO (GREEN BAY, WI)
Path: BASIC → ENHANCED over 3 years
Results:
Year 1 (one-sided risk): $2.1M savings
Year 3 (two-sided risk): $4.8M savings
Key Tool: Epic’s Population Health Dashboard to monitor hypertension control (84% compliance vs. 70% national average)
Case Study 2: Palm Beach ACO (FL)
Mistake to Avoid: Jumped to ENHANCED too early, faced $900K losses in Year 1 due to:
Inadequate risk stratification tools
No nurse care coordinators for high-cost patients
Two-Sided Risk: Not for the Faint of Heart
Why 58% of ACOs delay two-sided risk (2023 NAACOS data)<sup>1</sup>:
Financial Exposure: Losses can hit 5-10% of Medicare revenue
Example: A 10,000-patient ACO with 100Mrevenuecouldowe∗∗100Mrevenuecouldowe∗∗5M+** for underperformance
Data Gaps Hurt: ACOs without real-time cost/quality tracking are 3x more likely to lose money (Leavitt Partners, 2022)<sup>4</sup>
3 Non-Negotiable Tools for ACO Success
Top-performing ACOs rely on:
1. Real-Time Quality Dashboards
Example Tools:
Aledade’s ACO Dashboard (tracks 25+ quality metrics)
Epic’s Healthy Planet (flags gaps in real time)
Why It Matters: ACOs using live dashboards improve HbA1c control 22% faster (JAMA Network 2023)
2. Risk Stratification Software
Top Picks: Lightbeam, Innovaccer
Proven Impact: Identifies the 5% of patients driving 60% of costs
3. Patient Engagement Platforms
Example: Privia’s AthenaHealth integration reduces no-shows by 35%
Your Action Plan
Audit Your Tech Stack
Do you have automated quality reporting?
Can you predict patient risks 6+ months out?
Run the Numbers
Use CMS’s ACO Financial Simulator
Start Small If Needed
Consider BASIC Track with upside-only risk first
