The Medicare Advantage retention gap: Turning member experience into a growth strategy 

Growth in Medicare Advantage has become increasingly difficult to sustain. Acquisition costs are rising, competition is intensifying, and members are more willing than ever to switch plans in search of better value. A study found that 15.6% of Medicare Advantage members changed plans within one year after enrollment, and 49.2% changed plans after five years.  

For many organizations, the traditional growth model of driving enrollment while offsetting ongoing member losses is no longer sustainable. 

Retention is the missing lever in Medicare Advantage growth 

Most Medicare Advantage strategies still prioritize enrollment as the primary driver of growth. But this approach overlooks a critical reality: retention has a greater impact on long-term performance than acquisition alone. 

When members stay longer: 

• Lifetime value increases  

• Acquisition costs are spread over a longer member lifetime  

• Care management programs become more effective  

• Revenue becomes more predictable  

When members leave, those advantages disappear, forcing plans to continuously replace lost value. Despite its importance, retention is often managed as a downstream outcome, measured after the fact rather than treated as an active, ongoing strategic objective.  

This is the Medicare Advantage retention gap. For many plans, it’s the difference between growing and standing still. 

What’s really driving member churn 

Member churn is the result of how members experience their health plan over time. Three factors consistently shape that experience and determine whether members stay or leave: 

Member experience (CAHPS performance): Consumer Assessment of Healthcare Providers and Systems (CAHPS) measures are more than survey scores. They reflect how members perceive access, communication, and overall satisfaction with their health plan. Poor experiences, whether from difficulty navigating benefits, limited provider access, or lack of engagement, erode trust and increase the likelihood of disenrollment. 

Star Ratings performance: Higher-rated plans attract and retain members by signaling quality. These higher ratings also unlock additional revenue that can be reinvested into benefits and services. Medicare Advantage plans that fall below the 4-Star threshold not only lose bonus payments but often struggle to deliver competitive member experiences as a result.  

Benefit design and perceived value: Members evaluate whether their plan meets their needs. Benefits, affordability, and ease of use all contribute to perceived value. When benefits fall short or feel disconnected from member needs, retention suffers. 

While these three factors are interconnected, most organizations manage them in isolation. 

Why most plans struggle to improve retention 

Critical insights into retention drivers are spread across: 

• CAHPS and member feedback systems  

• Clinical and quality performance data  

• Claims and utilization data  

• Financial and benefit design models  

Without a unified view, leaders are left with fragmented data: 

• Experience teams track satisfaction  

• Quality teams focus on Star Ratings and HEDIS®  

• Finance evaluates cost and margin  

• Growth leaders monitor enrollment and churn  

No single function has a complete picture of what’s driving retention or how to improve it effectively. The result is a reactive approach: identifying churn after it happens, then adjusting strategies too late to change the outcome. 

How leading Medicare Advantage plans turn retention into a growth engine 

High-performing plans are taking a different approach. They treat retention as a core growth strategy, not a secondary metric, and they operationalize it accordingly. 

This starts with a shift in how retention is understood and managed: 

• From lagging indicator to leading insight: Identifying members at risk of churn before they leave  

• From siloed metrics to connected drivers: Linking CAHPS, Star Ratings, utilization, and benefits to understand what truly impacts member decisions  

• From broad programs to targeted action: Prioritizing interventions based on which members and which actions will drive the greatest impact  

• From periodic analysis to continuous optimization: Monitoring retention risk and performance throughout the year, not just during enrollment cycles  

These shifts transform retention from a reporting exercise into a scalable growth lever. 

The role of data in closing the retention gap 

Executing this strategy requires more than intuition. It requires a complete, connected view of the member. MedeAnalytics Medicare Advantage Insights enables health plans to unify clinical, claims, financial, and member experience data into a single, trusted platform, creating a comprehensive view of each member and their journey.  

With this foundation, leaders can: 

• Identify members most at risk of disenrollment  

• Understand the combination of factors driving dissatisfaction or disengagement  

• Align benefit design, care programs, and outreach strategies to member needs  

• Measure how improvements in experience and quality translate into retention and revenue  

MedeAnalytics operationalizes these insights by embedding them into workflows, allowing teams to take scalable action and track results over time.  

From retention gap to sustainable growth 

The economics of Medicare Advantage are shifting. Plans that rely solely on acquisition will face increasing cost pressure, ongoing churn, and greater volatility. Those that invest in retention will build more stable, predictable, and profitable growth.  

The opportunity for Medicare Advantage leaders is clear: turn retention from an outcome into a deliberate growth strategy. The plans that win in Medicare Advantage won’t just be the ones that enroll more members. They’ll be the ones that give members a reason to stay.
