For health plan leaders, growth is a strategic imperative. Yet managed care organizations (MCOs) cannot scale effectively when 10% to 25% of their members disenroll each year. This harsh reality cuts across all lines of business, with Medicare and Medicaid plans hit especially hard. Even more frustrating is that many organizations lack visibility into why their members leave, making it difficult to act until it’s too late. The good news: 30% to 50% of member churn is voluntary and preventable. But health plan leaders need to know where to look. Enter churn analytics. Health plans that capture and use churn data can re-engage at-risk members, drive satisfaction, and protect long-term growth. Here’s what’s at stake — and how to move from being a reactive organization to a proactive one.
