Medicare Advantage (MA) is becoming the dominant source of Medicare coverage. MA plans are paid capitated rates and have historically selectively enrolled healthier individuals. In response, Medicare has repeatedly recalibrated the risk-adjustment model. However, concerns still exist that MA plans may have access barriers (eg, restrictive clinician or hospital networks and utilization management) for enrollees with demanding health needs. We examined whether MA enrollees with more chronic conditions are more likely to disenroll over a recent 10-year period when MA enrollment grew rapidly.
