NOTES. p < 0.001 for differences between disenrollees and fee-for-service stayers with respect to average risk scores and all types of service. Disenrollees went from Medicare Advantage (MA) to fee-for-service (FFS). Switches from one MA plan to another were not counted as MA disenrollments. Medicare payments exclude payments for hospice care and were measured over the six months following dates of disenrollment or pseudo-disenrollment. Data for FFS stayers were weighted to match the distribution of disenrollees across states and counties of residence. All data were weighted by the number of months alive and in FFS during the six months following disenrollment or pseudo-disenrollment.
