Medicare Advantage enrollment grew by about 257,000 lives during the 2021 Open Enrollment Period (OEP), according to CMS’s May data release and AIS’s Directory of Health Plans. As in the Annual Election Period (AEP), UnitedHealthcare dominated, holding about 32% of the overall OEP gains. Still, there were some shakeups among the other largest MA payers. In terms of membership gains, Centene Corp. (including enrollment from its WellCare brands) jumped from the No. 4 spot in the AEP to the No. 2 spot in the OEP, while Kaiser Permanente rose from No. 7 to No. 5. Cigna Corp., meanwhile, lost much of its momentum from the AEP, dropping from No. 9 to No. 20. See the top 25 OEP performers in the chart below.
