Medicare Advantage enrollment grew by about 484,000 lives during the Open Enrollment Period (OEP), according to CMS’s April data release. As in the Annual Election Period (AEP), OEP gains were heavily concentrated among the five largest MA insurers (UnitedHealthcare, Humana Inc., CVS Health Corp.’s Aetna, Anthem, Inc. and Kaiser Foundation Health Plan’s California subsidiary), which saw 71.8% of the overall membership growth during the OEP. But smaller plans also made headway, with some performing nearly as well in the OEP as they did in the AEP. Three plans that saw membership losses during the AEP (Kaiser’s mid-Atlantic subsidiary, Blue Cross Blue Shield of Arizona and InnovaCare Health Solutions) were able to improve their performance in the OEP. See the top 20 OEP performers, plus their AEP results below.
