Medicare Advantage enrollment grew 8.0% from September 2018 to September 2019, according to AIS’s Directory of Health Plans (see a complete month-by-month timeline below), continuing a trend of greater MA gains as more baby boomers, seeking more personalized benefits, age into Medicare. In advance of the Annual Election Period (AEP) starting on Oct. 15, CMS on Sept. 24 said it expects MA enrollment to reach new highs in 2020, growing about 10% to 24.4 million lives. Growth this past year was concentrated among the largest payers in the MA space, with the top five experiencing enrollment gains of about 16% on average year over year (see breakdown below). The big winner was Aetna Inc., which took on its largest-ever MA expansion in 2019, adding its offerings to more than 350 new counties. While still on top, market leader UnitedHealthcare’s post-AEP gains were smaller than the 400,000 to 450,000 members (excluding dual eligible Special Needs Plans) the company anticipated, instead adding only about 290,000 lives.

NOTE: All enrollment totals include dual eligible Special Needs Plans (D-SNPs) except where noted. AIS defines post-AEP enrollment as total MA membership as of February 2019.
