This week, our In Focus reviews the Medicare Advantage (MA) and Part D landscape files and quality performance data for the 2020 plan year from the Centers for Medicare & Medicaid Services (CMS). Data on MA and Part D offerings include premiums and benefit design, as well as Star Ratings for each MA contract. This year’s release signals continued growth for the MA program in 2020. The total number of MA plans increased by 403 offerings to 3,144, up from 2,741 in 2019, the highest number since inception of the program. Notably, growth appears to be occurring in parts of the country with existing market saturation, as many MA organizations are offering new plans in states with MA enrollment levels of 30 percent or higher. There is also significant growth in the number of Dual Eligible Special Needs Plans (D-SNPs) offered by MA organizations, particularly among top MA sponsors Humana and CVS (Aetna).
