As of CMS’s May 2020 data release, the top 10 Medicare Advantage Prescription Drug payers combined enrolled 76.3% of the national MA-PD market, with 81.4% of their combined 18.7 million lives enrolled in a contract with an overall star rating of 4 stars or higher. Kaiser Permanente’s seven regional insurance subsidiaries remain on top of the pack, with 94.3% of their members enrolled in a 5-star contract. Only one of the top 10 payers, WellCare Health Plans Inc., had any of its contracts score below a 3 overall. See the full ratings and enrollment distribution for the top 10 MA-PD insurers below.

NOTES: The above lives distribution does not include enrollment data from contracts that were too new to be rated, or did not have enough data available to measure a star rating. Centene Corp. completed its acquisition of WellCare Health Plans, Inc. in January 2020.
