Despite Top-Level Decline, Tukey-Impacted Star Ratings Suggest Mostly Stable Performance

  • Oct 19, 2023

    Only 42% of Medicare Advantage Prescription Drug (MA-PD) contracts that will be offered in 2024 achieved an overall rating of 4 stars or higher, compared with approximately 51% of contracts in 2023, according to the latest Medicare Part C and Part D Star Ratings data. Weighted by enrollment, the average MA-PD Star Rating fell from 4.14 for 2023 to 4.04, with approximately 74% of MA-PD enrollees estimated to be enrolled in contracts that achieved 4 or more stars for 2024, compared with 72% for 2023, CMS reported on Oct. 13.

    Those changes were largely expected due to the application of the new Tukey outlier deletion methodology, which was used in determining the cut points for measures not directly related to member experience and largely achieved CMS’s stated goal of infusing more “predictability and stability” into the Star Ratings.
