Based on preliminary 2025 Medicare Advantage (MA) Star Ratings data provided by the Centers for Medicare and Medicaid Services (CMS), which became available in CMS Plan Finder as of October 1, 2024, Humana Ihas approximately 1.6 million, or 25%, of its members currently enrolled in plans rated 4 stars and above for 2025, a reduction from 94% in 2024.

A significant driver of these results was contract H5216 decreasing to a 3.5-star rating from a 4.5-star rating in 2024. The decline in Stars performance for 2025 will impact Humana's quality bonus payments in 2026. 2025 Star rating details are expected to be formally released by CMS on or around October 10th.
