Humana slumps on drop in quality ratings

Humana slumped more than 17% after a drop in rating for one of its major Medicare Advantage plans.

According to data from the Centers for Medicare and Medicaid Services, only around 1.6 million members, or 25%, are now enrolled in Humana’s Medicare Advantage plans with ratings of 4 stars or higher, a decline from 94% in 2024.

This drop is due primarily to the downgrade of its H5216 plan, which covers about 45% of Humana’s MA members. The plan’s rating fell from 4.5 stars in 2024 to 3.5 stars in 2025.

Medicare Advantage plans receive star ratings from CMS. A drop in ratings reduces a plan’s appeal to potential enrollees and can lead to lower bonus payments from the government.

Humana is the Louisville, Ky., health insurer.
