Humana said on Thursday it has about 20% of its members currently enrolled in Medicare Advantage plans rated 4 stars and above for 2026, based on preliminary data.

Shares of the health insurer were up 3% in midday trading.

The preliminary star ratings data was inadvertently accessible on the Centers for Medicare and Medicaid Services’ Plan Finder for a period of time on Wednesday, Humana said in a regulatory filing.

CMS, a part of the U.S. Department of Health and Human Services, did not immediately respond to a Reuters request for comment on the timing of the release of ratings.

The agency issues star ratings for Medicare Advantage plans, which cover Americans aged 65 years or older, from one to five, with five being the highest-performing, to help beneficiaries choose among them.

Humana said it has about 1.2 million, or 20%, of its members currently enrolled in high-rated Medicare Advantage plans for 2026, with an average star rating of 3.61, consistent with its 2025 average star rating.

The company also has 14% of its members in 4.5-star plans in 2026, up from 3% in 2025, it said in the filing.
