Elevance Health (ELV) rose 0.87% on 2025-08-19, with a trading volume of $760 million, ranking 110th in the market. The stock’s movement followed a legal setback involving its Medicare Advantage plans.
A Texas federal judge dismissed Elevance’s lawsuit challenging the U.S. Department of Health and Human Services’ (HHS) 2025 Medicare star ratings. The company argued improper rounding of its 3.749565 score to 3.5 stars cost it at least $375 million in bonus payments tied to higher-tier ratings.
