Health insurer UnitedHealth Group used aggressive tactics to gather diagnoses that can boost Medicare Advantage payments, the Wall Street Journal reported on Monday, citing a U.S. Senate committee investigating the company's practices.
Shares of the company were down 1.4% to $339.42 in premarket trading.
The Senate report makes no formal recommendations and does not accuse UnitedHealth of wrongdoing, the Journal reported.
The company did not immediately respond to a Reuters request for comment.
