Morningstar analyst Julie Utterback said "CVS and Humana also have ambitions in caregiving, so this investigation may have implications for those two ... in particular, if the investigation eventually spreads". WSJ reported that investigators have asked industry representatives about issues including certain relationships between the company's UnitedHealthcare insurance unit and its Optum health services arm, which owns physician groups, among other assets. Separately, Change Healthcare said in an update on its status page on Wednesday that disruptions from the hack incident were expected to last at least through the day. A number of pharmacy chains, including CVS Health, have said the outage had impacted their businesses. (Reporting by Christy Santhosh in Bengaluru; Editing by Sriraj Kalluvila and Shinjini Ganguli)
