UnitedHealth stock slides after Senate report targets Medicare Advantage coding as UNH earnings loom
New York, January 13, 2026, 12:11 EST — Regular session Shares of UnitedHealth Group Incorporated dropped roughly 1.3%, hitting $336.10 by midday Tuesday. The move came after a Senate Judiciary Committee report criticized the insurer’s Medicare Advantage risk-adjustment coding. Senator Chuck Grassley, who chairs the panel, claimed the company “appears to be gaming the system” related to payments for sicker patients.
