UnitedHealth Group, Optum, Inc., and Change Healthcare

Following a ransomware attack on February 21, the extent of the impact on Change Healthcare, providers, and patients is being evaluated. Class action lawsuits filed against UnitedHealth Group, Optum, Inc., and Change Healthcare are converging in Nashville's federal court, as proposed by Change Healthcare to streamline proceedings. Healthcare providers faced difficulties in checking insurance eligibility and processing prior authorization requests, disrupting patient care. Restoration efforts for Change Healthcare's products and services were still ongoing as of March 31.
