Arizona sues MultiPlan, major insurers, alleging a ‘cartel’ that underpaid doctors and hospitals

Arizona Attorney General Kris Mayes filed a lawsuit against MultiPlan (now Claritev) and major insurers like Aetna, Cigna, and UnitedHealthcare, alleging they colluded to use a proprietary algorithm to set lower rates for out-of-network care, underpaying providers and shifting costs to patients. The lawsuit claims this violated Arizona’s anti-trust and consumer fraud laws, while MultiPlan denied the allegations, stating the case is 'without merit.'
