In re: Aetna UCR Litigation, MDL No. 2020: Hartford-based Aetna Inc. will pay as much as $120 million to settle a federal class action in which plaintiffs alleged that the insurer provided inadequate payments to consumers who visited out-of-network medical providers and to the doctors who treated them.

The lawsuit was pending in U.S. District Court in New Jersey. The settlement, which may not become official until sometime next year, must be approved by federal Judge Stanley Chesler in Newark, N.J.
