The Department of Justice’s Antitrust Division today announced a settlement that would allow CVS Health and Aetna to proceed with their proposed merger if Aetna divests its Medicare Part D prescription drug plans to WellCare. The settlement was filed in federal court as part of a civil antitrust lawsuit brought by the department and state attorneys general from California, Florida, Hawaii, Mississippi and Washington over competitive concerns with the merger. If approved by the court, the settlement would resolve those concerns, the agency said.
