Health insurer Anthem on Monday filed a lawsuit against Express Scripts, the St. Louis-based pharmacy benefits manager, to recoup billions of dollars lost to what Anthem says were excessive drug payments.
Anthem is seeking about $15 billion in the suit, which marks the latest development in an ongoing dispute between Express Scripts, the nation’s largest pharmacy benefits manager, and Anthem, its biggest client.
In the lawsuit, Anthem says its repeated attempts to negotiate better drug prices with Express Scripts were either rejected or ignored.
Despite the legal action and Anthem’s threat to end the companies’ relationship, incoming Express Scripts CEO Tim Wentworth said his company intends to retain its largest customer.
“We don’t intend to lose Anthem,” said Wentworth, who takes over in May for current CEO George Paz. “We’ll get through this.”
