The Obamacare saga has created a new alliance among larger employers, according to the Wall Street Journal.

Twenty major companies including American Express Co.Macys Inc. and Verizon Communications Inc.are banding together to use their collective data and market power in a bid to hold down the cost of providing workers with health-care benefits. 

The newly formed alliance of companies, which cover about four million people among them, plan to share information about members employee health spending and outcomes, with an eye toward using findings to change how they contract for care. Ultimately, some members say, they could even form a purchasing cooperative to negotiate for lower prices, or try to change their relationships with insurance administrators and drug-benefit managers.
