UnitedHealth Group (NYSE: UNH) is the parent company of various other health services organizations and health insurers. With $94.2 billion in revenue in 2010, UNH is the second-largest publicly traded health insurance company in the United States.^[1] As such, it has significant scale advantages that extend across its major product lines, allowing it to attract new member hospitals as well as negotiate for lower prices.

United uses the data to evaluate the effectiveness of its doctors and hospitals; the company also sells the information to other health industry professionals.
