More and more payors are instituting rating systems for their participating physicians and at least one state attorney general has taken issue with the practice. According to a recent article on CNNMoney.com, the New York Attorney General has threatened an injunction against United Healthcare if it implements a physician rating system in New York. The Attorney General has apparently cited a number of concerns with the rating system, including that the rating data may be faulty and that patients may choose doctors based on cost rather than quality.
