New York Attorney General Andrew Cuomo has announced that two additional regional insurers have agreed to pay more than $600,000 to help establish a new independent database to determine the rate they pay doctors and hospitals out of their network. Cuomo said Independent Health, which insures about 365,000 people in western New York, has agreed to pay $475,000, while HealthNow New York Inc., which insurers about 800,000 people in the state, will contribute $212,500.
