Another health insurer has agreed to contribute to the effort to start a competitor to UnitedHealth Group Inc.'s Ingenix health care price data service.
Guardian Life Insurance Company of America, New York, has resolved the concerns of New York Attorney Andrew Cuomo by agreeing to stop using Ingenix data to price health plan members' out-of-network physician claims, and also to contribute $500,000 to an effort to start a new, nonprofit physician rate database.
