The Justice Department is investigating whether the renowned NewYork-Presbyterian health system violated antitrust laws through hidden deals with insurance companies that kept hospital prices high, according to a subpoena reviewed by The New York Times.

The civil investigation is examining whether NewYork-Presbyterian persuaded insurance companies to agree to conditions that insulated the hospital system from competition — which would enable it to charge more for common procedures with little worry about losing patients.
