Washington’s hospital lobby lost an effort to stop the Trump administration from cutting payments under a drug discount program for hospitals that cover low-income patients.

The U.S. Court of Appeals for the District of Columbia upheld a lower court ruling that struck down a lawsuit from the American Hospital Association and other hospital groups on the payment cuts to a program called 340B. The decision issued Tuesday is a major win for the Trump administration and the pharmaceutical lobby that had been pressing for changes to the program.
