Medicare has begun punishing 721 hospitals with high rates of infections and other medical errors, cutting payments to half of the nation's major teaching hospitals and many institutions that are marquee names. Intermountain Medical Center in Utah, Ronald Reagan UCLA Medical Center in Los Angeles, the Cleveland Clinic, Geisinger Medical Center in Pennsylvania, Brigham and Women's Hospital in Boston, NYU Langone Medical Center and Northwestern Memorial Hospital in Chicago are all being docked 1 percent of their Medicare payments through next September, federal records show. In total, hospitals will forfeit $373 million, Medicare estimates.
