GE Healthcare has paid the U.S. $30 million, plus interest, to settle allegations that a company it acquired in 2004, Amersham Health, had violated the False Claims Act by causing Medicare to overpay for Myoview, a radiopharmaceutical used in certain cardiac diagnostic imaging procedures, according to the U.S. Department of Justice.

A West Palm Beach, Fla. radiology practice will pay the U.S. government $3 million to settle charges that it submitted false Medicare claims as part of illegal service agreements with referring physicians. A pair of radiologists who initiated the investigation will receive a $600,000 settlement.
