Two of Sacramento's biggest health care players paid a combined $2.3 million to the federal government to settle allegations that 61 of their hospitals double-billed Medicare for therapies and services, U.S. Department of Justice officials announced Wednesday. Catholic Healthcare West paid more than $875,000 and Sutter Health nearly twice that ? more than $1.43 million ? for alleged duplicate charges for infusion therapies and treatments to break up kidney and bladder stones, in what Lauren Horwood, a spokeswoman in the Sacramento U.S. attorney's office, called "a significant settlement."
