Federal authorities say two California health care operators have paid $2.3 million to settle claims that they overcharged the government for medical services.
The U.S. Attorney's Office in Sacramento said Wednesday that Sutter Health Association has paid more than $1.4 million to the United States and Catholic Healthcare West paid more than $875,000.
Federal Department of Health and Human Services auditors found the two improperly billed the government more than once for the same medical procedures.
Catholic Healthcare West is the nation's fifth largest hospital provider, and the largest in California. The 36 affiliate hospitals involved in the overbilling are located in California, Nevada, and Arizona. The 25 Sutter Health Association hospitals are all in Northern California.
Authorities say the hospitals cooperated. Hospital officials could not immediately comment Wednesday.
