KANSAS CITY, MO. — A federal grand jury has indicted the owners of a Kansas City medical clinic on charges of health care fraud and filing false tax returns.

The U.S. Attorney’s office in Kansas City says 75-year-old Carol Ann Ryser and 67-year-old Michael Earl Ryser, both of Mission Hills, Kan., have been charged in an indictment returned Tuesday. The Rysers are charged with one count each of health care fraud and three counts of filing false tax returns.

The Rysers are married and co-own Health Centers of America-Kansas City.

Prosecutors accuse the Rysers of fraudulent billing and falsifying insurance claims.

Online court records don’t list a lawyer for the Rysers, and messages left at the clinic weren’t immediately returned Wednesday.
