HOUSTON (AP) Federal authorities allege the owners of a mental health care company and some group care homes in Houston bilked Medicare out of $97 million for services that were not medically necessary or in some cases amounted to patients watching movies, coloring and playing games.

The charges are part of superseding indictment unsealed Thursday that charges eight people with a variety of counts, including conspiracy to commit health fraud.

Three of the defendants were originally indicted in December. All those indicted are to make appearances in the next few days in Houston federal court.

The indictment alleges the owners of the mental health care company, Spectrum Care P.A., as well as those running some group care homes falsely certified that patients qualified for medical services and billed Medicare for their treatment.
