AUGUSTA — The Maine attorney general’s office is taking another shot at regaining federal certification for the state-run Riverview Psychiatric Center in Augusta.

At stake is millions of dollars in federal funding for the 92-bed psychiatric hospital.

The U.S. Centers for Medicare and Medicaid Services pulled the hospital’s certification last year after determining the facility was not compliant with federal rules, including in the ways it dealt with patients.

Maine last month lost an appeal to the U.S. Department of Health and Human Services.

A spokesman for Attorney General Janet Mills tells the Portland Press Herald that Maine will now go to federal court.

Riverview houses mental health patients, some of whom have been convicted of crimes and some of whom await trial.
