A 61-year-old Newtown psychologist has been charged by state investigators for allegedly bilking the Medicaid program of $79,418 for services she never performed.

Inspectors from the Medicaid Fraud Control Unit in the Office of the Chief State’s Attorney said Monday they were “tipped off by a former employee” about the alleged abuses by Jeannie Pasacreta, who operates Integrated Mental Health Services on Abbey Lane.
