The former owner of a speech therapy company was sentenced to two years in prison for submitting fraudulent claims to Medicaid totaling more than $582,000, according to the state Attorney General’s office.

Timothy Robinson must also pay back the money and will be on probation for eight years after being released from prison, Attorney General Sam Olens said. Robinson, who owned Robinson Rehabilitation Services based in Cobb County, pleaded guilty to one count of Medicaid fraud in April.

“My office takes seriously our responsibility to ensure that those who steal from Georgia Medicaid are held accountable,” Olens said in an emailed statement. “This case sends a strong message that the false billing of Medicaid will not be tolerated. Mr. Robinson has learned that lesson and is now paying for his actions with a prison sentence.”

Robinson employed four speech therapists that provided services around metro Atlanta, and was authorized to submit billing on their behalf to Georgia Medicaid.

During 2009 and 2010, all four speech therapists resigned from Robinson's company, but Robinson continued billing for services using the four providers' identification, according to investigators. In July 2013, Robinson was indicted in the case, The Atlanta Journal-Constitution previously reported.
