Todd Faustin, 43, of Coram pleaded guilty to making a false health care statement in connection to a claim made about an incident at Rikers Island, according to the New York State Department of Investigation.
He agreed to pay both restitution and forfeiture, each to the amount of $370,336.79.
The DOI looked into Faustin's claim after several New York City agencies reported excessive worker's compensation claims made by city correction officers.
Faustin said he was injured while on duty during an incident that required the use of force against Rikers Island prisoners. He received at least $370, 336.79 in benefits not owed to him, DOI said.
He resigned from his post effective March 17 and was suspended during the investigation.
His annual salary was approximately $109, 350. He started his employment with the City Department of Correction in 2011.
Expected to be sentenced on July 7.
