CASPER, Wyo. (AP) — A federal grand jury has charged three Wyoming men after prosecutors say they were involved with a yearslong Medicaid fraud scheme.

The Casper Star-Tribune reported Wednesday that prosecutors allege the men billed the government $8.5 million worth of therapy for gym exercises and video games.

Prosecutors say Matthew Barrus and Gregory Bennett billed and collected millions from Medicaid for what they said was therapy, but that Medicaid doesn’t deem reimbursable treatment.

Prosecutors say the third man Devin Dutson helped bill for alcohol and drug treatment when his juvenile patients were actually weightlifting and exercising.

The men face multiple charges including health care fraud and racketeering.

Bennett’s attorney Ian Sandefer declined to comment for this story. Lawyers for Barrus and Dutson could not be reached by phone Wednesday.
