A former director of a Baton Rouge rehabilitation and detoxification treatment center admitted in federal court Thursday that she surreptitiously used patient information to obtain and distribute thousands of prescription medications.

Shanta R. Barnes, 49, also obtained Medicaid reimbursements for the drugs, U.S. Attorney Walt Green said.

Barnes pleaded guilty Thursday to health care fraud and aggravated identity theft. U.S. District Judge James Brady did not schedule a sentencing date.

Barnes served as program director for Louisiana Health and Rehabilitation Options, an in-patient center.

Green said Barnes obtained nearly 6,000 oxycodone pills in less than a year.

She was one of more than 280 people arrested by federal agents earlier this year in a multistate illegal prescription drug sweep dubbed Operation Pilluted.
