OKLAHOMA CITY (AP) - A former Oklahoma oral surgeon whose filthy clinics led to thousands of patients being tested for HIV and hepatitis has pleaded guilty to depositing at least $15,000 of fraudulent Medicaid billings into a personal account.

Wayne Scott Harrington, who had previously pleaded not guilty to the same money-laundering charge, could face up to 10 years in prison and a fine of up to $250,000 at a sentencing hearing scheduled for July 14. Harrington also agreed to pay nearly $30,000 in restitution.

U.S. attorneys say Harrington, 67, billed Medicaid in 2012 for anesthesia he did not personally administer.

Harrington's attorney Dan Webber says his client has accepted responsibility for his conduct regarding the money-laundering charge. Webber says he looks forward to telling the court more about Harrington before the sentencing hearing.
