OKLAHOMA CITY - An Oklahoma City dentist accused of submitting claims for dental services she didn't provide has been charged in federal court with health care fraud.

The Oklahoma Attorney General's office says 44-year-old Robin Lockwood faces one count of health care fraud.

The attorney general says the charges allege Lockwood falsified treatment notes submitted by Ocean Dental for Medicaid reimbursement between July 2007 and December 2010. She is accused of benefiting from the scheme because she received a percentage of the reimbursement for her services.

Among other things, Lockwood also is accused of billing for multi-surface fillings that she didn't complete.

The charges stem from an investigation by the state Attorney General's Medicaid Fraud Control Unit.

Her attorney, John Coyle, didn't immediately return a message left Saturday seeking comment.
