LINCOLN, Neb. (AP) — Authorities say a woman who provided house care and other aid for an ailing man overbilled Medicaid for services she never provided.

55-year-old Debra Dukes is charged with two counts of fraud to obtain assistance of more than $500. Court records don’t list the name of an attorney who could comment for her.

An arrest affidavit says investigators found she was paid more than $8,700 for 1,400 hours of aid that actually overlapped times the man was in a medical treatment facility. The affidavit says that under a service provider agreement she signed, she couldn’t bill Medicaid while her client was in such a facility.
