A former medical office administrator in Lincoln has pleaded guilty to a federal charge of wire fraud.

54-year-old Royann Schmidgall had faced 15 counts, but prosecutors have agreed to drop all but one in exchange for her plea on Thursday.

Prosecutor Alan Everett says there’s also an agreement that Schmidgall should face no more than 18 months in prison. The charge carries a maximum prison term of 20 years.

Prosecutors say Schmidgall handled payroll and other administrative duties at Nebraska Pulmonary Specialties for 15 years. Nebraska Pulmonary Specialties says in its pending lawsuit against Schmidgall that she embezzled nearly $634,000 over several years.
