A Marshalltown woman has been sentenced to six months in federal prison for diverting controlled substances and making false entries in medical records. Amanda Nicole Manatt, 37, was employed as a registered nurse at Unity Point Marshalltown Hospital, where she diverted drugs such as fentanyl, hydromorphone, and morphine by obtaining them under patients’ names and documenting them as administered before taking them for her own use.
Manatt’s employment at Unity Point ended in December 2023. She then worked at Mary Greely Medical Center starting January 2024, where she continued the same conduct with hydromorphone until her employment ended in April 2024.
Court documents indicate that some patients experienced pain because they did not receive the prescribed medications, while others received less than needed. The false documentation also led to health care benefit programs being billed for drugs not actually given to patients.
Following her prison term, Manatt will serve three years of supervised release. She was ordered to pay $5,258.20 in restitution, a $5,500 fine, and a $300 special assessment. There is no parole in the federal system.
“United States Attorney Richard D. Westphal of the Southern District of Iowa made the announcement. The Department of Inspections, Appeals, and Licensing (DIAL) Medicaid Fraud Control Unit (MFCU), the Tama County Sheriff’s Office, and the Iowa Insurance Fraud Bureau investigated this case.”
