If there is a dispute who decides what is owed?

Disputes are decided by the Iowa workers' compensation commissioner, an administrative agency of the state of Iowa which is part of Iowa Workforce Development. Administrative law judges called deputy worker's compensation commissioner preside at the initial hearing and issue proposed agency decisions which become final agency decisions unless appealed to the workers' compensation commissioner. An appeal decision of the workers' compensation commissioner is a final agency decision subject to appeal by filing a petition for judicial review with the Iowa district court. Judicial review decisions of the Iowa District Court are subject to appellate review by the Iowa Supreme Court and Court of Appeals.
