Iowa Code § 97A.13: Protection against fraud.

Any person who shall knowingly make any false statement, or shall falsify or permit to be falsified any record or records of the system in any attempt to defraud the system as a result of such act, shall be guilty of a fraudulent practice. Should any change or error in records result in any member or beneficiary receiving from the system more or less than the person would have been entitled to receive had the records been correct, the board of trustees shall correct such error, and, as far as practicable, shall adjust the payments in such a manner that the actuarial equivalent of the benefit to which such member or beneficiary was correctly entitled, shall be paid.
