(a) Except as otherwise provided by this subsection, if an examiner discovers an error in connection with a determination or discovers additional information not previously available, the examiner, within the period specified in Section 212.053(1), may reconsider and redetermine the determination. An examiner may issue a redetermination to correct a clerical or machine error at any time during a claimant's benefit year.
(b) An examiner's redetermination replaces the original determination and becomes final unless the claimant or the person for which the claimant last worked files an appeal from the redetermination not later than the 14th calendar day after the date on which a copy of the redetermination is mailed to the claimant's or person's last known address as shown by commission records.
