If OWCP issues a formal loss of wage-earning capacity determination, including a finding of no loss of wage-earning capacity, that determination and rate of compensation, if applicable, remains in place until that determination is modified by OWCP. Modification of such a determination is only warranted where the party seeking the modification establishes either that there is a material change in the nature and extent of the injury-related condition, the employee has been retrained or otherwise vocationally rehabilitated, or the original determination was erroneous. However, OWCP is not precluded from adjudicating a limited period of disability following the issuance of a loss of wage-earning capacity decision, such as where an employee has a demonstrated need for surgery.
