The jurisdiction of the industrial commission and the authority of the administrator of workers' compensation over each case is continuing, and the commission may make such modification or change with respect to former findings or orders with respect thereto, as, in its opinion is justified. No modification or change nor any finding or award in respect of any claim shall be made with respect to disability, compensation, dependency, or benefits, after six years from the date of injury in the absence of the payment of medical benefits under this chapter, in which event the modification, change, finding, or award shall be made within six years after the payment of medical benefits, or in the absence of payment of compensation under section 4123.57, 4123.58, or division (A) or (B) of section 4123.56 of the Revised Code or wages in lieu of compensation in a manner so as to satisfy the requirements of section 4123.84 of the Revised Code, in which event the modification, change, finding, or award shall be made within ten years from the date of the last payment of compensation or from the date of death, nor unless written notice of claim for the specific part or parts of the body injured or disabled has been given as provided in section 4123.84 or 4123.85 of the Revised Code, and the commission shall not make any modification, change, finding, or award which shall award compensation for a back period in excess of two years prior to the date of filing application therefor. This section does not affect the right of a claimant to compensation accruing subsequent to the filing of any such application, provided the application is filed within the time limit provided in this section.

This section does not deprive the commission of its continuing jurisdiction to determine the questions raised by any application for modification of award which has been filed with the commission after June 1, 1932, and prior to the expiration of the applicable period but in respect to which no award has been granted or denied during the applicable period.

The commission may, by general rules, provide for the destruction of files of cases in which no further action may be taken.

The commission and administrator of workers' compensation each may, by general rules, provide for the retention and destruction of all other records in their possession or under their control pursuant to section 121.211 and sections 149.34 to 149.36 of the Revised Code. The bureau of workers' compensation may purchase or rent required equipment for the document retention media, as determined necessary to preserve the records. Photographs, microphotographs, microfilm, films, or other direct document retention media, when properly identified, have the same effect as the original record and may be offered in like manner and may be received as evidence in any court where the original record could have been introduced.
