(A) Within seven days after receipt of any claim under this chapter, the bureau of workers' compensation shall notify the claimant and the employer of the claimant of the receipt of the claim and of the facts alleged therein. If the bureau receives from a person other than the claimant written or telecommunicated information indicating that an injury or occupational disease has occurred or been contracted with may be compensable under this chapter, the bureau shall notify the employee and the employer of the information. If the information is provided by any method of telecommunication, the person providing the information shall provide written verification of the information to the bureau according to division (E) of section 4123.84 of the Revised Code. The receipt of the information in writing, or if by a method of telecommunications, the written verification, and the notice by the bureau shall be considered an application for compensation under section 4123.84 or 4123.85 of the Revised Code provided that the conditions of division (E) of section 4123.84 of the Revised Code apply to information provided by a method of telecommunication. Upon receipt of a claim, the bureau shall advise the claimant of the claim number assigned and the claimant's right to representation in the processing of a claim or to elect no representation. If the bureau determines that a claim is determined to be a compensable lost-time claim, the bureau shall notify the claimant and the employer of the availability of rehabilitation services. No bureau or industrial commission employee shall directly or indirectly convey any information in derogation of this right. This section shall in no way abrogate the bureau's responsibility to aid and assist a claimant in the filing of a claim and to advise the claimant of the claimant's rights under the law. The administrator of workers' compensation shall assign all claims and investigations to the bureau service office from which investigation and determination may be made most expeditiously. The bureau shall investigate the facts concerning an injury or occupational disease and ascertain such facts in whatever manner is most appropriate and may obtain statements of the employee, employer, attending physician, and witnesses in whatever manner is most appropriate.

(B)(1) Except as provided in division (B)(2) of this section, in claims other than those in which the employer is a self-insuring employer, if the administrator determines under division (A) of this section that a claimant is or is not entitled to an award of compensation or benefits, the administrator shall issue an order no later than twenty-eight days after the sending of the notice under division (A) of this section, granting or denying the payment of the compensation or benefits, or both as is appropriate to the claimant. Notwithstanding the time limitation specified in this division for the issuance of an order, if a medical examination of the claimant is required by statute, the administrator promptly shall schedule the claimant for that examination and shall issue an order no later than twenty-eight days after receipt of the report of the examination. The administrator shall notify the claimant and the employer of the claimant and their respective representatives in writing of the nature of the order and the amounts of compensation and benefit payments involved. The employer or claimant may appeal the order pursuant to division (C) of this section within fourteen days after the date of the receipt of the order. The employer and claimant may waive, in writing, their rights to an appeal under this division.

(2) Notwithstanding the time limitation specified in division (B)(1) of this section for the issuance of an order, if the employer certifies a claim for payment of compensation or benefits, or both, to a claimant, and the administrator has completed the investigation of the claim, the payment of benefits or compensation, or both, as is appropriate, shall commence upon the later of the date of the certification or completion of the investigation and issuance of the order by the administrator, provided that the administrator shall issue the order no later than the time limitation specified in division (B)(1) of this section.

(3) If an appeal is made under division (B)(1) or (2) of this section, the administrator shall forward the claim file to the appropriate district hearing officer within seven days of the appeal. In contested claims other than state fund claims, the administrator shall forward the claim within seven days of the administrator's receipt of the claim to the commission, which shall refer the claim to an appropriate district hearing officer for a hearing in accordance with division (C) of this section.

(C) If an employer or claimant timely appeals the order of the administrator issued under division (B) of this section or in the case of other contested claims other than state fund claims, the commission shall refer the claim to an appropriate district hearing officer according to rules the commission adopts under section 4121.36 of the Revised Code. The district hearing officer shall notify the parties and their respective representatives of the time and place of the hearing. The district hearing officer shall hold a hearing on a disputed issue or claim within forty-five days after the filing of the appeal under this division and issue a decision within seven days after holding the hearing. The district hearing officer shall notify the parties and their respective representatives in writing of the order. Any party may appeal an order issued under this division pursuant to division (D) of this section within fourteen days after receipt of the order under this division.

The commission shall hold the hearing within forty-five days after the filing of the notice of appeal and, within seven days after the conclusion of the hearing, the commission shall issue its order affirming, modifying, or reversing the order issued under division (D) of this section. The commission shall notify the parties and their respective representatives in writing of the order. If the commission or the designated staff hearing officer determines not to hear the appeal, within fourteen days after the filing of the notice of appeal, the commission or the designated staff hearing officer shall issue an order to that effect and notify the parties and their respective representatives in writing of that order. Except as otherwise provided in this chapter and Chapters 4121., 4127., and 4131. of the Revised Code, any party may appeal an order issued under this division to the court pursuant to section 4123.512 of the Revised Code within sixty days after receipt of the order, subject to the limitations contained in that section.

(J) Upon the final administrative or judicial determination under this section or section 4123.512 of the Revised Code of an appeal of an order to pay compensation, if a claimant is found to have received compensation pursuant to a prior order which is reversed upon subsequent appeal, the claimant's employer, if a self-insuring employer, or the bureau, shall withhold from any amount to which the claimant becomes entitled pursuant to any claim, past, present, or future, under Chapter 4121., 4123., 4127., or 4131. of the Revised Code, the amount of previously paid compensation to the claimant which, due to reversal upon appeal, the claimant is not entitled, pursuant to the following criteria:

(1) No withholding for the first twelve weeks of temporary total disability compensation pursuant to section 4123.56 of the Revised Code shall be made;

(K) If a staff hearing officer or the commission fails to issue a decision or the commission fails to refuse to hear an appeal within the time periods required by this section, payments to a claimant shall cease until the staff hearing officer or commission issues a decision or hears the appeal, unless the failure was due to the fault or neglect of the employer or the employer agrees that the payments should continue for a longer period of time.

(L) Except as otherwise provided in this section or section 4123.522 of the Revised Code, no appeal is timely filed under this section unless the appeal is filed with the time limits set forth in this section.
