(a) (1) After an application for a hearing has been filed pursuant to Kan. Stat. Ann. § 44-534, and amendments thereto, the employee or the employer may make application for a preliminary hearing, in such form as the director may require, on the issues of the furnishing of medical treatment and the payment of temporary total or temporary partial disability compensation. At least seven days prior to filing an application for a preliminary hearing, the applicant shall give written notice to the adverse party of the intent to file such an application. Such notice of intent shall contain a specific statement of the benefit change being sought that is to be the subject of the requested preliminary hearing. If the parties do not agree to the change of benefits within the seven-day period, the party seeking a change in benefits may file an application for preliminary hearing which shall be accompanied by a copy of the notice of intent and the applicant’s certification that the notice of intent was served on the adverse party or that party’s attorney and that the request for a benefit change has either been denied or was not answered within seven days after service. Copies of medical reports or other evidence which the party intends to produce as exhibits supporting the change of benefits shall be included with the application. The director shall assign the application to an administrative law judge who shall set the matter for a preliminary hearing and shall give at least seven days’ written notice by mail to the parties of the date set for such hearing.

(2) Such preliminary hearing shall be summary in nature and shall be held by an administrative law judge in any county designated by the administrative law judge, and the administrative law judge shall exercise such powers as are provided for the conduct of full hearings on claims under the workers compensation act. Upon a preliminary finding that the injury to the employee is compensable and in accordance with the facts presented at such preliminary hearing, the administrative law judge may make a preliminary award of medical compensation and temporary total disability compensation to be in effect pending the conclusion of a full hearing on the claim, except that if the employee’s entitlement to medical compensation or temporary total disability compensation is disputed or there is a dispute as to the compensability of the claim, no preliminary award of benefits shall be entered without giving the employer the opportunity to present evidence, including testimony, on the disputed issues. A finding with regard to a disputed issue of whether the employee suffered an accident, repetitive trauma or resulting injury, whether the injury arose out of and in the course of the employee’s employment, whether notice is given, or whether certain defenses apply, shall be considered jurisdictional, and subject to review by the board. Such review by the board shall not be subject to judicial review. If an appeal from a preliminary order is perfected under this section, such appeal shall not stay the payment of medical compensation and temporary total disability compensation from the date of the preliminary award. If temporary total compensation is awarded, such compensation may be ordered paid from the date of filing the application, except that if the administrative law judge finds from the evidence presented that there were one or more periods of temporary total disability prior to such filing date, temporary total compensation may be ordered paid for all periods of temporary total disability prior to such date of filing. The decision in such preliminary hearing shall be rendered within five days of the conclusion of such hearing. Except as provided in this section, no such preliminary findings or preliminary awards shall be appealable by any party to the proceedings, and the same shall not be binding in a full hearing on the claim, but shall be subject to a full presentation of the facts.

(b) If compensation in the form of medical benefits or temporary total disability benefits has been paid by the employer or the employer’s insurance carrier either voluntarily or pursuant to an award entered under this section and, upon a full hearing on the claim, the amount of compensation to which the employee is entitled is found to be less than the amount of compensation paid or is totally disallowed, the employer and the employer’s insurance carrier shall be reimbursed from the workers compensation fund established in Kan. Stat. Ann. § 44-566a, and amendments thereto, for all amounts of compensation so paid which are in excess of the amount of compensation the employee is entitled to less any amount deducted from additional disability benefits due the employee pursuant to subsection (c) of Kan. Stat. Ann. § 44-525, and amendments thereto, as determined in the full hearing on the claim. The director shall determine the amount of compensation paid by the employer or insurance carrier which is to be reimbursed under this subsection, and the director shall certify to the commissioner of insurance the amount so determined. Upon receipt of such certification, the commissioner of insurance shall cause payment to be made to the employer or the employer’s insurance carrier in accordance therewith. No reimbursement shall be certified unless the request is made by the employer or employer’s insurance carrier within one year of the final award.
