B. In claims involving an employee who has a preexisting industrially-related permanent physical impairment of the type specified in section 23-1044, subsection B and who thereafter suffers an additional permanent physical impairment of the type specified in such subsection, the claim involving the subsequent impairment is eligible for reimbursement, as provided by subsection D of this section, according to the following:

1. 1. The employer in whose employ the subsequent impairment occurred or its insurance carrier is solely responsible for all temporary disability compensation to which the employee is entitled and for an amount equal to the permanent disability compensation provided by section 23-1044, subsection B for the subsequent impairment. If the employee is determined to have sustained no loss of earning capacity after the medically stationary date, the employer or carrier shall pay him as a vocational rehabilitation bonus the amount calculated under this paragraph as a lump sum, which shall be a credit against any permanent compensation benefits awarded in any subsequent proceeding. The amount of the vocational rehabilitation bonus for which the employer or carrier is responsible under this paragraph shall be calculated solely on physical, medically rated permanent impairment and not on occupational or other factors.
2. 2. If the commission determines that the employee is entitled to compensation for loss of earning capacity under section 23-1044, subsection C or permanent total disability under section 23-1045, subsection B, the total amount of permanent benefits for which the employer or carrier is solely responsible under paragraph 1 of this subsection shall be expended first, with monthly payments made according to the loss of earning capacity or permanent total disability award. The employer or carrier and the special fund are equally responsible for the remaining amount of compensation for loss of earning capacity under section 23-1044, subsection C or permanent total disability under section 23-1045, subsection B. This paragraph shall not be construed as requiring payment of any benefits under section 23-1044, subsection B in any case in which an employee is entitled to benefits for loss of earning capacity under section 23-1044, subsection C or permanent total disability benefits under section 23-1045, subsection B.

C. In claims involving an employee who has a preexisting physical impairment that is not industrially-related and, whether congenital or due to injury or disease, is of such seriousness as to constitute a hindrance or obstacle to employment or to obtaining reemployment if the employee becomes unemployed, and the impairment equals or exceeds a ten percent permanent impairment evaluated in accordance with the American medical association guides to the evaluation of permanent impairment, and the employee thereafter suffers an additional permanent impairment not of the type specified in section 23-1044, subsection B, the claim involving the subsequent impairment is eligible for reimbursement, as provided by subsection D of this section, under the following conditions:

1. 1. The employer in whose employ the subsequent impairment occurred or its carrier is solely responsible for all temporary disability compensation to which the employee is entitled.
2. 2. The employer had knowledge of the permanent impairment at the time the employee was hired, or that the employee continued in employment after the employer acquired such knowledge.

3. 3. The employee's preexisting impairment is due to one or more of the following:

   1. (a) Epilepsy.
   2. (b) Diabetes.
   3. (c) Cardiac disease.
   4. (d) Arthritis.
