Kan. Stat. § 20-2612
Annuity payments to a judge who has retired under K.S.A. 20-2608 shall continue until the end of the month in which such judge shall die. The last annuity payment and any other payments to which such judge shall be entitled and which have not been paid at the time of his death shall be paid to his beneficiary. A judge who is receiving annuity payments under K.S.A. 20-2609 shall continue to receive such annuities as long as he is permanently disabled, and if such judge shall die while so disabled, payment of annuities shall be terminated in the same manner as hereinbefore provided for a judge who dies subsequent to his retirement. Any judge who is receiving annuities under K.S.A. 20-2609 may be required by the supreme court to submit to a re-examination at any time. Any such judge shall have the right to re-examination upon application to the court but not more often than once every six months.
A physician appointed by the court shall make such examinations and report his findings to the court which shall make a determination. In the event the court shall find that the permanent disability no longer exists the court shall so notify the board and thereupon said board shall discontinue annuity payments to such judge unless said judge has in the meantime qualified for retirement by reason of his age. If any judge refuses to submit to such re-examination the court shall so inform the board which shall immediately terminate all annuity payments to such judge. Costs incurred by the supreme court for the services of a physician as authorized by this act shall be paid by the board out of moneys appropriated to administer this act, and shall not be paid out of the fund.
