 (from Ch. 108 1/2, par. 15-153.2)Sec. 15-153.2. Disability retirement annuity. A participant whose  disability benefits are discontinued under the provisions of clause (6) of  Section 15-152 and who is not a participant in the optional retirement plan  established under Section 15-158.2 is entitled to a disability  retirement annuity of 35% of the basic compensation which was payable to the  participant at the time that disability began, provided that the board determines that the participant has a medically determinable physical or  mental impairment that prevents him or her from  engaging in any substantial gainful activity, and which can be expected to  result in death or which has lasted or can be expected to last for a continuous  period of not less than 12 months.The board's determination of whether a participant is disabled shall be  based upon:(i) a written certificate from one or more licensed     and practicing physicians appointed by or acceptable to the board, stating that the participant is unable to engage in any substantial gainful activity; and(ii) any other medical examinations, hospital     records, laboratory results, or other information necessary for determining the employment capacity and condition of the participant.The terms "medically determinable physical or mental impairment" and  "substantial gainful activity" shall have the meanings ascribed to them in the  federal Social Security Act, as now or hereafter amended, and the  regulations issued thereunder.The disability retirement annuity payment period shall begin immediately  following the expiration of the disability benefit payments under clause  (6) of Section 15-152 and shall be discontinued for a recipient of a disability retirement annuity when (1) the physical or  mental impairment no longer prevents the recipient from engaging in any  substantial gainful activity, (2) the recipient dies, (3) the recipient   elects to receive a retirement annuity under Sections 15-135 and 15-136, (4) the recipient refuses to submit to a reasonable physical examination by a physician approved by the board, or (5) the recipient fails to provide an earnings verification necessary to determine continuance of benefits.  If a person's disability retirement annuity is discontinued under clause  (1), all rights and credits accrued in the system on the date that the  disability retirement annuity began shall be restored, and the disability  retirement annuity paid shall be considered as disability payments under  clause (6) of Section 15-152.The board shall adopt rules governing the filing, investigation, control, and supervision of disability retirement annuity claims. Costs incurred by a claimant in connection with completing a claim for a disability retirement annuity shall be paid: (A) by the claimant in the case of the one required medical examination, medical certificate, and any other requirements generally imposed by the board on all disability retirement annuity claimants; and (B) by the System in the case of any additional medical examination or other additional requirement imposed on a particular claimant that is not imposed generally on all disability retirement annuity claimants.(Source: P.A. 100-556, eff. 12-8-17.)
