(a) Upon retirement for disability in accordance with N.C. Gen. Stat. § 135-59, a member shall receive a disability retirement allowance computed and payable as provided for service retirement in subsection (a6) of N.C. Gen. Stat. § 135-58, except that the member‘s creditable service shall be taken as the creditable service the member would have had if the member had continued in service to the earliest date the member could have retired on an unreduced service retirement allowance as a member in the same division of the General Court of Justice in which the member was serving on the member’s disability retirement date.

(b) Once each year during the first five years following retirement of a member on a disability retirement allowance, and once in every three-year period thereafter, the Board of Trustees may, and upon his application shall, require any disability beneficiary who has not yet attained his sixtieth birthday to undergo a medical examination, such examination to be made at the place of residence of the beneficiary or other place mutually agreed upon, by a physician or physicians designated by the Board of Trustees. Should any disability beneficiary who has not yet attained his sixtieth birthday refuse to submit to at least one medical examination in any such year by a physician or physicians designated by the Board of Trustees, his allowance may be discontinued until his withdrawal of such refusal, and should his refusal continue for one year, it shall be assumed that he is no longer disabled.

(c) Should the medical board certify to the Board of Trustees that a disability beneficiary prior to his sixty-fifth birthday has recovered to the extent that he would not satisfy the requirements for disability retirement if he were an active member of the Retirement System, or if his disability shall be assumed to have terminated in accordance with subsection (b) above, his disability retirement allowance shall thereupon cease, he shall be restored as a member of the Retirement System, and the period during which he was in receipt of a disability retirement allowance shall not be included in his creditable service.

(d) The Board of Trustees shall determine whether a disability beneficiary is engaged in or is able to engage in a gainful occupation paying more than the difference, as hereinafter indexed, between his disability retirement allowance and the gross compensation earned as an employee during the 12 consecutive months in the final 48 months of service prior to retirement producing the highest gross compensation excluding any compensation received on account of termination. If the disability beneficiary is earning or is able to earn more than the difference, the portion of his disability retirement allowance not provided by his contributions shall be reduced to an amount which, together with the portion of the disability retirement allowance provided by his contributions and the amount earnable by him shall equal the amount of his gross compensation prior to retirement. This difference shall be increased on January 1 of each year by the percentage change between the December Consumer Price Index in the year prior to retirement and the December Consumer Price Index in the year most recently ended, calculated to the nearest tenth of one percent (? of 1%), provided that this percentage change is positive. Should the earning capacity of the disability beneficiary later change, the portion of his disability retirement allowance not provided by his contributions may be further modified. In lieu of the reductions on account of a disability beneficiary earning more than the aforesaid difference, he may elect to convert his disability retirement allowance to a service retirement allowance calculated on the basis of his final compensation and creditable service at the time of disability retirement and his age at the time of conversion to service retirement. This election is irrevocable. (1973, c. 640, s. 1; 1981, c. 975, s. 4; c. 980, s. 5; 1983 (Reg. Sess., 1984), c. 1031, s. 19; 1999-237, s. 28.24(g); 2014-97, s. 4(h); 2022-16, s. 3.1.)
