(A) Once each year during the first five years following the retirement of a member on a disability retirement allowance and once in every three-year period thereafter the board may, and upon his application, require any disability beneficiary who has not yet attained the age of sixty-five years to undergo a medical examination to be made at the place of residence of the beneficiary or other place mutually agreed upon by a physician designated by the board. If any disability beneficiary who has not yet attained the age of sixty-five years refuses to submit to at least one medical examination in any such year by a physician designated by the board the member’s disability retirement allowance may be discontinued until the member’s withdrawal of refusal and if the member’s refusal continues for one year, all the member’s rights in and to the member’s disability retirement allowance may be revoked by the board.

(B) A member who is retired on a disability retirement allowance based upon an application received by the system after December 31, 2013, and who has not yet attained the age of sixty-five years annually shall provide proof to the system that the member remains qualified for the receipt of Social Security disability benefits within thirty days of the anniversary of his retirement date. A member’s disability retirement allowance ceases upon a determination by the Social Security Administration that the member is no longer entitled to Social Security disability benefits for any reason. If any disability beneficiary who has not yet attained the age of sixty-five years refuses to provide proof of disability required by the board, the member’s disability retirement allowance must be discontinued until the member provides such proof. If a member’s refusal to provide proof that the member remains qualified for Social Security disability benefits continues for one year, all of the member’s rights in and to the member’s disability retirement allowance pursuant to § 9-1-1540 may be revoked by the board.
