(i)#
an individual is a recipient of benefits based on disability or blindness under this subchapter,
(ii)#
the physical or mental impairment on the basis of which such benefits are payable is found to have ceased, not to have existed, or to no longer be disabling, and as a consequence such individual is determined not to be entitled to such benefits, and
(iii)#
a timely request for review or for a hearing is pending with respect to the determination that he is not so entitled,
such individual may elect (in such manner and form and within such time as the Commissioner of Social Security shall by regulations prescribe) to have the payment of such benefits continued for an additional period beginning with the first month beginning after October 9, 1984 , for which (under such determination) such benefits are no longer otherwise payable, and ending with the earlier of (I) the month preceding the month in which a decision is made after such a hearing, or (II) the month preceding the month in which no such request for review or a hearing is pending.
