A blind DIB, CDB, or DWB claimant, age 55 or older, may be found disabled if he or
she is unable to engage in SGA requiring skills or abilities comparable to those of
any gainful activity in which he or she was previously engaged with some regularity
and over a substantial period of time prior to onset of blindness or the attainment
of age 55, whichever is later. If such an individual does engage in noncomparable
SGA, he or she may be entitled to disability benefit status (SSA-831-U3, item 18B),
but cash benefit payments will be suspended as long as the individual is actually
engaging in any SGA.
