Disability will be determined to have ceased in the month in which:
The impairment, as established by medical or other evidence, is not so severe as to
prevent the beneficiary from engaging in substantial gainful activity; or
The impairment no longer constitutes statutory blindness; or
The beneficiary demonstrates the ability to engage in Substantial Gainful Activity
NOTE: DIB entitlement will continue (excluding any other basis for cessation) for statutorily
blind claimants who meet Fully Insured status only (i.e., do not meet 20/40 or Special Insured status) and are subsequently determined
no longer stat blind but still disabled (i.e., have a non-blind impairment).
