Social Security Disability SSI and the Onset Date
The AOD or alleged onset date is the date a disability applicant states that they became unable to perform substantial work activity or SGA due to their physical or mental impairment.
EOD or established onset date is the date the Social Security has determined to be when an individualís impairment actually met the definition of disability for Social Security.
Most often the AOD and EOD are determined to be the same date, which allows for a fully favorable decision for a claimant. However if an applicant has no medical evidence to support their AOD or they performed SGA after they alleged they became unable to perform SGA, they may have an EOD that is later than their AOD.
If there is not objective medical evidence to support the AOD, the disability examiner will determine when they have enough evidence to support a finding of disability at a later date and if they are able to do so the later date will become the EOD.
If the disability applicant worked past their AOD, their established date of onset cannot be any earlier than the date they stopped performing SGA no matter how serious their disabling condition might be.
