An amended alleged onset date is an alleged onset date (AOD) the claimant revises
after the field office (FO) sends the claim to the Disability Determination Services
(DDS). Based on the technical and medical requirements for the established onset date
(EOD), a claimant may want to amend his or her AOD after filing. If a claimant decides
to amend his or her AOD, he or she can do so by contacting us via letter, telephone,
visiting a field office, or by providing testimony at a hearing. The amended AOD may
be earlier or later than the original AOD.
We will allow the claimant to amend his or her AOD any time up to the date of the
DDS determination. If a claimant asks about amending his or her AOD, we will explain
the criteria and implications of our onset policy to the claimant. However, under
no circumstances will we persuade or require the claimant to amend his or her AOD.
If the claimant amends his or her AOD, the amended AOD is the starting point for medical
development.
EXAMPLE: Michael filed a disability insurance benefit (DIB) claim. He alleged disability due
to complications from an automobile accident. He alleged an onset date of 04/10/2010,
the date he last worked. DDS contacted the claimant and learned the claimant was involved
in the automobile accident on 07/15/2010. The claimant reported he had no limitations
prior to the automobile accident. The disability examiner spoke to the claimant about
the medical criteria necessary to establish an onset date. Michael reported he was
not aware of the medical criteria needed to establish an onset date when he initially
applied for DIB benefits and wanted to change his AOD to 07/15/2010, the date of the
automobile accident. The claimant’s amended AOD is 07/15/2010.
