The good cause for reopening rules
generally do not apply if the circumstances in Social Security Ruling (SSR) 91-5p: Mental Incapacity and Good Cause for Missing
the Deadline to Request Review exist. Under SSR 91-5p,
if a claimant presents evidence that mental incapacity prevented
him or her from timely requesting review of an adverse determination,
decision, dismissal, or review by a Federal district court, and
the claimant had no one legally responsible for prosecuting the
claim at the time of the prior administrative action (e.g., a parent
of a claimant who is a minor, legal guardian, attorney, or other
legal representative), the Social Security Administration (SSA) will
determine whether or not good cause exists for extending the time
to request review. If the claimant satisfies the substantive criteria,
the time limits in the reopening regulations do not apply. In that
case, regardless of how much time has passed since the prior administrative
action, the claimant can establish good cause for extending the
deadline to request review of that action.
