The regulations that require a notice for an initial determination contemplate a correct
notice will be sent. SSA considers that an initial determination has been made even
if we send an incorrect notice (e.g., an allowance instead of a denial).
When a determination or decision is made with respect to eligibility, amount or the
actual payment of benefits, the individual to whom that determination or decision
applies should be able to rely on its correctness. Once issued, the initial determination
is binding unless appealed or revised.
If the claimant files a reconsideration request after the time limit for filing an
appeal has expired, we would find good cause for extending the time limit due to misinformation
resulting from the defective notice.
