A party must file a request for administrative review within 30 days after the date
of the notice of SSA's initial fee authorization.
If the party files a request for administrative review more than 30 days after the
date of the notice, the party must explain in writing why the review was not filed
In those cases, SSA will conduct an administrative review only if it determines that
there was good cause for not filing the request on time. The reviewing office will
determine whether there was good cause for late filing (see GN 03950.020).
