If the decision is the initial denial, you must file a Request for Reconsideration with the Social Security Administration. If it is the second denial (after the review based on your Request for Reconsideration), then you must file a Request for Hearing. You have 60 days from the date of a Social Security determination to request a review of that decision. Failure to timely file the appropriate paperwork with the Social Security Administration will end the application for benefits.
