You have the right to appeal any decision Social Security makes as to your entitlement to Social Security benefits or Supplemental Security Income (SSI) payments.
The first step in the appeals process is called a reconsideration determination. You will receive a new decision by someone who had no part in the first decision. The Social Security Administration (SSA) will send you a letter explaining how they made the decision. It is very difficult to get SSA to change their minds in a reconsideration request unless there is substantial medical information that was not received or considered during the initial determination.
