More than 50% of Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) claimants will receive a Social Security Disability denial letter for their initial application. Denial letters are generally sent 30 to 90 days after the disability application is received by the Social Security Administration. In many parts of the country it may take even longer to process a SSDI or SSI application. The Social Security Disability denial letter will state the reasons the claimant's Social Security Disability Insurance or Supplemental Security Income benefits were denied, and it will list the medical documentation which the Social Security Administration used to make their disability decision. The Social Security Disability Denial letter will also outline how the claimant can appeal the disability decision. Claimants have 60 days from the date of the Social Security Disability denial letter to appeal the denial decision. The first step in the appeal process (for most parts of the country) is to file a reconsideration. Some disability claimants may be able to appeal directly for a Social Security Disability hearing and skip the reconsideration appeal level. If the claimant does not file a reconsideration within the specified time period, the Social Security Administration will take no further action for the disability claim.
