20 CFR 416.1468 - How to request Appeals Council review.
(a)Time and place to request Appeals Council review. You may request Appeals Council review by filing a written request. Any documents or other evidence you wish to have considered by the Appeals Council should be submitted with your request for review. You should submit any evidence you wish to have considered by the Appeals Council with your request for review, and the Appeals Council will consider the evidence in accordance with § 416.1470.
(b)Extension of time to request review. You or any party to a hearing decision may ask that the time for filing a request for the review be extended. The request for an extension of time must be in writing. It must be filed with the Appeals Council, and it must give the reasons why the request for review was not filed within the stated time period. If you show that you had good cause for missing the deadline, the time period will be extended. To determine whether good cause exists, we use the standards explained in § 416.1411.
