How to appeal. If all or part of your written request was denied, you may request that the Commissioner of Social Security, 6401 Security Boulevard, Baltimore, MD 21235 review that determination. Your request for review:

Must be in writing;

Must be mailed within 30 days after you received notification that all or part of your request was denied or, if later, 30 days after you received materials in partial compliance with your request; and

May include additional information or evidence to support your request.

How the review is made. After reviewing the prior decision and after considering anything else you have submitted, the Commissioner or his or her designee will affirm or revise all or part of the prior decision. The Commissioner (or a designee) will affirm a denial only after consulting with the appropriate SSA official(s), including legal counsel. The decision must be made within 20 working days after your appeal is received. The Commissioner or a designee may extend this time limit up to 10 additional working days if one of the situations in § 402.140(a) exists, provided that, if a prior extension was used to process this request, the sum of the extensions may not exceed 10 working days. You will be notified in writing of any extension, the reason for the extension, and the date by which your appeal will be decided.

How you are notified of the Commissioner's decision. The Commissioner or a designee will send you a written notice of the decision explaining the basis of the decision (for example, the reasons why an exemption applies) which will include the name and title or position of the person who made the decision. The notice will tell you that if any part of your request remains unsatisfied, you have the right to seek court review.
