Getting a Social Security disability denial letter can feel like the process is over. In many cases, it is not. For SSDI and SSI applicants, reconsideration is usually the first appeal step after an initial denial, and the filing window is tighter than many people realize. The Social Security Administration says a reconsideration request generally has to be filed within 60 days after you receive the notice, and SSA usually assumes you received the notice 5 days after the date on the letter unless you can show otherwise (SSA appeals overview; SSA Handbook § 2001).
That deadline matters because if the appeal is not filed on time, the denial can become final unless SSA finds “good cause” to extend the time (SSA Handbook § 2001; 20 C.F.R. § 404.911). In practical terms, many people find themselves juggling medical treatment, paperwork, and stress while the clock is already running.
In this post, you’ll learn how to calculate the deadline, how to file reconsideration, what forms often come up, what evidence may help, and what to do if time is getting short. If you want a broader overview of where reconsideration fits in the appeal process, this guide on the first disability appeal step can help set the stage.

The phrase “60-day deadline” is a little misleading. SSA’s rule is tied to the date you receive the notice, and the agency generally presumes receipt 5 days after the date on the notice unless you prove later delivery (SSA appeals overview; SSA Handbook § 2192).
So if your denial notice is dated April 1, 2026, SSA would ordinarily presume you received it on April 6, 2026, and the 60-day appeal period would typically run from there. If the final day lands on a Saturday, Sunday, legal holiday, or federal non-work day, the deadline is extended to the next workday (SSA Handbook § 2001).
That means the safest approach is often to treat the appeal as urgent the moment the denial letter arrives. Delays related to getting records, finding representation, or deciding what to say on the form can eat up time quickly.
Reconsideration is SSA’s review of an initial determination you disagree with. In a disability claim, it usually means a new reviewer takes another look at the file and any additional evidence you submit (SSA Form SSA-561 page; SSA appeals overview).
For medical disability denials, reconsideration is generally a record review with updated evidence, not a courtroom-style hearing. SSA notes that if you applied for Social Security disability or SSI disability benefits and were denied for medical reasons, you may request that appeal online or by using Form SSA-561, and medical reconsideration requests typically also involve Form SSA-827 so SSA can obtain records (SSA Form SSA-561 page).
This step may feel repetitive, but it is still an active appeal stage. According to SSA’s Annual Statistical Report on the Social Security Disability Insurance Program, 2024, allowance rates at the reconsideration level remain much lower than at the hearing level, which is one reason many claimants try to strengthen the record as early as possible (SSA DI Statistical Report, Table 62). SSA’s SSI statistical report also notes that reconsideration outcomes were affected for years by the former prototype process, which had eliminated reconsideration in certain states until it was fully reinstated by March 31, 2020 (SSA SSI Statistical Report, 2024).
Before filing anything, it helps to read the denial notice line by line. The notice usually tells you:
