New Medical Evidence at the Appeals Council

The Appeals Council will consider new medical evidence only under narrow conditions set by 20 CFR 404.970(a)(5). The evidence must be new, material, and relate to the period on or before the date of the ALJ hearing decision, and there must be a reasonable probability that it would change the outcome. On top of all that, 404.970(b) requires good cause for not having submitted the evidence earlier.

These rules surprise claimants who assume anything from a doctor can be added at any stage. Understanding each requirement before you file helps you present the evidence the Council can lawfully consider, and it protects your back pay if the Council concludes your records arrived too late or cover the wrong time period.

Why the Rules Are Strict

The hearing level is where evidence belongs. The regulations governing hearings, including the submission deadline described in 20 CFR 404.935 that requires informing SSA about evidence within 5 business days before a scheduled hearing, are designed so the Administrative Law Judge (ALJ) who actually hears testimony also sees the full record. The current version of 404.970, restated in a final rule published November 16, 2020, carries forward the framework SSA adopted to enforce that sequencing.

At the Council level, the question is whether the ALJ's decision was wrong on the record plus limited, properly justified additions, not whether a better record could have been built from scratch.

The Chronological Requirement

The phrase that does most of the work in 404.970(a)(5) is "relates to the period on or before the date of the hearing decision." Evidence qualifies only if it speaks to your condition during the window the ALJ was deciding, generally from your alleged onset date through the decision date.

A report typed after the decision can still qualify if it describes treatment, testing, or functioning that occurred before the decision date. An MRI report written three weeks after the decision but describing images taken months earlier is the sort of document that can relate to the right period. By contrast, records documenting a new diagnosis, a surgery, or a worsening that first occurred after the decision date usually do not relate to that period, because they cannot show what your capacity was when the ALJ evaluated it.

Evidence about later periods has a proper home: a new application. The date lines matter enormously for SSDI because past-due benefits are calculated from your established onset and filing dates, not from how long an appeal took.

New, Material, and Likely to Matter

The remaining elements of the test filter out clutter. New means the evidence is not merely duplicative of what is already in the record, such as another copy of records the ALJ already considered. Material means the evidence bears directly on a finding actually at issue, such as your residual functional capacity, whether your impairment meets a listing in 20 CFR Part 404, Subpart P, Appendix 1, or your credibility.

The reasonable probability standard is deliberately demanding. Under 404.970(a)(5), the Council must see a reasonable probability that the additional evidence would change the outcome of the decision. A routine progress note that echoes the existing record will not clear that bar, while a treating specialist's detailed functional assessment covering the relevant period might.

The Good Cause Requirement

Even chronologically proper evidence is considered only if you show good cause for not informing SSA about it or submitting it earlier, as described in 20 CFR 404.935. Under 404.970(b), good cause exists in three situations.

First, SSA's action misled you. Second, you had a physical, mental, educational, or linguistic limitation that prevented you from informing SSA or submitting the evidence earlier. Third, some other unusual, unexpected, or unavoidable circumstance beyond your control prevented earlier submission.

The regulation gives concrete examples of that third category: you were seriously ill and unable to contact SSA; there was a death or serious illness in your immediate family; important records were destroyed or damaged by fire or other accidental cause; or you actively and diligently sought evidence from a source and did not receive it, or received it less than 5 business days before the hearing. Explain your situation in writing and attach any support, such as a letter from a medical records office confirming a delayed release.

How and When to Submit

Under 20 CFR 404.968(a), you should submit the evidence you want considered together with your request for review, which means with Form HA-520. If records are still being gathered, the form's checkbox lets you request an extension of time to submit evidence or argument, and SSA's form page instructs claimants to request that extension in writing at the time of filing.

The same page carries a warning that decides many cases: if you submit neither evidence nor legal argument when you file, and no extension is granted, the Council will take its action based on the evidence currently in your file. Silence at filing time is treated as having nothing further to offer.

Exhibits and the Official Record

Not everything you send becomes an exhibit. Under 20 CFR 404.976(b), the Council evaluates all additional evidence it receives but marks as an exhibit, meaning makes part of the official record, only the evidence it determines meets the requirements of 404.970(a)(5) and (b).

There is a later safety valve for litigation. The same regulation provides that if a certified administrative record must be filed in federal court, it will include all additional evidence the Council received during administrative review, even evidence the Council received but did not exhibit. So a rejected submission can still travel with the case, although the Council itself will not rely on it.

If the Council Does Not Accept the Evidence

Under 20 CFR 404.970(c), when your evidence fails the date test or the good cause test, the Council sends a notice explaining why it did not accept it and advising you of the right to file a new application. The notice also explains a valuable protection: if you file that new application within 6 months after the date of the Council's notice, your request for review counts as a written statement of intent to claim benefits under 20 CFR 404.630, and SSA uses the date you requested Appeals Council review as the filing date of the new application.

That rule can preserve a meaningful amount of retroactivity, because under 20 CFR 404.621 a disability applicant can receive benefits for up to 12 months immediately before the month the application is filed. Acting within the 6-month window keeps the earlier date attached.

Practical Steps for a Stronger Submission

Organize what you send. A short cover letter that lists each document, states the dates it covers, explains how it relates to the period before the hearing decision, and sets out your good cause reasons gives the reviewing judge a path through the material. Keep a copy of everything and proof of mailing or fax transmission.

Keep the submission honest about dates. Resist any temptation to characterize post-decision events as earlier ones, because the Council checks chronology against the record, and accuracy is what makes the good cause statement credible.

Frequently Asked Questions

Can I submit medical records dated after my ALJ hearing decision? Only evidence that relates to the period on or before the date of the hearing decision can be considered under 20 CFR 404.970(a)(5). Records describing treatment you received before that date can qualify even if they were written later, while evidence about later-developing conditions generally belongs in a new application.

What counts as good cause for submitting evidence late to the Appeals Council? Under 20 CFR 404.970(b), good cause exists if SSA's action misled you, if a physical, mental, educational, or linguistic limitation prevented earlier submission, or if another unusual, unexpected, or unavoidable circumstance beyond your control did so, such as serious illness, a death in your immediate family, or records destroyed by fire.

What happens if the Appeals Council rejects my new evidence? Under 20 CFR 404.970(c), the Council mails a notice explaining why it did not accept the evidence and advising you of the right to file a new application. If you file that new application within 6 months of the notice, SSA uses the date you requested Appeals Council review as the new filing date.
