20 CFR 404.957 in 2026: When ALJs Dismiss SSDI Hearing Requests, the Good Cause Standard for Failure to Appear, and How to Vacate a Dismissal That Killed Your Case

Published May 29, 2026 by Anthony Albert, Benefits Research Director at Disability Exchange. Reading time: 15 minutes.

A 404.957 dismissal is one of the cruelest outcomes in SSDI practice. It ends your case at the ALJ level without a decision on the merits. You don't get a finding on RFC. You don't get a vocational analysis. You don't get a step 5 determination. You get a dismissal order and a window to fix it, and if you miss that window you're starting over from scratch with a new application. The rule that governs this is 20 CFR 404.957, with the parallel Title XVI rule at 20 CFR 416.1457.

This piece breaks down the dismissal rule in detail: every subsection, every dismissal ground, the good cause standard for failure to appear, the 60-day vacate window under 20 CFR 404.960, the Appeals Council backstop under 404.967, the federal court limitation under Califano v. Sanders, and the procedural rules in HALLEX I-2-4-25 and I-2-4-40 that hearing offices actually use. If you got a dismissal notice and you're trying to figure out what your next move is, this is the field guide.

The Structure of 20 CFR 404.957

The rule has three top-level subsections, each with its own subparts.

Each of these has its own analysis. The defenses and procedural fixes differ depending on which subsection the ALJ cited.

Withdrawal Under 404.957(a)

This one is voluntary. You decided you wanted to pull your hearing request. Maybe you got new evidence and want to refile. Maybe you're settling at the initial level. Whatever the reason, you signed a withdrawal request and the ALJ dismissed the hearing.

The catch with withdrawal under 404.957(a) is that you waive your right to a hearing on this claim. You can still file a new application, but the new application is treated as a new claim with a new filing date, which can affect your protective filing date and the period covered by retroactive benefits. Before you withdraw, think hard about whether to keep the hearing on the calendar and ask for a postponement instead.

Failure to Appear Under 404.957(b)

This is the most common 404.957 dismissal. The ALJ scheduled a hearing, you didn't show, and the ALJ dismissed the hearing request.

The rule splits into two paths. Under (b)(1)(i), the ALJ can dismiss if you got proper prior notice that failing to appear without good cause would result in dismissal. Under (b)(1)(ii), if the prior notice didn't include that warning, the ALJ has to send you a 10-day notice asking for an explanation before dismissing. Either way, the good cause exception in (b)(2) is your defense.

The (b)(2) Good Cause Standard

The text of 20 CFR 404.957(b)(2) is worth quoting because of how flexible it is. When deciding whether you had good cause or good reason for not appearing, SSA considers any physical, mental, educational, or linguistic limitations including any lack of facility with the English language you have. The rule is explicit that disability impairments themselves can be the reason you missed the hearing.

Common good cause situations and the documentation that wins them:

The standard isn't whether you had a perfect reason. It's whether you had any reason that a reasonable person, considering the impairments in the record, could call good cause. The bar is lower than most claimants think.

How to Request the ALJ Vacate a Failure to Appear Dismissal

HALLEX I-2-4-40 is the internal SSA guidance on vacating dismissals. The procedure is straightforward but timing matters.

1. Read the dismissal order carefully. Note the date you got the notice and the subsection cited.
2. Calendar 60 days from receipt under 20 CFR 404.960. SSA presumes 5 days from mail date for receipt, so your actual filing window is usually 65 days from the dismissal letter date.
3. Draft a written request to vacate the dismissal. Address it to the same hearing office that issued the dismissal. Reference the docket number and dismissal date.
4. State the good cause grounds with specificity. Attach all supporting documentation. Cite 20 CFR 404.957(b)(2) and 20 CFR 404.960 explicitly.
5. Ask for the dismissal to be vacated and the hearing request reinstated. If you want a different hearing modality (video, in-person), say so.
6. Submit through ERE if you have rep access, or by certified mail with return receipt if you don't. Keep proof of filing.

The ALJ has authority under 20 CFR 404.960 to vacate the dismissal and reinstate the hearing if good cause is shown. No Appeals Council action is needed if the ALJ grants the vacate. If the ALJ denies the vacate, you have 60 days to file an Appeals Council request.

Res Judicata Dismissals Under 404.957(c)(1)

The res judicata ground is the most legally complicated of the 404.957 dismissals. It applies when SSA has made a previous determination or decision on the same facts and the same issue or issues, and that previous determination became final by administrative or judicial action.

Three elements have to all be present for res judicata to bar a new claim:

1. Same facts. The underlying medical, vocational, and personal facts have to be essentially the same as the prior decision.
2. Same issue or issues. The legal question (entitlement, disability onset, RFC, etc.) has to be the same.
3. Prior decision was final. The prior denial wasn't appealed in time, or all appeals are exhausted.

How to attack each element:

Same Facts: Show Worsening or New Diagnosis

If your condition has worsened since the prior decision, the facts aren't the same. New treating records, new diagnoses, new imaging, new specialist opinions, and new functional capacity evaluations all matter here. A new MRI showing progression of a lumbar condition isn't the same fact pattern as the prior denial. Document worsening with dates that postdate the prior final decision.

Same Issue: Different Time Period or Different Title

If your new claim covers an unadjudicated period, the issue isn't the same. Under AR 24-1(6) and the Earley standard, refiled claims for a different period get fresh review with prior findings considered as evidence. That's a distinct doctrine from the res judicata bar, but it points to the same defense: if the new claim is for a different period, res judicata doesn't apply.

Cross-title situations also help. A prior Title II SSDI denial doesn't bar a new Title XVI SSI claim under res judicata because the entitlement requirements differ. The factual overlap doesn't translate to a same-issue finding.

Not Final: Pending Appeal

If the prior decision is still pending Appeals Council review or federal court review, it's not final, and res judicata can't apply. This is rare in practice because most claimants don't file two overlapping claims, but it sometimes comes up when a represented claimant has a federal court remand pending and files a protective new application at the same time.

Reopening as an Alternative

If the prior decision really did adjudicate the same facts and issue, your remaining option is reopening under 20 CFR 404.987 through 404.989. Reopening rules let you ask SSA to revisit a prior final decision within 12 months for any reason (404.988(a)), within 4 years for good cause (404.988(b)), or at any time for fraud or specific errors (404.988(c)). Reopening is harder than fresh adjudication but easier than fighting a res judicata dismissal head-on.

No Right to a Hearing Under 404.957(c)(2)

This ground rarely shows up in standard SSDI cases. It applies when the claimant doesn't actually have a right to a hearing under 20 CFR 404.930, usually because the issue being raised isn't subject to ALJ review (for example, when the matter has already been finally decided or doesn't involve an initial determination subject to hearing). If you got a 404.957(c)(2) dismissal, the first step is to confirm whether 404.930 actually applies. Sometimes hearing offices use this ground in error when the right ground is one of the others.

Untimely Hearing Request Under 404.957(c)(3)

Under 20 CFR 404.933(b)(1), you have 60 days from receipt of the reconsideration determination to file a request for hearing. If you miss that deadline and no extension is granted under 404.933(c), the ALJ can dismiss for untimely filing.

But 20 CFR 404.911 lists good cause reasons for late filing that the ALJ has to consider before dismissing:

• Serious illness that prevented filing
• Death or serious illness in the immediate family
• Important records lost or destroyed (fire, theft, natural disaster)
• Education or English language limitations that affected understanding of the deadline
• Written notice not received
• Mental impairment that affected ability to act on the deadline
• Reliance on incorrect information from SSA
• Any other unusual or unavoidable circumstances that prevented timely filing

If any of these apply, the ALJ should grant an extension under 404.933(c) and accept the late hearing request. If the dismissal already went out, you can file a request to vacate under 404.960 citing the 404.911 good cause factors.

Claimant Death Under 404.957(c)(4)

This one is more about administrative logistics than substantive law. If the claimant dies while the hearing request is pending and no information about a substitute party reaches SSA within a reasonable time, the ALJ can dismiss.

The dismissal will be vacated if another person whose rights might be adversely affected by the dismissal files a substitution request within 60 days of the notice. Spouses and dependent children of a deceased SSDI claimant typically have rights to underpayments of past-due benefits under 20 CFR 404.503, so substituting in is usually possible.

Practical note: the 60-day window starts when the dismissal notice is sent, not when the family realizes the dismissal happened. If you're a surviving family member dealing with a parent or spouse's pending SSDI case, get in touch with the hearing office immediately to confirm the case status. Don't assume the case just goes away when the claimant dies.

Procedural Rules: HALLEX I-2-4-25 and I-2-4-40

HALLEX is SSA's internal manual for hearings and Appeals Council procedure. Two HALLEX sections govern 404.957 dismissals:

• HALLEX I-2-4-25 sets the procedure for issuing a dismissal. It requires the ALJ to make findings on the dismissal grounds, give the claimant notice, and document the file properly.
• HALLEX I-2-4-40 sets the procedure for vacating a dismissal. It requires the ALJ to consider any good cause showing under 404.957(b)(2) or 404.911 and to make findings on whether good cause has been established.

If the ALJ skipped procedural steps under HALLEX, that itself can be a ground for Appeals Council remand. The AC reviews HALLEX violations as procedural errors, especially where the violation affected the outcome of the dismissal decision.

Appeals Council Review of Dismissals Under 404.967

If the ALJ won't vacate, your next stop is the Appeals Council. AC review of a dismissal isn't identical to AC review of a hearing decision, but the same general procedure applies under 20 CFR 404.967. You file an HA-520 (or the new combined form, where applicable) within 60 days of the dismissal or the ALJ's denial of your vacate request.

The AC has authority to vacate the dismissal and remand for hearing if it finds that the ALJ:

• Misapplied the dismissal grounds (cited the wrong subsection of 404.957)
• Ignored evidence of good cause under 404.957(b)(2) or 404.911
• Failed to follow HALLEX I-2-4-25 or I-2-4-40 procedural requirements
• Made factual findings unsupported by the record
• Violated due process protections (notice, opportunity to be heard)

AC remand patterns for dismissals are similar to AC remand patterns for hearing decisions. See HALLEX I-3-3 Appeals Council Remand Standards for the broader framework.

Federal Court Review Is Mostly Blocked: Califano v. Sanders

This is the part most claimants and many representatives miss. The Supreme Court held in Califano v. Sanders, 430 U.S. 99 (1977), that an SSA dismissal generally is not a final decision under 42 U.S.C. 405(g). Without a final decision, federal courts don't have subject matter jurisdiction over the dismissal itself.

That's a hard rule. If you lose at the AC level, you usually can't file a federal court complaint to fight the dismissal. The narrow exception is when the dismissal raises a colorable constitutional claim, like a due process violation (you weren't given notice, you weren't given an opportunity to be heard before the dismissal was issued, or the procedure used was fundamentally unfair). The Supreme Court left that exception open in Sanders, and federal circuits have applied it narrowly.

The practical consequence: you have to win at the agency level. The vacate request to the ALJ under 404.960 and the Appeals Council request under 404.967 are usually your only real opportunities to fix the dismissal. Don't treat them as procedural formalities. They're your case.

Worked Examples

Example 1: Maria, Texas, Hospitalization on Hearing Day

Maria had an SSDI hearing scheduled for March 15. She was admitted to the ER on March 14 with a hypertensive crisis and was hospitalized until March 17. She didn't call the hearing office because she was unconscious and intubated. The ALJ dismissed under 404.957(b)(1)(i).

Maria's representative filed a vacate request under 404.960 within 30 days. The filing included the ER admission records, the discharge summary, and a treating physician statement that Maria couldn't have notified the hearing office. The good cause showing was clear under 404.957(b)(2). The ALJ vacated the dismissal and rescheduled the hearing. Maria won at the rescheduled hearing.

Example 2: David, California, Untimely Hearing Request

David got his reconsideration denial on June 1. The 60-day deadline to file a hearing request was August 1. David was dealing with a major depressive episode and didn't file until October 15. The ALJ dismissed under 404.957(c)(3) for untimely filing.

David's representative filed a vacate request citing 404.911(b) (mental impairment that prevented timely action). The filing included treating psychiatrist records covering the period from June through October, hospital records from a brief mental health admission in July, and a statement from David explaining how the depression affected his ability to act on the deadline. The ALJ granted the extension under 404.933(c) and vacated the dismissal. The case proceeded to hearing.

Example 3: Robert, Florida, Res Judicata Dismissal

Robert had an SSDI claim denied at hearing in 2022 for an alleged onset of January 2020. He filed a new claim in 2025 for an alleged onset of February 2023. The ALJ dismissed the new claim under 404.957(c)(1), citing the 2022 denial as res judicata.

Robert's representative filed a vacate request arguing the new claim was for an unadjudicated period (the 2022 ALJ decision only adjudicated through the date of decision, leaving February 2023 onward open) and that Robert's medical condition had worsened (new diagnoses of severe COPD and CHF documented in 2023-2024). The ALJ vacated the res judicata dismissal and treated the new claim as a refiled claim governed by AR 24-1(6). The case went to hearing on the merits.

Example 4: Elena, New York, Withdrawal Reconsidered

Elena's representative withdrew her hearing request under 404.957(a) because they thought a new application would be stronger. After the dismissal was issued, Elena's family realized the withdrawal cost her about 8 months of protected filing date and roughly $14,000 in retroactive benefits. Her representative filed a vacate request under 404.960 within the 60-day window, arguing the withdrawal was made without adequate explanation of the consequences.

The ALJ vacated the dismissal because the 60-day vacate window was still open. The hearing was rescheduled. This isn't a guaranteed outcome (withdrawals are generally treated as voluntary and binding), but a timely vacate request can sometimes succeed when the consequences weren't clearly explained.

State-by-State Patterns in 2026

Dismissal rates and ALJ practices vary significantly by hearing office. Patterns we're tracking in 2026:

• California Los Angeles and Oakland hearing offices have higher than average failure-to-appear dismissal rates but also have high vacate rates when good cause is properly documented.
• Texas Dallas and Houston ODARs have high res judicata dismissal rates, often based on prior denials that the new ALJ assumes cover the new period. Push back with clear date documentation.
• Florida Miami and Tampa hearing offices have been aggressive on untimely hearing request dismissals. The 404.911 good cause factors get less weight than they should. Detailed documentation is essential.
• New York hearing offices tend to be more accommodating on vacate requests when good cause is documented but slower on processing the vacate request itself.
• Pennsylvania Pittsburgh and Philadelphia offices have a mix of strict and permissive practice. Pre-vacate strategy matters here.

Practical Checklist If You Just Got a Dismissal Notice

1. Read the notice carefully. Identify the subsection of 404.957 cited.
2. Calendar 60 days from receipt for the vacate window under 404.960.
3. Calendar 60 days from receipt for the Appeals Council deadline under 404.967 (run in parallel).
4. Gather all documentation supporting good cause: medical records, transportation records, family records, language records, address records.
5. If the dismissal is for failure to appear, draft the vacate request citing 404.957(b)(2) good cause factors.
6. If the dismissal is for untimely filing, draft the vacate request citing 404.911 good cause factors.
7. If the dismissal is for res judicata, draft the vacate request attacking same-facts, same-issue, or finality.
8. File the vacate request with the hearing office. Keep proof of filing.
9. If the ALJ denies the vacate, file the Appeals Council request within 60 days of the denial.
10. Track every deadline. Don't let any window close without action.

The Bigger Strategic Picture

404.957 dismissals look like the end of your case, but they're usually not. The 60-day vacate window under 404.960 is the most important deadline in dismissal practice because it gives the ALJ the authority to fix the dismissal without Appeals Council involvement. ALJs grant vacate requests more often than claimants assume, especially for failure to appear where good cause is documented.

The harder dismissals are res judicata under (c)(1) and untimely filing under (c)(3) without good cause. Those need substantive defenses, not just procedural fixes. Build the substantive defense in your vacate request. If the ALJ denies, the same substantive defense goes to the Appeals Council, and the same record gets reviewed.

The harder reality is that federal court isn't going to save you under Califano v. Sanders. You have to win at the agency level. Treat the vacate request and the Appeals Council request as if they were the merits hearing itself, because for a dismissed claim, they effectively are.

Bottom Line

20 CFR 404.957 dismissals are recoverable in most cases. Failure to appear dismissals can be vacated under 404.960 with a good cause showing under 404.957(b)(2). Untimely filing dismissals can be vacated with a 404.911 good cause showing. Res judicata dismissals can be attacked by showing the new claim covers an unadjudicated period or that the underlying facts have changed. Claimant death dismissals can be reversed by a substitution request within 60 days.

What you can't do is sit on the dismissal and hope it goes away. The 60-day clocks under 404.960 and 404.967 run fast. Federal court review under Califano v. Sanders isn't going to be an option for most claimants. The fix has to happen at the ALJ or AC level, and it has to happen on time.

If you got a 404.957 dismissal, calendar the deadlines today. Build the good cause record. File the vacate request. Preserve the Appeals Council window. That's how dismissals get reversed and cases get back on track.
