Listing 11.04 in 2026: How Social Security Decides Stroke and Vascular Insult Claims Under Paragraph A Aphasia, Paragraph B Motor Disorganization, and Paragraph C Mental Plus Physical Marked Limitation, Plus the 3 Month Rule That Trips Most Files

Published June 20, 2026 by Anthony Albert, Benefits Research Director, Disability Exchange. Sources cited from SSA Blue Book Listing 11.04, 20 CFR Part 404 Subpart P Appendix 1, POMS DI 24580 series, POMS DI 33526.055, and the SSA neurological evidence guidelines under SSR 96-8p.

Stroke is one of the most common neurological reasons people file for Social Security Disability, and it is also one of the most denied at the initial level. The split is brutal. About 795,000 Americans have a stroke each year, and a large share end up with deficits that prevent any return to work. But the initial denial rate on stroke claims still runs above 65 percent at most state DDS offices. The reason almost never has anything to do with whether the stroke happened. It has to do with whether the file documents the right deficits in the right window of time, using the right language, against Listing 11.04.

This is the deep walkthrough. We will break down all three paragraphs of Listing 11.04, the 3 month persistence rule that decides most files, what aphasia has to look like under paragraph A, what disorganization of motor function means under paragraph B, how the marked physical plus marked mental rule under paragraph C actually works, the imaging and clinical records that move the needle, and what to do when the listing falls short. We will cover ischemic stroke, hemorrhagic stroke, subarachnoid hemorrhage, transient ischemic attack, and the residual case angle.

Where Listing 11.04 sits in the rules

Listing 11.04 is part of Section 11.00 of the adult Listing of Impairments, codified at 20 CFR Part 404, Subpart P, Appendix 1. Section 11.00 covers neurological disorders. The full title of 11.04 is "Vascular insult to the brain." SSA uses that phrase as an umbrella term that captures every kind of stroke event. Ischemic strokes from clots, hemorrhagic strokes from bleeds, subarachnoid hemorrhages from ruptured aneurysms, and brainstem strokes all fall under 11.04.

Transient ischemic attack does not qualify under 11.04 by itself because the deficits resolve. But a history of TIA combined with a completed stroke that leaves residual deficits can still meet 11.04 on the basis of the completed event. Vascular dementia from chronic small vessel disease is usually evaluated under 12.02 neurocognitive disorders rather than 11.04 because there is no single discrete vascular event to anchor the listing.

The listing has three independent paragraphs, A, B, and C. You only need to meet one. The 3 month persistence rule applies to all three. That rule says the deficits must persist for at least 3 consecutive months after the insult. We will come back to that rule because it is the single most common reason 11.04 claims get denied at step 3.

The 3 month rule and why it decides most files

SSA generally needs evidence from at least 3 months after the vascular insult to determine whether the listing is met. The reason is medical. The first weeks after a stroke involve cerebral edema, post-stroke inflammation, and an active recovery curve that can mask or exaggerate the permanent deficit. By 3 months, the picture is usually stable enough to predict long-term function. The rule sits inside paragraphs A, B, and C of 11.04 itself, not just the preamble.

This rule cuts two ways. The good direction is that you do not have to wait 12 months to meet the listing. Once you cross the 3 month mark with deficits still present, you can be approved. The bad direction is that DDS will not approve the claim until that 3 month evidence is in the file. If you file 2 weeks after your stroke, expect the claim to sit until enough time passes for a follow-up exam to document persistence.

There is a narrow exception. SSA can approve a stroke claim before the 3 month mark if the evidence of severity is so overwhelming that there is no realistic chance of recovery. Massive middle cerebral artery infarcts with global aphasia and dense hemiplegia, brainstem strokes with locked-in syndrome, and large hemorrhages with persistent coma can all qualify under early adjudication. But these are rare cases. The default is the 3 month wait.

Paragraph A: sensory or motor aphasia with ineffective communication

Listing 11.04A is met when the stroke produces sensory or motor aphasia resulting in ineffective speech or communication, persisting for at least 3 consecutive months after the insult.

Two pieces have to be in place. First, the aphasia has to be sensory (receptive, Wernicke type) or motor (expressive, Broca type). Mixed aphasia counts. Global aphasia counts. Dysarthria alone does not count, because dysarthria is a motor speech production problem rather than a language processing problem. SSA wants language affected, not just articulation.

Second, the aphasia has to result in ineffective speech or communication. The SSA 11.00E1 guidance defines ineffective communication as the inability to use language to communicate effectively in a useful manner. The standard is not perfect speech. It is whether you can be understood and can understand others well enough to function. A speech-language pathology evaluation that documents fluency, comprehension, repetition, and naming deficits using a validated battery like the Western Aphasia Battery or the Boston Diagnostic Aphasia Examination is the strongest evidence.

Because 90 percent of right-handed people have language dominance in the left hemisphere, left middle cerebral artery strokes are the most common path to 11.04A. Right hemisphere strokes can also produce aphasia in left-handed individuals or in those with atypical language dominance, but it is less common. If your stroke was right-sided and you are right-handed, paragraph A is probably not your path. Paragraph B or C is more likely.

Paragraph B: disorganization of motor function in two extremities

Listing 11.04B is met when the stroke causes disorganization of motor function in two extremities, resulting in an extreme limitation in the ability to stand up from a seated position, balance while standing or walking, or use the upper extremities, persisting for at least 3 consecutive months after the insult.

The 11.00D1 guidance defines disorganization of motor function as interference with movement of two extremities (the lower extremities or the upper extremities, or one upper and one lower extremity). The interference can be weakness, paralysis, involuntary movements, ataxia, or sensory disturbance.

The phrase "extreme limitation" is doing a lot of work. SSA defines extreme limitation under 11.00D2 as the inability to stand up from a seated position, balance while standing or walking, or use the upper extremities. The inability to stand up from a seated position means you cannot rise without help or an assistive device. The inability to balance means you cannot maintain upright position on a stable surface and a level floor without holding onto something or using a walker. The inability to use the upper extremities means you cannot independently initiate, sustain, and complete work-related activities involving fine and gross motor movements.

The "two extremities" requirement matters. Hemiparesis from a unilateral stroke usually affects one arm and one leg on the same side. That counts as two extremities. Bilateral lower extremity weakness from a brainstem or bilateral cortical stroke counts. Single-limb deficits do not meet 11.04B no matter how severe.

This is the most common path to approval for hemiparetic stroke patients. A claimant with dense left hemiplegia from a right middle cerebral artery stroke who cannot stand without assistance and cannot use the left arm at all is a clear 11.04B case if the deficits persist at 3 months.

Paragraph C: marked physical plus marked mental limitation

Listing 11.04C is met when the stroke causes a marked limitation in physical functioning and a marked limitation in one of four areas of mental functioning, both persisting for at least 3 consecutive months after the insult. The four mental areas are understanding, remembering, or applying information; interacting with others; concentrating, persisting, or maintaining pace; and adapting or managing oneself.

"Marked" is a lower threshold than "extreme" but higher than "moderate." The 11.00G2 guidance defines marked physical limitation as serious interference with the ability to independently initiate, sustain, or complete work-related physical activities. You can do some physical tasks but not at a level consistent with full-time competitive work.

The 11.00G3a list of physical activities includes standing up from a seated position, balancing while standing or walking, walking on level surfaces, walking on uneven surfaces, climbing stairs, kneeling, crouching, stooping, reaching, handling, fingering, manipulating, and gross and fine motor movements. Marked physical limitation means at least serious interference across this domain.

Marked mental limitation under 11.00G3b means the same level of interference in one of the four mental areas listed above. The mental limitation has to be tied to the stroke. Pre-existing depression that worsens after a stroke can support a 11.04C finding, but DDS will want to see neuropsych testing or a treating psychologist or psychiatrist documenting the post-stroke change.

Paragraph C is the rescue path for claimants who do not meet A or B but have a clear combination of physical deficits and post-stroke cognitive impairment. A patient with mild residual right hemiparesis (not extreme), moderate dysarthria (not aphasia), and significant executive dysfunction on neuropsych testing might not meet A or B but could meet C if the file documents both the physical and mental marked limitations.

The records that win these cases

Strong 11.04 files share a common set of documents. The first is imaging. CT or MRI of the head documenting the location, size, and type of the vascular insult is foundational. Without imaging, DDS cannot confirm the stroke happened. A CT report saying "acute infarct in the left MCA territory with mass effect" or an MRI saying "right basal ganglia hemorrhage with intraventricular extension" tells the adjudicator what they need to know.

The second is the discharge summary from the acute hospitalization. This document captures the immediate neurological deficits, the NIH Stroke Scale score if it was done, and the disposition. NIH Stroke Scale scores above 15 generally predict significant long-term deficits and make 11.04B or 11.04C more likely.

The third is the follow-up neurology visit at the 3 month mark or later. This is the single most important record for 11.04. The note has to describe the residual deficits in functional terms. Strength testing with manual muscle testing grades, gait description, balance testing, speech evaluation, and a clear statement about what the patient can and cannot do.

The fourth is therapy notes. Physical therapy, occupational therapy, and speech-language pathology notes from inpatient rehab, acute rehab, and outpatient sessions all carry weight. Therapists document function in detail because their job depends on tracking functional change. A PT note saying "patient requires moderate assistance of one to transition from sit to stand, ambulates 50 feet with rolling walker and contact guard" is far more useful to DDS than a generic neurology note that says "patient continues to have left-sided weakness."

The fifth is neuropsychological testing if paragraph C is the path. Validated batteries like the WAIS-IV, Trail Making A and B, the Rey Auditory Verbal Learning Test, and the BDAE produce scores that map directly to the four mental functioning areas. A neuropsych report with deficits at or below the 5th percentile in executive function or memory is strong evidence of marked mental limitation.

What if the listing is not met

Many stroke claimants have real, work-preventing deficits that do not quite reach the listing thresholds. They have hemiparesis but can stand without help. They have aphasia but can still get basic ideas across. They have cognitive changes but the deficits are moderate rather than marked. For these claimants, the path is residual functional capacity (RFC) and the medical-vocational rules.

RFC after stroke usually includes some combination of reduced standing and walking tolerance, reduced lifting and carrying capacity, limited reaching and handling on the affected side, limited bilateral fine manipulation, and non-exertional mental limitations like reduced concentration, slowed processing speed, and limited tolerance for complex instructions. A sedentary RFC with a restriction to simple, routine tasks and no fast-paced production requirements often wins under the medical-vocational guidelines, especially for claimants age 50 and over.

The grid rules are decisive here. At sedentary RFC, a claimant who is 50 or older with no transferable skills from past relevant work and no recent education that provides direct entry into skilled work is generally found disabled under Grid Rule 201.14. At light RFC, the same claimant is generally not disabled unless there are additional non-exertional limitations that erode the light occupational base.

For claimants under 50, the medical-vocational grid is far less generous. The case usually hinges on whether non-exertional limitations (cognitive, communication, behavioral) erode the unskilled occupational base enough that no jobs exist in significant numbers. A vocational expert at hearing is critical for these cases.

Worked example: a left MCA stroke claim

Let's run a real-style claim. A 58-year-old former construction supervisor had a left middle cerebral artery ischemic stroke 6 months ago. CT and MRI confirmed the infarct. NIH Stroke Scale at admission was 16. He was discharged to acute rehab for 4 weeks, then home with outpatient PT, OT, and SLP.

At the 3 month follow-up with neurology, he had Broca-type expressive aphasia (fluency 2 out of 10 on a clinical rating, naming 30 percent correct), right hemiparesis with manual muscle testing of 3/5 in the right upper extremity and 4-/5 in the right lower extremity, mild right facial droop, and intact comprehension. He could ambulate with a quad cane for short distances but needed a wheelchair for community mobility. He could not use the right hand for fine motor tasks.

Score it against 11.04. Paragraph A is in play because the expressive aphasia is severe enough that communication is ineffective. The SLP report at 3 months should explicitly say so. Paragraph B is borderline because he can stand and ambulate with a cane, so the "extreme limitation in balance" prong is not met, but the upper extremity prong (cannot use right hand for work activities) is potentially met. Paragraph C is also viable because the aphasia produces marked limitation in interacting with others and the right hemiparesis is at least marked physical limitation.

The strongest path is 11.04A. The case turns on whether the SLP evaluation documents ineffective communication at the 3 month mark. If it does, this is a listing approval. If the SLP report is vague, the path shifts to 11.04C with the cognitive-communication piece as the mental functioning anchor.

State-by-state notes

SSDI is federal, so the listing applies the same way in every state. But DDS decisions are made at the state level, and approval rates vary. Texas, Florida, and Mississippi DDS offices tend to be tougher on stroke claims than California, New York, or Massachusetts. The reason has to do with adjudicator caseloads, training, and local culture around neurological listings.

Hearing-level approval rates are much more even nationally because Administrative Law Judges follow the same federal rules. If your state DDS denies, the appeal to a hearing usually produces a fairer review. Average wait times to hearing in 2026 run 9 to 15 months depending on the hearing office. Plan accordingly.

State-specific Medicaid rules matter for stroke claimants because Medicaid often kicks in faster than SSDI and covers the rehab and therapy that produces the records you need. Massachusetts MassHealth, California Medi-Cal, and New York Medicaid all cover post-stroke rehab generously. Other states are more restrictive on outpatient PT and SLP visit caps.
