There is no separate list of conditions for Supplemental Security Income. SSI uses the exact same medical standard as SSDI: the Social Security Administration's Listing of Impairments, commonly called the Blue Book, organized into 14 body system categories. What makes SSI different is everything wrapped around that medical standard. SSI adds a strict income and asset test that SSDI does not have, treats blindness as its own eligibility category with its own rules, and judges children under 18 by a completely different standard that measures functioning across six domains rather than work capacity.
So the honest answer to "which disabilities qualify for SSI" is two answers at once. Medically, the qualifying conditions are the same ones that qualify for SSDI. Practically, a qualifying diagnosis is only half of what SSI requires, and roughly half of denials in this program have nothing to do with medicine at all.
The Two Tests SSI Applies, and Why One of Them Surprises People
Every SSI disability claim gets reviewed twice: once by a state Disability Determination Services examiner who looks only at your medical file, and once by the local Social Security field office that looks only at your money. Failing either one ends the claim.
| Test | What it measures | Applies to SSDI? |
|---|
| Medical (disability) | Does your condition meet or equal a Blue Book listing, or otherwise prevent substantial work for at least 12 months | Yes, identical standard |
| Non-medical (financial) | Countable income below the federal benefit rate, countable resources at or under $2,000 single / $3,000 couple | No |
| Citizenship and residency | US citizen or qualifying non-citizen, living in one of the 50 states, DC, or the Northern Mariana Islands | Partially |
| Work credits | Not required for SSI at all | Required for SSDI |
This is the core distinction between the two programs. SSDI asks whether you paid enough into Social Security through payroll taxes. SSI asks whether you are poor enough to need help right now. If you are weighing which program fits your situation, our breakdown of SSI vs SSDI eligibility differences compares them side by side, and many people qualify for both at the same time.
The Medical Standard: the Same 14 Blue Book Categories
For adults 18 and older, SSI uses Part A of the Listing of Impairments. The listings cover 14 body systems, and each listing spells out the specific test results, clinical findings, or functional limitations that qualify.
| Section | Body system | Representative conditions |
|---|
| 1.00 | Musculoskeletal | Spinal disorders, joint reconstruction, amputation |
| 2.00 | Special senses and speech | Statutory blindness, profound hearing loss, loss of speech |
| 3.00 | Respiratory | COPD, cystic fibrosis, lung transplant |
| 4.00 | Cardiovascular | Chronic heart failure, ischemic heart disease, arrhythmias |
| 5.00 | Digestive | Chronic liver disease, inflammatory bowel disease, short bowel syndrome |
| 6.00 | Genitourinary | Chronic kidney disease requiring dialysis |
| 7.00 | Hematological | Sickle cell disease, bone marrow failure, hemophilia |
| 8.00 | Skin | Severe burns, chronic skin infections, hidradenitis suppurativa |
| 9.00 | Endocrine | Complications of diabetes, thyroid and pituitary disorders |
| 10.00 | Congenital disorders affecting multiple systems | Non-mosaic Down syndrome |
| 11.00 | Neurological | Epilepsy, multiple sclerosis, Parkinson's disease, ALS |
| 12.00 | Mental disorders | Major depression, PTSD, schizophrenia, autism spectrum disorder |
| 13.00 | Cancer | Most malignant neoplastic diseases |
| 14.00 | Immune system | Lupus, HIV, inflammatory arthritis |
We keep the full condition-by-condition breakdown, including the specific medical evidence each listing requires, in our guide to disabilities that qualify for SSDI in 2026. Read that page for the medical details, because for an adult SSI claim the criteria are word for word the same.
Two points matter regardless of which listing applies to you. First, your condition does not have to appear in the Blue Book at all. If your impairment is medically equal in severity to a listing, or if your combined limitations leave no work you can realistically do given your age, education, and past jobs, you can be approved through a medical-vocational assessment instead. Second, the condition must have lasted or be expected to last at least 12 continuous months, or be expected to result in death. A severe but short-term injury does not qualify no matter how disabling it is while it lasts.
Blindness Is Its Own Category, Not Just Another Listing
SSI treats blindness as a separate basis for eligibility, parallel to disability rather than a subset of it. You meet the statutory definition if your central visual acuity is 20/200 or worse in your better eye with the best correcting lens, or if your visual field is limited so that the widest diameter subtends an angle of 20 degrees or less.
The practical advantages are significant:
- No substantial gainful activity test. Social Security does not use the monthly SGA amount to decide SSI eligibility for a person who is blind. For SSDI, the 2026 blind SGA threshold is $2,830 per month compared with $1,690 for non-blind claimants. For SSI, the test simply does not apply, so eligibility continues until you medically recover or fail a non-disability requirement.
- Blind work expenses. Any earned income you spend on costs of working gets excluded from countable income. That covers transportation to work, a guide dog including food and veterinary care, attendant care, work-related equipment, licenses and taxes, and even meals eaten during work hours. The exclusion is broader than the impairment-related work expense rule available to other recipients.
- Separate state supplements. Many states pay a higher supplemental amount to blind recipients than to other disabled recipients.
Our guide to SSI for blind adults in 2026 walks through the documentation an eye specialist needs to provide.
Children Under 18 Are Judged by a Different Standard Entirely
This is the largest difference between SSI and SSDI, and it only exists in SSI, because SSDI requires a work record that a child cannot have.
A child qualifies if a medically determinable physical or mental impairment results in marked and severe functional limitations that have lasted or are expected to last at least 12 months or result in death. Nothing in that standard refers to working. It refers to functioning like other children the same age.
The examiner first checks Part B of the Listing of Impairments, the childhood listings numbered 100.00 through 114.00. If the child's condition does not meet or medically equal a listing, the examiner goes to a step that has no equivalent in adult claims: functional equivalence, which rates the child across six domains of functioning.
| Domain | What is being measured |
|---|
| Acquiring and using information | Learning, reasoning, thinking, remembering, and applying what is learned |
| Attending and completing tasks | Focus, pace, persistence, and finishing age-appropriate activities |
| Interacting and relating with others | Forming relationships, cooperating, communicating, managing conflict |
| Moving about and manipulating objects | Gross and fine motor skills, balance, coordination, dexterity |
| Caring for yourself | Hygiene, feeding, dressing, safety awareness, and emotional self-regulation |
| Health and physical well-being | Cumulative physical effects of the impairment and its treatment, including flare-ups, fatigue, medication side effects, and hospitalizations |
The child functionally equals the listings with either a marked limitation in two of the six domains or an extreme limitation in one. Marked means the impairment seriously interferes with the ability to independently start, sustain, or complete activities. Extreme means it interferes very seriously.
Because this standard is about daily functioning rather than lab values, the strongest evidence for a child's claim often comes from outside the doctor's office: individualized education program documents, 504 plans, teacher questionnaires, school behavior reports, therapy notes, and daycare observations. Our guide to SSI disability requirements for children in 2026 covers what to gather before you file.
At 18, the child is re-evaluated under the adult standard in what Social Security calls an age-18 redetermination. Children approved under the functional equivalence route do get denied at 18 sometimes, because the question changes from functioning to work capacity.
A Qualifying Disability Alone Is Not Enough
Here is where otherwise-eligible people lose their SSI claims. The medical side can be airtight and the field office can still deny.
2026 financial limits
| Rule | Individual | Couple |
|---|
| Federal benefit rate (maximum monthly payment) | $994 | $1,491 |
| Countable resource limit | $2,000 | $3,000 |
| General income exclusion | First $20 of most income per month | $20 per couple |
| Earned income exclusion | First $65 plus half of the remainder | Same |
Countable income is not gross income. Social Security excludes the first $20 of almost any income, then the first $65 of wages plus half of everything above that. Because of those exclusions, an individual with only unearned income such as a pension or child support generally loses SSI eligibility somewhere near $1,014 per month, while someone whose income is all wages can typically earn roughly $2,073 per month before the payment reaches zero. Those figures shift with state supplements and with any exclusions that apply to you.
Resources are the trap people fall into. The $2,000 limit for an individual has not been raised since 1989. It counts cash, bank balances, stocks, bonds, and property you are not living in. It does not count the home you live in, one vehicle, household goods and personal effects, burial funds up to $1,500, or up to $100,000 in an ABLE account. A single bank balance above the limit on the first of the month can suspend payments for that month.
Deeming
For a child, Social Security counts, or "deems," part of the parents' income and resources as the child's own. Deeming is formula-driven rather than a flat cutoff. The agency subtracts a parental living allowance of $994 for one parent in the home or $1,491 for two, plus allocations for other children in the household, plus the standard income exclusions. As a rough guide, a two-parent household with one eligible child and no other children generally stops receiving an SSI payment somewhere above $5,000 per month in wages, and a one-parent household somewhere above $4,100 per month. A similar deeming rule applies between spouses for adult claims. Our page on SSI deeming exceptions explains when parental income stops counting, including after a child has been institutionalized for a full calendar month.
Conditions That Can Get Paid Before the Decision
SSI has an expedited payment route that SSDI does not. If a field office employee finds your allegation highly likely to be approved, you can receive presumptive disability or presumptive blindness payments for up to six months while the medical review continues. If you are ultimately denied, those payments are not treated as an overpayment.
Field offices can make that finding for a defined set of allegations, including:
- Total blindness or total deafness
- Amputation of a leg at the hip
- Down syndrome
- Confinement to bed, or immobility without a wheelchair, walker, or crutches, due to a longstanding condition
- Stroke more than three months in the past with continued marked difficulty walking or using a hand or arm
- Cerebral palsy, muscular dystrophy, or muscle atrophy with marked difficulty walking, speaking, or coordinating the hands or arms
- Intellectual disability or another neurodevelopmental impairment such as autism spectrum disorder
- End-stage renal disease requiring dialysis
- Amyotrophic lateral sclerosis (ALS)
- A terminal illness with a life expectancy of six months or less
Separately, the Compassionate Allowances program flags more than 275 conditions, mostly aggressive cancers, rare diseases, and early-onset neurodegenerative conditions, for fast-track medical review. Compassionate Allowances speeds the decision; presumptive payments start the money early. They are different mechanisms and a claim can use both.
How to Apply for SSI Based on Disability
- Gather your medical evidence. Names, addresses, and phone numbers of every doctor, clinic, and hospital, dates of visits, a current medication list, and test results. For a child, add school records, the IEP or 504 plan, and teacher observations.
- Gather your financial documents. Recent bank statements for every account, proof of income, your lease or mortgage information, and vehicle titles. The field office will verify resources as of the first day of each month.
- Start the application. Adults can begin online at ssa.gov. Child SSI claims start with the online Child Disability Starter Kit and a Child Disability Report, then require a call or appointment to finish the SSI portion.
- Complete the disability report. Form SSA-3368 asks how your condition limits daily activities. Be specific and concrete. "I cannot stand longer than 10 minutes before my back forces me to sit" carries more weight than "I have back pain."
- Sign the medical release. Form SSA-827 lets Disability Determination Services request your records directly.
- Attend any consultative examination. If your file lacks recent evidence, SSA pays for an exam. Missing it is a common reason for denial.
- Appeal if denied. You have 60 days to request reconsideration. Most initial claims are denied, and a large share of approvals happen later in the process at the hearing level.
Frequently Asked Questions
Does SSI have a different list of qualifying disabilities than SSDI?
No. Adult claims under both programs use Part A of the same Listing of Impairments and the same definition of disability. The differences are non-medical: SSI adds income and resource limits and requires no work credits, while SSDI requires work credits and ignores your assets.
Can I get SSI for anxiety, depression, or PTSD?
Yes, mental disorders in section 12.00 are among the most common bases for approval. The listings generally require medical documentation of specific symptoms plus either an extreme limitation in one of four areas of mental functioning or a marked limitation in two. Those four areas are understanding and applying information, interacting with others, concentrating and maintaining pace, and adapting or managing yourself.
My child has autism. Does that automatically qualify for SSI?
No diagnosis automatically qualifies. Autism spectrum disorder appears in the childhood listings, but the examiner evaluates how severely it limits your child's functioning, and the family still has to pass the deeming test on income and resources. Many children with a confirmed diagnosis are denied on finances rather than medicine.
What if my condition is not in the Blue Book?
You can still qualify. The examiner can find your impairment medically equivalent to a listing, or can find that no work exists that you can perform given your residual functional capacity, age, education, and work history. Fibromyalgia, long COVID, and chronic fatigue syndrome have no dedicated listing and are regularly approved on that basis with strong longitudinal records.
How long does my disability have to last to qualify for SSI?
At least 12 continuous months, or it must be expected to result in death. You do not have to wait 12 months to apply. You can file as soon as the condition is expected to meet the duration requirement.
Can I qualify for SSI based on age instead of disability?
Yes. People 65 and older can receive SSI with no disability finding at all, as long as they meet the income, resource, citizenship, and residency rules. The medical standard only matters for applicants under 65.
Does a one-time SSI denial on finances mean I can never qualify?
No. Financial eligibility is evaluated month by month. If your resources drop back under the limit or your income falls, you can reapply. A denial for excess resources says nothing about your medical eligibility.
Figures in this guide reflect 2026 amounts published by the Social Security Administration, including the $994 individual federal benefit rate, the $2,000 and $3,000 resource limits, and the $1,690 and $2,830 substantial gainful activity amounts. Income and asset rules change annually. Verify current amounts with SSA before relying on them, and treat the estimates in this guide as general information rather than legal advice.
