The short answer
Social Security does not keep a list of conditions that qualify automatically. For both SSDI and SSI, an adult must have a medical condition expected to last at least 12 months or to result in death that prevents substantial work, which for 2026 means earning more than $1,690 a month, or $2,830 if you are blind. Its Listing of Impairments, known as the Blue Book, describes conditions in 14 body systems for adults and 15 for children that are severe enough to meet the test on medical grounds alone when their specific criteria are met. Its Compassionate Allowances list, 314 conditions as of August 2026, names conditions such as certain cancers that so clearly meet the standard that decisions are fast-tracked. Many people are approved without meeting a listing: Social Security decides whether their limitations, together with their age, education and work history, rule out their past work and any other work.
Why a diagnosis is only the start
Social Security's definition of disability for adults is the same for SSDI and SSI. You must be unable to do substantial gainful activity because of a medically determinable physical or mental impairment that has lasted, or is expected to last, at least 12 months, or is expected to result in death.
Substantial gainful activity is measured in earnings. For 2026 the line is $1,690 a month, or $2,830 if you are blind; for 2027 it rises to $1,770 and $2,950. Someone earning above it is generally not considered disabled, whatever the diagnosis. Blindness has its own definition: central vision of 20/200 or less in the better eye with correction, or a visual field of 20 degrees or less. Our guide to how Social Security decides you are disabled walks through the full five-step process; this guide focuses on the medical side.
Could you qualify? A quick check
- Duration. Has your condition lasted, or is it expected to last, at least 12 months?
- Work. Are you earning less than the substantial gainful activity limit, or not working at all?
- Severity. Does the condition significantly limit basic activities such as standing, walking, lifting, remembering or concentrating?
- Past work. Does it stop you from doing the jobs you held in recent years?
- Other work. Given your age, education and experience, would it stop you from adjusting to other work?
A yes to all five is the shape of an approved claim. A no to the first two usually ends it, which is why the medical lists below matter only once those are settled.
The Blue Book: conditions by body system
The Listing of Impairments, often called the Blue Book, describes conditions that are severe enough on their own to prevent any gainful activity. Each listing sets specific criteria, such as test results, clinical findings or how often episodes occur. If your medical records show you meet a listing, or a condition equal to one in severity, and you are not working above the earnings limit, Social Security finds you disabled without looking at your age or work history.
| Listing | Body system |
|---|---|
| 1.00 | Musculoskeletal disorders |
| 2.00 | Special senses and speech |
| 3.00 | Respiratory disorders |
| 4.00 | Cardiovascular system |
| 5.00 | Digestive system |
| 6.00 | Genitourinary disorders |
| 7.00 | Hematological disorders |
| 8.00 | Skin disorders |
| 9.00 | Endocrine disorders |
| 10.00 | Congenital disorders that affect multiple body systems |
| 11.00 | Neurological disorders |
| 12.00 | Mental disorders |
| 13.00 | Cancer |
| 14.00 | Immune system disorders |
Children's listings follow the same pattern in 15 body systems, numbered from 100.00, which covers low birth weight and failure to thrive in infants.
Mental health conditions count too
Listing 12.00 covers mental disorders, including depression, bipolar disorder, anxiety disorders, schizophrenia, autism and intellectual disorder. For most of them, Social Security looks beyond the diagnosis to four areas of mental functioning: understanding, remembering or applying information; interacting with others; concentrating, persisting or maintaining pace; and adapting or managing oneself.
That is why records from a therapist or psychiatrist that describe how you function, not only which medication you take, carry so much weight. A mental condition that does not meet the listing can still lead to approval at the later steps, alone or combined with physical conditions.
Compassionate Allowances: the fast track
Some conditions so plainly meet the standard that Social Security can decide a claim with little more than confirmation of the diagnosis. Its Compassionate Allowances list named 314 conditions as of its August 10, 2026, update, after 14 were added that month. They include certain cancers and leukemias, amyotrophic lateral sclerosis (ALS) and early-onset Alzheimer's disease, along with many rare disorders.
There is no separate application. Social Security's systems flag claims that match a listed condition, and the medical records still have to confirm it. More than 1.2 million people with severe disabilities have been approved through the process since it began. The non-medical rules still apply in full: enough work credits for SSDI, and the income and resource limits for SSI.
If your condition is not on any list
Many people are approved without meeting a listing. At the later steps, Social Security decides what you can still do despite your condition, called your residual functional capacity, and compares it with the demands of the work you did in the past. If you cannot do your past work, it asks whether you could adjust to other work, considering your age, education and experience.
Age carries real weight here. The rules become more favorable from age 50 onward, because Social Security accepts that older workers find it harder to move into new kinds of work. And conditions are considered together: several impairments that would not qualify one by one can, in combination, rule out work.
What the evidence has to show
Claims succeed or fail on medical records, not on a diagnosis written on a form. The strongest files show the condition through objective findings, such as imaging, lab results or test scores, and show what it does to daily function over time.
- Name every condition on the application, including mental health conditions and the side effects of treatment.
- List every source of treatment, with dates, so Social Security can request the records.
- Keep up with treatment where you can; gaps in care make a record harder to read.
- Describe limits concretely, such as how long you can stand or how often symptoms stop you from working.
- Ask your doctors for a statement that describes your limits in work terms, such as how long you can sit, how much you can lift or how often you need to rest.
- Attend any exam Social Security arranges, since a missed consultative exam can lead to a denial.
Children and SSI
Children can receive disability benefits through SSI, which has income and resource limits that count the parents' income and resources in most cases. For a child, the medical test is different: the condition must cause marked and severe functional limitations and meet the same duration rule. The children's listings and an assessment of how the child functions compared with other children the same age decide the medical side. Our guide to SSI explains the financial rules, and the SSI calculator estimates a payment.
Common questions
Is there a list of conditions that automatically qualify?
No. The Blue Book lists conditions severe enough to qualify when specific medical criteria are met, and the Compassionate Allowances list speeds up decisions for the most severe. But no diagnosis qualifies by name alone, and the work and income rules still apply.
Can several conditions together qualify?
Yes. Social Security considers the combined effect of all your impairments, physical and mental, so several that would not qualify one at a time can together show that you cannot work.
Can I work while my claim is pending?
You can, but earnings above the substantial gainful activity limit generally mean you are not considered disabled for that period. If you do work, report your earnings, and expect Social Security to weigh them in its decision.
Does a Compassionate Allowances condition mean automatic approval?
No. It speeds up the medical decision, but the records must confirm the diagnosis, and you still have to meet the other rules: enough work credits for SSDI, or the income and resource limits for SSI.

Build the record before you apply
Look up your condition in the Blue Book and on the Compassionate Allowances list, but do not stop there if it is missing; many approvals come at the later steps. Gather your treatment history, then check the other half of the test: whether you have enough recent work for SSDI. The SSDI calculator checks your work record and estimates the payment, and our guide to SSDI back pay explains what an approval pays for the months you waited.
