How Does SSA Decide Disability? The 5-Step Process

Social Security decides every adult disability claim by asking five questions in a fixed order: are you working above the earnings limit, is your impairment severe, does it meet or equal a listing, can you do your past work, and can you do any other work. A claim stops as soon as one answer settles it, so many are decided before the last step. The same five steps apply to SSDI, to adult SSI, to disabled adult children and to disabled widows and widowers.

Social Security’s own data show where claims end. Among disabled workers who applied in 2019, the most common reason for a final medical denial was that the person could adjust to other work, at step five, followed by a finding that the impairment was not severe, at step two. Approvals were split mainly between meeting or equaling a listing at step three and the medical-vocational analysis at step five.

Watch out: The “Step 4 of 5” you may see when checking your claim status online is a progress tracker, not step four of this evaluation. People who check their status report messages such as a representative having started a final review to make sure they still meet the non-medical rules. It says nothing about whether you passed the medical steps.

Where claims are decided

These figures come from Social Security’s annual statistical report and cover final decisions on 2019 applications from disabled workers, a year in which nearly every case has run through its appeals:

The remaining shares are cases where disability had already been established or the basis was not recorded, and denials for other reasons such as insufficient medical evidence or failure to cooperate. The figures do not include SSI-only claims.

Step 1: Are you working above the earnings limit?

If you are doing substantial gainful activity, your claim is denied no matter how serious your condition is. In 2026 that generally means earnings averaging more than $1,690 a month, or $2,830 if you are blind; in 2027 the limits are $1,770 and $2,950. This step is handled by the Social Security office before any medical review. Earnings below the limit do not end the claim, but work while you apply can still be weighed later as evidence of what you can do, and work you had to stop within six months because of your condition can be treated as an unsuccessful work attempt.

Step 2: Is your impairment severe and long-lasting?

From this step on, the state disability agency makes the medical decisions. It first asks whether you have a medically determinable impairment, which must be shown by objective medical evidence, such as examination findings, imaging or lab results, from an acceptable medical source. Your description of symptoms, a diagnosis or a doctor’s opinion cannot establish the impairment on its own, so a thin treatment history can end a claim early.

The impairment must then be severe, meaning it significantly limits your ability to do basic work activities: physical functions such as walking, standing, sitting, lifting, reaching and handling; seeing, hearing and speaking; understanding and remembering simple instructions; using judgment; responding to supervisors, co-workers and usual work situations; and dealing with changes in a routine. Impairments are considered together, so several conditions that are each minor can be severe in combination.

It must also meet the duration requirement: it has lasted or is expected to last at least 12 continuous months, or is expected to result in death. Two unrelated conditions that each last less than 12 months cannot be added together to meet it. Your age, education and work history play no part at this step.

Step 3: Does it meet or equal a listing?

Social Security’s Listing of Impairments, often called the Blue Book, describes conditions with specific medical criteria. If your records satisfy every criterion of a listing and the duration requirement, you are found disabled without any look at your work history or age. This is the most direct route to approval, and it accounted for nearly a third of allowances.

An impairment can also equal a listing in three ways: a listed condition missing a required finding but with other findings of equal medical significance, an unlisted condition whose findings are as significant as those of a closely analogous listing, or a combination of impairments that together equal one. Some of the conditions that most often qualify meet a listing at this step, and conditions on the compassionate allowances list are decided quickly at this step.

Between steps 3 and 4: your residual functional capacity

If your claim is not decided at step three, Social Security assesses your residual functional capacity, the most you can still do on a sustained basis, 8 hours a day, 5 days a week. The same assessment is used at both remaining steps, so it shapes almost every claim that goes past the listings.

Step 4: Can you do your past work?

Social Security compares your RFC with your past relevant work: jobs you did in the 5 years before the decision that paid at the substantial gainful activity level and lasted long enough for you to learn them. A job that started and ended in fewer than 30 calendar days does not count. The comparison is made both with how you actually did the job and with how it is generally done in the national economy, so being unable to do your particular version of a job is not enough if you can do it as it is usually performed.

A job title is rarely enough for this comparison, which is why Social Security asks for your duties, hours, pay, tools and equipment, the weight you lifted, how long you sat, stood and walked, how much supervision you had and the conditions you worked in. Vague descriptions can make a heavy job look light. If Social Security lacks enough information about your past work, it may skip to step five and decide the claim there, but only if that would lead to a denial; when step five might favor you, it must make the step four finding.

Step 5: Can you adjust to other work?

At the last step, Social Security combines your RFC with your age, education and work experience to decide whether you can adjust to other work that exists in significant numbers in the national economy. Here the responsibility shifts: to deny the claim, Social Security must provide evidence that such jobs exist, usually through its vocational rules or a vocational expert.

Age matters more the older you are. The regulations use four categories:

• Younger person: under 50, where age is generally not considered a serious barrier, although people 45 to 49 are treated as more limited in some situations.
• Closely approaching advanced age: 50 to 54.
• Advanced age: 55 and older, where age significantly affects the ability to adjust.
• Closely approaching retirement age: 60 and older, with special rules.

Social Security does not apply these categories mechanically when you are within a few days to a few months of the next one and the older category would lead to approval. Education is measured in categories too, from illiteracy and marginal education, generally 6th grade or less, through limited education and higher levels, although your actual abilities count more than the grade you finished if the evidence shows a difference. For people 50 and older, the medical-vocational guidelines, the grid rules, can decide the case directly from these factors.

Two profiles lead to approval at this step regardless of other jobs: someone with no more than a marginal education who did only arduous unskilled physical labor for 35 years or more and can no longer do it, and someone 55 or older with a limited education or less and no past relevant work.

Children’s claims and benefit reviews use different steps

Children’s SSI claims use three steps: whether the child is working above the earnings limit, whether the impairment is severe, and whether it meets, medically equals or functionally equals the listings. There is no residual functional capacity or vocational step.

People already receiving benefits are reviewed under a different sequential process, the continuing disability review, which focuses on whether their condition has medically improved.

Using the steps to read a denial

Your denial notice explains the basis for the decision, and matching it to a step tells you what evidence to add when you appeal. A step two denial calls for objective test results and treatment records that show the condition and its effects. A step three question calls for the specific findings in the listing. A step four or five denial usually comes down to the RFC and the description of your past work, so detailed work history and a medical source statement from your doctor matter most, at appeal and in the original application.
