Social Security Disability Criteria: The Five-Step Review

Social Security uses a structured evaluation for most initial adult disability claims. It considers work activity, medical severity, the listings, past relevant work, and other work. The process can stop at a step that resolves the claim; not every applicant reaches a hearing or a vocational decision.

Step 1: Is Your Work Substantial Gainful Activity?

SSA reviews whether you are performing substantial gainful activity, or SGA. It often uses earnings guidelines, but the analysis is not simply a count of hours or take-home pay. Special work conditions, allowable expenses, and unsuccessful work attempts can matter.

Working part time may still be SGA. Earning below a guideline does not itself prove disability. Work incentives for people already entitled to SSDI and the special rules for SSI blindness should not be confused with the ordinary initial disability screen.^[1][2][3]

Step 2: Is There a Severe, Lasting Impairment?

Objective medical evidence must establish a medically determinable impairment. SSA considers whether the impairment or combination of impairments significantly limits basic work activities. Symptoms alone cannot establish the underlying impairment, but their limiting effects matter once it is established.

The disabling impairment generally must last or be expected to last at least 12 continuous months or result in death. This is not a requirement to wait a year before filing. Treatment records should explain the course of the condition and what limitations are expected to continue.^[1][4]

Step 3: Does the Impairment Meet or Equal a Listing?

SSA’s Blue Book contains criteria for particular impairments organized by body system. A diagnosis listed by name is not automatically enough; the required findings and severity must be supported. Medical equivalence requires at least equal medical severity and duration to a listing.

Not meeting or equaling a listing does not end the analysis. SSA ordinarily proceeds to assess residual functional capacity: the most you can still do despite your limitations. A functional assessment considers the relevant evidence and the combined effects of medically established impairments.^[1][5][4][6]

Step 4: Can You Perform Past Relevant Work?

SSA compares residual functional capacity with qualifying past work as actually performed and as generally performed. It generally considers an applicable five-year period, with other requirements about earnings and time to learn the job. Work beginning and ending in fewer than 30 calendar days is not past relevant work.

Give accurate descriptions of duties, lifting, standing, concentration, supervision, and assistance. Being unable to return to one former job as you performed it does not necessarily resolve every applicable past-work comparison.^[7][5]

Step 5: Can You Adjust to Other Work?

If you cannot perform past relevant work, SSA considers other work existing in significant numbers, using residual functional capacity, age, education, and work experience. The issue is the ability to perform work under these rules, not whether a particular employer is hiring nearby.

The medical-vocational guidelines may direct an outcome for some profiles. Other cases need further vocational analysis, especially when nonexertional limitations affect the available work. Age alone, veteran status, or being unable to find a job does not establish disability.^[8][9][5]

Medical Criteria Are Only Part of Eligibility

SSDI also requires the appropriate insured status; SSI has financial and other requirements. Benefits for children, certain family members, or statutory blindness involve additional or different rules. Having a child with a disability or belonging to a veterans’ organization is not an alternative medical test for your own adult claim.

Prepare evidence that addresses the actual decision: provider records, test findings, treatment response, work history, and concrete functional limitations. If denied, use the notice to identify the issue and protect the appeal deadline. The eligibility and application guides explain the separate program and filing steps.^[1][10][11]
