Who Qualifies for Social Security Disability Benefits?

Not every health issue or injury will qualify for SSDI or SSI. This page breaks down Social Security’s strict criteria for disability—what counts as a qualifying condition, the work history you need, and the key factors that determine if you’ll be approved for benefits. If you’re unsure, Cantrell Law can review your case and help you figure out the best path forward.

Basic Eligibility Criteria for SSDI

Work Credit Requirements
You must have worked and paid Social Security taxes long enough to earn “work credits.” Most adults need 40 credits (with 20 earned in the last 10 years) if age 31 or older. Younger applicants need fewer credits. Your recent work history matters—Social Security checks this before even looking at your medical records.


Disability Definition (Medical)
You must have a severe physical or mental impairment that keeps you from “substantial gainful activity” (earning over ~$1,470/month in 2023) for at least 12 months, or is expected to result in death. Part-time work is allowed if earnings are under this threshold, but working above it generally disqualifies you.

Qualifying for SSI (Supplemental Security Income)

SSI does not require work credits but is only for those with very limited income and assets (less than $2,000 for an individual, $3,000 for a couple). SSI is often an option if you haven’t worked enough for SSDI or have never paid into Social Security.

Qualifying Medical Conditions

There’s no official “automatic approval” list, but Social Security’s “Listing of Impairments” (the Blue Book) outlines specific conditions that can qualify—if you meet all the requirements. Examples include advanced cancers, severe heart failure, serious neurological disorders, or certain mental health conditions.



Meeting a Listing:
If your condition matches a listed impairment (with the right medical proof), you are presumed disabled.


Equalling a Listing:
If your condition is just as severe as a listing, even if it’s not identical, you may still qualify.


Residual Functional Capacity (RFC):
If you don’t meet a listing, Social Security evaluates what work, if any, you can still do given your limitations. This includes both physical restrictions (like lifting, standing, sitting) and mental limitations (like concentration or memory).

Factors That Affect Eligibility

  • Age: Applicants over 50 may have an easier time qualifying due to “grid rules” that factor in age, education, and transferable skills.
  • Multiple Impairments: Social Security considers all your health issues together—even if no single condition is disabling, the combination might prevent full-time work.
  • Work History: Consistent work is needed for SSDI, but not SSI.
  • Treatment History: Regular doctor visits and consistent documentation greatly improve your case.

Non-Medical Disqualifiers

You generally cannot qualify if:

  • You continue to work above the substantial gainful activity (SGA) limit
  • You commit fraud or misrepresent your condition
  • You fail to cooperate with SSA requests or miss consultative exams

For SSDI, you must not be working above SGA when you apply—even part-time work over the limit can disqualify your case.

How We Evaluate Your Case

Cantrell Law reviews your medical records and work history to determine if you meet SSDI or SSI requirements. We spot gaps, advise on what evidence is needed, and let you know if you’re likely to qualify or should strengthen your claim before applying. If you’re already on workers’ comp or have multiple impairments, we explain how those impact your eligibility.

FAQ – Disability Eligibility


  • Can I get SSDI for a partial or short-term disability?

    No—SSDI is only for total, long-term disability (lasting at least 12 months or expected to result in death). Short-term or partial disabilities aren’t covered.

  • Do I qualify if I’m 60 and can’t do my old job?

    Possibly. At age 60, Social Security’s rules (the “grids”) often make it easier to qualify if you can’t do your previous work and have limited education or transferable skills.

  • Will Social Security consider all my health problems together?

    Yes—SSA looks at the combined effect of all your impairments, not just one condition.

  • I haven’t been to a doctor—can I still apply?

    You can, but strong medical evidence is crucial. We recommend seeing a doctor for documentation; SSA might send you for a brief exam, but detailed records from your own doctors carry more weight.

  • What if I’m disabled but don’t have enough work credits?

    You won’t qualify for SSDI, but you might for SSI if you have limited income and assets. We help clients figure out the right option.
