Understanding Social Security Disability: Eligibility & Requirements
What is Social Security Disability?
Social Security Disability Insurance (SSDI) is a federal program managed by the Social Security Administration (SSA) designed to provide monthly financial benefits to individuals who are unable to work due to a qualifying disability. Unlike Supplemental Security Income (SSI), SSDI is based on work history and payroll contributions through FICA taxes.
Who Qualifies for Social Security Disability?
To qualify for SSDI, applicants must meet two primary requirements:
- Medical Eligibility: A medically determinable physical or mental impairment that is expected to last at least 12 months or result in death.
- Work History Requirements: Sufficient work credits earned through prior employment.
What Qualifies as a Disability Under SSA Guidelines?
The SSA uses a strict definition of disability. According to the SSA, a qualifying disability must:
- Prevent the individual from performing substantial gainful activity (SGA)
- Be expected to last at least 12 continuous months or result in death
- Be supported by objective medical evidence
The SSA maintains a list of impairments known as the Blue Book, which includes both physical and mental disorders that may qualify for SSDI if certain criteria are met. Examples include:
- Musculoskeletal disorders
- Neurological conditions (e.g., epilepsy, MS)
- Cardiovascular diseases
- Mental disorders (e.g., depression, bipolar disorder, PTSD)
- Cancer and immune system disorders
Even if your condition is not listed, you may still qualify if it significantly limits your ability to work.
Work Credit Requirements for SSDI
To qualify for SSDI, you must have earned enough work credits. You earn one credit for every $1,730 of wages or self-employment income (2024 rate), up to a maximum of four credits per year.
- Typically, you need 40 work credits, 20 of which must have been earned in the last 10 years.
- Younger applicants may need fewer credits. For example:
- Under age 24: 6 credits earned in the 3 years before disability
- Ages 24-31: Must have worked at least half the time since turning 21
The SSA will evaluate your work history to confirm that you meet the criteria.
Medical Eligibility and Documentation
You’ll need extensive medical evidence to support your SSDI claim. This includes:
- Medical records from treating physicians
- Diagnostic test results (MRIs, bloodwork, X-rays, etc.)
- Medication history
- Mental health evaluations (if applicable)
The SSA may also require you to attend a Consultative Examination (CE) if your medical documentation is insufficient.
A strong medical record is critical. It's helpful if your doctors provide detailed notes on:
- Your diagnosis
- Functional limitations
- Prognosis
- How the condition affects your ability to work
How Long Must a Disability Last to Qualify?
The SSA only approves benefits for disabilities expected to last at least 12 months or result in death. This requirement eliminates short-term injuries and illnesses from SSDI eligibility.
If your condition improves and you can return to work, your benefits may be stopped. However, SSDI does offer trial work periods that allow you to test your ability to work without immediately losing your benefits.
Who is NOT Eligible for SSDI?
You may be ineligible for SSDI if:
- You do not have enough work credits
- Your disability is not severe enough to prevent SGA
- Your condition is short-term or expected to improve quickly
- You are already receiving early retirement benefits
- Your disability resulted from criminal activity or occurred while incarcerated
Also, individuals engaged in substantial gainful activity (SGA) at the time of application (earning more than $1,550/month in 2024) are generally disqualified.
