Social Security Disability Insurance (SSDI) is a federal program offering income support to individuals who can no longer work due to a debilitating condition.
With eligibility based largely on previous contributions to the Social Security system and fulfilling certain medical criteria.
This contrasts with Supplemental Security Income (SSI), another type of benefit that targets low-income, disabled, or aged individuals irrespective of their employment history.
Thus making it crucial to comprehend these differences before proceeding with an SSDI lawsuit.
Definition and eligibility requirements
Social Security Disability Insurance (SSDI) is a key federal program that provides financial assistance to people who cannot work due to a disability.
The eligibility for SSDI is determined by the Social Security Administration, and it’s contingent on three main factors: age, disability, and work history.
Applicants must exhibit an inability to perform substantial gainful activity because of their medical condition which should last at least one year or result in death.
Moreover, they must have earned enough credits from their employment history where they contributed to the Social Security trust fund through payroll taxes.
It’s worth noting that long COVID can now be considered as a criterion for disability under Titles II and III of the Americans with Disabilities Act (ADA).

Types of Benefits: Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI)
There are two main types of benefits for people with disabilities under the Social Security program:
- SSDI is a benefit program that provides payments to disabled workers and their dependents.
- To qualify for these benefits, the person must have a sufficient employment history and be unable to engage in substantial gainful activity due to disability.
- The amount of monthly benefits received under SSDI depends on the person’s past earnings.
- SSI is a separate program designed specifically for people with disabilities who have low income and few resources.
- Unlike SSDI, eligibility for SSI is not based on prior work history.
- Instead, it focuses on current income and resource limits.
- Despite being different programs, there are some similarities between SSDI and SSI as they both provide financial support to individuals with disabilities.
