Social Security Disability Benefits in Tennessee
Social Security Disability Insurance (SSDI) is a federal program that provides monthly income to people who are unable to work due to a qualifying medical condition. It’s not a handout, it’s a benefit you’ve paid into through years of work and Social Security taxes. If a disability has taken away your ability to earn a living, SSDI exists specifically for situations like yours.
SSDI vs. SSI: What’s the Difference?
There are two federal disability programs administered by the Social Security Administration: Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI). While they’re often mentioned together, they work differently.
SSDI is based on your work history. To qualify, you must have worked long enough and recently enough to have accumulated sufficient work credits—generally earned by paying Social Security taxes over the course of your career. The monthly benefit amount is based on your earnings records.
SSI is need-based and is not tied to your work history. It’s designed for disabled individuals with limited income and assets, including those who haven’t worked enough to qualify for SSDI.
Which Program Applies to You?
The simplest way to determine which program you qualify for is to look at your work history:
| SSDI | SSI |
| Based on work history? | Yes | No |
| Requires Social Security work credits? | Yes | No |
| Income and asset limits? | No | Yes |
| Benefit amount based on earnings record? | Yes | No |
| Qualification without ever working? | No | Yes |
| Medicare eligibility after 24 months? | Yes | No |
| Medicaid eligibility? | No | Yes |
If you’ve worked consistently and paid Social Security taxes, SSDI is likely the program that applies to you. If you have little to no work history or your income and assets fall below SSA thresholds, SSI may be the more relevant path. It’s also possible that you may qualify for both simultaneously, which is more common than most people realize.

Who Qualifies for Social Security Disability?
To qualify for SSDI, you must meet 2 sets of requirements:
Work history requirements: You must have worked enough years and paid enough into Social Security to have earned the required work credits. The exact number depends on your age at the time you became disabled. Generally, you need at least 40 credits, 20 of which were earned in the last 10 years, though younger workers may qualify with fewer.
Medical requirements: The SSA requires that your condition be severe enough to prevent you from performing any substantial gainful activity, meaning you cannot earn more than a threshold amount per month, and that it has lasted or is expected to last at least 12 months, or to result in death.
Meeting both criteria doesn’t guarantee approval. The SSA’s evaluation process is detailed and demanding, and many legitimate claims are denied at the initial stage. Continue reading to learn more about what happens if your claim is denied.
What Medical Conditions Qualify?
The SSA maintains a list of impairments, known as the “Blue Book,” that automatically qualify as disabling if the documented medical evidence meets specific criteria. Conditions covered include:
- Musculoskeletal disorders (back injuries, joint problems, spinal conditions)
- Cardiovascular conditions (heart failure, coronary artery disease)
- Neurological disorders (epilepsy, multiple sclerosis, Parkinson’s disease)
- Mental health conditions (severe depression, bipolar disorder, schizophrenia, PTSD)
- Cancer
- Respiratory illnesses (COPD, chronic asthma)
- Immune system disorders
- Chronic kidney disease and other organ system impairments
If your condition is not on the Blue Book list, you may still qualify. The SSA can find you disabled if your condition (either alone or combined with other impairments) prevents you from doing any work you’ve previously done or any other type of work that exists in significant numbers in the national economy.
The medical documentation supporting your claim is critical either way. The SSA, like insurance companies in injury claims, will not just take your word for it. An experienced disability attorney can help ensure your records accurately reflect the full impact of your condition.
