For many people, working is more than earning a paycheck. This is how they support their families, pay their bills, and maintain a sense of independence. However, when an illness or injury prevents them from working, uncertainty can set in.
Fortunately, Social Security Disability Insurance (SSDI) can provide some financial relief. But what is SSDI and who qualifies in Tennessee?
This program gives monthly benefits to eligible workers with medical conditions that prevent them from maintaining substantial employment. But qualifying is not an automatic process, even if you have a serious diagnosis. Here is whether SSDI may be an option for you and what steps you may need to take.
What Is Social Security Disability Insurance?
Social Security taxes taken out of your paychecks fund disability benefits for eligible workers who can no longer maintain employment because of a qualifying medical condition.
The Social Security Administration runs the program and determines who qualifies. Unlike SSI, SSDI is not a needs-based program and does not impose a savings or asset limit. However, earnings from work can affect whether you qualify. With this program, eligibility depends on your work history and whether your medical condition meets Social Security’s definition of disability.
If you are approved, you can receive monthly payments based on your previous earnings. For someone who has had to step away from work unexpectedly, that income can make a huge difference in your life.
Do You Qualify?
Unfortunately, you don’t automatically qualify for SSDI because you’ve been diagnosed with a serious illness or injury. Social Security will look at both your work history and how your condition affects your ability to earn a living.
In these cases, you must meet two important requirements.
You Must Have Enough Work Credits
Since SSDI is based on your work history, you must have worked in jobs covered by Social Security and earned enough credits to qualify. The number of credits depends on your age when your disability began.
Many adults need 40 work credits, including 20 earned during the 10 years immediately before becoming disabled. Younger workers may qualify with fewer credits because they have less time to build their work history.
In 2026, you earn one work credit for every $1,890 in covered earnings, up to a maximum of four credits per year.
Your Medical Condition Must Meet Social Security’s Definition of Disability
Social Security doesn’t base its decision on your diagnosis alone. It also evaluates the medical evidence and how your condition affects your ability to work and whether you can reasonably adjust to another type of employment. Your condition must:
- Prevent you from engaging in substantial gainful activity.
- Keep you from performing your previous work or adjusting to other work based on your medical limitations, age, education, and experience.
- Have lasted, or be expected to last, at least 12 consecutive months or result in death.
A temporary injury or condition that only partially limits your ability to work won’t meet the SSDI standard.
What Medical Conditions Qualify for SSDI?
Social Security maintains a Listing of Impairments. This includes medical conditions that meet its disability standards. Some conditions that may qualify include:
- Back and joint conditions
- Neurological disorders
- Heart conditions
- Serious illnesses
- Mental health conditions
Keep in mind that two people can have the same diagnosis but experience very different limitations. One person may be able to continue working, while another may struggle with basic job responsibilities because of chronic pain, fatigue, mobility issues, or difficulty concentrating.
Your medical documentation is important. Treatment records, diagnostic testing, medication history, and information from your healthcare providers can help Social Security understand how your condition affects your everyday life and ability to work.
You may still qualify even if your condition does not meet or medically equal a listed impairment, if your limitations prevent you from performing past work or adjusting to other work under Social Security’s rules.
