Understanding the SSA’s Definition of Disability

To qualify for SSDI or SSI in Tennessee, your condition must meet the SSA’s definition of “disability.” This means:

• You must have a medically determinable physical or mental impairment
• The condition must prevent you from doing substantial gainful activity (SGA)
• It must be expected to last at least 12 months or result in death

Common Conditions That Qualify for Disability in Tennessee

The SSA maintains a “Listing of Impairments”—often referred to as the “Blue Book.” This list includes medical conditions that may automatically qualify if they meet specific criteria.

Here are some examples of qualifying conditions:

Physical Disabilities:

• Musculoskeletal disorders (e.g., back injuries, joint dysfunction)
• Neurological disorders (e.g., epilepsy, multiple sclerosis, Parkinson’s disease)
• Cardiovascular conditions (e.g., chronic heart failure, coronary artery disease)
• Respiratory illnesses (e.g., COPD, asthma, pulmonary fibrosis)
• Cancer (depending on type, severity, and treatment)

Mental Health Disorders:

• Depression and bipolar disorder
• Anxiety disorders (including PTSD)
• Schizophrenia or other psychotic disorders
• Autism spectrum disorder
• Intellectual disabilities

Other Eligible Conditions:

• Chronic kidney disease
• Autoimmune diseases (e.g., lupus, rheumatoid arthritis)
• HIV/AIDS
• Diabetes with complications

Even if your condition isn’t listed in the SSA’s Blue Book, you may still qualify if you can show that it limits your ability to work.

How Disability Claims Are Reviewed in Tennessee

After you apply, your case is reviewed by Tennessee Disability Determination Services (DDS). They’ll evaluate:

• Your medical records
• Work history
• Doctor's opinions
• Whether your condition limits your ability to perform basic work tasks

If your application is denied, you have the right to appeal the decision.
