SSA's Definition of Disability

To qualify for SSDI, your condition must:

• Prevent you from performing substantial gainful activity (SGA)
• Be medically determinable and backed by clinical evidence
• Last or be expected to last for at least 12 months or result in death

Conditions That Qualify for SSDI

The SSA maintains a list called the Listing of Impairments (often referred to as the “Blue Book”), which includes medical conditions that are considered severe enough to automatically qualify for SSDI—if certain criteria are met.

Here are some examples of qualifying conditions across various categories:

Musculoskeletal Disorders

• Degenerative disc disease
• Spinal disorders
• Joint dysfunction
• Fractures of the limbs or pelvis that do not heal properly

Neurological Disorders

• Epilepsy
• Multiple sclerosis (MS)
• Parkinson’s disease
• Cerebral palsy
• Traumatic brain injury

Mental Disorders

• Major depressive disorder
• Bipolar disorder
• Schizophrenia
• Anxiety disorders
• Autism spectrum disorder

Cardiovascular Conditions

• Congestive heart failure
• Coronary artery disease
• Peripheral artery disease
• Recurrent arrhythmias

Respiratory Conditions

• Chronic obstructive pulmonary disease (COPD)
• Cystic fibrosis
• Asthma (when severe and persistent)
• Pulmonary fibrosis

Immune System Disorders

• HIV/AIDS
• Lupus
• Rheumatoid arthritis
• Inflammatory bowel disease (IBD)

Cancer

• Leukemia
• Breast cancer
• Lung cancer
• Pancreatic cancer
• Any cancer that is advanced or terminal

Other Conditions

• Chronic liver disease
• Kidney disease requiring dialysis
• Vision or hearing loss (meeting SSA standards)
• Diabetes with severe complications

Even if your condition is not listed in the Blue Book, you may still qualify if your limitations prevent you from performing any kind of work on a consistent basis.

What You Need to Prove

You must demonstrate that:

• Your diagnosis is documented by a qualified medical professional
• Your condition limits your ability to perform daily activities and any form of work
• You’ve received ongoing treatment, and your condition has not improved enough for you to return to work
• You meet the work credit requirements for SSDI based on your employment history

Medical Evidence Is Critical

The strength of your medical documentation can make or break your SSDI claim. You’ll need:



• Medical records and diagnostic tests (X-rays, MRIs, lab results)
• Treatment history
• Doctor’s notes outlining your functional limitations
• Statements from treating physicians explaining how your condition impacts your ability to work
