SSA’s Definition of a Qualifying Disability

The SSA defines a disability as a medical condition that prevents you from engaging in substantial gainful activity (SGA) and is expected to last at least 12 months or result in death. This standard is strict and applies to both physical and mental conditions.

To qualify, your condition must either:

• Meet or equal a medical condition listed in the SSA’s Listing of Impairments, or
• Prevent you from performing any past relevant work or adjusting to other work based on your age, education, and skills.

Common Disabilities That Qualify in Oklahoma

While any condition that meets SSA’s criteria may qualify, the following are common disabilities for which people in Oklahoma are often approved:

• Musculoskeletal Disorders: Back injuries, degenerative disc disease, arthritis, joint dysfunction, and related conditions.
• Mental Health Disorders: Depression, anxiety, PTSD, bipolar disorder, schizophrenia, and autism spectrum disorders.
• Neurological Conditions: Epilepsy, multiple sclerosis, cerebral palsy, Parkinson’s disease, and traumatic brain injuries.
• Cardiovascular Disorders: Congestive heart failure, chronic heart disease, and arrhythmias.
• Respiratory Conditions: COPD, asthma, cystic fibrosis, and pulmonary fibrosis.
• Cancer: Certain aggressive or late-stage cancers may automatically qualify.
• Autoimmune Disorders: Lupus, rheumatoid arthritis, and multiple sclerosis.
• Endocrine Disorders: Diabetes complications, thyroid disorders, and adrenal gland disorders.
• Chronic Pain and Fatigue Syndromes: Fibromyalgia and chronic fatigue syndrome, especially when well-documented.

If your condition is not specifically listed in the SSA’s Blue Book, you may still qualify by proving your symptoms and limitations are equally severe.

Proving a Qualifying Disability

It’s not enough to have a diagnosis—you must prove that your condition seriously limits your ability to work. The SSA will require:

• Detailed medical records, including lab results, doctor’s notes, and treatment history.
• Statements from your treating physician outlining your functional limitations.
• Evidence of work limitations, such as missed work, reduced hours, or job loss due to your condition.

Oklahoma Disability Determination Services (DDS) will review your application, and if more information is needed, they may schedule a consultative examination with an SSA-approved doctor.

Oklahoma SSDI and SSI Eligibility Differences

In Oklahoma, you may qualify for:

• SSDI if you have a sufficient work history and have paid into Social Security.
• SSI if you have limited income and assets, regardless of your work history.

Both programs use the same medical criteria to evaluate disabilities, but financial and work history requirements differ.
