Understand the SSDI Definition of Disability
Having a diagnosis alone doesn’t automatically qualify someone for SSDI. Social Security generally
evaluates whether a medically determinable impairment prevents substantial gainful activity and meets
the program’s duration requirements.
Focus on functional limitations, not just the diagnosis.
Document why you cannot perform your past work.
Be prepared to explain why your condition affects your ability to work consistently.
This is one of the most important concepts to understand before applying. The question isn’t simply
whether you’re sick or injured; it’s how your medically documented condition affects your ability to
perform work-related activities.
