SSDI Glossary of Terms
Disability Benefits
You can get disability benefits if you:
- Are under full retirement age
- Have enough Social Security work credits
- Have a severe medical impairment (physical or mental) that's expected to prevent you from doing "substantial" work for a year or more, or have a condition that is expected to result in death
Family Benefits
When you're eligible for retirement or disability benefits, the following people may receive benefits on your record:
- Spouse if he or she is at least 62 years old (or any age caring for an entitled child under age 16)

- Children age 18 or older but disabled

Date of Onset
Your "date of onset" is considered the first day you are unable to work because of your disability. The date of onset may or may not be the same as the date you were diagnosed. Applicants usually use the day they last worked as the date of onset.
Month of Entitlement
Your "month of entitlement" to SSDI will be that month which is five full months following your last day of work (your sixth month of disability).
Back Payment
if your disability began more than six months before you applied for SSDI, you may be eligible for "back benefits." Applications for SSDI can be retroactive only up to 12 months.
Family Maximum
The maximum amount of benefits payable to an entire family on any one worker's record.
Supplementary Security Income pays benefits based on financial need.
Appeal

If you disagree with their decision, you have the right to appeal it (ask them to review your case). If their decision was wrong, they will change it.
