Using the diagnosis date
A diagnosis may occur after symptoms and limitations began—or before they became disabling. The legal onset date requires a full chronology.
An essential SSDI timing issue
The date last insured can define the period that must be proven.
SSDI coverage is earned through work credits and does not necessarily remain in force indefinitely after a person stops working. The date last insured is the final date on which a claimant meets the insured-status requirement for disability benefits. In many Title II claims, the claimant must establish disability on or before that date.
A person can be severely disabled today and still face an SSDI denial if the evidence does not establish disability during the insured period. SSI may remain a separate possibility, depending on filing date and financial eligibility.
Evidence for an earlier period
- Contemporaneous primary-care and specialist records
- Older imaging, testing, hospitalizations, and medication history
- Employment records showing reduced attendance, performance, or accommodations
- Statements from medical sources addressing when limitations began
- Later records that reasonably explain the progression of an established condition
- Prior applications, decisions, and earnings history
Common date-last-insured mistakes.
Focusing only on current records
Current severity does not automatically prove the claimant’s capacity years earlier. The earlier period must be connected to the present evidence.
Ignoring work credits
The last day worked and date last insured are related but not necessarily identical.
Abandoning SSI
A claimant who cannot prove disability before the DLI may still have an SSI claim if financial and filing requirements are met.
