You had to stop working because of your health, and applying for Social Security Disability Insurance feels like something you can put off until things settle. Waiting is the mistake that costs people their benefits: if you do not pass the recent work test, you must prove that you became disabled before your Date Last Insured. That can be difficult unless you have precise medical records from your doctors.
If you are unsure about your Date Last Insured, obtain your earnings record and benefit statement. The work credits and coverage date determine whether an SSDI application remains available.
An Illustrative Decision Point
Consider a hypothetical applicant whose Date Last Insured passed two years ago but whose current records describe a condition that began much earlier. The present diagnosis does not automatically establish disability during the covered period. The claim may depend on whether treatment notes, testing, work history, and other evidence document the relevant limitations before coverage ended.
Bring the earnings record, benefit statement, application and denial notices, work timeline, and medical records spanning the alleged onset date through the Date Last Insured. Counsel can then verify the coverage date, identify the period that requires proof, and decide which medical and vocational evidence addresses that period. This illustration does not establish insured status or disability.
