Date Last Insured

the last date a worker may meet the insured-status requirement for SSDI

What date last insured means

In disability benefits research, date last insured generally refers to the last date a worker may meet the insured-status requirement for SSDI. Exact meaning depends on the SSA notice, VA record, medical file, appeal level, or payment issue where the term appears.

Why date last insured matters

  • Date Last Insured can affect eligibility, medical evidence, appeal timing, payment amount, back pay, overpayment response, or representative strategy.
  • Ask whether the term appears in a denial notice, medical exhibit, hearing decision, payment letter, SSA form, VA record, or representative email.
  • Do not assume the same acronym or phrase means the same thing in SSDI, SSI, VA disability, workers comp, and private disability insurance.

Where date last insured may appear

Look for date last insured in SSA notices, appeal forms, hearing exhibits, medical records, work history reports, payment records, overpayment notices, VA records, and representative correspondence. The surrounding document usually matters more than the word alone.

How to use this definition

  • Copy the exact sentence where the term appears.
  • Write the document title, date, agency, benefit program, and deadline next to the term.
  • Ask whether the term changes eligibility, payment, evidence, work reporting, appeal strategy, or representative review.
  • Verify official SSA or VA sources before filing, appealing, or responding to a notice.

Practical note for date last insured

A stronger consultation question is not just what date last insured means. A better question is how it affects the next disability step: filing, appealing, preparing evidence, reporting work, responding to an overpayment, or reviewing a hearing decision.

Review boundary for Date Last Insured

This page can help organize date last insured, but it cannot decide eligibility, disability onset, medical severity, payment amount, overpayment fault, VA rating effect, or appeal outcome. Those conclusions depend on the specific notices, medical evidence, work records, payment records, program rules, and deadlines.

Before sharing records

  • Make one working copy and keep originals in a controlled file.
  • Redact Social Security numbers, addresses, bank records, medical details, VA records, and payment information unless the recipient is clearly authorized.
  • Label each document with date, agency, benefit program, and status.
  • Write one narrow question for review instead of sending a large unsorted file.
