Direct answer
Do SSDI denials expire?
SSDI denials do not 'expire,' but each denial notice starts a 60-day clock: if you do not appeal within 60 days of the date on the notice, the decision becomes administratively final and you generally must start over with a new application.
The SSA allows an additional five days for mailing and can extend the deadline for good cause when circumstances beyond your control prevented a timely appeal.

What is the 60-day appeal deadline?
You have 60 days from the date on the denial notice to file the next level of appeal — reconsideration, hearing, Appeals Council, or federal court.
What is 'good cause' for missing the deadline?
Reasons such as serious illness, misinformation from the SSA, records not received, or other circumstances beyond your control.
What if the deadline passes without good cause?
The decision becomes final at that level and you would need to file a new application, losing appeal rights and back pay tied to the earlier claim.
