Going into detail about SSDI termination causes, it’s clear to see how SSDI can end and it is vital for anyone who is currently collecting SSDI benefits and depending on them to be aware of these situations:

Reaching full retirement age: It is not possible to collect SSDI benefits and Social Security retirement benefits simultaneously.  Upon reaching full retirement age, the SSA will automatically stop distributing SSDI benefits and start making traditional Social Security payments. For the most part, SSDI disbursements are the same as full retirement benefits, so recipients generally won’t see a change in payments or at least anything significant.

Incarceration: Collecting SSDI benefits? Follow the law or risk losing them.  The SSA will suspend SSDI and SSI payments
if a recipient is incarcerated for more than 30 days. The good news is for those that are incarcerated for more than 30 days, SSI payments can begin the month after release but not for
recipients who are confined for more than 12 months.  At this point, benefits are terminated and the
recipient must reapply in order to start receiving SSDI benefits again. Also, recent parolees don’t qualify for disability benefits.
