I'm not sure the answer to your question. When I was granted SSDI, I didn't see anything in any paperwork scheduling me for a review down the line. Maybe I missed something. I'm similar to you in age, but a little bit older. Now that I am 63, I don't worry about it, since I would have the option of retiring at age 62, even without a disability.

Though I don't have a firm answer for you, I'll direct you to this passage that I've read:

"Although it is possible to lose benefits after a CDR, it is highly unlikely. In the most recent study published by the SSA, disability benefits after a CDR are continued over 95% of the time. Most individuals with impairments serious enough to be approved for disability in the first place do not medically improve, nor do they return to regular employment."

Combining that insight with your age, I would think it an even higher unlikelihood that you have any chance of having your benefit stopped.

But if you find a definitive answer, please share it. Maybe I'm taking too much for granted in my own case.
