[c.smith]

What's the maximum length of time anyone knows of a veteran receiving TDIU benefits?

 

[greg]

As long as they needed it or were eligible for it.

TDIU is indefinite, provided the veteran isn't engaged in substantial work. It doesn't expire after a certain period or when the veteran reaches a specific age.
