I was awarded SSDI in AUG 2010 - retro to DEC 2007.
I went to my C&P exams for IDES in SEP/OCT 2010.
In other words, based on the medical evidence I already had BEFORE I even went to C&P exams, I had enough qualifying evidence to be awarded SSDI even before my C&P exams for the IDES process.
I did give the VA Rep in the IDES process a copy of my SSDI award letter (23 pages) so he could bundle it into the VA portion of the IDES process.
Gave a copy of it to the PEBLO, too, for the DoD side.
Took about a year before I got my 199 back - last C&P in OCT 2010 - 199 back in NOV 2011.
Seattle VA Regional handled my IDES claim.
I was finally awarded 70% DoD and 100% P&T in 2012 and retired onto PDRL.
V/R,
