Yes.Is it possible for the VA to make such a determination to increase/decrease solely on a C&P exam? That is all that is listed as evidence on the letter I received
However, when you get a PROPOSAL to reduce your VA award, the decision to reduce is not final.
You have 30 days from the date of the proposal to reduce to request a hearing,
You have 60 days to provide evidence as to why the reduction should not occur.
I will confirm later whether my remarks are accurate...it has been a few years.
