Thanks Dot09. When I was finally able to prove I had a head injury in service(they claimed no record of injury after never requesting the records, thus the CUE) and deficits due to the injury, my claim was approved but rater withheld funds being paid until competency is determined. There was no question of competency by anyone, health care professional or otherwise up to that point. He ordered a C&P exam. We know how those go and this was no different.
So, it turns out that my pcp has been through the process of getting a case like mine reversed successfully. With his prior vet, he said the only evidence that would sway reviewers was neuropsychological testing. So, that's what he ordered, neuropsychological testing to determine competency for VA purposes.
He's right of course. Neuropsych testing proved my TBI claim. Of course, I'm aware it may also prove that I am in fact, not competent. I'm pretty confident though. Will just have to wait for testing and results. This is moving along much faster than I thought it would.
