Hello, I hope someone here can help me. My claim for hearing lost was denied a few months ago. Ebenefits showed "Not Service Connected" just like the other claims that were denied. I am SC for PTSD and have ED due to the medication I am taking. So, I filed ED as secondary to PTSD and had the C&P exam a few weeks ago. Today, I log into eBenefits and I see that the previously denied (closed) claim of hearing lost how shows in the Rating column "0%" but then next to it "Not Service Connected". The "0" wasn't there before. The claim for ED as secondary to PTSD shows "Not Service Connected". My questions are: 1) Is it normal to have a rating and no Service connection? Why assign a rating if not Service Connected? 3) Have you ever had a claim that is closed as denied and then weeks/months later the rating changes without you putting an appeal? 3) Could it be that they made a mistake and actually meant to assign the 0% to ED? Any help to try to understand is greatly appreciated. Thank you.
