I did not use a VSO when I filed the claim for Temp. 100% disability and the VA paid for a doctor outside of VA to do the TKR. The increase for my left knee was denied due to thigh extension but I was given a 0% rating for scars. I called the VA, 800 number and the VA person told me that because I have a appeal for a increase on my left knee and a claim for Temp. 100% disability because of the TKR, VA will only process the appeal. The VA person told me if I withdraw my appeal and resubmit my claim for Temp. 100% disability they could process it. Thanks for any help you can give me.
