Tony & Larry, my best to both of you with your appeals. I have done a lot of research and found that most claims are initially denied. Even when credible evidence has been presented the first time around. It seems that if you can prove the perimeter then you can and should win on appeal. In both of your cases I truly believe that your claims should be granted. Also keep in mind that the disease itself will only qualify for compensation if it is approved as service connected (SC). And when being treated, after treatment the residual effects of the disease is what is compensated. For example, IHD if SC, is 100% while being treated. Say you have bypass surgery after rehab (approx. 6 months) you are considered cured and compensation is reduced or eliminated; unless there is residual damage or problems. This is the same with any cancers, once treatment is completely over, unless there is residual damage the compensation usually stops. That is why doctor Nexus letters are helpful also the VA may require additional tests or exams. My best wishes to you both and if I can be of assistance let me know. LouB.
