Was referred ot AO site with my questions. Am new to forum and VA system. I have several questions, so please be patient. Served in VN. Entered VA system 8/8/11,approved for benefits on 9/28/11; filed for compensation 11/8/11 (IHD, tinnitus, hearing loss, diabetes II, hypertension, bilateral neuropathy) Completed C&P 4/27/12. Claim is in decision approval status. Have hx of triple bypass surgery, aortic aneurysm, BKA left leg. Have also filed for SAH grant due to medical conditions. Went to VAMC see vascular, since BKA is not healing after 7 months and to discuss revision on BKA for prosthesis. Needed stress test, turned out positive. Waiting on cardiologist. Obtained copy of C&P reports prior to stress test and METS was 1-3. Have not had Echo yet, suppose to have it 6/9/12. Last Echo by private cardio in 2007 showed LVEF 25%. VSO is VA. My question is do I need to revise my claim in lieu of new developments or wait until I get a decision and appeal? I did not file for IU, do I need to do that? Ebenefits has added "View Required Evidence", what is that? I clicked and nothing tells me what I need to do, it just shows everything they have asked for and received. Do I need to do anything else? Any assistance will be greatly appreciated.
