I need help. I first applied for benefits in 2016 and was denied in 2017 because the VA could not find my medical records. I was able to locate my medical records and I did a NOD. I filed again for the conditions and sent in my medical records. Fast forward to 2019. I was able to get C&P Exams at the end of 2019 and Jan 2020. My Sleep Apnea exam took about 3 minutes or so...questions were: When did you enter AD? When did you retire? Do you have a CPAP? I had submitted a buddy letter from the EX and my medical records showed weight gain, snoring, ENT problems, etc.I answered the questions and affirmed that I had a CPAP. That was all of the questions I had for Sleep Apnea. I had a few other exams and even a hearing exam. I was asked about my MOS/AFSC and told them the first five years was flight line work at a SAC base. I told them of the ringing in my ears and thought I'd be rate for tinnitus. My hearing exam showed I did not have much hearing loss. Fast forward again. I was asked to submit to additional exams for my feet and hands in Nov 2020. In any manner, I was finally rated at 20% for my feet and zero for my broken fingers. Since I had to file a NOD I elected higher level review by a DRO. My question is can I file a rebuttal for the other items filed? I need this ASP since I just received notice on 1 April 2021. Thank you.
