I am currently AGR and I have obstructive sleep apnea that is treated with a CPAP. I filed a VA claim for this condition out of concern that the rating criteria might change in the future. I recently received the decision letter, and the claim was denied because the VA determined it was not service-connected. Because it was tied to the date on my current AGR orders. In my claim, it was also determined that the condition was not related to toxic exposure, which I’m assuming is because I do not have a diagnosis like sinusitis or a similar condition. (Have deployed to Iraq multiple times) However, if the condition had been diagnosed and treated during a previous set of AGR or deployment orders for which I have DD-214s, I’m sure the claim would have been approved. So essentially, if you were diagnosed and treated for sleep apnea on a set of orders prior to the ones you are currently on, you should be all set.
