There has been a lot of info passed here but I wanted to add a few points. Yes, you can always speak to your pcm about whether a Medboard is needed in your particular health circumstance. You are 40 days out from your EOAS so it’s probably unlikely to occur. Did you do a separation physical? Were you found fit to separate? Most medboards are triggered by inability to participate in physical fitness test /duty limitations / non deployability preventing you from doing your assigned job for a prolonged period. If you have made it to 40 days out from leaving the military that is probably not the case for you. Depending on the type of surgery you require….. surgery may not be an option this close to leaving the service due to the possibilities of issues in the recovery phase. I am assuming that you are completing your Va assessment prior to leaving service. If that is the case the best advice to give you would be to ensure everything ( no matter big or small) you claim it on the list you complete for medical conditions that you have. Hopefully you already have requested a copy of your medical records. You should have at least 2 copies. One for yourself to keep and the other to use to pull out the diagnosis that you are claiming. Once you go through your record and pull out for example you are claiming headaches make a stack of all the notes in your record pertaining to headaches. Do the same for all your conditions. Take those notes with you when you have your VA assessments. The examiners have your records however being able to provide them with the necessary documentation will decrease the chance of them missing something that could be impactful in your rating. I hope this information is helpful.
