So, I am trying to get a better understanding of how the VA is supposed to determine analogous conditions when your condition is not listed. From reading 38 CFR 4.20, I believe they are supposed to find a disease that is analogous to my diagnosed disease as a whole, not just the symptoms I suffered. I have NMO and it can cause Transverse Myelitis or Optical Neuritis. For me, it caused TM. The VA assigned me code 8010 for Myelitis, however, my disease is often misdiagnosed as MS so I take that as being more analogous. MS shares more in common with NMO than TM. Actually, TM is a symptom of both of them. I'm trying to find others who may have run into a situation like this. I have also looked for other cases that include NMO code assignments. Any help would be greatly appreciated. I am going through IDES right now and I am about to as for a VARR (VA Reconsideration Request).
