What evidence decides the rating

For infectious diseases conditions, these are the findings VA weighs when assigning a percentage. If your examination did not address them, the examination may be inadequate for rating purposes — which is itself an argument on appeal.

  • Whether the disease is active or resolved, and what residuals remain
  • For chronic fatigue syndrome: debilitating fatigue that reduces daily activity to less than 50% of pre-illness level, and whether it is incapacitating

Why these claims get denied or under-rated

These are the failure patterns we see most often on avitaminosis and related infectious diseases claims:

  • Residuals were never separately rated after the active disease resolved
  • Undiagnosed illness and Gulf War presumptive pathways were not considered

If your claim was denied or under-rated

A denial is not the end of the claim. Which route is right depends on why VA decided the way it did:

  • Higher-Level Review — when the evidence already in the file supports a grant and VA got the decision wrong, or the examination was inadequate.
  • Supplemental Claim — when you have new and relevant evidence, such as a private nexus opinion.
  • Board Appeal — when you need a Veterans Law Judge to decide, or want a hearing.
  • Clear and Unmistakable Error — when a decision more than a year old contains an undebatable error, which can recover retroactive pay.

Effective dates matter as much as the percentage. See effective dates and back pay for how far back an award can reach.
