The anti-pyramiding rule is one of the most important concepts in VA disability ratings. It prevents VA from assigning separate ratings for the same symptoms or disability under different diagnostic codes. Each symptom can only be compensated once. For example, if you have a knee condition that causes both pain with movement and instability, VA can assign separate ratings for limited motion and instability because those are different symptoms. However, VA cannot assign two separate ratings for limited motion under two different diagnostic codes for the same knee. The pyramiding rule protects against double compensation but it should not be used to deny you ratings the evidence supports. The key question is whether the symptoms being rated under different codes actually overlap. If two conditions produce genuinely different symptoms that affect you in different ways, separate ratings are appropriate even if they involve the same body part. This distinction matters frequently with conditions like back disabilities that can produce both orthopedic symptoms rated under musculoskeletal codes and neurological symptoms rated under nerve codes. Both ratings are appropriate because they compensate different types of impairment. If VA denies a separate rating by citing pyramiding, examine whether the symptoms are truly the same or whether they represent distinct types of disability.
