This legislation seeks to improve the Department of Veterans Affairs' system for rating disabilities by amending title 38, United States Code. A central provision mandates that the VA's disability rating schedule must be constructed to discount the beneficial effects of medication or treatment when a baseline without those effects can be established. This ensures that a veteran's disability rating reflects the severity of their condition prior to improvements gained from medical interventions. The bill also clarifies that this provision does not prevent veterans from seeking compensation for additional disabilities resulting from medication or treatment . It further ensures that claims for the aggravation of a preexisting service-connected injury or disease remain unaffected, aiming for a more accurate assessment of a veteran's disability for compensation.
