The Department of Veterans Affairs (VA) employs a complex rating system to determine disability compensation. When a veteran experiences disability in both arms, both legs, or paired skeletal muscles, this is referred to as a bilateral disability. The VA acknowledges the impact of such conditions through a specific calculation that may increase the overall disability rating, and consequently, the compensation amount. This reflects the understanding that impairment in both limbs, for instance, creates a greater functional limitation than impairment in a single limb.
The consideration of disabilities affecting paired body parts is crucial because it recognizes the synergistic effect of bilateral impairments. Historically, the VA system evolved to account for the amplified impact of disabilities in corresponding limbs or organs. This acknowledgment serves to provide more appropriate and equitable compensation, addressing the compounded challenges veterans face in their daily lives due to these combined limitations. The bilateral factor is intended to reflect the greater loss of function and quality of life.
