Thumb and long (DC 5143)

Body system: Musculoskeletal SystemRegulation: 38 CFR § 4.71a

Diagnostic Code 5143 appears to be an incomplete or outdated rating code that references 'Thumb and long' - likely referring to thumb and finger injuries together. This code is not currently used in the standard VA rating schedule for musculoskeletal conditions. Veterans with thumb and finger issues should look to the complete diagnostic codes in the 5220s series, which provide specific rating criteria based on range of motion loss, ankylosis (joint stiffness), and amputation levels.

Rating levels

  • 50% — If you've lost your thumb and long finger on your dominant hand, you receive a 50% rating. On the non-dominant hand the same amputation rates at 40%. VA treats the hand you write with as your "major" (dominant) hand; the other is your "minor" (non-dominant) hand, and ratings are 10% lower because loss of function on the non-dominant side is considered less disabling.
  • 40% — If you've lost your thumb and long finger on your non-dominant hand, you receive a 40% rating. On the dominant hand the same amputation rates at 50%. VA treats the hand you write with as your "major" (dominant) hand; the other is your "minor" (non-dominant) hand, and ratings are 10% lower because loss of function on the non-dominant side is considered less disabling.
