Amputation of the thumb and middle finger on one hand.
The central fact VA needs to confirm is that you have experienced anatomical loss of both the thumb and the long finger. Surgical operative reports, amputation records, and pathology reports document the fact and level of loss. A VA or private examination that physically confirms the absence of these digits on the named hand is also key evidence.
Records identifying which hand is your major (dominant) or minor (nondominant) hand support the correct percentage. A statement from you or someone who knows you well — describing how the loss of these two digits affects tasks at work or in daily life, such as gripping, writing, or handling objects — can help VA understand the full picture of your disability. Any records showing whether additional digits on the same hand are also affected may be relevant if VA is evaluating multiple losses together.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
