Amputation of the index, middle, and little fingers on one hand.
Medical records documenting the anatomical loss of the index, long, and little fingers are the core evidence for a rating under this code. Surgical or operative reports, discharge summaries, and pathology findings can confirm the nature and extent of the loss. A VA or private medical examination that identifies which hand is your dominant hand and which is your nondominant hand directly affects whether the 50% or 40% level applies, so records or statements establishing handedness matter.
If the condition involves ankylosis or limited motion rather than outright amputation, examination findings should measure the range of motion at each affected joint and record the gap between your fingertips and the proximal transverse crease of your palm when you try to flex your fingers. Findings showing whether joints are fixed in favorable or unfavorable positions are also relevant. Statements from you or people who know you describing how the loss of these three fingers affects tasks at work and in daily life can help show the full picture of your disability.
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.
