Amputation of thumb, index, long and little fingers

Medical records confirming the amputation of the thumb, index, long, and little fingers on the same hand are the foundation of a rating under this code. Surgical operative reports, pathology findings, or post-amputation treatment notes that identify which hand is affected — and whether it is your major or minor hand — are directly relevant, because the percentage differs between the two.

If ankylosis or severely limited motion of remaining finger structures is also present and may be evaluated as an amputation equivalent, examination findings matter. These include measurements of joint angles, the gap between fingertips or thumb pad and the palm crease when flexed, and notation of any rotation or angulation of bone. Statements from you or people who know you describing how the loss of these four digits affects grip, daily tasks, or work duties can help show the full functional impact, though the rating itself turns on which hand is involved and which fingers were lost.
