Why Median Nerve Paralysis Is Linked to Thumb, Limitation of Motion

Thumb, Limitation of Motion
DC 5228 rates a thumb that still moves but cannot reach the fingers. The whole evaluation is one measurement: the gap left between the thumb pad and the fingers when the veteran tries to touch them. More than two inches is 20 percent, one to two inches is 10 percent, and less than an inch is 0.

Median Nerve Paralysis VA Rating Tiers
The VA rates Median Nerve Paralysis the same way whether it's claimed directly or as secondary to Thumb, Limitation of Motion — severity of Median Nerve Paralysis itself determines the percentage.
Example combined rating
10% Thumb, Limitation of Motion + 30% Median Nerve Paralysis = 37%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 10% and 30% combine to 37%, not 40%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
