Secondary Condition Claim · VASRD 8515
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Median Nerve Paralysis when it develops after Ankylosis of the Wrist (Unfavorable, extremely unfavorable).
Abnormal wrist angles compress the median nerve
Primary condition · VASRD 5223
Ankylosis of the Wrist (Unfavorable, extremely unfavorable)
A condition where the wrist is stuck in a harmful position and cannot move.
Secondary condition · VASRD 8515
Median Nerve Paralysis
Damage to the median nerve causing weakness, pain, or paralysis in the hand.
The VA rates Median Nerve Paralysis the same way whether it's claimed directly or as secondary to Ankylosis of the Wrist (Unfavorable, extremely unfavorable) — severity of Median Nerve Paralysis itself determines the percentage.
Example combined rating
40% Ankylosis of the Wrist (Unfavorable, extremely unfavorable) + 30% Median Nerve Paralysis = 58%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 40% and 30% combine to 58%, not 70%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
