Secondary Condition Claim · VASRD 5271
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 Ankle, Limitation of Motion when it develops after Common Peroneal Nerve Paralysis.
Weak foot control
Primary condition · VASRD 8528
Common Peroneal Nerve Paralysis
Paralysis or weakness in the lower leg affecting foot lift (foot drop).
Secondary condition · VASRD 5271
Ankle, Limitation of Motion
Reduced ability to flex or extend the ankle, usually due to injury or arthritis.
The VA rates Ankle, Limitation of Motion the same way whether it's claimed directly or as secondary to Common Peroneal Nerve Paralysis — severity of Ankle, Limitation of Motion itself determines the percentage.
Example combined rating
30% Common Peroneal Nerve Paralysis + 10% Ankle, Limitation of Motion = 37%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 30% and 10% combine to 37%, not 40%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
