Secondary Condition Claim · VASRD 5242
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 Degenerative Arthritis of the Spine when it develops after Muscle Group XV (Hip/Knee Flexors).
Altered walking posture
Primary condition · VASRD 5315
Muscle Group XV (Hip/Knee Flexors)
Injury or weakness in muscles that flex the hip and knee.
Secondary condition · VASRD 5242
Degenerative Arthritis of the Spine
Wear and tear in the spine causing stiffness, pain, or nerve issues.
The VA rates Degenerative Arthritis of the Spine the same way whether it's claimed directly or as secondary to Muscle Group XV (Hip/Knee Flexors) — severity of Degenerative Arthritis of the Spine itself determines the percentage.
Example combined rating
10% Muscle Group XV (Hip/Knee Flexors) + 20% Degenerative Arthritis of the Spine = 28%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 10% and 20% combine to 28%, not 30%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
