Secondary Condition Claim · VASRD 5243
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 Intervertebral Disc Syndrome (IVDS) when it develops after Ankylosis of the Lumbar Spine.
Fusion may compress spinal nerves.
Primary condition · VASRD 5234
Ankylosis of the Lumbar Spine
Ankylosis means abnormal stiffness or fusion of spinal joints, especially in the lumbar region.
Secondary condition · VASRD 5243
Intervertebral Disc Syndrome (IVDS)
Intervertebral disc syndrome involves damage to the cushioning discs between spinal vertebrae, which can bulge or herniate and press on nearby nerves, causing back pain, stiffness, and sometimes pain radiating into the arms or legs. Unlike most spine ratings based on range of motion, this code can alternatively be rated by counting incapacitating episodes requiring physician-prescribed bed rest.
The VA rates Intervertebral Disc Syndrome (IVDS) the same way whether it's claimed directly or as secondary to Ankylosis of the Lumbar Spine — severity of Intervertebral Disc Syndrome (IVDS) itself determines the percentage.
Example combined rating
50% Ankylosis of the Lumbar Spine + 20% Intervertebral Disc Syndrome (IVDS) = 60%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 50% and 20% combine to 60%, not 70%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
