Secondary Condition Claim · VASRD 5243
Intervertebral Disc Syndrome (IVDS) Secondary to Spondylolisthesis or Segmental Instability
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 Spondylolisthesis or Segmental Instability.
Why Intervertebral Disc Syndrome (IVDS) Is Linked to Spondylolisthesis or Segmental Instability
Shifting vertebrae often pinch spinal nerves.
Primary condition · VASRD 5239
Spondylolisthesis or Segmental Instability
Spondylolisthesis is when one vertebra slips forward over another, often causing back pain and nerve compression.
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.
Intervertebral Disc Syndrome (IVDS) VA Rating Tiers
The VA rates Intervertebral Disc Syndrome (IVDS) the same way whether it's claimed directly or as secondary to Spondylolisthesis or Segmental Instability — severity of Intervertebral Disc Syndrome (IVDS) itself determines the percentage.
| Rating | Criteria |
|---|---|
| 100% | The entire spine — neck and back together — is fused rigid in a poor position. This level is reached only through the range-of-motion formula, not through incapacitating episodes. |
| 60% | At least 6 weeks of physician-prescribed bed rest for disc flare-ups in the past 12 months. This level is reached only through incapacitating episodes, not through the range-of-motion formula. |
| 50% | The whole mid and lower back is fused rigid in a poor position, though the neck still moves. This level is reached only through the range-of-motion formula, not through incapacitating episodes. |
| 40% | Range-of-motion route: the whole neck is fused rigid in a poor position, the lower back bends forward only 30 degrees or less, or the whole mid and lower back is fused in a neutral position. Bed-rest route: at least 4 but less than 6 weeks of physician-prescribed bed rest in the past 12 months. Meeting either one is enough — VA applies whichever of the two methods pays more. |
| 30% | The neck bends forward only 15 degrees or less, or the whole neck is fused in a neutral position. This level is reached only through the range-of-motion formula, not through incapacitating episodes. |
| 20% | Range-of-motion route: moderate loss of back or neck motion, or muscle spasm or guarding bad enough to change how you walk or hold your spine. Bed-rest route: at least 2 but less than 4 weeks of physician-prescribed bed rest in the past 12 months. Meeting either one is enough — VA applies whichever of the two methods pays more. |
| 10% | Range-of-motion route: mild loss of back or neck motion; or muscle spasm, guarding, or localized tenderness that does not change gait or posture; or a vertebral body that lost half its height or more in a fracture. Bed-rest route: at least 1 but less than 2 weeks of physician-prescribed bed rest in the past 12 months. Meeting either one is enough — VA applies whichever of the two methods pays more. |
Example combined rating
30% Spondylolisthesis or Segmental Instability + 20% Intervertebral Disc Syndrome (IVDS) = 44%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 30% and 20% combine to 44%, not 50%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.

Evidence for a Intervertebral Disc Syndrome (IVDS) Secondary Claim

- •Notes from a spine surgeon or orthopedist documenting the diagnosis and treatment plan.
- •Physician orders for bed rest during flare-ups - this is the specific evidence the incapacitating-episode rating method requires.
Common questions about Intervertebral Disc Syndrome (IVDS) secondary to Spondylolisthesis or Segmental Instability
- Can Intervertebral Disc Syndrome (IVDS) be service-connected as secondary to Spondylolisthesis or Segmental Instability?
- Yes. Under 38 CFR § 3.310, a condition that is caused or aggravated by an already service-connected disability can be granted secondary service connection. Shifting vertebrae often pinch spinal nerves. You'll need a current Intervertebral Disc Syndrome (IVDS) diagnosis and a medical nexus opinion linking it to your se…
- What VA rating can I get for Intervertebral Disc Syndrome (IVDS) as a secondary condition?
- Intervertebral Disc Syndrome (IVDS) is rated under VASRD diagnostic code 5243 using the same criteria whether it's a direct or secondary claim: possible ratings are 100%, 60%, 50%, 40%, 30%, 20%, 10%. The rating depends on the severity of Intervertebral Disc Syndrome (IVDS) itself, not on the severity of Spondylolisth…
- How does a secondary Intervertebral Disc Syndrome (IVDS) claim affect my combined VA rating?
- The VA doesn't add ratings together. Using the official combined-ratings formula (38 CFR 4.25): a 30% rating for Spondylolisthesis or Segmental Instability combined with a 20% rating for Intervertebral Disc Syndrome (IVDS) (example figures) produces a combined rating of 44%, not 50%. Approving Intervertebral Disc Synd…
- What evidence do I need to service-connect Intervertebral Disc Syndrome (IVDS) as secondary to Spondylolisthesis or Segmental Instability?
- Strong evidence for the underlying Intervertebral Disc Syndrome (IVDS) diagnosis includes: MRI or CT imaging confirming disc damage or herniation.; Notes from a spine surgeon or orthopedist documenting the diagnosis and treatment plan.; Physician orders for bed rest during flare-ups - this is the specific evidence the…
