Most granted radiculopathy claims are not direct claims. They are secondary claims growing out of a spine condition the VA has already service connected, and they are the single most commonly missed evaluation in a back or neck file.
Under 38 CFR 3.310, a disability that is proximately due to, the result of, or aggravated by a service-connected disability is service connected in its own right and rated separately.
Why the separate rating exists
Note (1) to the General Rating Formula for Diseases and Injuries of the Spine in 38 CFR 4.71a instructs the VA to rate any associated objective neurologic abnormalities separately under an appropriate diagnostic code. The spine rating measures motion and incapacitating episodes; it does not compensate the nerve.
In practice that means a veteran already rated 20 percent for a lumbar spine condition may be entitled to an additional evaluation for each leg with documented radiculopathy. Our sciatica guide covers the lower extremity codes and the cervical radiculopathy guide covers the arms.
What the opinion has to establish
An opinion that says only that radiculopathy is related to the back condition will not carry the claim. The reasoning is what makes it persuasive, as our guide on what a nexus letter is explains.
- A current diagnosis of radiculopathy, or documented neurologic findings in a dermatomal pattern, in the specific extremity claimed
- The service-connected spine condition, identified by the rating decision that granted it
- A medical explanation of the mechanism - which level is involved, how the disc, spur, or stenosis at that level compresses or irritates the root, and how the symptom pattern matches
- Consideration of the alternative causes the VA will weigh, such as diabetes, age-related change, or a civilian injury
Where veterans start
Every case is different, and there is no obligation at any step. When veterans want to understand what their records actually support, these are the two most common starting points:
- Medical records review
A licensed physician reviews your records for a $250 flat fee and identifies which conditions the available evidence may support. The fee is refunded in full if nothing supportable is identified.
- Nexus letter
When the records support one, a licensed provider writes the medical opinion that addresses the link between your condition and your service or an already service-connected disability.
Aggravation counts too
Secondary service connection does not require that the spine condition caused the nerve problem from nothing. Aggravation is enough: where a service-connected condition makes a nonservice-connected condition permanently worse, the additional disability is compensable under 38 CFR 3.310(b).
That path matters for veterans with diabetic neuropathy whose spine condition adds a radicular component on top of it. The opinion has to describe the baseline and the increase, not simply assert that things got worse.
If your decision letter never mentioned the leg
Many veterans have a spine rating and documented leg symptoms in the same VA treatment records, and no nerve evaluation at all. That is usually because no one claimed it explicitly and the examiner did not record the neurologic findings.
A new claim for the neurologic abnormality, supported by the findings already in the record, is the ordinary route. Free accredited help with filing is available to every veteran through a Veterans Service Officer, and our guide on why VA claims get denied helps identify what a prior decision actually found missing.
Related conditions in the same file
Spine conditions rarely travel alone. Altered gait from leg weakness loads the knees and hips, and years of guarding the neck load the shoulder. Our hip series, knee series, and shoulder series cover those claims, and the TDIU series covers what happens when the combined picture keeps a veteran from working.
