Radiculopathy and VA Disability: The Separate Rating Most Veterans Miss
Posted by Gregory M. Rada | June 28, 2026 | Disability Compensation
If you have a service-connected back or neck condition and you experience pain, numbness, tingling, or weakness that radiates into your arms or legs, you may be entitled to separate VA disability ratings for those symptoms. This condition is called radiculopathy (or sciatica, when it involves the sciatic nerve in the lower back and legs), and VA rates it under a completely different set of diagnostic codes than your spinal condition. That means it’s not included in your back or neck rating. It’s a separate, additional rating for each affected extremity. Many veterans have no idea this is available to them, and VA does not always identify or rate it on its own. The result is that thousands of veterans are living with nerve symptoms caused by their service-connected spinal conditions but receiving no compensation for them.

What Is Radiculopathy?
Radiculopathy occurs when a nerve root in the spine is compressed, irritated, or damaged. The compression is typically caused by the same kinds of spinal conditions veterans commonly develop: degenerative disc disease, herniated discs, spinal stenosis, or spondylolisthesis. When the nerve root is compressed, it sends pain, numbness, tingling, or weakness along the path of that nerve into the arms (for cervical radiculopathy, originating in the neck) or the legs (for lumbar radiculopathy, originating in the lower back).
The most common form of lumbar radiculopathy is sciatica, which involves compression of the sciatic nerve. Sciatica typically causes shooting pain from the lower back through the buttock and down the back of the leg, sometimes all the way to the foot. Many veterans describe it as a burning, electric, or stabbing sensation. It can also cause numbness, tingling, and in more severe cases, weakness in the affected leg or foot.
Cervical radiculopathy follows the same principle but affects the upper extremities. Compression of nerve roots in the neck can cause pain, numbness, and weakness radiating into the shoulders, arms, and hands. Veterans with service-connected cervical spine conditions who experience these symptoms may have ratable cervical radiculopathy that has never been claimed or evaluated.
Why It Gets a Separate Rating from Your Back or Neck Condition
This is the key point most veterans miss. VA rates spinal conditions (degenerative disc disease, herniated discs, lumbar strain, cervical strain) under the General Rating Formula for Diseases and Injuries of the Spine at 38 C.F.R. § 4.71a, Diagnostic Codes 5235 through 5243. Those ratings are based primarily on range of motion and functional limitation of the spine itself.
Radiculopathy, on the other hand, is a neurological condition. VA rates it under a completely different section of the rating schedule: 38 C.F.R. § 4.124a, Diseases of the Peripheral Nerves. The rating is based on the severity of nerve impairment, measured by motor loss, sensory disturbance, and muscle atrophy.
Because the spine rating and the radiculopathy rating address different types of impairment (musculoskeletal vs. neurological), they are not considered overlapping or “pyramiding” under 38 C.F.R. § 4.14. You are generally entitled to receive both: a rating for your spinal condition based on range of motion and functional limitation, and a separate rating (or ratings) for the neurological symptoms radiating into your extremities. Note 1 to the General Rating Formula for Diseases and Injuries of the Spine explicitly directs that any associated objective neurological abnormalities be evaluated separately under the appropriate diagnostic code.
In plain terms: your back rating covers the back itself. The radiculopathy rating covers the nerve damage that the back condition causes in your arms or legs. They’re separate disabilities under VA’s system, and you should generally be receiving separate compensation for each one.
How VA Rates Radiculopathy
The most common diagnostic code for sciatica and lumbar radiculopathy is DC 8520 (paralysis of the sciatic nerve). The ratings are based on the degree of incomplete or complete paralysis:
Mild incomplete paralysis is generally rated at 10%. This typically involves intermittent pain, tingling, or numbness that is mostly sensory in nature. Moderate incomplete paralysis is generally rated at 20%. Symptoms are more frequent and may include some motor involvement, such as mild weakness. Moderately severe incomplete paralysis is generally rated at 40%. This involves more significant motor loss, sensory deficits, and functional limitation. Severe incomplete paralysis with marked muscular atrophy is generally rated at 60%. Complete paralysis of the sciatic nerve, where the foot dangles and drops with no active movement below the knee, is rated at 80%.
For cervical radiculopathy affecting the upper extremities, VA uses different diagnostic codes depending on which nerve group is involved (DC 8510 for the upper radicular group, DC 8511 for the middle radicular group, DC 8512 for the lower radicular group, among others). The ratings depend on severity and also on whether the affected arm is the veteran’s dominant (“major”) or non-dominant (“minor”) side. Upper extremity nerve ratings are generally slightly higher than lower extremity ratings at comparable severity levels.
Most veterans with radiculopathy receive ratings in the 10% to 20% range. Higher ratings (40% and above) typically require objective evidence of motor involvement, such as muscle weakness, reduced reflexes, or atrophy, which may be documented through nerve conduction studies (NCS) or electromyography (EMG).
Each Extremity Is Rated Separately (and the Bilateral Factor Helps)
This is where the math can work strongly in a veteran’s favor. Each affected extremity receives its own rating. If you have lumbar radiculopathy affecting both legs, you receive one rating for the right leg and a separate rating for the left leg. If you have cervical radiculopathy affecting both arms, you receive one rating for each arm.
When both sides are affected, the bilateral factor under 38 C.F.R. § 4.26 also applies. VA combines the bilateral ratings and adds 10% of the combined value before factoring them into the rest of your combined rating. This provides a small but meaningful boost to the overall combined percentage.
Consider a veteran with a 40% rating for a lumbar spine condition. They also have bilateral sciatica, rated at 20% for each leg. Those two 20% leg ratings combine to 36% under VA math. The bilateral factor adds 10% of that value (3.6%), producing 39.6% (rounded to 40% for combining purposes). When that 40% bilateral radiculopathy value is combined with the 40% spine rating, the veteran’s combined spinal and neurological rating is approximately 64%, which rounds to 60%. Without the radiculopathy ratings, the veteran would be at 40%. That’s a significant increase in monthly compensation, and it may bring the veteran closer to (or over) the TDIU schedular thresholds.
Claiming Radiculopathy Secondary to Your Spinal Condition
Radiculopathy is one of the most straightforward secondary service connection claims available. The medical connection between spinal conditions and nerve root compression is well established and generally does not require extensive explanation. If you have a service-connected back or neck condition, and medical evidence shows that condition is causing nerve compression that produces symptoms in your extremities, the nexus is typically clear.
To claim radiculopathy secondary to a spinal condition, you would generally file a claim for VA disability compensation identifying radiculopathy as a new condition secondary to your existing service-connected spine disability under 38 C.F.R. § 3.310. If the radiculopathy affects both legs or both arms, claim each extremity separately.
The evidence that generally supports a radiculopathy claim includes treatment records documenting complaints of radiating pain, numbness, or tingling. C&P exam findings or treatment notes showing abnormal neurological signs such as reduced reflexes, decreased sensation, or weakness on examination. Imaging (MRI or CT) showing disc herniation, stenosis, or other structural findings that explain nerve root compression. And in cases where a higher rating is being sought, nerve conduction studies or EMG results that provide objective documentation of the type and severity of nerve involvement.
A nexus letter may be helpful in some cases, particularly if VA has not previously acknowledged the connection between the spinal condition and the nerve symptoms. But for many veterans, the medical records themselves may provide sufficient evidence of the relationship, especially if imaging shows disc pathology compressing a nerve root and the symptoms follow the expected distribution pattern for that nerve.
How Radiculopathy Affects Your Combined Rating and TDIU Eligibility
Adding radiculopathy ratings can substantially increase a veteran’s combined disability rating. Because each affected extremity is rated separately, a veteran with bilateral radiculopathy may add two or even four new ratings to their combined calculation. The bilateral factor provides an additional boost.
This matters for two reasons beyond the immediate increase in monthly compensation. First, higher combined ratings qualify veterans for additional benefits, including SMC-S (housebound) if the combined rating reaches the “100 plus 60” threshold. Second, radiculopathy ratings can push a veteran into TDIU eligibility territory. A veteran at 60% combined who adds bilateral radiculopathy ratings may cross the 70% combined threshold needed for schedular TDIU under 38 C.F.R. § 4.16(a).
Radiculopathy also strengthens the functional impairment picture for TDIU. Nerve pain that radiates down both legs makes it difficult to sit, stand, or walk for extended periods. Combined with the limitations from the underlying spinal condition (and potentially a mental health condition like depression secondary to chronic pain), radiculopathy can be a significant factor in establishing that the veteran cannot maintain substantially gainful employment.
What to Do If VA Hasn’t Rated Your Radiculopathy
If you have a service-connected back or neck condition and you experience any of the following symptoms, you may have ratable radiculopathy that VA has never addressed: shooting or burning pain radiating from the spine into an arm or leg, numbness or tingling in the hands, feet, or along a limb, weakness in a hand, arm, leg, or foot, difficulty gripping objects or tripping due to foot drop, or worsening nerve symptoms that correspond to flare-ups of your spinal condition.
Review your current rating decision. Look at whether VA rated any neurological conditions associated with your spine. If not, you may have unrated radiculopathy that entitles you to additional compensation. VA’s own rating criteria direct that associated neurological abnormalities be rated separately, but VA does not always follow through on this without a specific claim from the veteran.
If you’ve never been evaluated for radiculopathy, the first step is generally to get a diagnosis documented in your medical records. Talk to your treating provider about your nerve symptoms. If you already have treatment records documenting radiculopathy or nerve-related complaints, you may have enough evidence to file a secondary claim now.
At After Service, we review the complete claims file for every veteran we represent, looking for conditions that should be rated separately but aren’t. Unrated radiculopathy secondary to a spinal condition is one of the most common findings, and adding those ratings can significantly increase a veteran’s combined percentage, monthly compensation, and eligibility for benefits like TDIU.
