When a disc bulge, bone spur, or narrowed opening presses on a nerve root in the neck, the symptoms do not stay in the neck. They travel: burning across the shoulder blade, tingling down the outside of the arm, numb fingers, a hand that drops things, weakness that shows up when reaching overhead.
For rating purposes, that is a separate disability from the neck itself, and it is one of the most commonly overlooked parts of a cervical spine claim.
Why it is rated separately
Note 1 to the General Rating Formula in 38 CFR 4.71a instructs the VA to evaluate any associated objective neurologic abnormalities separately under an appropriate diagnostic code. The neck rating compensates lost motion. The radiculopathy rating compensates lost nerve function. They are different impairments, and both can be paid.
The separate ratings combine under 38 CFR 4.25 rather than adding, which our combined rating calculator applies.
How severity is graded
Peripheral nerve ratings in 38 CFR 4.124a are graded by the degree of incomplete paralysis - mild, moderate, or severe - with higher evaluations for complete paralysis and for the dominant extremity.
- Diagnostic Code 8510 - upper radicular group (fifth and sixth cervical nerves)
- Diagnostic Code 8511 - middle radicular group
- Diagnostic Code 8512 - lower radicular group
- Diagnostic Code 8513 - all radicular groups
- Diagnostic Codes 8515 and 8516 - median and ulnar nerves, where a specific nerve is involved
The regulation also provides that when the nerve involvement is wholly sensory, the rating should be for the mild degree, or at most the moderate degree. Objective findings - documented weakness, diminished reflexes, atrophy, or abnormal electrodiagnostic testing - are what move a rating past that ceiling.
The evidence that supports it
Radiculopathy claims turn on objective documentation, not just the description of symptoms.
- Imaging identifying the level and the nerve root involved
- Electromyography or nerve conduction studies where they have been performed
- Examination findings: sensory testing, reflexes, grip and muscle strength, atrophy measurements
- A treatment history showing the symptoms are persistent rather than occasional
- Your own account of which fingers go numb, when, and what tasks it interferes with
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.
Radiculopathy as a secondary claim
Where the cervical spine is already service connected, radiculopathy flowing from it is service connected under 38 CFR 3.310 as a secondary condition. The opinion supporting it addresses the anatomic pathway: which level is involved, which root it affects, and why the distribution of symptoms matches.
Our neck secondary conditions guide covers the broader set, and the lumbar radiculopathy and sciatica guide covers the same structure in the lower body.
Distinguishing radiculopathy from peripheral neuropathy
Radiculopathy and peripheral neuropathy both cause numbness and weakness in an arm, but they arise differently and the distinction affects which diagnostic code applies. Radiculopathy comes from a nerve root being compressed or irritated where it exits the cervical spine, so the pattern of symptoms follows the specific root involved, for example numbness along the thumb side of the hand with a C6 root problem.
Peripheral neuropathy, by contrast, arises from a problem with the nerve further along its path, such as at the elbow or wrist, and is not connected to the cervical spine at all. An examiner's electrodiagnostic testing, when performed, usually distinguishes the two by showing whether the abnormal finding localizes to the nerve root or to a more distal point along the nerve. Getting this distinction right in the medical opinion matters because a neuropathy unrelated to the neck would not be secondary to a cervical spine disability.
Bilateral radiculopathy
Cervical disc disease and stenosis can compress nerve roots on both sides of the spine at once, producing symptoms in both arms. Where that is documented, each arm is rated separately using the applicable diagnostic code in 38 CFR 4.124a, and 38 CFR 4.26 provides a small additional bilateral factor when the combined ratings for the two arms are calculated, recognizing the added impairment of losing function in both upper extremities rather than one.
Because the two sides can differ in severity, the exam should test and record findings independently for the left and right arm rather than treating the symptoms as a single combined impairment.
How electrodiagnostic testing is used
Electromyography and nerve conduction studies are not required for a radiculopathy claim, but where they have been performed they carry significant weight because they are objective rather than dependent on the veteran's description of symptoms. A normal study does not automatically defeat a claim, since early or intermittent nerve root irritation can produce a clinical picture without any electrodiagnostic abnormality, particularly if the test was done between flare-ups.
When the studies are abnormal, they typically specify which nerve root or roots are affected and the severity of the finding, which helps align the rating with the correct diagnostic code and severity level under 38 CFR 4.124a.
Frequently asked questions
Is cervical radiculopathy rated separately from the neck?
Yes. Note 1 to the General Rating Formula directs the VA to evaluate associated objective neurologic abnormalities separately under an appropriate diagnostic code. A veteran can hold a cervical spine rating plus separate ratings for each affected arm.
What diagnostic codes cover arm radiculopathy?
The radicular groups are rated under 38 CFR 4.124a: Diagnostic Code 8510 for the upper radicular group, 8511 for the middle, 8512 for the lower, and 8513 for all radicular groups. Individual nerves such as the median nerve at 8515 and ulnar nerve at 8516 have their own codes.
Does the dominant arm get a higher rating?
Yes. The rating schedule assigns higher evaluations for the major, or dominant, extremity than for the minor extremity at most severity levels.
What is incomplete paralysis?
Incomplete paralysis describes nerve impairment short of complete loss of function, graded mild, moderate, or severe. The regulation directs that when the involvement is wholly sensory, the rating should be for the mild, or at most the moderate, degree.
