Numbness down the arm, a hand that goes to sleep, weakness gripping a coffee cup, or a burning line from the shoulder to the thumb are nerve symptoms, not joint symptoms, and the VA rates them under a completely different part of the schedule.
The nerve codes
38 CFR 4.124a covers the peripheral nerves. For the arm, the relevant groups are:
- DC 8510 - upper radicular group, the C5 and C6 nerves, affecting the shoulder and upper arm
- DC 8511 - middle radicular group
- DC 8512 - lower radicular group, affecting the forearm and hand
- DC 8513 - all radicular groups, where the whole plexus is involved
- DC 8515 - median nerve, the code used for carpal tunnel syndrome
- DC 8516 - ulnar nerve
Each code has three parallel series. The 85xx codes rate paralysis, the 86xx codes rate neuritis, and the 87xx codes rate neuralgia. Brachial neuritis of the upper radicular group, for example, is rated under DC 8610 using the criteria of DC 8510.
Within each code, percentages run from mild incomplete paralysis up through moderate, severe, and complete, and the major arm is rated higher than the minor arm at most levels under 38 CFR 4.69.
The wholly sensory rule
This single provision decides a large share of nerve ratings. 38 CFR 4.124a states that when the involvement is wholly sensory, the rating should be for the mild, or at most the moderate, degree. Numbness and tingling alone, however constant and unpleasant, generally cap out at the moderate level.
What moves a rating higher is objective motor involvement: measured strength deficits, documented muscle atrophy, diminished reflexes, and electrodiagnostic findings such as an EMG or nerve conduction study showing more than sensory change. If those findings exist in your records, they need to be in the file the rater reads.
Where the symptoms come from matters
Arm nerve symptoms have several possible sources, and the VA treats them differently. A traction injury to the brachial plexus from a fall or a heavy pack is rated on the plexus codes. Symptoms originating from a cervical disc compressing a nerve root are usually rated as radiculopathy associated with the neck condition, which our cervical radiculopathy guide covers in detail. Entrapment at the wrist is carpal tunnel under DC 8515.
An examiner or an independent reviewer should identify the likely source, because the diagnosis determines the code and the code determines the percentage. Where more than one source contributes, the opinion should say so and explain the reasoning.
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.
Combining with the shoulder rating
A veteran can hold a shoulder rating for limitation of motion and a separate nerve rating for the same arm, because pain and restricted motion are distinct from sensory and motor loss. That is not pyramiding under 38 CFR 4.14, which prohibits rating the same manifestation twice, not rating two different manifestations.
The percentages are combined under 38 CFR 4.25 rather than added, and when both upper extremities are service connected the bilateral factor applies. Our combined rating calculator handles both steps. Our shoulder rating guide covers the orthopedic side.
Evidence for a nerve claim
The strongest nerve claims include an electrodiagnostic study where one has been done, a neurological examination documenting sensory distribution and strength by muscle group, imaging identifying a structural cause, and a record showing how long the symptoms have persisted. Lay evidence matters too: dropping objects, burning that wakes you at night, and difficulty with buttons or tools are functional facts the record should reflect.
Long thoracic and axillary nerve injuries
Beyond the radicular groups and the median and ulnar nerves, two specific nerves matter for shoulder function. Injury to the long thoracic nerve, rated under DC 8519, produces a winged scapula because the serratus anterior muscle no longer holds the shoulder blade against the chest wall, which is often visible on examination when the veteran pushes against a wall. Injury to the axillary nerve, rated under DC 8518, weakens the deltoid and can follow a shoulder dislocation or a fracture near the joint.
Both are peripheral nerve injuries rated under the same paralysis, neuritis, and neuralgia framework as the radicular groups, with percentages depending on whether the impairment is mild, moderate, or severe, and whether motor loss is present in addition to sensory change.
Electrodiagnostic testing and what it adds
An electromyography study, commonly called an EMG, and a nerve conduction study are the objective tests that distinguish sensory-only nerve irritation from nerve damage involving motor fibers. These studies can identify which nerve or nerve root is affected, how severe the damage is, and whether the problem is acute or chronic.
Because 38 CFR 4.124a caps wholly sensory involvement at the mild or moderate level, a normal sensory examination paired with an EMG showing denervation in a specific muscle can be the difference between a moderate and a severe rating. When these studies have been performed, the report itself, not just a treatment note referencing it, should be part of the claim file.
Where no electrodiagnostic testing has been done and the clinical picture is ambiguous, a treating provider or an independent reviewer can note that testing would clarify the picture, which is useful information for the veteran to bring to a future appointment even though the VA cannot compel a specific test to be performed.
Distinguishing brachial neuritis from thoracic outlet syndrome
Thoracic outlet syndrome involves compression of the brachial plexus, the subclavian artery, or the subclavian vein as they pass between the collarbone and the first rib, and it can produce symptoms that overlap heavily with brachial neuritis, including arm pain, numbness, and weakness that worsens with overhead activity. The two are not the same diagnosis, and distinguishing them can matter for treatment as well as for which code most accurately describes the impairment.
A vascular examination, positional testing, and sometimes imaging of the thoracic outlet help make that distinction. Because thoracic outlet syndrome is still fundamentally a plexus compression, it is generally rated under the same DC 8510 series once diagnosed, but a clear diagnosis prevents confusion at the rating stage about which condition the medical evidence actually supports.
Frequently asked questions
What is the VA rating for brachial neuritis?
Brachial plexus conditions are rated under 38 CFR 4.124a, most often the upper radicular group at Diagnostic Code 8510, with neuritis rated under the parallel 8610 series and neuralgia under 8710. Percentages depend on whether the impairment is mild, moderate, severe, or complete, and on whether the affected arm is dominant.
Does numbness in my arm get rated separately from my shoulder?
Yes, when the symptoms are distinct. Orthopedic impairment is rated under the shoulder codes in 38 CFR 4.71a and nerve impairment under 38 CFR 4.124a. Rating both is permitted because the symptomatology differs, but the VA will not rate the same functional loss twice.
What does wholly sensory mean?
When the nerve impairment involves only sensory symptoms such as numbness or tingling, with no motor weakness or atrophy, 38 CFR 4.124a directs that the rating be for the mild, or at most the moderate, degree. Motor findings such as measurable weakness or muscle wasting are what support higher levels.
