The VA orders this exam to verify your diagnosis and measure how severe it is right now. It can shape your rating and your monthly compensation — but it does not decide your claim. A rating specialist weighs it against your full record, and if the exam does not reflect your condition, you can say so and ask the VA to correct it.

A condition where pain persists beyond normal healing time and becomes a condition in itself, affecting daily function. There is no diagnostic code for chronic pain syndrome. Under Saunders v. Wilkie (Fed. Cir. 2018) pain alone can be a disability for compensation purposes, but it still has to be rated by analogy under 38 CFR 4.20 to some listed condition — most often neuralgia or incomplete paralysis of the nerve whose distribution the pain follows. The levels below use the sciatic nerve scale (DC 8720/8520) as the worked example. Two limits shape the outcome: 38 CFR 4.124 caps a pure neuralgia at the evaluation for moderate incomplete paralysis, and 38 CFR 4.14 forbids rating the same pain twice under different diagnoses.
The percentages this diagnostic code can be rated at. Which one applies depends on the findings — no tool here can tell you in advance.
Rated under 38 CFR 4.124a, DC 8720/8520 (sciatic nerve) — rated by analogy under 38 CFR 4.20; ceilings at 38 CFR 4.123 and 4.124. The examiner records findings on the DBQ; a rating specialist makes the decision.
| Rating | Rating criteria | What that means for you |
|---|---|---|
| 0% | In every instance where the schedule does not provide a zero percent evaluation for a diagnostic code, a zero percent evaluation shall be assigned when the requirements for a compensable evaluation are not met. | Your chronic pain syndrome is service connected, but the record documents no dull, intermittent pain in a distribution that identifies a specific nerve, and examination finds no sensory or motor deficit, so there is no mild neuralgia to rate on the sciatic nerve scale this condition is rated by analogy to. This code prints no 0% rung of its own; § 4.31 supplies it: no monthly payment, but the condition is on record and a later increase runs from it. The lowest compensable level under this code is 10 percent. |
What supports this level
| ||
| 10% | Mild incomplete paralysis of the sciatic nerve: 10 percent. | You have mild chronic pain that is manageable with medication. The pain occasionally interferes with daily activities but does not prevent you from working. |
What supports this level
| ||
| 20% | Moderate incomplete paralysis of the sciatic nerve: 20 percent. Neuralgia, cranial or peripheral, characterized usually by a dull and intermittent pain, of typical distribution so as to identify the nerve, is to be rated on the same scale, with a maximum equal to moderate incomplete paralysis. | You have moderate chronic pain with characteristic episodes that affect your daily activities. The pain is present most days and requires ongoing treatment. |
What supports this level
| ||
| 40% | Moderately severe incomplete paralysis of the sciatic nerve: 40 percent. The maximum rating which may be assigned for neuritis not characterized by organic changes referred to in this section will be that for moderate, or with sciatic nerve involvement, for moderately severe, incomplete paralysis. | You have moderately severe chronic pain causing significant functional limitations. The pain is constant or near-constant and substantially limits your ability to work and perform daily tasks. |
What supports this level
| ||
| 60% | Severe incomplete paralysis of the sciatic nerve, with marked muscular atrophy: 60 percent. Neuritis, cranial or peripheral, characterized by loss of reflexes, muscle atrophy, sensory disturbances, and constant pain, at times excruciating, is to be rated on the scale provided for injury of the nerve involved, with a maximum equal to severe, incomplete, paralysis. | You have severe chronic pain with significant functional limitations. The pain dominates your daily life, severely limits your ability to work, and prevents many normal activities. |

The middle column is our transcription of the criteria at 38 CFR 4.124a, DC 8720/8520 (sciatic nerve) — rated by analogy under 38 CFR 4.20; ceilings at 38 CFR 4.123 and 4.124, condensed for reading. Read the section itself on eCFR before relying on the exact wording. The items under each level are the kinds of evidence that document it — not a VA checklist, and not a prediction of which level applies to you.
Not knowing what your pain is being rated as. "Chronic pain syndrome" is not in the rating schedule, so a decision always converts it into some listed condition by analogy, and which one it picks sets the ceiling. Rated as neuralgia, 38 CFR 4.124 caps you at the moderate level; rated as neuritis with documented organic changes — loss of reflexes, muscle atrophy, sensory disturbance — 38 CFR 4.123 lets you reach the severe level. Find the analogous code in your decision and work from it.
Being rated twice for the same pain. 38 CFR 4.14 forbids evaluating the same manifestation under different diagnoses. If the pain is already accounted for in a musculoskeletal rating, a second rating for the same pain will be denied — which is why identifying the single best-fitting code matters more here than filing more claims.
Chronic pain alone without an underlying diagnosed condition may be difficult to rate — ensure there is a medical diagnosis connecting the pain to a neurological or musculoskeletal cause.
Not documenting how pain limits daily activities, work capacity, and social functioning — the VA rates based on functional impact, so specific examples of limitations are essential.
Not keeping a pain diary showing frequency, intensity, and functional impact — a detailed log strengthens your claim by demonstrating the pattern and severity of your pain.
Consider whether the pain is better rated as part of an underlying condition (such as fibromyalgia, radiculopathy, or CRPS) rather than as a standalone diagnosis — the VA should rate under whichever code provides the most accurate and highest evaluation.
These apply to every C&P exam, whatever the condition.
