Gulf War Illness / Undiagnosed Illness — VA Disability Rating Guide
Diagnostic Code 6354 · 38 CFR §4.88b
What Is It?
Gulf War illness refers to a cluster of chronic, unexplained symptoms affecting veterans who served in Southwest Asia from 1990 onward. The VA has special provisions for these veterans — qualifying chronic symptoms that cannot be attributed to a known diagnosis may be granted presumptive service connection as an undiagnosed illness or medically unexplained chronic multi-symptom illness. 38 CFR 3.317 and the rating schedule answer two different questions. Section 3.317 is what allows an undiagnosed illness or a medically unexplained chronic multi-symptom illness to be service connected, and the only percentage it prints is the 10 percent threshold; the evaluation itself comes from the rating schedule in 38 CFR part 4. That means chronic fatigue syndrome under DC 6354, the criteria set out on this page; fibromyalgia under DC 5025; a functional gastrointestinal disorder under the code 38 CFR 4.114 provides for it; and an undiagnosed illness whose signs belong to another body system by analogy under 38 CFR 4.20 to the most closely related listed condition, carrying a built-up code number under 38 CFR 4.27.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | Debilitating fatigue, cognitive impairments (such as inability to concentrate, forgetfulness, or confusion), or a combination of other signs and symptoms which are nearly constant and so severe as to restrict routine daily activities almost completely and which may occasionally preclude self-care. |
| 60% | Debilitating fatigue, cognitive impairments (such as inability to concentrate, forgetfulness, or confusion), or a combination of other signs and symptoms which are nearly constant and restrict routine daily activities to less than 50 percent of the pre-illness level; or which wax and wane, resulting in periods of incapacitation of at least six weeks total duration per year. |
| 40% | Debilitating fatigue, cognitive impairments (such as inability to concentrate, forgetfulness, or confusion), or a combination of other signs and symptoms which are nearly constant and restrict routine daily activities from 50 to 75 percent of the pre-illness level; or which wax and wane, resulting in periods of incapacitation of at least four but less than six weeks total duration per year. |
| 20% | Debilitating fatigue, cognitive impairments (such as inability to concentrate, forgetfulness, or confusion), or a combination of other signs and symptoms which are nearly constant and restrict routine daily activities by less than 25 percent of the pre-illness level; or which wax and wane, resulting in periods of incapacitation of at least two but less than four weeks total duration per year. |
| 10% | Debilitating fatigue, cognitive impairments (such as inability to concentrate, forgetfulness, or confusion), or a combination of other signs and symptoms which wax and wane but result in periods of incapacitation of at least one but less than two weeks total duration per year; or symptoms controlled by continuous medication. |
Evidence Needed
Evidence of qualifying service in the Southwest Asia theater of operations. Symptoms must have manifested during or after service and persisted for at least six months. Medical records documenting chronic symptoms, even without a definitive diagnosis, are the primary evidence. The PACT Act removed the manifestation deadline and the 10 percent minimum from the statute; 38 CFR 3.317, the regulation VA adjudicators apply, still printed both when this page was last reviewed.
C&P Exam Tips
Describe every persistent symptom — fatigue, pain, headaches, digestive problems, cognitive difficulties, skin issues, respiratory complaints. The cluster of multiple unexplained symptoms is what characterizes Gulf War illness.
How to File
File on VA Form 21-526EZ. Reference your Southwest Asia service and describe all chronic symptoms. You do not need to provide a diagnosis for undiagnosed illness claims.
Common Mistakes
Counting bad weeks that no doctor prescribed rest for. The Note to DC 6354 says incapacitation exists only when a licensed physician prescribes bed rest and treatment, so the weeks that count toward the incapacitation periods in the rating criteria are the ones a treatment record shows a physician ordered, not every week the symptoms were bad. The biggest mistake is not filing because you do not have a specific diagnosis. Gulf War illness provisions exist precisely for veterans with unexplained chronic symptoms.
Frequently Asked Questions
Do I need a diagnosis to file for Gulf War illness?
No. The undiagnosed illness provision requires qualifying symptoms, not a specific diagnosis.
Which regions qualify as the Southwest Asia theater?
38 CFR 3.317(e) lists Iraq, Kuwait, Saudi Arabia, the neutral zone between Iraq and Saudi Arabia, Bahrain, Qatar, the United Arab Emirates, Oman, the Gulf of Aden, the Gulf of Oman, the Persian Gulf, the Arabian Sea, the Red Sea, and the airspace above these locations. The statute reaches further than the regulation as codified — 38 U.S.C. 1117(f) also names Afghanistan, Israel, Egypt, Turkey, Syria and Jordan — and the Gulf War Illness and Southwest Asia Presumptions guide sets out both.
What are the three presumptive diagnoses for Gulf War veterans?
Chronic fatigue syndrome, fibromyalgia, and functional gastrointestinal disorders are specifically recognized as medically unexplained chronic multi-symptom illnesses for Gulf War veterans.
