Gulf War Illness / Undiagnosed Illness — VA Disability Rating Guide
Diagnostic Code 6354 · 38 CFR §3.317
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.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | Symptoms are debilitating and constant, making you unable to work or perform basic self-care. |
| 60% | Symptoms are nearly constant and severely limiting with frequent incapacitating episodes. |
| 40% | Symptoms cause frequent debilitating episodes with substantial limitations in physical activity, concentration, and daily functioning. |
| 20% | Symptoms are moderate and affect daily routine noticeably. |
| 10% | Qualifying chronic symptoms are present but mild. You can generally work and function, though symptoms cause some reduction in energy, concentration, or physical comfort. |
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
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.
