Chronic Fatigue Syndrome — VA Disability Rating Criteria (DC 6354)
Diagnostic Code 6354 · 38 CFR §4.88b
What Is It?
Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME/CFS), is a complex condition characterized by profound fatigue that is not improved by rest and is worsened by physical or mental exertion. Diagnosis requires the fatigue to persist for six months or more and to significantly reduce activity levels. CFS is particularly relevant for Gulf War veterans, as it is recognized as a qualifying medically unexplained chronic multi-symptom illness under 38 CFR 3.317.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | Symptoms that are nearly constant and so severe as to restrict routine daily activities almost completely and which may occasionally preclude self-care. |
| 60% | Symptoms that are nearly constant and restrict routine daily activities to less than 50 percent of the pre-illness level, or symptoms that wax and wane resulting in periods of incapacitation of at least six weeks total duration per year. |
| 40% | Symptoms that are nearly constant and restrict routine daily activities to 50 to 75 percent of the pre-illness level, or symptoms that wax and wane resulting in periods of incapacitation of at least four but less than six weeks total duration per year. |
| 20% | Symptoms that are nearly constant and restrict routine daily activities by less than 25 percent of the pre-illness level, or symptoms that wax and wane resulting in periods of incapacitation of at least two but less than four weeks total duration per year. |
| 10% | Symptoms that 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
CFS diagnosis requires new onset of debilitating fatigue severe enough to reduce daily activity to less than 50 percent of the pre-illness level for at least six months, plus exclusion of other conditions. You also need six or more qualifying symptoms. For Gulf War veterans, evidence of service in Southwest Asia plus the diagnosis may be sufficient under the presumptive framework.
C&P Exam Tips
Be prepared to describe your daily routine in detail. Quantify the restriction in percentage terms. Keep a fatigue diary for at least 2-3 months before the exam. The rating hinges on the percentage of activity restriction and duration of incapacitation periods.
How to File
For Gulf War veterans, file on VA Form 21-526EZ and cite CFS as a presumptive condition under 38 CFR 3.317. For non-Gulf War claims, file as direct or secondary. Submit medical records showing the diagnosis and documentation of functional limitations.
Common Mistakes
The most common mistake is not documenting functional limitations in percentage terms. Another mistake is not pursuing the Gulf War presumptive path when eligible. Veterans also fail to keep fatigue diaries that document periods of incapacitation.
Frequently Asked Questions
Is CFS a Gulf War presumptive condition?
Yes. CFS qualifies as a medically unexplained chronic multi-symptom illness under 38 CFR 3.317 for veterans who served in the Southwest Asia theater of operations.
How do I prove the activity restriction percentage?
Keep a detailed daily activity journal documenting what you do each day compared to what you did before CFS onset.
Can CFS be claimed secondary to another condition?
Yes. CFS can be claimed secondary to conditions that cause chronic sleep disruption, immune dysfunction, or prolonged physical stress.
