Chronic Fatigue Syndrome (CFS) VA disability rating & claim guide

Yes. The VA rates Chronic Fatigue Syndrome (CFS) under VASRD diagnostic code 6354 (Infectious Diseases and Immune Disorders). CFS causes persistent fatigue not improved by rest and worsened by physical or mental activity.

Possible VA ratings for Chronic Fatigue Syndrome (CFS) are 100%, 60%, 40%, 20%, 10%, 0%. The 0% level comes from 38 CFR 4.31, which assigns it wherever no compensable level is met. Examples: 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.

Vetrify estimates the typical rating awarded for Chronic Fatigue Syndrome (CFS) at around 40%, based on VA claims data and the rating schedule. Per the VBA Annual Benefits Report (FY2025), veterans receiving VA compensation as of September 30, 2025 had 38,073 service-connected disabilities rated as Chronic Fatigue Syndrome (CFS). The report counts disabilities, not veterans. Estimated approval outlook: Moderate – requires robust documentation and exclusion of other diagnoses.

Strong evidence for a Chronic Fatigue Syndrome (CFS) claim includes: VA physician diagnosis of CFS; Labs ruling out other causes; Personal logs of fatigue patterns; C&P exam documenting activity limits.

VA's Chronic Fatigue Syndrome Disability Benefits Questionnaire (DBQ) is on its public list of DBQs. VA's page says: "You can use these forms to submit medical evidence from your health care providers."

Common pitfalls when filing for Chronic Fatigue Syndrome (CFS): Missing proof of how the symptoms restrict daily activities, or of each period of physician-prescribed bed rest; No documented medical history of fatigue; Filed without ruling out other diagnoses.

Yes, for a veteran who meets a presumption's conditions. 38 CFR 3.317(a)(2) names "Chronic fatigue syndrome" among the medically unexplained chronic multisymptom illnesses of a Persian Gulf veteran, if it is chronic as 38 CFR 3.317(a)(4) defines it (6 months or more, or intermittent episodes of improvement and worsening over 6 months). The regulation still requires it to have appeared during service in the Southwest Asia theater or, to a degree of 10 percent or more, by December 31, 2026, and still counts only the Southwest Asia theater as Gulf War service (38 CFR 3.317(e)(1)); its statute, 38 U.S.C. 1117, drops the date and the 10 percent floor and adds Afghanistan, Israel, Egypt, Turkey, Syria and Jordan. 38 U.S.C. 1117(a)(2) names "chronic fatigue syndrome" among the medically unexplained chronic multisymptom illnesses for which a Persian Gulf veteran, as 38 U.S.C. 1117(f) defines one, may be paid compensation whenever it became manifest, to any degree (38 U.S.C. 1117(a)(1)). Each presumption gives way to affirmative evidence to the contrary (38 CFR 3.317(a)(7); 38 U.S.C. 1113).

Conditions that can be service-connected as secondary to Chronic Fatigue Syndrome (CFS), when a medical opinion links them, include: Depression; Fibromyalgia. A secondary condition gets its own rating, which VA combines with the veteran's other ratings under 38 CFR 4.25.
