The VA rates chronic fatigue syndrome under Diagnostic Code 6354 in 38 CFR § 4.88b, assigning 10%, 20%, 40%, 60%, or 100% based on how severely the illness restricts your daily activities and how many weeks per year it leaves you incapacitated. Before any rating is possible, a physician must diagnose CFS under the specific criteria in 38 CFR § 4.88a. Gulf War veterans can reach a rating through a presumptive service connection, but the presumption requires the illness to have manifested at a compensable level no later than December 31, 2026.
The Five Rating Levels Under Diagnostic Code 6354
The rating schedule measures two things: how much CFS restricts your daily activities compared to your pre-illness baseline, and the total weeks per year you spend incapacitated. For rating purposes, incapacitation counts only when a physician has prescribed bed rest and treatment.1eCFR. 38 CFR 4.88b – Schedule of Ratings, Infectious Diseases, Immune Disorders and Nutritional Deficiencies
- 100% — Symptoms are nearly constant and so severe that they restrict routine daily activities almost completely, occasionally preventing basic self-care.
- 60% — Symptoms are nearly constant and restrict daily activities to less than 50 percent of the pre-illness level, or the illness waxes and wanes with incapacitation totaling at least six weeks per year.
- 40% — Symptoms are nearly constant and restrict daily activities to between 50 and 75 percent of the pre-illness level, or incapacitation totals at least four but less than six weeks per year.
- 20% — Symptoms are nearly constant and restrict daily activities by less than 25 percent of the pre-illness level, or incapacitation totals at least two but less than four weeks per year.
- 10% — Symptoms wax and wane with incapacitation totaling at least one but less than two weeks per year, or symptoms are controlled by continuous medication.
The schedule offers two tracks. A veteran whose fatigue never fully lets up is rated on how much it cuts into daily life. A veteran whose symptoms flare and subside is rated on total incapacitation time. You qualify at whichever track produces the higher rating; you don’t have to meet both.
What Each Rating Pays in 2026
The VA adjusts compensation annually. Effective December 1, 2025, a single veteran with no dependents receives the following monthly amounts:2Veterans Affairs. Veterans Disability Compensation Rates
- 10%: $180.42
- 20%: $356.66
- 40%: $795.84
- 60%: $1,435.02
- 100%: $3,938.58
Veterans with dependents receive higher amounts at ratings of 30% and above. Special Monthly Compensation may add to the 100% figure when CFS occasionally prevents self-care.
The Diagnostic Criteria That Gate the Rating
The VA won’t assign any rating without a diagnosis that meets three requirements in 38 CFR § 4.88a.3eCFR. 38 CFR 4.88a – Chronic Fatigue Syndrome
First, the fatigue must be new onset — not lifelong — and severe enough to reduce daily activity to less than 50 percent of your normal level, sustained for at least six continuous months.
Second, doctors must rule out every other clinical condition that could explain the symptoms, using your medical history, physical examination, and lab tests. If testing reveals a thyroid disorder, sleep apnea, or another explanation for the fatigue, the VA won’t grant a CFS diagnosis.
Third, medical records must document at least six of these ten symptoms:
- Acute onset of the illness
- Low-grade fever
- Sore throat without visible pus or discharge
- Tender lymph nodes in the neck or armpits
- Muscle aches or weakness
- Post-exertional fatigue lasting 24 hours or more
- Headaches that differ in type, severity, or pattern from any you had before becoming ill
- Migratory joint pain
- Neuropsychological symptoms such as difficulty concentrating, forgetfulness, or confusion
- Sleep disturbance
The six-of-ten threshold is where many claims fail. If your records document only three or four qualifying symptoms, the examiner cannot confirm the diagnosis no matter how disabling your fatigue feels. Ask your treating physician to document every symptom you experience, including ones that seem minor.
Gulf War Veterans and the December 31, 2026 Deadline
Service in the Southwest Asia theater of operations any time from August 2, 1990 onward opens a presumptive service connection for CFS under 38 CFR § 3.317. Under the presumption, the VA accepts that your service environment caused the illness, so you don’t have to prove a direct link to a specific exposure.4eCFR. 38 CFR 3.317 – Compensation for Certain Disabilities Occurring in Persian Gulf Veterans
CFS falls under this regulation as a medically unexplained chronic multisymptom illness, together with fibromyalgia and functional gastrointestinal disorders. To qualify, symptoms must have manifested to at least a 10 percent degree of disability either during active service or by December 31, 2026. If your CFS isn’t documented at a compensable level by that date, the presumptive pathway closes and you must prove a direct service connection instead.4eCFR. 38 CFR 3.317 – Compensation for Certain Disabilities Occurring in Persian Gulf Veterans
Evidence That Wins the Rating
Every claim needs a formal diagnosis from a licensed physician that satisfies 38 CFR § 4.88a. Notes reading “patient reports fatigue” won’t work. The diagnosis has to record the severity threshold, the six-month duration, the exclusion of alternative conditions, and at least six of the ten qualifying symptoms.
If you don’t qualify for the Gulf War presumption, you also need a nexus letter — a written medical opinion stating that your CFS is at least as likely as not connected to your military service, with the reasoning laid out rather than a bare conclusion. Private physicians who write these evaluations typically charge from several hundred to several thousand dollars, so plan for that expense if VA providers cannot furnish one.
The primary application is VA Form 21-526EZ.5Veterans Affairs. About VA Form 21-526EZ Describe when the fatigue began, how it affects work and daily tasks, and whether physicians have prescribed bed rest during flare-ups. A monthly symptom log tracking frequency, duration, and severity strengthens the claim. Submit all supporting evidence together to avoid delays from piecemeal requests.6Veterans Affairs. How To File A VA Disability Claim
The C&P Exam and the Bed Rest Trap
After receiving your claim the VA will likely schedule a Compensation and Pension examination. The examiner uses a Disability Benefits Questionnaire specific to CFS and evaluates whether the diagnosis meets the regulatory criteria, which qualifying symptoms you exhibit, how often they occur, how much they restrict daily activities compared to your baseline, and how the condition affects your ability to work.7Department of Veterans Affairs. Chronic Fatigue Syndrome Disability Benefits Questionnaire
The examiner also assesses cognitive problems such as concentration difficulty, forgetfulness, and confusion. Many veterans underreport these because they don’t connect them to CFS. Say so if you experience them. The DBQ requires the examiner to document these symptoms, and they can make the difference between a 20% and a 60% rating.
One detail catches veterans off guard: only physician-prescribed bed rest counts toward the incapacitation thresholds. Days you stayed home because you couldn’t function don’t count unless a doctor formally ordered rest and documented it. If your CFS regularly forces you into bed, ask your physician to prescribe rest during flare-ups and record it in your chart.
When Your Rating Won’t Support Full-Time Work
Veterans whose CFS falls short of a 100% schedular rating but still prevents steady employment may qualify for Total Disability based on Individual Unemployability, which pays at the 100% rate.8Veterans Affairs. Individual Unemployability If You Can’t Work Schedular TDIU requires either one disability rated at 60% or more, or two or more disabilities with at least one rated at 40% and a combined rating of 70% or more.9eCFR. 38 CFR 4.16 – Total Disability Ratings for Compensation Based on Unemployability of the Individual
CFS rated at 60% meets the single-disability threshold on its own. CFS at 40% combined with other service-connected conditions reaching 70% overall also qualifies. Extraschedular TDIU is possible below those numbers but requires referral to the Director of Compensation Service.
Overlapping Conditions and Pyramiding
Under 38 CFR § 4.14, the VA won’t rate the same symptoms twice under different diagnoses.10eCFR. 38 CFR 4.14 – Avoidance of Pyramiding This matters most for veterans already service-connected for fibromyalgia, which shares muscle pain, fatigue, sleep problems, and cognitive symptoms with CFS. You can still be rated for both conditions, but only for the non-overlapping symptoms each one produces. Ask your physician to spell out which symptoms belong to which diagnosis in the medical record.
If the VA Denies Your Claim or Underrates It
Three decision review options are available, and the deadline for a Higher-Level Review or Board Appeal is one year from the date on your decision letter.11Veterans Affairs. Choosing A Decision Review Option
- A Supplemental Claim (VA Form 20-0995) is for adding new and relevant evidence the VA didn’t consider, such as an updated diagnosis or a nexus letter. There’s no deadline as long as you have new evidence.
- A Higher-Level Review (VA Form 20-0996) asks a more senior reviewer to look at the existing record for error. No new evidence is allowed. One-year deadline.
- A Board Appeal (VA Form 10182) sends the case to a Veterans Law Judge. You choose direct review, submission of additional evidence, or a hearing. One-year deadline.
The most common reason for denial of a CFS claim is failure to meet 38 CFR § 4.88a, either because too few of the ten qualifying symptoms are documented or because the examiner identified another medical explanation for the fatigue. When that’s the basis for denial, a Supplemental Claim built around stronger medical documentation is usually the most productive next step.
