Chronic fatigue syndrome (CFS) VA Rating
How VA rates Chronic fatigue syndrome (CFS) under diagnostic code 6354, what evidence decides the percentage, and the reasons these claims get denied or under-rated.
Chronic fatigue syndrome (CFS) is rated under diagnostic code 6354. In the VA Schedule for Rating Disabilities it appears as Chronic fatigue syndrome (CFS), within the Infectious Diseases section of 38 CFR Part 4.
The essentials
| Diagnostic code | 6354 |
|---|---|
| Rating schedule name | Chronic fatigue syndrome (CFS) |
| Body system | Infectious Diseases |
| Examination form | RHEUM Chronic fatigue syndrome |
What evidence decides the rating
For infectious diseases conditions, these are the findings VA weighs when assigning a percentage. If your examination did not address them, the examination may be inadequate for rating purposes — which is itself an argument on appeal.
- Whether the disease is active or resolved, and what residuals remain
- For chronic fatigue syndrome: debilitating fatigue that reduces daily activity to less than 50% of pre-illness level, and whether it is incapacitating
Why these claims get denied or under-rated
These are the failure patterns we see most often on chronic fatigue syndrome (cfs) and related infectious diseases claims:
- Residuals were never separately rated after the active disease resolved
- Undiagnosed illness and Gulf War presumptive pathways were not considered
Secondary service connection
Under 38 CFR §3.310, a condition caused or aggravated by an already service-connected condition is itself service-connected. Secondary claims are where most veterans are leaving compensation on the table — and where most denials turn on the nexus opinion rather than the diagnosis.
Chronic fatigue syndrome (CFS) is commonly claimed secondary to
- Gulf War undiagnosed illness presumptives
- Post-infectious sequelae
Chronic fatigue syndrome (CFS) commonly causes or aggravates
- Depression
- Cognitive impairment
If you are already service-connected for chronic fatigue syndrome (cfs) and any of these apply to you, they may be claimable as secondary conditions.
If your claim was denied or under-rated
A denial is not the end of the claim. Which route is right depends on why VA decided the way it did:
- Higher-Level Review — when the evidence already in the file supports a grant and VA got the decision wrong, or the examination was inadequate.
- Supplemental Claim — when you have new and relevant evidence, such as a private nexus opinion.
- Board Appeal — when you need a Veterans Law Judge to decide, or want a hearing.
- Clear and Unmistakable Error — when a decision more than a year old contains an undebatable error, which can recover retroactive pay.
Effective dates matter as much as the percentage. See effective dates and back pay for how far back an award can reach.
