Chronic Fatigue Syndrome Nexus Letters

Being tired all the time is not chronic fatigue syndrome.

A psychiatrist-written medical opinion — for veterans who genuinely meet the CFS criteria and need the diagnosis and connection properly documented.

What CFS Requires

A diagnosis of exclusion with a specific symptom cluster

Chronic fatigue syndrome is not simply persistent tiredness. It is a diagnosis of exclusion that requires ruling out other causes of fatigue and the presence of a specific cluster of symptoms — sustained for at least six months — that meaningfully restricts daily activity.

How CFS Connects

Pathways to service connection

  • Secondary to service-connected PTSD, anxiety, or depression
  • Presumptive for Gulf War / Southwest Asia theater veterans under 38 CFR 3.317
  • Direct connection when symptoms onset in service and were documented
  • Aggravation of pre-existing fatigue by a service-connected condition

How VA Rates CFS

Diagnostic Code 6354

CFS is rated at 10%, 20%, 40%, 60%, or 100% (there is no 30% or 50%), based on how much symptoms restrict daily activity or how many weeks of physician-prescribed incapacitation occur per year.

Considering a CFS claim — direct, secondary, or presumptive?

A psychiatrist who can tell CFS from psychiatric fatigue, and a former VA C&P examiner who knows the standard.
