Secondary Condition Claim · VASRD 6354
Chronic Fatigue Syndrome (CFS) Secondary to Fibromyalgia
A condition caused or aggravated by an already service-connected disability can be granted its own service connection as a secondary condition under 38 CFR § 3.310. Here's how that works for Chronic Fatigue Syndrome (CFS) when it develops after Fibromyalgia.
Why Chronic Fatigue Syndrome (CFS) Is Linked to Fibromyalgia
Persistent pain often leads to exhaustion
Primary condition · VASRD 5025
Fibromyalgia
Fibromyalgia is a chronic pain condition marked by widespread musculoskeletal pain and tender points, usually with fatigue, unrefreshing sleep, stiffness and cognitive fog. VA rates it under DC 5025, and the percentage turns on how much of the time the pain is present and whether medication or therapy controls it — not on how many joints are involved.
Secondary condition · VASRD 6354
Chronic Fatigue Syndrome (CFS)
CFS causes persistent fatigue not improved by rest and worsened by physical or mental activity.
Chronic Fatigue Syndrome (CFS) VA Rating Tiers
The VA rates Chronic Fatigue Syndrome (CFS) the same way whether it's claimed directly or as secondary to Fibromyalgia — severity of Chronic Fatigue Syndrome (CFS) itself determines the percentage.
| Rating | Criteria |
|---|---|
| 100% | You can’t perform any regular activity due to extreme fatigue. |
| 60% | You're only able to function about half the time due to fatigue. |
| 40% | Significant exhaustion that limits what you can do most days. |
| 20% | Chronic tiredness that limits your lifestyle and function. |
| 10% | Occasional fatigue that interferes with daily tasks. |
Example combined rating
20% Fibromyalgia + 40% Chronic Fatigue Syndrome (CFS) = 52%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 20% and 40% combine to 52%, not 60%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
