Secondary Condition Claim · VASRD 6354
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 Other Specified Forms of Arthritis.
Systemic inflammation
Primary condition · VASRD 5009
Other Specified Forms of Arthritis
DC 5009 is the schedule's catch-all for inflammatory joint disease that has no code of its own — the schedule titles it "Other specified forms of arthropathy (excluding gout)" and its Note (1) lists "Charcot neuropathic, hypertrophic, crystalline, and other autoimmune arthropathies" as examples. Gout is expressly excluded: since February 7, 2021 gout is rated under DC 5017 on limitation of motion, not here.
Secondary condition · VASRD 6354
Chronic Fatigue Syndrome (CFS)
CFS causes persistent fatigue not improved by rest and worsened by physical or mental activity.
The VA rates Chronic Fatigue Syndrome (CFS) the same way whether it's claimed directly or as secondary to Other Specified Forms of Arthritis — 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
40% Other Specified Forms of Arthritis + 40% Chronic Fatigue Syndrome (CFS) = 64%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 40% and 40% combine to 64%, not 80%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
