Chronic Fatigue Syndrome (CFS) Secondary to Leg Amputation Not Improvable by Prosthesis Controlled by Natural Knee Action
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 Leg Amputation Not Improvable by Prosthesis Controlled by Natural Knee Action.
Why Chronic Fatigue Syndrome (CFS) Is Linked to Leg Amputation Not Improvable by Prosthesis Controlled by Natural Knee Action
Mobility loss increases energy use for basic movement
Primary condition · VASRD 5164
Leg Amputation Not Improvable by Prosthesis Controlled by Natural Knee Action
This code covers a below-knee amputation that a prosthesis controlled by the veteran's own knee action cannot improve — most often because the residual stump is too short to drive one. It carries a single evaluation. An amputation through the thigh itself is a different level and is rated under the thigh codes, 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.
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 Leg Amputation Not Improvable by Prosthesis Controlled by Natural Knee Action — 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
60% Leg Amputation Not Improvable by Prosthesis Controlled by Natural Knee Action + 40% Chronic Fatigue Syndrome (CFS) = 76%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 60% and 40% combine to 76%, not 100%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
