# Amputation Not Improvable by Prosthesis Controlled by Natural Knee Action

**Diagnostic Code 5164 · Musculoskeletal System · 38 CFR § 4.71a**

## Understanding This Condition

This VA rating covers a leg amputation where the residual limb cannot be improved by a prosthesis that is controlled by natural knee action. In practical terms, this refers to amputations severe enough that the natural function of the knee cannot be used to operate a prosthetic device.

Because this rating falls under the Musculoskeletal System, it is evaluated according to the standards set out in 38 CFR § 4.71a.

## Available Rating Level

The VA rating schedule provides the following level for this condition:

| Rating | Criteria |
|--------|----------|
| **60%** | Amputation not improvable by prosthesis controlled by natural knee action |

## What the VA Looks For

When evaluating a claim under Diagnostic Code 5164, the VA focuses on whether the amputation is one that cannot be improved by a prosthesis controlled by natural knee action. Meeting this criterion supports the assignment of the 60% rating shown above.

## Additional Note

An amputation rated under this code may also entitle a veteran to **special monthly compensation** (as indicated in the rating schedule notes).
