VA Disability Rating: Muscle Injuries — Group VII (Diagnostic Code 5307)
Understanding Muscle Group VII Injuries
Muscle Group VII covers the muscles responsible for flexion of the wrist and fingers. These are the muscles that arise from the internal condyle of the humerus, including the flexors of the carpus (wrist), the long flexors of the fingers and thumb, and the pronator.
Injuries to this muscle group can affect the ability to bend the wrist and fingers, as well as rotate the forearm. The VA rates these injuries under 38 CFR § 4.73, which addresses muscle injuries.
An important factor in this rating is whether the injury affects your dominant ("major") or non-dominant ("minor") arm. Ratings for the non-dominant extremity are assigned differently at the higher severity levels.
Available Rating Levels
The VA assigns a rating based on the severity of the muscle injury. The percentage depends on both the level of severity and whether the affected arm is dominant or non-dominant.
| Criteria | Dominant Extremity | Non-Dominant Extremity |
|---|---|---|
| Severe | 40% | 30% |
| Moderately Severe | 30% | 20% |
| Moderate | 10% | 10% |
| Slight | 0% | 0% |
What the VA Looks For
When rating an injury to Muscle Group VII, the VA evaluates the severity of the muscle injury and classifies it as slight, moderate, moderately severe, or severe. The VA also considers which arm is affected — the dominant (major) or non-dominant (minor) extremity — since this affects the rating assigned at the more severe levels.
These criteria are a rendering of § 4.73, diagnostic code 5307. The official version is the one that governs your rating.
