Muscle Group II VA Disability Rating
Diagnostic Code 5302 · 38 CFR §4.73
What Is It?
Muscle Group II consists of the extrinsic muscles of the shoulder girdle responsible for depression of the arm from the vertical overhead position and downward rotation of the scapula. This group includes the pectoralis major (clavicular portion), latissimus dorsi, teres major, pectoralis minor, and rhomboids. These muscles are critical for pulling movements, climbing, and bringing the arm down from an overhead position. Military injuries to this group commonly result from penetrating wounds to the chest and upper back area.
Rating Criteria
| Rating | Criteria |
|---|---|
| 30% | Severe injury to the dominant arm with extensive loss and major functional impairment. Non-dominant severe is rated 20 percent. |
| 20% | Moderately severe injury to the dominant or non-dominant arm with tissue loss and impaired function. |
| 10% | Moderate injury with some loss of muscle substance or function. |
| 0% | Slight injury with minimal functional impact. |
Evidence Needed
- Service records documenting the muscle injury and treatment
- Surgical and hospital records showing extent of treatment
- Current examination of muscle strength for pulling and depression movements
- Documentation of scarring and tissue loss
- Functional statements about limitations with pulling, climbing, and reaching
C&P Exam Tips
- Demonstrate difficulty with pulling movements and lowering your arm from overhead
- Report any loss of strength compared to the uninjured side
- Show scarring on the chest or upper back from the injury
- Describe activities that are limited by the muscle damage
- Mention fatigue with repetitive use of the arm
How to File
File under DC 5302 specifying the dominant or non-dominant arm. Include the original injury records and current functional testing showing the muscle impairment.
Common Mistakes
Not differentiating between dominant and non-dominant arm ratings Failing to bring original injury documentation that establishes the severity Not having current strength testing performed for the specific muscle functions Missing associated nerve injuries that should be rated separately
Frequently Asked Questions
What type of injuries typically affect Muscle Group II?
Penetrating wounds to the chest wall and upper back area from shrapnel, gunshot wounds, or blast fragments are the most common causes. Training injuries involving heavy lifting or falls can also damage these muscles, though penetrating wounds typically receive higher severity classifications.
Can I be rated for both a muscle injury and a joint condition in the same area?
VA generally avoids rating both the muscle and the joint condition separately if they cause the same functional limitation. However, if the muscle injury and joint condition produce distinct symptoms, separate ratings may be possible.
