Muscle Group I - Shoulder Girdle Muscles (Trapezius, Levator Scapulae)
Injury to the muscles that rotate the shoulder blade upward and raise the arm above shoulder level — the trapezius, levator scapulae and serratus magnus.
The VA rates Muscle Group I - Shoulder Girdle Muscles (Trapezius, Levator Scapulae) the same way whether it's claimed directly or as secondary to Upper Radicular Group (Nerve Damage) — severity of Muscle Group I - Shoulder Girdle Muscles (Trapezius, Levator Scapulae) itself determines the percentage.
| Rating | Criteria |
|---|---|
| 40% | Severe damage to the shoulder-girdle muscles of your dominant arm. |
| 30% | Severe damage on your non-dominant side, or moderately severe damage on your dominant side. |
| 20% | Moderately severe damage to the shoulder-girdle muscles of your non-dominant arm. |
| 10% | Moderate damage to these muscles — rated the same whichever arm is injured. |
| 0% | Slight damage — service-connected, but below the level the schedule pays for. |
Example combined rating
40% Upper Radicular Group (Nerve Damage) + 20% Muscle Group I - Shoulder Girdle Muscles (Trapezius, Levator Scapulae) = 52%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 40% and 20% combine to 52%, not 60%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
