Secondary Condition Claim · VASRD 5301
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 Muscle Group I - Shoulder girdle muscles when it develops after Upper Radicular Group (Nerve Damage).
Due to lack of use
Primary condition · VASRD 8510
Upper Radicular Group (Nerve Damage)
Damage to the upper nerves in the shoulder, affecting arm and neck movement.
Secondary condition · VASRD 5301
Muscle Group I - Shoulder girdle muscles
Damage to muscles that stabilize the shoulder joint.
The VA rates Muscle Group I - Shoulder girdle muscles 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 itself determines the percentage.
Example combined rating
30% Upper Radicular Group (Nerve Damage) + 20% Muscle Group I - Shoulder girdle muscles = 44%
The VA combines ratings with Table I of 38 CFR 4.25, not simple addition — 30% and 20% combine to 44%, not 50%. These figures are illustrative; your actual rating for each condition depends on your own evaluation.
