Body system: Neurological Conditions and Convulsive DisordersRegulation: 38 CFR § 4.124aDBQ: DBQ NEURO Peripheral Nerves
DC 8517, paralysis of musculocutaneous nerve, is rated by the level below that matches your condition; the dominant (major) arm is rated higher than the non-dominant (minor) arm at the upper levels. The levels: Complete; weakness but not loss of flexion of elbow and supination of forearm: 30% for the dominant arm, 20% for the non-dominant arm. Incomplete, severe: 20% for either arm. Incomplete, moderate: 10% for either arm. Incomplete, mild: 0% for either arm.
Rating levels
- 30% — Complete damage to this nerve causes weakness in your ability to bend your elbow and turn your palm upward (supination), but you haven't completely lost these movements. You can still bend your elbow and rotate your forearm to some degree, just not with normal strength.
- 20% — The musculocutaneous nerve is completely damaged, but you still have some ability to bend your elbow and rotate your forearm palm-up (supination), though these movements are noticeably weaker than normal. You haven't completely lost the ability to do these arm movements, but they require more effort and feel weak compared to your uninjured arm.
- 20% — You have severe damage to the musculocutaneous nerve (the nerve that controls your bicep muscle and provides feeling to part of your forearm), but the nerve still has some function remaining. This means you have significant weakness when bending your elbow and may have numbness or tingling on the outer side of your forearm, but you haven't completely lost all movement or sensation.
- 20% — You have severe damage to the musculocutaneous nerve (the nerve that controls your bicep muscle and provides feeling to part of your forearm), but the nerve still has some function remaining. This means you have significant weakness when bending your elbow and may have numbness or tingling on the outer side of your forearm, but you haven't completely lost all movement or sensation.
- 10% — The musculocutaneous nerve (a nerve that controls your bicep muscle and provides feeling to part of your forearm) has moderate damage but still works partially. You would have noticeable weakness when bending your elbow and some numbness or tingling along the outer edge of your forearm, but you can still use the arm for most daily activities.
- 10% — The musculocutaneous nerve (a nerve that controls your bicep muscle and provides feeling to part of your forearm) has moderate damage but still works partially. You would have noticeable weakness when bending your elbow and some numbness or tingling along the outer edge of your forearm, but you can still use the arm for most daily activities.
- 0% — You have some mild damage to the musculocutaneous nerve (the nerve that controls your bicep muscle and gives feeling to part of your forearm), but the nerve still works partially. Your bicep muscle may feel slightly weak when bending your elbow or you might have some minor numbness along the outer edge of your forearm, but these symptoms don't significantly interfere with your daily activities.
- 0% — You have some mild damage to the musculocutaneous nerve (the nerve that controls your bicep muscle and gives feeling to part of your forearm), but the nerve still works partially. Your bicep muscle may feel slightly weak when bending your elbow or you might have some minor numbness along the outer edge of your forearm, but these symptoms don't significantly interfere with your daily activities.
