VA Disability Rating: Paralysis (Diagnostic Code 8517)

Neurological Conditions and Convulsive Disorders — 38 CFR § 4.124a

Understanding This Condition

Diagnostic Code 8517 addresses paralysis affecting nerve function in the upper extremity. The VA distinguishes between complete paralysis and incomplete paralysis, with incomplete cases further classified by how severe the impairment is (mild, moderate, or severe).

Because ratings under this code apply to an extremity, the VA also considers whether the affected arm is your dominant (major) or non-dominant (minor) side. In some cases, the rating for the non-dominant extremity differs from the dominant one.

Available Rating Levels

Rating (Dominant)Rating (Non-Dominant)What It Reflects
30%20%Complete; weakness but not loss of flexion of elbow and supination of forearm
20%20%Incomplete: Severe
10%10%Incomplete: Moderate
0%0%Incomplete: Mild

What the VA Looks For

When evaluating this condition, the VA reviews:

  • Whether the paralysis is complete or incomplete, which is the primary factor in placement on the rating scale.
  • The severity of incomplete paralysis — classified as mild, moderate, or severe.
  • Specific functional impacts, such as weakness in flexion of the elbow and supination of the forearm.
  • Which extremity is affected — dominant (major) or non-dominant (minor) — since the applicable percentage may differ.

Important Note

Combined nerve injuries should be rated by reference to the major involvement, or, if sufficient in extent, consider radicular group ratings.

How to claim this

Knowing the criteria is the first half. Getting your file to show them is the second.

  1. Find your level in the stack

    Read each rung against what your medical records already say. The level your records document today is the one the VA can support today.

  2. Name the gap

    Look at the rung above yours and write down exactly what it asks for that your file does not show yet — a diagnosis, a measurement, a prescribed brace, a doctor’s opinion linking it to service.

  3. Claim it by code

    File under diagnostic code 8517 and attach the evidence for the level you are asking for. Other Neurological Conditions and Convulsive Disorders codes may cover your secondary conditions.
