Paralysis of the Upper Radicular Group (Fifth and Sixth Cervicals) — VA Diagnostic Code 8510

Neurological Conditions and Convulsive Disorders • 38 CFR § 4.124a • Diagnostic Code 8510

Understanding This Condition

The upper radicular group refers to the nerves originating from the fifth and sixth cervical (neck) nerve roots. Paralysis affecting this group primarily impacts movement at the shoulder and elbow. Under VA Diagnostic Code 8510, this condition is evaluated based on whether the paralysis is complete or incomplete, and — when incomplete — how severe the impairment is.

The VA also considers which arm is affected. Ratings differ depending on whether the paralysis affects the dominant (major) extremity or the non-dominant (minor) extremity, with the non-dominant side generally assigned a slightly lower percentage.

Available Rating Levels

Ratings for this condition are assigned across the following levels:

Rating (Dominant Arm)Rating (Non-Dominant Arm)Description
70%60%Complete: all shoulder and elbow movements lost or severely affected; hand and wrist movements not affected
50%40%Incomplete — Severe
40%30%Incomplete — Moderate
20%20%Incomplete — Mild

What the VA Looks For

When rating paralysis of the upper radicular group, the VA evaluates:

  • Whether the paralysis is complete or incomplete. A complete rating reflects that all shoulder and elbow movements are lost or severely affected, while hand and wrist movements remain unaffected.
  • The severity of incomplete paralysis, categorized as mild, moderate, or severe.
  • Which extremity is affected — the dominant (major) or non-dominant (minor) arm — as this influences the assigned percentage.

This information is drawn directly from the VA rating schedule under 38 CFR § 4.124a. It is intended to help you understand how this condition is described and rated. It does not predict any individual outcome or constitute legal advice.

These criteria are a rendering of § 4.124a, diagnostic code 8510. The official version is the one that governs your rating.

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 8510 and attach the evidence for the level you are asking for. Other Neurological Conditions and Convulsive Disorders codes may cover your secondary conditions.
