Understanding how the VA rates a convulsive tic disorder under the disability rating schedule.

## What This Condition Is

A convulsive tic is a neurological condition involving involuntary muscle movements. Under the VA rating schedule, it is classified within **Neurological Conditions and Convulsive Disorders** and evaluated under **Diagnostic Code 8103** (38 CFR § 4.124a).

## Available Rating Levels

The VA assigns a disability rating based on the overall severity of the condition. For convulsive tic, the following rating levels are available:

| Rating | Severity |
|--------|----------|
| **30%** | Severe |
| **10%** | Moderate |
| **0%** | Mild |

A 0% (noncompensable) rating means the condition is recognized as service-connected but is rated at the mild level.

## What the VA Looks For

When rating a convulsive tic, the VA evaluates the condition based on:

- **Frequency** of the tics
- **Severity** of the tics
- **Muscle groups involved**

These factors together help determine whether the condition is rated as mild, moderate, or severe.
