# Muscle Injuries — Group XV (Mesial Thigh Muscles) | Diagnostic Code 5315

## Understanding a Group XV Muscle Injury Rating

Group XV covers the **mesial thigh muscle group**, located on the inner side of the thigh. These muscles are responsible for key movements of the lower body, including:

- **Adduction of the hip** (drawing the thigh inward toward the body)
- **Flexion of the hip** (bending at the hip)
- **Flexion of the knee** (bending at the knee)

The specific muscles that make up this group are:

1. **Adductor longus**
2. **Adductor brevis**
3. **Adductor magnus**
4. **Gracilis**

Injuries to these muscles can affect a person's ability to move the hip and knee. The VA rates this condition under **§ 4.73**, within the **Muscle Injuries** body system.

## Available Rating Levels

The VA assigns a disability rating based on how severe the muscle injury is. Under Diagnostic Code 5315, the available levels are:

| Rating | Level of Disability |
|--------|---------------------|
| **30%** | Severe |
| **20%** | Moderately Severe |
| **10%** | Moderate |
| **0%** | Slight |

## What the VA Looks For

When rating a Group XV muscle injury, the VA evaluates the **severity of the muscle disability**, categorizing it as *slight*, *moderate*, *moderately severe*, or *severe*. The rating level reflects how significantly the injury affects the function of the mesial thigh muscles — including the hip and knee movements these muscles control.
