# VA Disability Rating for Parasitic Diseases (Not Otherwise Specified)

**Diagnostic Code 6320 · 38 CFR § 4.88b**
*Body System: Infectious Diseases, Immune Disorders and Nutritional Deficiencies*
*Rated under the General Rating Formula for Infectious Diseases*

## What This Condition Covers

Diagnostic Code 6320 addresses **parasitic diseases that are not specifically listed elsewhere** in the VA rating schedule. Parasitic infections can affect the body in a wide range of ways, from active infection to lingering symptoms and complications that touch different organ systems.

Because the effects of a parasitic disease can vary so widely, the VA uses the **General Rating Formula for Infectious Diseases** to assign a rating. In general, this means:

- **Active disease** is recognized at the highest level.
- As the disease resolves, any **residual (lasting) disability** left behind by the infection is rated under the body system it affects.

> **Note:** Any residual disability of the infection is rated under the appropriate body system.

---

## Available Rating Levels

The rating levels below reflect the criteria associated with this code. Ratings range from **0% to 100%**, generally reflecting whether the disease is active and how severe the symptoms and lasting effects are.

### 100% — Active Disease and Most Severe Presentations
A 100% rating applies to **active disease**, and to the most severe presentations, which may include:

- Marked mental changes, moist dermatitis, inability to retain adequate nourishment, exhaustion, and cachexia
- Congestive heart failure, anasarca, or Wernicke-Korsakoff syndrome
- Acute disease with frequent exacerbations producing severe impairment of health
- Symptoms that are nearly constant and so severe as to restrict routine daily activities almost completely, and which may occasionally preclude self-care

### 60%
- All of the symptoms listed for lower levels, plus mental symptoms and impaired bodily vigor
- Cardiomegaly, or peripheral neuropathy with footdrop or atrophy of thigh or calf muscles
- Exacerbations lasting a week or more, 2 or 3 times per year
- Symptoms that are nearly constant and restrict routine daily activities to less than 50 percent of the pre-illness level; or that wax and wane, resulting in periods of incapacitation of at least six weeks total duration per year

### 40%
- Stomatitis, diarrhea, and symmetrical dermatitis
- Symptoms that are nearly constant and restrict routine daily activities from 50 to 75 percent of the pre-illness level; or that wax and wane, resulting in periods of incapacitation of at least four but less than six weeks total duration per year

### 30%
- Peripheral neuropathy with absent knee or ankle jerks and loss of sensation, or symptoms such as weakness, fatigue, anorexia, dizziness, heaviness and stiffness of legs, headache or sleep disturbance

### 20%
- Stomatitis, or achlorhydria, or diarrhea
- Symptoms that are nearly constant and restrict routine daily activities by less than 25 percent of the pre-illness level; or that wax and wane, resulting in periods of incapacitation of at least two but less than four weeks total duration per year

### 10%
- Confirmed diagnosis with nonspecific symptoms such as decreased appetite, weight loss, abdominal discomfort, weakness, inability to concentrate, and irritability
- Exacerbations once or twice a year, or symptomatic during the past 2 years
- Symptoms that wax and wane but result in periods of incapacitation of at least one but less than two weeks total duration per year; or symptoms controlled by continuous medication

### 0%
- Acute or asymptomatic chronic disease

## What the VA Looks For

When rating a parasitic disease under Diagnostic Code 6320, the VA generally considers:

- **Whether the disease is currently active.** Active disease is recognized at the 100% level.
- **The specific symptoms present**, such as stomatitis, diarrhea, dermatitis, achlorhydria, or nonspecific symptoms like weight loss, weakness, and difficulty concentrating.
- **The severity and complications**, including mental changes, nutritional problems, cardiac effects, or peripheral neuropathy.
- **How much the condition restricts routine daily activities**, and whether symptoms are nearly constant or wax and wane.
- **Periods of incapacitation** measured over the course of a year.
- **Whether symptoms are controlled by continuous medication.**
- **Any residual disability** left by the infection, which is rated under the appropriate body system.
