## What Is Avitaminosis?

Avitaminosis is a condition caused by a deficiency of one or more vitamins. It falls under the VA's rating category for Infectious Diseases, Immune Disorders and Nutritional Deficiencies.

Under Diagnostic Code 6313, the VA assigns a disability rating based on the severity and combination of symptoms a veteran experiences — ranging from a confirmed diagnosis with nonspecific symptoms at the lower end, up to marked physical and mental deterioration at the highest level.

---

## Available Rating Levels

The VA rates avitaminosis at one of five levels. Each level reflects an increasing range and severity of symptoms.

### 100%
Marked mental changes, moist dermatitis, inability to retain adequate nourishment, exhaustion, and cachexia.

### 60%
With all of the symptoms listed at the 40% level, plus mental symptoms and impaired bodily vigor.

### 40%
With stomatitis, diarrhea, and symmetrical dermatitis.

### 20%

## What the VA Looks For

When rating avitaminosis under Diagnostic Code 6313, the VA considers:

- **A confirmed diagnosis** of the condition, which is the foundation for the 10% level along with nonspecific symptoms.
- **The specific symptoms present**, such as stomatitis, achlorhydria, and diarrhea, which factor into the 20% and 40% levels.
- **Combinations of symptoms** — for example, stomatitis, diarrhea, and symmetrical dermatitis together at the 40% level.
- **Mental symptoms and impaired bodily vigor**, which distinguish the 60% level.
- **The most severe presentations**, including marked mental changes, moist dermatitis, inability to retain adequate nourishment, exhaustion, and cachexia, which correspond to the 100% level.
