# Syphilis and Other Treponema Infections (VA Diagnostic Code 6310)

*Rated under 38 CFR § 4.88b — Infectious Diseases, Immune Disorders and Nutritional Deficiencies*

## Understanding This Condition

Syphilis and other treponema infections are addressed under VA Diagnostic Code 6310. What sets this diagnostic code apart is that it does not carry its own set of percentage rating levels. Instead, the VA rates the **residual disability** — the lasting effects the infection leaves behind on the body.

Because a treponema infection can affect many different parts of the body, the VA looks at where the impact shows up and applies the rating criteria for that specific body system.

## How the VA Rates It

There is no standalone percentage ladder for Diagnostic Code 6310. Any residual disability from the infection is rated under the appropriate body system. According to the criteria, this includes, but is not limited to:

- **Diseases of the nervous system**
- **Diseases of the vascular system**
- **Diseases of the eyes**
- **Diseases of the ears**

The regulation directs raters to the relevant diagnostic codes for these residual conditions:

- **DC 7004**
- **DC 8013**
- **DC 8014**
- **DC 8015**
- **DC 9301**

## What the VA Looks For

When evaluating a claim under Diagnostic Code 6310, the VA focuses on identifying the residual disability caused by the infection and matching it to the correct body system. Rather than rating the infection itself with a fixed percentage, the VA assesses the ongoing effects — such as impacts on the nervous system, vascular system, eyes, or ears — and applies the rating criteria for that condition using the referenced diagnostic codes.
