# DC 8000 - Encephalitis, epidemic, chronic

Rated under § 4.124a. Body system: Neurological Conditions and Convulsive Disorders.

## Rating criteria

| Rating | Criteria |
| --- | --- |
| 100% | As active febrile disease |
| 10% | Rate residuals, minimum |

## Notes

- Note: It is required for the minimum ratings for residuals under diagnostic codes 8000-8025, that there be ascertainable residuals. Determinations as to the presence of residuals not capable of objective verification, i.e., headaches, dizziness, fatigability, must be approached on the basis of the diagnosis recorded; subjective residuals will be accepted when consistent with the disease and not more likely attributable to other disease or no disease. It is of exceptional importance that when ratings in excess of the prescribed minimum ratings are assigned, the diagnostic codes utilized as bases of evaluation be cited, in addition to the codes identifying the diagnoses.

# Chronic Epidemic Encephalitis (Diagnostic Code 8000)

*Neurological Conditions and Convulsive Disorders · 38 CFR § 4.124a*

## Understanding This Condition

Chronic epidemic encephalitis is a neurological condition rated by the VA under Diagnostic Code 8000. Like other conditions in this part of the rating schedule, it can be evaluated during its active phase and, separately, based on the lasting effects (residuals) it leaves behind.

## Available Rating Levels

The VA uses the following rating levels for this condition:

| Rating | What It Reflects |
|--------|------------------|
| **100%** | As active febrile disease |
| **10%** | Rate residuals, minimum |

The 100% level applies while the condition is present as an active febrile disease. The 10% level is the minimum rating assigned for residuals of the condition.

## What the VA Looks For

When rating residuals under this diagnostic code, the VA looks for the following:

- **Ascertainable residuals are required.** To receive the minimum rating for residuals under Diagnostic Codes 8000–8025, there must be ascertainable residuals.

- **How subjective residuals are handled.** Some residuals—such as headaches, dizziness, or fatigability—may not be capable of objective verification. In these cases, the VA approaches the determination based on the diagnosis recorded. Subjective residuals are accepted when they are consistent with the disease and are not more likely attributable to another disease or to no disease.

- **Higher ratings and diagnostic code citations.** When ratings above the prescribed minimum are assigned, it is considered exceptionally important that the diagnostic codes used as the basis of evaluation be cited, in addition to the codes identifying the diagnoses.
