Chronic Brain Abscess

DC 8020Neurological38 CFR 4.124a, DC 8020

A localized collection of pus within the brain tissue from infection. The VA rates chronic brain abscess based on the residual neurological deficits after treatment, such as seizures, focal weakness, cognitive impairment, or speech difficulties.

How the VA rates this condition

The VA rates this condition based on how much it affects your ability to work and carry out daily activities. The examiner will focus on the functional limitations your condition causes, not just the diagnosis itself.

Diagnostic code

DC 8020

Rating range

10% – 100%

Rating levels

Rating criteria are defined in 38 CFR 4.124a, DC 8020. This guide presents a plain-language summary and is not a substitute for the full regulatory text. Always consult a VSO or VA-accredited attorney for case-specific advice.

Rating Levels

Your brain abscess residuals are totally disabling. You may have intractable seizures, complete paralysis of one side, severe brain damage, or you require constant care and supervision.

What the VA looks for

Intractable seizures unresponsive to treatment
Complete hemiplegia
Severe brain damage with total cognitive impairment
Inability to perform activities of daily living
Requires institutional or constant nursing care

Common Pitfalls

⚠Not filing for each residual condition separately — brain abscesses can cause seizures, focal weakness, cognitive impairment, and speech problems that may each be rated under their own diagnostic codes.
⚠Not documenting the source of infection and its connection to service — brain abscesses can result from penetrating head injuries, dental infections, sinus infections, or other conditions that may be service-connected.
⚠Not maintaining regular neuroimaging follow-up — MRI surveillance documents the ongoing structural brain changes and helps establish the chronic nature of the condition.
