Multiple Sclerosis

DC 8018Neurological38 CFR 4.124a, DC 8018 — Multiple Sclerosis

A disease where the immune system attacks the protective covering of nerves, causing communication problems between the brain and the rest of the body. The VA assigns a minimum 30% rating for MS and may rate individual symptoms separately.

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 8018

Rating range

30% – 100%

Rating levels

Rating criteria are defined in 38 CFR 4.124a, DC 8018 — Multiple Sclerosis. 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 MS causes severe functional impairment. You may be unable to walk, have significant cognitive problems, or require assistance with daily activities.

What the VA looks for

Severe neurological deficits
Inability to walk or severe gait impairment
Significant cognitive impairment
Requires assistance with activities of daily living
Frequent exacerbations or hospitalizations
Wheelchair or mobility aid dependent

Common Pitfalls

⚠MS has a minimum 30% rating and a 7-year presumptive period from separation. If you develop MS within 7 years of leaving service, you do not need a nexus letter.
⚠Not filing for each residual condition separately — MS can cause vision problems, bladder dysfunction, numbness, weakness, fatigue, depression, and cognitive issues, each rated under its own code and combined.
⚠Not documenting relapse frequency and severity — MS often follows a relapsing-remitting pattern. Keep records of every flare-up.
⚠Not applying for TDIU (Total Disability based on Individual Unemployability) if MS prevents you from working, even if your combined rating is below 100%.
⚠Not getting regular MRI scans and neurological evaluations to document disease progression.
