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.

Rating Levels

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.
