Multiple sclerosis

Multiple sclerosis (MS) is a disease of the brain and spinal cord that the VA formally recognizes as a service-connectable disability. The VA can grant service connection if your records show MS began during service or was caused by service, or — for many veterans — through a special "presumptive" path that does not require proving a direct cause.

The VA rates MS under its schedule for neurological conditions, 38 CFR § 4.124a, using Diagnostic Code 8018, which sets a minimum rating of 30 percent. From there, the rating can scale higher based on how MS affects each part of the body — for example, weakness, vision problems, bladder issues, or trouble with balance and thinking can each be evaluated under the related rules, so the overall rating reflects the full picture of the symptoms.

MS is also one of the "chronic diseases" the VA lists for presumptive service connection. Under 38 CFR §§ 3.307 and 3.309(a), if MS becomes noticeable to a compensable degree (at least 10 percent) within 7 years of leaving service, the VA may presume it is connected to service even without direct proof of cause. That 7-year window is longer than the one-year window most chronic diseases get, which can help veterans whose MS symptoms took time to appear.

This is general educational information about how the VA's rules work — not legal advice, not a VA decision, and not a prediction about any individual claim. Outcomes depend on your own facts and evidence; a denial can be appealed.
