Multiple Sclerosis (MS)
Multiple sclerosis is an autoimmune disease that damages nerve insulation in the brain and spinal cord, causing fatigue, weakness, vision problems, numbness, and mobility issues. VA assigns a minimum 30 percent rating and can rate each residual separately when that yields more.
Presumptive condition — 7-year presumption (38 CFR 3.307(a)(3), 3.309(a))
MS is presumed service-connected if it manifested to a degree of at least 10 percent within 7 years after separation from service. Early symptoms (numbness, vision episodes, fatigue) documented in that window count even if the formal diagnosis came years later.
How the VA rates it
DC 8018 carries a minimum rating of 30 percent once service connection is established with ascertainable residuals. Alternatively, VA rates each MS residual under its own body system code - impaired motor function in each extremity (peripheral nerve codes), visual impairment, bladder and bowel dysfunction, fatigue, cognitive and mood changes - and combines them when the result exceeds 30 percent. MS has a special service-connection rule: it is presumed service-connected if it became at least 10 percent disabling within 7 years after separation, even if first diagnosed later.
Rating criteria by percentage
Rated up to 100%Minimum rating for service-connected multiple sclerosis with ascertainable residuals. When individual residuals (limb weakness, vision loss, bladder dysfunction, cognitive impairment, etc.) are rated separately and combine to more than 30 percent, the higher combined evaluation applies - advanced MS can reach 100 percent combined.
Secondary condition strategy
Commonly claimed secondary to this
Conditions veterans often develop from this one — each can be its own rating under 38 CFR 3.310.
- Major Depressive Disorder — Depression is common with MS and is rated separately under the mental disorders schedule.
- Urinary Frequency — Neurogenic bladder is a classic MS residual rated separately under the genitourinary schedule.
- Erectile Dysfunction — ED from MS-related nerve damage is ratable separately (usually 0 percent plus special monthly compensation).
Evidence that strengthens this claim
- For the 7-year presumption, gather any medical or lay evidence of early symptoms after separation - transient numbness, optic neuritis, unexplained fatigue - even if MS was not yet diagnosed.
- List every residual on the claim: weakness in each limb, vision problems, bladder/bowel issues, cognitive changes, depression. Separate ratings combine above the 30 percent minimum.
- MRI reports and neurologist records establishing the diagnosis and tracking exacerbations are the core medical evidence.
- File for increase during or after significant relapses, and consider special monthly compensation for loss of use of extremities or aid and attendance.
Rating rules to know
You get the 30 percent minimum OR the combined rating of separately rated residuals, whichever is higher - the same manifestation cannot be counted under two codes.

Migraine Headaches
Migraines are recurring severe headaches, often with nausea and light sensitivity. VA rates them entirely on how often you have 'prostrating' attacks - attacks so severe you must stop what you are doing and lie down.
Rated up to 50%
Sciatic Radiculopathy (Lower Extremity)
Sciatic radiculopathy is nerve pain, numbness, tingling, or weakness radiating from the low back down the leg, usually caused by a spine condition pressing on the sciatic nerve root. VA rates it per leg based on how severe the nerve impairment is.
Rated up to 80%
Peripheral Neuropathy
Peripheral neuropathy is nerve damage in the feet, legs, or hands causing burning pain, numbness, tingling, and weakness - most often from diabetes. There is no single diagnostic code: VA rates each affected nerve in each extremity separately.
Rated up to 80%
Upper Extremity Radiculopathy (Cervical Radiculopathy)
Cervical radiculopathy is pain, numbness, tingling, or weakness radiating from the neck into the shoulder, arm, or hand from a compressed nerve root. VA rates it per arm, with higher percentages for your dominant (major) arm.
Rated up to 70%
Carpal Tunnel Syndrome
Carpal tunnel syndrome is compression of the median nerve at the wrist, causing numbness, tingling, and weakness in the hand. VA rates it per wrist under the median nerve code, with higher percentages for your dominant hand.
Rated up to 70%
Traumatic Brain Injury (TBI) Residuals
TBI residuals are the lasting effects of a head injury - problems with memory, concentration, mood, headaches, dizziness, and more. VA rates TBI with a unique facet-based system where your single worst area of impairment sets the rating.
