Home › Conditions › Restless Leg Syndrome
Restless leg syndrome has no diagnostic code of its own and is rated by analogy — which makes the choice of code, and the evidence of severity, the whole claim. This guide quotes the actual rating criteria from 38 CFR Part 4 for diagnostic code 8103 (analogous), explains what the C&P examiner measures, covers the presumptive and secondary routes to service connection, and lists the reasons these claims come back denied — and how each gets fixed.
How the VA rates restless leg syndrome in 2026 — the exact criteria
These are the criteria a VA rater applies, quoted from the rating schedule (§ 4.124a (analogous)). Your rating is the highest level whose wording your evidence meets — and evidence that never uses these words tends to be rated at the bottom.
Restless leg syndrome — no dedicated code; rated by analogy (§ 4.20), most often to DC 8103 convulsive tic
| Rating | Criteria (38 CFR Part 4 wording) |
|---|---|
| 30% | Severe |
| 10% | Moderate |
| 0% | Mild |
DC 8103 is rated "depending upon frequency, severity, muscle groups involved." Some raters instead analogize to peripheral nerve codes or to a sleep disturbance; the choice of analogous code is itself something a supplemental claim or HLR can challenge.
RLS is commonly claimed secondary to PTSD/depression and their medications, to iron-deficiency, to kidney disease, or to lumbar radiculopathy.
Honest ceiling: severe, medication-dependent — per-leg analog ratings when supported.
What the C&P examiner measures
There is no RLS DBQ; the examiner uses a neurological or sleep DBQ and records frequency, severity, sleep disruption and treatment (dopamine agonists, gabapentin). Describe how many nights per week and what it does to your sleep and next-day function.
The questions that get at the rating criteria — answer them for yourself before the exam:
- What happens if you skip the pill — how long before the legs start?
- One leg or both? They can rate them separately.
- What does it do to your sleep?
Service connection: presumptive, direct, or secondary
No presumption. Most often claimed secondary to PTSD/depression and their medications, lumbar radiculopathy, kidney disease, or iron-deficiency related to a connected condition.
Every service-connection claim has three legs: a current diagnosis (the C&P exam can supply it), an in-service event, injury, exposure or an already-connected condition, and a link between the two — which the VA's own examiner addresses at the exam for direct and secondary claims, and which the law supplies for presumptive ones. You do not need a private opinion to file; you need one only if the VA denies for lack of nexus, and a supplemental claim within one year keeps your effective date.
Secondary conditions veterans miss
This condition is more often the secondary in a chain than the anchor — see the secondary-claims guides for the recognized pathways.
What the medical literature says
Clinical psychopharmacology literature + FDA labeling on serotonergic antidepressants
SSRIs/SNRIs are documented to induce or worsen restless leg syndrome. Why it matters: RLS secondary to MH medication; otherwise direct onset/continuity.
Why restless leg syndrome claims get denied — and the fix
- Rated 0 or 10 percent by analogy to a code that never fit — a supplemental claim can argue the analogous code and severity.
A denial is a grade on the evidence packet, not a verdict on you. Filed as a supplemental claim within one year, the fix keeps your original effective date.
Filing it right the first time
- Intent to File first. It locks your effective date for a year — back pay runs from that day, not from the day the package is ready.
- File everything at once. Every condition with a real symptom and a plausible route — direct, presumptive, secondary, increase — goes in one claim. The VA's duty to assist schedules the exam and pulls your records; a condition held back "for more evidence" only starts its clock later.
- Your statement in the criteria's words. A Statement in Support of Claim (VA Form 21-4138) that describes your worst days and your typical days using the language in the table above is the evidence the rater reads first.
- Your records. VA records through Blue Button, decision letters and code sheet from VA.gov, and private records from each doctor's office or patient portal — or a signed 21-4142 so the VA pulls them.
- Prepare for the exam. Know what the examiner measures (above) and answer honestly, including the bad days.

What is the VA rating for restless leg syndrome?
Restless Leg Syndrome is rated under diagnostic code 8103 (analogous) (§ 4.124a (analogous)) at 0%, 10%, 30%. The percentage depends on which criteria in the rating schedule your evidence meets — the full table is on this page.
What is the highest VA rating for restless leg syndrome?
The highest schedular rating available is 30%. Every case is decided on its own evidence.
Is restless leg syndrome a presumptive condition?
No presumption. Most often claimed secondary to PTSD/depression and their medications, lumbar radiculopathy, kidney disease, or iron-deficiency related to a connected condition.
Do I need a nexus letter for restless leg syndrome?
Not to file. The VA's duty to assist schedules a C&P exam where its own examiner addresses the connection, and presumptive conditions need no opinion at all. A private opinion becomes worth buying only if the VA denies for lack of nexus — a supplemental claim within one year keeps your original effective date.
