Raynaud's (ray-NOZ) disease is a condition characterized by episodic vasospasm — sudden, exaggerated constriction of small arteries (arterioles) in the digits — most commonly fingers, less commonly toes, ears, and nose. During an attack, the affected area turns white (pallor, due to arterial spasm cutting off blood flow), then blue (cyanosis, due to deoxygenated blood pooling), then red (reactive hyperemia as blood rushes back when the spasm releases). This tricolor sequence is the clinical hallmark.
Attacks are triggered primarily by cold exposure — even mild cold like reaching into a refrigerator, holding a cold drink, or transitioning from a warm room to air conditioning can trigger an episode. Emotional stress is a secondary trigger, mediated through the sympathetic nervous system's vasoconstrictive effects.
Clinically, Raynaud's is divided into primary (Raynaud's disease — idiopathic, no underlying cause) and secondary (Raynaud's phenomenon — caused by or associated with another condition). For VA rating purposes, both are rated identically under DC 7117. However, the distinction matters for service connection:
VA rates Raynaud's syndrome under 38 CFR Part 4, Diagnostic Code 7117. The rating is driven by episode frequency and the presence of trophic changes:
| Rating | Criteria Under DC 7117 |
|---|---|
| 40% | Attacks occurring four or more times per week; or, persistent vasospastic attacks with trophic changes (digital ulcers, gangrene, atrophy, skin changes) |
| 20% | Attacks occurring one to three times per week |
| 10% | Attacks occurring less than once per week |
Under DC 7117, the rating hinges entirely on how often attacks occur. This makes accurate documentation of episode frequency the single most important task in a Raynaud's claim. If you are having 4+ attacks per week, you should receive 40%. If VA assigns only 10% or 20% without taking a proper history of attack frequency, that is a ratable error that can be corrected on appeal.
When Raynaud's affects both upper and lower extremities, or affects different digit groups asymmetrically, discuss with your claims representative whether bilateral separate ratings under extremity codes might be appropriate. In some cases, distinguishing between upper and lower extremity involvement and the cold injury laterality may support additional compensation.
Cold injury — frostbite, trench foot, immersion foot — is a well-recognized cause of permanent microvascular damage. The mechanism: extreme cold causes ice crystal formation in tissues and vascular endothelium, followed by inflammatory and thrombotic processes that damage the small vessel walls. Even after the acute cold injury resolves, the endothelial damage produces chronic vasomotor instability that manifests as Raynaud's phenomenon.
Under 38 CFR § 3.304(f), residuals of cold injuries are well-established as service-connected disabilities. VA's M21-1 adjudication manual specifically recognizes Raynaud's phenomenon as a potential residual of frostbite. This means that veterans who had documented frostbite or trench foot during service have a strong presumptive-like basis for service-connecting Raynaud's as a residual cold injury — even decades later.
See our dedicated guide on cold injuries and frostbite VA claims for the full documentation strategy.
Many cold injuries during Korean War, Cold War deployments, and even later service were never formally documented. Command cultures often discouraged injury reporting; soldiers tended to "walk off" frostbitten fingers rather than seek medical attention. Under 38 CFR § 3.303(a) and the benefit-of-the-doubt standard, VA cannot require contemporary documentation if there is no reason to doubt the veteran's credibility. Lay evidence (personal statement, buddy statements) describing the cold exposure and symptoms is acceptable evidence of the in-service event even without contemporaneous medical records.
Korean War veterans (1950–1953) served in some of the harshest cold-weather combat conditions in American military history, with winter temperatures reaching -30°F in the Korean mountains. Cold injuries were endemic — hundreds of thousands of cases documented in the U.S. Army alone. If you are a Korean War veteran with Raynaud's, even without specific STR documentation of frostbite, your service circumstances powerfully corroborate a cold injury claim. A nexus letter from a vascular specialist citing the well-documented epidemiology of cold injury sequelae in Korean War veterans strengthens the claim significantly.
Cold injury service connection is not limited to combat veterans. Veterans stationed in cold climates during training, peacetime deployments, or field exercises also had substantial cold exposure that can cause microvascular damage cumulative enough to produce Raynaud's phenomenon:
U.S. Army Europe (USAREUR) veterans stationed in Germany during the Cold War regularly conducted winter field exercises — REFORGER exercises, Hohenfels/Grafenwöhr training — in German winters. Extended time in cold, wet conditions during field problems, often without adequate cold-weather gear, produced significant cold injury exposure even without combat.
Veterans stationed at Fort Wainwright, Fort Greely, Eielson AFB, Fort Richardson (now JBER), or other Alaska installations had endemic cold exposure. Arctic and Alaskan warfare training involves deliberate cold-weather operations that routinely produce cold injuries. Arctic training command records and unit histories document these conditions.
Mountain warfare training (JRTC cold-weather rotations, NWTC at Fort McCoy), Ranger School winter phase (Camp Frank D. Merrill), and Special Forces SERE training all involve extreme cold exposure that can produce lasting vascular damage.
Raynaud's phenomenon is one of the most common manifestations of systemic autoimmune connective tissue diseases. If you have a service-connected autoimmune condition, Raynaud's is a natural secondary claim candidate:
| Primary SC Condition | Raynaud's Association |
|---|---|
| Systemic Lupus Erythematosus (SLE) | Present in 10-45% of SLE patients |
| Rheumatoid Arthritis | Present in 5-10% of RA patients |
| Scleroderma/SSc | Present in nearly 95% of SSc patients |
| Sjögren's Syndrome | Present in 13-30% of Sjögren's patients |
| Mixed Connective Tissue Disease | Present in majority of MCTD patients |
Under 38 CFR § 3.310, a secondary condition is service-connected if it is caused or chronically worsened (aggravated) by a service-connected disability. For veterans with service-connected lupus or rheumatoid arthritis, a secondary Raynaud's claim requires only a nexus opinion stating the Raynaud's is at least as likely as not caused by the primary SC condition. See our guides on lupus VA ratings and rheumatoid arthritis ratings for more on the primary conditions.
Because DC 7117 ratings hinge entirely on how often attacks occur, the documentation of episode frequency is the central task in a Raynaud's claim. General statements like "I have frequent attacks" will not be sufficient — VA needs specific frequency data.
Keep a written diary for at least 60-90 days before your C&P exam. Record:
At the C&P exam, bring this diary and offer it to the examiner. If the examiner declines to review it, submit it as evidence with a supplemental claim.
Raynaud's attacks vary dramatically by season. Summer attack frequency may be much lower than winter attack frequency. Your claim should reflect your winter/cold-season frequency (the worst case) and document seasonal variation explicitly. If you had 20+ attacks per week in February but only 1 per week in August, VA should rate you based on the worst clinical picture — the seasonal peak.
Document how Raynaud's attacks affect your work. If attacks prevent you from operating machinery, typing, performing fine motor tasks, or working outdoors, this functional limitation is highly relevant to both rating and any TDIU consideration.
The 40% rating under DC 7117 applies not only to attacks occurring 4+ times per week, but also to "persistent vasospastic attacks" with trophic changes. Trophic changes are objective physical findings caused by chronic ischemia (reduced blood flow) to the digit tissues:
Trophic changes are objective, photographable evidence. If you have any of these findings, photograph them before your C&P exam and submit the photos as evidence. A rheumatologist or vascular medicine specialist's note documenting trophic changes provides medical corroboration. If trophic changes are present, you should argue for the 40% rating regardless of attack frequency count.
In severe cases, Raynaud's with digital gangrene leads to amputation. If service-connected Raynaud's has resulted in digital amputation, the amputated digit(s) are rated under the amputation diagnostic codes (DC 5152-5156 for fingers, higher for more proximal amputations). Amputation ratings typically far exceed the DC 7117 maximum and should be claimed separately from the Raynaud's rating.
