Presumptive Conditions for Korean War Veterans: Cold, DMZ, POWs

The VA recognizes several sets of presumptive conditions for Korean War veterans, meaning the agency will accept the link between service and the illness without the veteran proving it. Four pathways matter most: chronic diseases that appear within set timeframes after discharge for any wartime veteran; an expanded list for former prisoners of war; Agent Orange-related conditions for veterans who served in or near the Korean Demilitarized Zone between September 1, 1967, and August 31, 1971; and radiation-related cancers for atomic veterans who took part in Korean-era nuclear tests. Which list applies depends on where and how you served.

Chronic Diseases Within a Year of Discharge

Every veteran with at least 90 continuous days of wartime service — which includes Korean War service — can claim presumptive service connection for a long list of chronic diseases under 38 CFR 3.309(a), as long as the condition becomes at least 10 percent disabling within one year of leaving active duty. The list is long. Arthritis, diabetes mellitus, cardiovascular-renal disease including hypertension, peptic ulcers, epilepsies, leukemia, Hodgkin’s disease, malignant tumors, psychoses, lupus erythematosus, scleroderma, and Raynaud’s disease all qualify, among many others.¹

A handful of conditions have longer windows. Tuberculosis and Hansen’s disease (leprosy) are presumptive if they appear within three years of discharge. Multiple sclerosis is covered within seven years. ALS is presumptive at any point after discharge, with no deadline.²

For most Korean War veterans, the one-year window closed decades ago. That does not close every door — see the POW, herbicide, and radiation lists below, which have no time limit — but it means the general chronic-disease presumption is unlikely to be the pathway for a condition diagnosed today.

Cold Injury Residuals

Extreme cold was one of the defining hazards of the Korean War, particularly for troops who fought during the Chosin Reservoir Campaign from October through December 1950. The VA recognizes that cold injuries can produce long-term problems including skin cancer in frostbite scars, arthritis, fallen arches, stiff toes, cold sensitization, and pain, tingling, or numbness in the fingers and toes, and that diabetes or peripheral vascular disease later in life raises the risk of amputation.³⁴

Note the boundary: cold injury residuals are not a general presumptive condition for Korean War veterans. Under 38 CFR 3.309, “organic residuals of frostbite” is presumptive only for former POWs interned in climatic conditions consistent with frostbite.¹ Non-POW veterans who suffered cold injuries in Korea have to pursue a direct service connection claim, using service records and medical evidence to link the current condition to cold exposure during service.

Presumptive Conditions for Former Prisoners of War

Former POWs get their own list under 38 CFR 3.309(c). Conditions must reach at least 10 percent disabling, but there is no time limit — they are presumptive at any point after discharge.

Any Length of Captivity

Regardless of how long a veteran was held, these conditions are presumptively service-connected:

Psychiatric conditions: psychosis, any anxiety state (including PTSD), and dysthymic disorder (depressive neurosis)
Organic residuals of frostbite, if the veteran was interned in climatic conditions consistent with frostbite
Post-traumatic osteoarthritis
Atherosclerotic heart disease or hypertensive vascular disease and their complications, including myocardial infarction, congestive heart failure, and arrhythmia
Stroke and its complications
Osteoporosis, for claims filed on or after October 10, 2008, if the veteran has also been determined to have PTSD

Captivity of 30 Days or More

Veterans held at least 30 days qualify for an additional list reflecting prolonged malnutrition and disease:

Nutritional deficiencies: avitaminosis, beriberi (including beriberi heart disease), malnutrition (including associated optic atrophy), pellagra, and any other nutritional deficiency
Digestive disorders: chronic dysentery, irritable bowel syndrome, peptic ulcer disease, and cirrhosis of the liver
Helminthiasis (parasitic worm infection)
Peripheral neuropathy, except where directly related to infectious causes
Osteoporosis, for claims on or after September 28, 2009, with no PTSD requirement

Agent Orange for Korean DMZ Service, 1967–1971

The Korean War fighting ended in 1953, but the herbicide presumption covers a later window. Veterans who served in or near the Korean DMZ between September 1, 1967, and August 31, 1971, are presumed to have been exposed to Agent Orange and other tactical herbicides. The VA and Department of Defense verify that the veteran’s unit operated in the DMZ area during the qualifying window and that the veteran was physically present.⁵

Once that service is verified, no proof of actual herbicide contact is required. Presumptive conditions include:

Cancers: bladder cancer, chronic B-cell leukemia, Hodgkin’s disease, multiple myeloma, non-Hodgkin’s lymphoma, prostate cancer, respiratory cancers (lung, bronchus, larynx, or trachea), and some soft tissue sarcomas
Other conditions: AL amyloidosis, chloracne, type 2 diabetes mellitus, hypertension, hypothyroidism, ischemic heart disease, monoclonal gammopathy of undetermined significance (MGUS), Parkinson’s disease, parkinsonism, early-onset peripheral neuropathy, and porphyria cutanea tarda

⁶

Three of these have timing rules: chloracne, early-onset peripheral neuropathy, and porphyria cutanea tarda must reach at least 10 percent disabling within one year of exposure.⁶ Hypertension and MGUS were added to the list by the PACT Act in 2022, so veterans previously denied for either can file a Supplemental Claim for reconsideration.⁷

The PACT Act did not create new presumptive conditions specifically for combat-era Korean War service from 1950 to 1953.⁷

Spina Bifida in Children of DMZ Veterans

Biological children of veterans who served in or near the Korean DMZ during the September 1967 to August 1971 window may qualify for VA benefits if they were born with spina bifida (other than spina bifida occulta). The child must have been conceived after the veteran parent first entered the DMZ during the qualifying period. Benefits include a monthly monetary allowance based on the degree of disability, health care through the Spina Bifida Health Care Benefits Program, and vocational training through VA Veteran Readiness and Employment.⁸

Radiation Exposure for Atomic Veterans

Some Korean War-era service members took part in atmospheric nuclear weapons tests, which makes them “atomic veterans” with their own set of presumptive conditions. Test operations that overlapped the Korean War included Operation Tumbler-Snapper (April 1 through June 20, 1952) and Operation Upshot-Knothole (March 17 through June 20, 1953), both at the Nevada Proving Ground. Upshot-Knothole alone involved approximately 20,100 Department of Defense personnel, many participating in Exercise Desert Rock V.⁹

Under 38 CFR 3.309(d), veterans who participated in a radiation-risk activity — defined to include onsite participation in an atmospheric nuclear test or service at the test site for up to six months afterward for decontamination duties — are eligible for presumptive service connection for more than 20 cancers, including:

Leukemia (other than chronic lymphocytic leukemia)
Cancers of the thyroid, breast, lung, colon, stomach, esophagus, pharynx, pancreas, small intestine, bone, brain, bile ducts, gall bladder, salivary gland, ovary, and urinary tract
Primary liver cancer, except where cirrhosis or hepatitis B is indicated
Bronchiolo-alveolar carcinoma
Multiple myeloma
Lymphomas, except Hodgkin’s disease

Some other conditions are not automatically presumed but can be granted case by case with supporting evidence, including non-malignant thyroid nodular disease, parathyroid adenoma, and posterior subcapsular cataracts.¹⁰

One Common Condition That Is Not Presumptive: Hepatitis C

Hepatitis C does not appear on any VA presumptive list for Korean War veterans. It can still be claimed through direct service connection. The VA has recognized jet gun (air gun) inoculations, used from the 1950s through 1997, as a possible route of blood-borne transmission because the devices were not sterilized between uses. A June 2004 VBA Fast Letter acknowledged that risk.¹¹ Each claim still requires a current diagnosis and a medical opinion linking the infection to an in-service event.

Survivor Benefits

Surviving spouses, children, and dependent parents of Korean War veterans may qualify for several forms of VA compensation. Dependency and Indemnity Compensation (DIC) is a tax-free monthly benefit paid to survivors of veterans who died from a service-connected condition or who were rated totally disabled for a specified period before death.¹² The Survivors Pension is a separate needs-based benefit for unremarried surviving spouses and unmarried dependent children of veterans with qualifying wartime service. The VA recognizes the Korean conflict period as June 27, 1950, through January 31, 1955.¹³

Survivors cannot receive both DIC and Survivors Pension at once; the VA pays the higher of the two.¹² Additional benefits may include CHAMPVA health insurance for eligible dependents, burial benefits, and supplemental Aid and Attendance payments for survivors who are housebound or need help with daily activities.¹⁴

Accrued Benefits and Substitution

When a veteran dies with a claim pending, family members may be able to recover what the veteran had earned but not received. Under 38 CFR 3.1000, accrued benefits are payable first to the surviving spouse, then children, then dependent parents, and an application must be filed within one year of death.¹⁵ Since October 2008, an eligible survivor may also substitute for the deceased claimant and continue the pending claim or appeal, though no new issues can be added beyond what the veteran raised. That request also has a one-year deadline.¹⁶

How to File

Korean War veterans file disability compensation claims on VA Form 21-526EZ — online, by mail to the VA Claims Intake Center in Janesville, Wisconsin, in person at a VA regional office, or by fax. Accredited attorneys, claims agents, and Veterans Service Organization representatives can help at no cost. As of February 2026, the VA reported an average processing time of 76.7 days for disability-related claims.¹⁷

Veterans previously denied for a condition that has since been added to a presumptive list — hypertension or MGUS for DMZ herbicide exposure being the recent examples — should file a Supplemental Claim for reconsideration rather than starting over.⁷ Survivors applying for DIC, Survivors Pension, or accrued benefits use VA Form 21P-534EZ.¹³
