Agent Orange presumptive service connection is a rule under 38 U.S.C. 1116 that spares eligible veterans from having to prove their illness was caused by military service. If you served in a location the VA has designated as one where herbicide exposure occurred, and you have been diagnosed with a disease on the VA’s presumptive list, the VA presumes the connection and you qualify for disability compensation. Two boxes to check: covered service, and a covered condition.
Covered Service Locations and Dates
The statute lists the places and periods that trigger the presumption. Service anywhere in the following counts as “covered service” under 38 U.S.C. 1116(d):
- Republic of Vietnam, January 9, 1962 through May 7, 1975, including inland waterways.
- Offshore waters of Vietnam within 12 nautical miles of the coast during the same period, added by the Blue Water Navy Vietnam Veterans Act of 2019.
- Any U.S. or Royal Thai military base in Thailand, January 9, 1962 through June 30, 1976. The PACT Act removed earlier limits that had restricted this to veterans working near the base perimeter.
- Laos, December 1, 1965 through September 30, 1969.
- Mimot or Krek, Kampong Cham Province, Cambodia, April 16 through April 30, 1969.
- Guam, American Samoa, or their territorial waters, January 9, 1962 through July 31, 1980.
- Johnston Atoll, or a ship that called there, January 1, 1972 through September 30, 1977.
The Thailand, Laos, Cambodia, Guam, American Samoa, and Johnston Atoll categories were added by the Sergeant First Class Heath Robinson Honoring Our Promise to Address Comprehensive Toxics (PACT) Act of 2022.1Office of the Law Revision Counsel. 38 USC 1116 – Presumptions of Service Connection for Diseases Associated With Exposure to Certain Herbicide Agents
A separate regulation, 38 C.F.R. 3.307(a)(6)(iv), presumes exposure for veterans whose unit operated in or near the Korean Demilitarized Zone between April 1, 1968 and August 31, 1971, as determined by the Department of Defense.2eCFR. 38 CFR 3.307 – Presumptive Service Connection for Chronic Diseases The VA’s Agent Orange Registry recognizes Korean DMZ service back to September 1, 1967 for administrative purposes.3Department of Veterans Affairs. Agent Orange Registry Health Exam for Veterans
Veterans who flew on or worked with C-123 aircraft previously used in Operation Ranch Hand between 1969 and 1986 may also qualify, along with veterans exposed during testing, transport, or spraying at other military installations. These cases usually need additional documentation because the presumption is not automatic in the same way it is for a Vietnam veteran with service records.
Diseases on the Presumptive List
If you have covered service and one of the diagnoses below, the VA presumes herbicide exposure caused it. No independent medical opinion linking your illness to your service is required.
- Cancers: bladder cancer, Hodgkin’s disease, non-Hodgkin’s lymphoma, multiple myeloma, prostate cancer, respiratory cancers (lung, bronchus, larynx, or trachea), and soft tissue sarcomas (excluding osteosarcoma, chondrosarcoma, Kaposi’s sarcoma, and mesothelioma).
- Blood disorders: AL amyloidosis, chronic B-cell leukemias (including chronic lymphocytic leukemia), monoclonal gammopathy of undetermined significance (MGUS), and other myelodysplastic syndromes.
- Cardiovascular and metabolic: ischemic heart disease, hypertension, and type 2 diabetes mellitus.
- Neurological: Parkinson’s disease, Parkinsonism, and early-onset peripheral neuropathy.
- Other: chloracne or a similar acneform disease, hypothyroidism, and porphyria cutanea tarda.
Three conditions have onset deadlines. Chloracne and porphyria cutanea tarda must become at least 10 percent disabling within one year of your last date of covered service. Early-onset peripheral neuropathy must reach 10 percent disability within one year of exposure.1Office of the Law Revision Counsel. 38 USC 1116 – Presumptions of Service Connection for Diseases Associated With Exposure to Certain Herbicide Agents The rest of the list has no onset deadline.
The list keeps growing. The National Defense Authorization Act for Fiscal Year 2021 added bladder cancer, hypothyroidism, and Parkinsonism. The PACT Act added hypertension and MGUS.4Department of Veterans Affairs. Agent Orange Newsletter – 2025 The VA relies on reports from the National Academy of Sciences, Engineering, and Medicine when evaluating new candidates.
If Your Condition Isn’t on the List
A condition off the list is not a dead end. It just means the VA won’t presume the connection, so you build one. Three pieces of evidence are needed: a current diagnosis, proof of in-service herbicide exposure, and a medical nexus opinion from a qualified physician stating that your condition is at least as likely as not linked to that exposure. Private nexus letters from independent doctors typically run $500 to $4,000 depending on complexity and specialty.
There’s also secondary service connection. If a condition already service-connected to Agent Orange has caused or worsened another condition, that second condition can be service-connected too. A veteran already compensated for type 2 diabetes who then develops kidney disease or peripheral neuropathy as a complication is the common example. You still need a doctor’s opinion tying the secondary condition to the primary one, but you don’t have to prove direct herbicide causation for the secondary condition.5U.S. Department of Veterans Affairs. Agent Orange Exposure and Disability Compensation
How to File
Claims are filed on VA Form 21-526EZ, the standard application for service-connected disability benefits.6Veterans Affairs. About VA Form 21-526EZ You can submit it online at VA.gov, by mail, or in person at a VA regional office. Accredited Veterans Service Organizations help at no cost; attorneys and claims agents may charge regulated fees.
For a presumptive claim, the evidence is usually simple: service records showing you were in a covered location during a covered period, and medical records confirming your diagnosis. Vietnam and offshore-waters service during the covered period generally satisfies the exposure element on its own.
For locations where documentation is thinner, such as certain Thailand bases before the PACT Act expansion or installations involved in herbicide testing, unit histories, declassified reports, and sworn statements from fellow service members can help. The VA’s Compensation and Pension Service maintains records of locations where herbicides were tested or stored. The overall standard is generous: under 38 U.S.C. 5107, when evidence for and against the claim is roughly equal, the benefit of the doubt goes to the veteran.7Office of the Law Revision Counsel. 38 USC 5107 – Claimant Responsibility; Benefit of the Doubt
Most claims trigger a Compensation and Pension (C&P) examination with a VA-appointed clinician, whose report heavily influences the rating.
What the Compensation Looks Like
The VA assigns disability ratings from 0 to 100 percent in 10-point increments. A 0 percent rating still establishes service connection, which can matter later if the condition worsens or produces secondary conditions. For 2026, monthly compensation for a veteran with no dependents runs from $180.42 at 10 percent to $3,938.58 at 100 percent.8Veterans Affairs. Current Veterans Disability Compensation Rates
- 10%: $180.42 per month
- 30%: $552.47 per month
- 50%: $1,132.90 per month
- 70%: $1,808.45 per month
- 100%: $3,938.58 per month
Veterans rated at 30 percent or higher receive additional compensation for dependents. Multiple service-connected conditions are combined under a formula in 38 CFR Part 4 rather than simply added.9eCFR. 38 CFR Part 4 – Schedule for Rating Disabilities
Retroactive Pay Under the Nehmer Rules
Agent Orange claims can carry effective dates far earlier than the day you file, thanks to the Nehmer v. U.S. Department of Veterans Affairs class action settlement. When a condition is added to the presumptive list, veterans who previously filed for that condition and were denied, or whose claims were pending, may have their effective date pushed back to the original claim date or the date the disability arose, whichever is later. This applies to claims denied between September 25, 1985 and May 3, 1989, claims pending on May 3, 1989, and claims filed between that date and the date the presumption was established.10eCFR. 38 CFR 3.816 – Awards Under the Nehmer Court Orders
If you filed within one year of separating from service, the effective date can reach back to the day after discharge. For conditions added to the list decades after service, the resulting retroactive payments can be substantial.
If Your Claim Is Denied
The Veterans Appeals Improvement and Modernization Act of 2017 gives you three ways to challenge a denial:11U.S. Senate. Veterans Appeals Improvement and Modernization Act of 2017
- A supplemental claim, where you submit new and relevant evidence. Good when new medical research, a fresh nexus letter, or a newly added presumptive condition strengthens the case.
- A higher-level review, where a more senior VA adjudicator re-examines the existing file. Use it when you believe the law was misapplied or evidence was overlooked. Request within one year of the decision.12Veterans Affairs. Higher-Level Reviews
- An appeal to the Board of Veterans’ Appeals, where a Veterans Law Judge reviews the case and you can request a hearing. Slower but more thorough.
Beyond the Board, the U.S. Court of Appeals for Veterans Claims provides judicial review. Filing within one year of a denial preserves your original effective date, which can be worth a lot in retroactive pay.
Benefits for Survivors and Children
When a veteran dies from an Agent Orange–connected condition, a surviving spouse or dependents may qualify for Dependency and Indemnity Compensation (DIC). The base monthly DIC payment for a surviving spouse in 2026 is $1,699.36, with additions for dependents, Aid and Attendance, or housebound status.13Veterans Affairs. Current DIC Rates for Spouses and Dependents A surviving spouse must generally have lived with the veteran until death, and must have either married the veteran within 15 years of discharge from the qualifying service, been married at least one year, or had a child with the veteran.14Veterans Affairs. About VA DIC for Spouses, Dependents, and Parents Remarriage at age 55 or older on or after January 5, 2021 does not disqualify a surviving spouse.
If a claim was pending when the veteran died, a surviving spouse or child can continue it through substitution. Survivors can also seek accrued benefits on VA Form 21P-534EZ.15Veterans Affairs. Accrued Benefits
Biological children of veterans who served in Vietnam, Thailand, or near the Korean DMZ during covered periods may qualify for benefits if born with spina bifida (other than spina bifida occulta).16Veterans Affairs. Benefits for Spina Bifida Linked to Agent Orange The 2026 monthly amounts:17Veterans Affairs. 2026 Birth Defect Compensation Rates
- Level I (least disabling): $430 per month
- Level II: $1,457 per month
- Level III (most disabling): $2,479 per month
Children of female Vietnam veterans have a broader list of covered birth defects, including cleft lip and palate, congenital heart disease, hip dysplasia, hydrocephalus, and neural tube defects. Conditions caused by hereditary genetic disorders, chromosomal abnormalities, birth-related injury, or fetal infirmity with well-established causes are excluded.18Federal Register. Monetary Allowances for Certain Children of Vietnam Veterans – Identification of Covered Birth Defects Eligible children can receive monthly compensation, VA health care, and vocational training benefits.
