Vietnam Era · 38 CFR §3.309(e)
Agent Orange & Herbicide Claims
The military sprayed roughly 20 million gallons of herbicides, Agent Orange chief among them, across Vietnam and other theaters. The dioxin in it does not leave the body quickly, and the diseases it causes can surface decades later.
Agent Orange presumptives are among the strongest in the entire VA system. If you set foot in a covered location during the covered window and carry a listed diagnosis, service connection is presumed, and a single grant can unlock an entire chain of secondary conditions.
Agent Orange / Herbicides at a Glance
These numbers show the scale of the problem, not the strength of your individual claim. The VA does not grant claims because a lot of veterans were exposed. It grants them when your file shows you were in the right place at the right time and you carry a current diagnosis. Use these figures as context, then move down the page and check your own service dates, locations, and medical records against each step.
20M

Qualifying Service Locations
Your service location and dates are what trigger the exposure concession. Find where your service fits below, then make sure the record proves it. The VA will not take your word for it. Your DD-214, deployment orders, unit records, or personnel file have to place you in the location during the covered dates. Your part is to pull those documents before you file. If your orders are missing or vague, buddy statements and unit histories can fill the gap, but they take time to gather, so start now.
Vietnam
In-country service, service in the inland waterways, offshore "blue water" service, or service in the airspace above, January 9, 1962 to May 7, 1975.
Thailand
Royal Thai Air Force bases (U-Tapao, Ubon, Nakhon Phanom, Udorn, Takhli, Korat, Don Muang) near the base perimeter, January 9, 1962 to June 30, 1976.
Korea DMZ
Units operating in or near the Korean Demilitarized Zone, September 1, 1967 to August 31, 1971.
C-123 aircraft & test/storage sites
Crews who flew or maintained contaminated C-123 aircraft after Vietnam, plus recognized herbicide test and storage sites in the U.S. and abroad.
Covered Conditions
If you carry one of these diagnoses and your service matches the locations above, you are on the shortest path to service connection. The presumption covers causation, not the diagnosis. You still need a doctor to put the condition in writing, by name, in your medical records. A note that says "breathing problems" is not the same as a diagnosis of asthma or COPD. Check your records for the exact term, and if it is missing, ask your provider to document it before you file.
The PACT Act added bladder cancer, hypertension, hypothyroidism, MGUS, and parkinsonism to this list. If you were previously denied for one of these conditions, file a Supplemental Claim, the new law is your "new and relevant evidence."
The Evidence You Need
A clean, complete file is the difference between a grant and a denial. Here is what belongs in yours. Under 38 CFR 3.159 the VA has a duty to help you gather records, but it only goes after what you tell it exists. Your part is to identify every provider, sign the release forms, and send what you already have. A file that arrives complete gets decided faster and gives the rater less room to deny.
DD-214 & unit records
Show service in a covered location and window. For Thailand and Korea, unit and duty-station records establishing perimeter proximity matter.
Current diagnosis
A current diagnosis of a listed condition. The presumption handles causation once location is established.
Secondary condition map
Identify conditions that flow from the primary grant, these are separately compensable and often missed.
Blue water Navy evidence
Ship deck logs, cruise books, or buddy statements showing the vessel operated in Vietnamese territorial waters or inland waterways.
Thailand perimeter evidence
Duty records, performance reports, or buddy statements placing you on the perimeter of a covered RTAF base during the spray window.
Death & survivor records
For DIC claims, records tying the veteran's death to a presumptive condition.
How This Claim Is Won
A grant of Agent Orange-presumptive Type 2 diabetes is a doorway, not a destination. Diabetes causes peripheral neuropathy, retinopathy, kidney disease, erectile dysfunction, and contributes to hypertension, each of which is separately ratable as a secondary condition under 38 CFR §3.310.
If you served in Thailand or on the Korea DMZ and were told you "weren't in Vietnam so you don't qualify," that is wrong. The covered locations extend well beyond Vietnam, the file simply has to prove where you were.
The secondary-condition chain from Agent Orange presumptives is the most powerful combined-rating strategy in the VA system. A single diabetes grant can drive a combined rating from 20% to 80% or higher through peripheral neuropathy alone, before counting retinopathy, kidney disease, and ED.
Bottom line: an accredited records review confirms which pathway fits your file and makes the file say it out loud, before the VA decides for you.
Advice from the Advocate
The Presumption Does the Heavy Lifting
Here is the good news, and it is rare in this system. If you served in a covered location during the covered window and you carry a listed diagnosis, the law presumes Agent Orange caused it. No doctor has to connect the dots. Nobody has to prove you were sprayed. The VA has to concede it.
So why do so many of these claims still get denied? Because veterans lose on the parts nobody warned them about, proof of where you served and the conditions you never claimed. Thailand, the Korea DMZ, blue water, and C-123 service all qualify, but only if your file shows it. And one diabetes grant opens a chain of secondary conditions the VA will not add for you. Shocking, I know.
The Advocate’s Take
Agent Orange presumptives are the strongest claims in the VA system, and I fight them that way. But strong is not the same as automatic. The presumption only works once your file proves you were there. Until then, you are just another veteran with a diagnosis and a story, and the VA does not pay stories.
Here is how the VA looks at it. Under 38 CFR 3.307(a)(6) and 3.309(e), if you served in a covered location during a covered window and you carry a listed condition, exposure is conceded and the link is presumed. No nexus letter required. That covers Vietnam, the offshore waters under the Blue Water Navy Act, the Korea DMZ, qualifying Thailand bases, Laos, Cambodia, Guam, American Samoa, Johnston Atoll, and the C-123 aircraft. The PACT Act added hypertension and MGUS to the list. This is a presumption lane, and it is completely separate from a TERA exam request. Do not let anyone blur the two.
What I need from you is simple, and it matters more than anything else. Your DD-214, your personnel file, your ship or unit, and your dates. Deck logs if you were Navy. Base names and duties if you were in Thailand, because perimeter work is what gets those claims granted. Then your diagnosis from a doctor, in writing. If you have a buddy who can put you on that base or that ship, a signed 21-10210 statement is gold.
Walk through it with me. First, we file an Intent to File, VA Form 21-0966, so your effective date is locked while we build. Second, I prove your location. Third, we win the primary condition, usually diabetes, heart disease, or a listed cancer. Fourth, and this is where the money hides, I go after every secondary condition that flows from it under 38 CFR 3.310: the neuropathy in your hands and feet, the retinopathy, the kidney disease, the erectile dysfunction and the SMC(k) that comes with it. The VA will not add those for you. Shocking, I know.
The pitfalls are predictable. Veterans claim the diagnosis and forget the location proof. They accept a 20% diabetes rating without showing the regulation of activities their doctor ordered. They skip the secondaries because nobody told them they existed. And they quit when someone at a VSO said, "You were never in Vietnam, so you do not qualify." That answer is wrong until your records say otherwise.
Your part: pull your records, write down every base and ship with dates, get your diagnoses on paper, and tell me every symptom, not just the big one. If you were denied years ago for a listed condition, tell me that too, because Nehmer may reach back to your original claim date. We work WITH you, not FOR you. Bring me the pieces, and I will put them together in the order the VA has to follow.
Getting connected is only half the fight. The C&P exam decides how much you are paid. It is where your diabetes management, your nerve damage, and your heart function get measured, and where a rushed examiner quietly costs you rating levels. Watch the official VA videos below so you know what a proper exam looks like, then hold the VA to it.

What the VA’s own guidance covers, what to bring, how to report your symptoms honestly, and the mistakes that cost veterans rating levels.
Secondary Condition Chains
Under 38 CFR §3.310, a service-connected condition that causes or aggravates another condition makes that second condition service-connected too, each rated on its own. This is where most veterans leave money on the table. They file for the primary condition and stop. The VA will not go looking for the secondaries for you. Each one needs a current diagnosis and a medical opinion that ties it to the primary, either as the cause or as the thing that made it worse. Read the chains below and ask your doctor about every one that fits.
| Primary (Service-Connected) | Secondary It Can Cause | Rating Impact |
|---|---|---|
| Type 2 Diabetes | Peripheral neuropathy, all 4 extremities | Each extremity rated separately, the combined value frequently exceeds the diabetes rating alone |
| Type 2 Diabetes | Diabetic retinopathy | Rated on visual impairment; can be a separately compensable high-value claim |
| Type 2 Diabetes | Chronic kidney disease / nephropathy | Rated on renal function, frequently a high-value secondary |
| Type 2 Diabetes | Erectile dysfunction | Often 0% schedular but qualifies for Special Monthly Compensation (SMC-k) |
| Ischemic heart disease | Secondary anxiety / depression | Mental health rating under §4.130, common and often missed |
| Parkinson's disease | Speech/swallowing difficulty, tremor, gait impairment | Multiple ratable symptoms, each documented separately for maximum combined rating |

Rating Information
Understanding how the VA rates agent orange / herbicides conditions helps you document the evidence that drives a higher rating. Service connection only gets you in the door. The percentage is set by the criteria in 38 CFR Part 4, and those criteria turn on specific test results, symptoms, and treatment records. If the exam misses something, the rating comes in low. Bring your own records to the exam, describe your worst days honestly, and check the decision against the criteria below.
Diabetes rating depends on management
Type 2 diabetes is rated on how much management it requires, diet only, oral medication, insulin, and whether it causes regulation problems. Each level of management corresponds to a higher rating bracket. Document your treatment regimen thoroughly.
Peripheral neuropathy, each limb counts
Each extremity with diabetic neuropathy is rated separately under the peripheral nerve codes. The key evidence is nerve conduction studies (NCS) and EMG results documenting the type and severity of involvement in each limb.
Ischemic heart disease, METs and ejection fraction
Heart disease is rated primarily by METs (metabolic equivalents) capacity and left ventricular ejection fraction. A cardiac stress test and echocardiogram are the critical pieces of evidence.
SMC(k) for loss of use
Erectile dysfunction from diabetes qualifies for Special Monthly Compensation at the (k) rate, a monthly payment on top of the regular compensation. It does not require a high schedular rating for ED itself.
Exact percentages depend on the diagnostic code and severity documented in your records. These notes describe what factors drive the rating, not guaranteed outcomes.
Questions Veterans Ask
These are the questions veterans ask me most about Agent Orange / Herbicides claims. The answers are short on purpose, so you can find yours fast. Your part is to check each one against your own service dates, locations, and diagnosis, and bring anything that does not fit to a records review.
I was "blue water" Navy offshore, am I covered now?
Yes. The Blue Water Navy Vietnam Veterans Act extended the herbicide presumption to veterans who served in the offshore waters of Vietnam. If you were previously denied as "blue water," that denial should be revisited with a Supplemental Claim.
How can diabetes be "worth" more than its own rating?
Because of the secondary chain. Diabetes rated at 20–40% can carry secondary peripheral neuropathy in all four extremities, retinopathy, kidney involvement, and erectile dysfunction, each rated on its own. The combined value routinely exceeds the diabetes rating alone.
My father died of a presumptive cancer years ago. Can we still file?
Possibly. Surviving spouses and dependents may be eligible for DIC and accrued benefits if the veteran died of a now-presumptive condition. These survivor claims are frequently overlooked and are worth a review.
I served in Thailand but was told I don't qualify. Is that right?
Not necessarily. Herbicide exposure is conceded for veterans who served at or near the perimeter of covered Royal Thai Air Force Bases during the spray window. Duty records, unit histories, and buddy statements can establish perimeter duties even when the DD-214 does not spell it out.
I have hypertension, is that now presumptive?
Yes. The PACT Act added hypertension to the Agent Orange presumptive list. If you served in a covered location and have a current hypertension diagnosis, you likely qualify. If you were previously denied, file a Supplemental Claim citing the PACT Act as new evidence.
Can I get back pay if my condition was just added to the list?
If you file within one year of the condition's effective date on the presumptive list, your effective date can reach back to August 10, 2022 (the PACT Act signing date). Earlier filing = more back pay. File an Intent to File today to lock in your date.
Related Pathways & Services
Toxic exposure claims rarely stand alone. A presumptive grant often opens the door to secondary conditions, a higher combined rating, TDIU, or survivor benefits down the road. If you have already been denied, the appeal lane you choose matters as much as the evidence. The pages below walk through each of those next steps so you can see the whole picture before you decide what to file.
