Agent Orange Today: Who Is Still Missing Out, and What the Presumptive List Now Covers

Agent Orange is the oldest toxic exposure fight VA has, and it is still producing new grants every month — partly because the presumptive list has grown, and partly because a very large number of eligible veterans concluded decades ago that the door was closed.

Let me be precise about what has changed, because this is an area where secondhand information runs wild.

What actually changed, and when

Two statutes did the heavy lifting.

The Blue Water Navy Vietnam Veterans Act of 2019

Restored the presumption of herbicide exposure to veterans who served in the offshore waters of Vietnam, within 12 nautical miles seaward of the demarcation line of the waters of Vietnam and Cambodia, between January 9, 1962 and May 7, 1975. Before that Act, VA had limited the presumption to those with boots on the ground or service on inland waterways, which excluded enormous numbers of sailors who had been anchored off the coast breathing the same air and distilling the same water.

The PACT Act of 2022

Public Law 117-168 added two conditions to the Agent Orange presumptive list:

• Hypertension
• Monoclonal gammopathy of undetermined significance (MGUS)

and added new locations to the herbicide exposure presumption:

• Thailand at any US or Royal Thai base, January 9, 1962 through June 30, 1976
• Laos, December 1, 1965 through September 30, 1969
• Cambodia at Mimot or Krek, Kampong Cham Province, April 16, 1969 through April 30, 1969
• Guam or 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

One correction while we are here: there has been no new expansion of the Agent Orange list since the PACT Act. VA continues to review conditions and can add more, and you should watch for that — but if someone tells you the list "just expanded again," ask them for the citation. Hypertension being on the list is news to a great many veterans precisely because it arrived in 2022 and nobody told them.

The hypertension point deserves its own paragraph

Hypertension is extraordinarily common among Vietnam-era veterans, and it has been treated for decades as a normal consequence of aging. Since the PACT Act it is a presumptive condition for herbicide-exposed veterans.

That means a veteran who served in Vietnam and has been on blood pressure medication since 1994 has, on the face of it, a presumptive service-connected condition — and has had one since 2022. Many of these veterans have never filed because nobody ever suggested that their blood pressure was a VA matter.

If you are in that group, or you are the surviving spouse of someone who was, this is the paragraph to act on.

The current presumptive condition list

For veterans with presumed or proven herbicide exposure:

• AL amyloidosis
• Bladder cancer
• Chloracne or other acneform disease consistent with chloracne
• Chronic B-cell leukemias, including hairy cell leukemia
• Diabetes mellitus type 2
• High blood pressure (hypertension)
• Hodgkin's disease
• Hypothyroidism
• Ischemic heart disease
• Monoclonal gammopathy of undetermined significance (MGUS)
• Multiple myeloma
• Non-Hodgkin's lymphoma
• Parkinson's disease and parkinsonism
• Peripheral neuropathy, early onset
• Porphyria cutanea tarda
• Prostate cancer
• Respiratory cancers, including lung, bronchus, larynx and trachea
• Soft tissue sarcomas, with certain exceptions

Separately, certain birth defects in children of exposed veterans — spina bifida in the children of veterans who served in Vietnam or Thailand, and a broader list for children of women who served in Vietnam — carry their own benefits. Families almost never know about this one.

Where exposure is presumed

• Vietnam, including inland waterways, January 9, 1962 to May 7, 1975
• Offshore waters of Vietnam within 12 nautical miles, same dates — the Blue Water Navy provision
• The Korean Demilitarized Zone, September 1, 1967 to August 31, 1971
• Thailand at US or Royal Thai bases, January 9, 1962 to June 30, 1976
• Laos, December 1, 1965 to September 30, 1969
• Cambodia at Mimot or Krek, April 16 to April 30, 1969
• Guam, American Samoa and territorial waters, January 9, 1962 to July 31, 1980
• Johnston Atoll or a ship that called there, January 1, 1972 to September 30, 1977

Outside those, exposure can still be proven rather than presumed — herbicide testing, storage, and disposal happened at a number of stateside and overseas locations, and veterans who handled, sprayed, or maintained equipment that used herbicides can establish exposure directly with records.

Who is still missing out

1. Veterans with hypertension who never connected it to service

Covered above. This is the largest group by a wide margin.

2. Blue Water Navy veterans denied before 2019

If you were denied on the basis that you never set foot in Vietnam, and your ship operated within 12 nautical miles, that denial rested on a rule that no longer exists. A Supplemental Claim (VA Form 20-0995) is the route, and deck logs and ship histories are the evidence.

3. Thailand veterans

Air Force security police, dog handlers, and anyone who worked the perimeter at Thai bases had a hard road for years, with VA often requiring proof of duty near the base perimeter. The PACT Act's Thailand provision changed the landscape. If you were denied under the old approach, look again.

4. Korean DMZ veterans

The DMZ presumption is well established and still widely unknown. Service in that window, in that place, is covered.

5. Survivors

This is the one that costs families the most. If a veteran died of a condition now on the presumptive list — or was rated totally disabled for the required period before death — the surviving spouse may be eligible for Dependency and Indemnity Compensation. Widows are filing successfully on deaths that occurred years ago. Nobody from VA is going to call and tell them.

6. Veterans who assume it is too late

There is no deadline to file a disability claim. A denial from 1998 does not bar a new claim today, and if the law changed in the interim, a supplemental claim is the correct tool.

What to do

1. File an Intent to File. Locks your effective date for up to 12 months while you gather documents.
2. Check the list against your medication cabinet. Blood pressure medication, thyroid medication, diabetes medication — those map directly onto three presumptive conditions.
3. Establish where you were. DD-214, orders, deck logs, unit histories, award citations. For Blue Water Navy, the ship's location on specific dates is the whole case.
4. Get severity measured. A presumption gets you service connection. Numbers get you a percentage — blood pressure readings over time, echocardiogram results, A1C values, neurological testing.
5. Read old denials. Especially anything decided before 2019 or before 2022.
6. If a veteran in your family died of something on that list, look into DIC. Do not assume the window closed.

The summary

Agent Orange claims are, by VA standards, some of the most straightforward available — the exposure presumption is decades old and well litigated, and the condition list is published. The failure is almost entirely one of awareness.

Hypertension has been presumptive since 2022. Offshore Navy service has been covered since 2019. Thailand, Laos, Guam and Johnston Atoll are all in the regulation. If any of that is news to you, you are exactly the person this article is for.
