Agent Orange presumptive conditions: the full list and who qualifies
If you served where Agent Orange was used, the VA presumes certain illnesses are service-connected, so you don't need a nexus letter. Here's the current condition list, the qualifying locations and dates, and how to file.
Agent Orange was a herbicide the U.S. military used to clear vegetation during the Vietnam era. Veterans exposed to it can develop certain illnesses years or decades later. For a defined list of these conditions, the VA presumes they were caused by the exposure, so an eligible veteran does not have to prove a medical nexus between their service and the diagnosis.
What a presumptive condition means for your claim
Most claims require three things: a current diagnosis, an in-service event or exposure, and a medical opinion linking them. When a condition is presumptive, the VA concedes the exposure and the link, so you generally only need to show two things: that you have the diagnosed condition, and that you had qualifying service. That removes the hardest and most expensive part of the claim, which is obtaining a private nexus opinion.
Conditions the VA presumes are linked to Agent Orange
The presumptive list includes Type 2 diabetes, ischemic heart disease, Parkinson's disease, several cancers (including prostate cancer, respiratory cancers, and some soft-tissue sarcomas and lymphomas), peripheral neuropathy, and others. The PACT Act of 2022 added high blood pressure (hypertension) and monoclonal gammopathy of undetermined significance (MGUS) to the Agent Orange list. The VA maintains the authoritative, current list, so confirm your specific diagnosis against it.
Who qualifies: locations and dates
Presumptive eligibility depends on serving in a recognized time and place. This includes boots-on-the-ground service in the Republic of Vietnam and its inland waterways, and the PACT Act expanded recognized locations to include additional areas such as Thailand, Laos, Cambodia, Guam, American Samoa, and Johnston Atoll for specified periods. Service aboard certain ships and at the Korean Demilitarized Zone in defined windows can also qualify. Check the official VA eligibility page for the exact locations and dates that apply to you.
How to file, and why timing matters
If you have a diagnosed condition on the list and qualifying service, you may be able to file, or re-file even after a prior denial. Submitting an Intent to File first locks in your effective date and can protect up to a year of retroactive back pay while you gather your records. A free, VA-accredited Veterans Service Officer can file the claim with you at no cost.
