Decades later, Agent Orange is still generating claims. If you served where it was used, the presumptions may already be in your favor.
Agent Orange did not stop causing claims when the war ended. Conditions tied to that herbicide are still surfacing in Vietnam veterans today, and the law presumes many of them are service-connected.
The presumptive list
For veterans with qualifying Vietnam-era service, the VA presumes service connection for conditions including ischemic heart disease, Parkinson's disease, several cancers, and type 2 diabetes, among others. You do not have to prove the herbicide caused it, the law already does.
Where you served matters
Boots-on-ground service in Vietnam, service in the offshore waters (Blue Water Navy), and certain other locations can all trigger the presumption. We reconstruct unit records and locations when the VA claims your service does not qualify.
If you were denied years ago under a narrower rule, the door may be open again. Do not let an old denial be the end of the story.
The regulatory authority behind toxic-exposure claims lives in M21-1, Part IV, Subpart ii, Chapter 2, Section C (Service Connection for Disabilities Resulting from Exposure to Environmental Hazards). This section governs how raters develop and adjudicate toxic-exposure claims, including burn-pit, Agent Orange, contaminated-water, and radiation claims, and cross-references the PACT Act's conceded-exposure framework under 38 U.S.C. §1168 (TERA). When a C&P examiner renders a negative nexus opinion without addressing the documented exposure pathway, that opinion is inadequate under Barr v. Nicholson, and raters are required to return it for a supplemental opinion. Veterans who receive a denial after a cursory exam should cite the specific M21-1 development procedures the rater failed to follow.
