Title 38 United States Code 501(a), 1116(a)(3), and 1821)

Here is the basis for Agent Orange claims of Vietnam veterans, Korea DMZ veterans, and C-123 veterans. These are the three groups considered "presumptively exposed" as described in Title 38 United States Code 501(a), 1116(a)(3), and 1821.) C-123 veterans join the others as the only groups covered by VA's automatic presumption of exposure and coverage for illnesses recognized by VA as associated with Agent Orange.

I recommend veterans beginning the claims process include the VA C-123 Fact Sheet and the Title 38 USC C-123 page when you meet with VA or veterans service organizations – this is a new topic for everyone and very few understand our entitlements.

(6) Diseases associated with exposure to certain herbicide agents. (i) For the purposes of this section, the term “herbicide agent” means a chemical in an herbicide used in support of the United States and allied military operations in the Republic of Vietnam during the period beginning on January 9, 1962, and ending on May 7, 1975, specifically: 2,4-D; 2,4,5-T and its contaminant TCDD; cacodylic acid; and picloram.(Authority: 38 U.S.C. 1116(a)(4))(ii) The diseases listed at §3.309(e) shall have become manifest to a degree of 10 percent or more at any time after service, except that chloracne or other disease consistent with chloracne, porphyria cutanea tarda, and early-onset peripheral neuropathy shall have become manifest to a degree of 10 percent or more within a year after the last date on which the veteran was exposed to an herbicide agent during active military, naval, or air service.(iii) A veteran who, during active military, naval, or air service, served in the Republic of Vietnam during the period beginning on January 9, 1962, and ending on May 7, 1975, shall be presumed to have been exposed during such service to an herbicide agent, unless there is affirmative evidence to establish that the veteran was not exposed to any such agent during that service. The last date on which such a veteran shall be presumed to have been exposed to an herbicide agent shall be the last date on which he or she served in the Republic of Vietnam during the period beginning on January 9, 1962, and ending on May 7, 1975. “Service in the Republic of Vietnam” includes service in the waters offshore and service in other locations if the conditions of service involved duty or visitation in the Republic of Vietnam.(iv) A veteran who, during active military, naval, or air service, served between April 1, 1968, and August 31, 1971, in a unit that, as determined by the Department of Defense, operated in or near the Korean DMZ in an area in which herbicides are known to have been applied during that period, shall be presumed to have been exposed during such service to an herbicide agent, unless there is affirmative evidence to establish that the veteran was not exposed to any such agent during that service. See also 38 CFR 3.814(c)(2).(v) An individual who performed service in the Air Force or Air Force Reserve under circumstances in which the individual concerned regularly and repeatedly operated, maintained, or served onboard C-123 aircraft known to have been used to spray an herbicide agent during the Vietnam era shall be presumed to have been exposed during such service to an herbicide agent. For purposes of this paragraph, “regularly and repeatedly operated, maintained, or served onboard C-123 aircraft” means that the individual was assigned to an Air Force or Air Force Reserve squadron when the squadron was permanently assigned one of the affected aircraft and the individual had an Air Force Specialty Code indicating duties as a flight, ground maintenance, or medical crew member on such aircraft. Such exposure constitutes an injury under 38 U.S.C. 101(24)(B) and (C). If an individual described in this paragraph develops a disease listed in 38 CFR 3.309(e) as specified in paragraph (a)(6)(ii) of this section, it will be presumed that the individual concerned became disabled during that service for purposes of establishing that the individual served in the active military, naval, or air service.(Authority: 38 U.S.C. 501(a), 1116(a)(3), and 1821)
