Use this guide to prepare and ask informed questions. VA decides claims under its rules; an accredited representative can advise you about your individual situation.
Separate Exposure From The Medical Condition
An Agent Orange claim usually raises two distinct questions: whether qualifying service or other evidence establishes exposure, and whether the claimed condition is connected to that exposure. A presumption can help answer these questions, but each has its own criteria. Having served during the Vietnam era does not, by itself, establish exposure everywhere.
Begin with a two-column worksheet. On one side, list service dates, locations, units, ships, and duties. On the other, list diagnosed conditions and the medical records confirming them. This makes it easier to see whether the missing information concerns service, diagnosis, or a medical connection rather than collecting unrelated documents.
Verify The Exact Place And Dates
VA recognizes multiple service circumstances, including qualifying Vietnam service, certain offshore service, service in or near the Korean DMZ, specified C-123 aircraft duties, and locations added by the PACT Act. Each has boundaries. For instance, the Thailand provision covers any U.S. or Royal Thai military base from January 9, 1962, through June 30, 1976; it is not a rule covering every person who visited Thailand.
Compare your assignment with the official list rather than a simplified map. For a ship, record its name and the relevant dates. For temporary duty, identify the assignment orders or personnel record. When a document is missing, request the service records and explain which period needs clarification.

Use The Exact Diagnosis And Check Its Conditions
VA’s presumptive list includes specific cancers and illnesses, such as prostate cancer, type 2 diabetes, ischemic heart disease, hypertension, and monoclonal gammopathy of undetermined significance. Those examples do not mean that every cancer, every type of diabetes, or every heart problem is presumptive. Use the diagnosis documented by your treating clinician.
Some conditions have additional timing requirements. Chloracne or a similar acneform disease, early-onset peripheral neuropathy, and porphyria cutanea tarda must meet the specified 10% level within one year of herbicide exposure for that presumption. A diagnosis years later should prompt review of earlier manifestations and other possible service-connection paths, not invented onset dates.
Assemble Records That Answer The Missing Question
Start with separation documents and relevant personnel records. Add the medical report that identifies the condition, its history, and its current effects. A medication list alone may leave the precise diagnosis unclear. If a specialist clarified the condition, include that report and identify any earlier records using a different name.
For a condition outside the presumptive list, medical or scientific evidence connecting it to exposure may be necessary. An article about a broad risk is different from evidence addressing your own diagnosis and circumstances. Discuss that distinction with your clinician or accredited representative instead of assuming a study settles the claim.
- Make an index naming each record, its date, and the fact it supports.
- Identify missing service periods and the office or custodian holding the records.
- Keep copies of submitted records and any authorizations for VA to obtain them.

Check Earlier Decisions Before Filing Again
If VA denied the same condition before, read the reason and date first. A Supplemental Claim can address a new presumption or new and relevant evidence. Do not assume that a new law automatically corrects every old denial or that every award will start on the date of an earlier application.
VA describes special review and retroactive-payment situations for certain Agent Orange claims. Those rules depend on the condition, claim history, and governing law. Bring all earlier decisions and applications to your representative, including denials that used an older diagnosis. Ask which issue needs review, which form applies, and which date rules may matter before submitting duplicate claims.

Keep Health Care And Claim Work Moving Separately
An Agent Orange Registry health exam can help identify concerns and guide follow-up care. It is not a compensation examination, does not confirm exposure for a benefits award, and is not required to receive other VA benefits. A registry appointment also does not replace filing a disability claim.
Schedule needed medical follow-up while the benefits evidence is being assembled. Tell providers about relevant service history without asking them to adopt a diagnosis or conclusion they cannot support. For claim assistance, use VA’s accredited-representative search; accredited VSO representation is free. Take your service worksheet, medical index, and earlier decision letters so the first discussion can focus on the unresolved facts.

Common Questions
Do I Need To Prove I Personally Handled Agent Orange?
Not when a qualifying presumption establishes exposure. You still need evidence of the required service and condition. Outside presumptive circumstances, explain the actual exposure facts and the available supporting evidence rather than assuming era alone is enough.
Does Every Agent Orange Award Include Back Pay To My First Claim?
No. Effective dates and special retroactive rules depend on the history and applicable law. Preserve old decisions and filing receipts so an accredited representative can assess the date issue without promising a particular award.
