The VA Agent Orange Registry health exam is a free clinical evaluation for veterans who may have been exposed to Agent Orange or other herbicides during military service. The exam is voluntary, does not require proof of illness, and is separate from filing a VA disability claim.
What the Agent Orange Registry is
The Agent Orange Registry is one of the VA's longest-standing exposure-tracking programs. It exists for two purposes: to give individual veterans a free clinical evaluation and to give VA researchers and clinicians a population-level picture of the long-term health effects of Vietnam-era herbicide exposure.
Enrolment is voluntary. There is no requirement that a veteran already have a diagnosis or a pending claim. The Registry is most often used by Vietnam-era veterans, but eligibility has expanded over the decades and now includes service in Korea, Thailand, and other locations during qualifying periods.
Who qualifies for the exam
Veterans who served in locations and during periods recognised by the VA as involving herbicide exposure are eligible. This includes service in Vietnam between January 9, 1962 and May 7, 1975, certain Korean DMZ service from April 1, 1968 to August 31, 1971, Thailand service during the Vietnam era at qualifying bases, and certain other locations expanded under recent legislation.
The PACT Act broadened the list of qualifying locations to include several additional sites in Thailand, Laos, Cambodia, Guam, American Samoa, and Johnston Atoll, as well as expanded eligibility for veterans involved in storing, testing, or transporting Agent Orange.
How to request the exam
Contact the Environmental Health Coordinator at your local VA medical centre. The coordinator schedules the exam, takes a detailed exposure history, and refers you for any indicated lab work or specialist evaluation. There is no co-pay for the registry exam, regardless of your VA priority group.
You may bring a friend, family member, or VSO representative to the appointment. Bringing your DD-214, deployment records, and a list of any medical conditions or current medications speeds up the intake.
What the exam covers
The exam includes a medical history with detailed military service and exposure history, a physical examination, basic laboratory tests, and any clinically indicated additional tests. The Environmental Health Coordinator focuses on the presumptive conditions associated with herbicide exposure but will also document general health concerns.
After the exam, the coordinator typically provides a written summary of findings and recommendations. This summary becomes a useful piece of evidence if a veteran later files a VA disability claim.
Recognised Agent Orange presumptive conditions
Recognised presumptive conditions include several cancers, soft-tissue sarcomas, certain heart and metabolic conditions, and others. The list has grown substantially over the decades and the PACT Act added further conditions including hypertension and MGUS.
- Ischaemic heart disease
- Type 2 diabetes
- Parkinson's disease and Parkinsonism
- Hypertension (added under the PACT Act)
- Bladder cancer
- Hypothyroidism
- Multiple specific cancers and soft-tissue sarcomas
- MGUS — monoclonal gammopathy of undetermined significance
Does the exam affect my disability claim?
The Registry exam itself is not a VA disability claim. However, exam findings may identify conditions on the Agent Orange presumptive list, which can support a separate compensation claim. The written exam summary, combined with VA records of qualifying service, often forms the backbone of an Agent Orange claim.
Conversely, declining the exam does not prevent a claim. Many veterans file successful Agent Orange claims based purely on their VA primary-care records, civilian medical records, and presumptive eligibility.
After the exam — practical next steps
If the exam identifies a presumptive condition, the most efficient next step is usually to file an Intent to File on VA Form 21-0966 to preserve your effective date, then submit a formal claim on VA Form 21-526EZ. Reference the Registry exam in your claim and attach the written summary if you have a copy.
If the exam identifies a condition that is not on the presumptive list, you may still have a service connection case. In that situation, a nexus letter from a treating physician — explicitly addressing whether the condition is 'at least as likely as not' related to herbicide exposure — can be the deciding piece of evidence.
Care for surviving family members
If a Vietnam-era veteran has passed away from a presumptive condition, surviving spouses and dependants may have eligibility for DIC. The Registry exam history of the deceased veteran is one piece of evidence that can support a DIC claim, alongside the death certificate and any treating-physician records linking cause of death to a presumptive condition.
What to bring to your Agent Orange Registry exam
The exam is a focused review of your service history, current health, and any conditions you suspect are related to herbicide exposure. Bringing the right paperwork shortens the appointment and gives the examiner the context to identify presumptive conditions you may not have flagged yourself.
Many veterans walk into the exam thinking only about the conditions they already know about. The examiner is trained to look across the full Agent Orange presumptive list and may identify conditions you did not realise were covered.
- DD-214 and any documents showing Vietnam, Korea DMZ, Thailand base perimeter, or other qualifying service
- List of current medications and treating providers
- Records of any cancer, diabetes, ischemic heart disease, Parkinson's, or hypertension diagnoses
- Family history of conditions that can be relevant to herbicide-related disease
- Any prior VA decisions on Agent Orange claims, including denials
Common Agent Orange claim mistakes
The single biggest mistake we see is veterans who were denied years ago and never refiled after hypertension and MGUS were added to the presumptive list. Those denials do not refile themselves — the veteran must take action.
A second common mistake is assuming you must prove the exposure event itself. For qualifying service locations and time windows, exposure is presumed; you do not need to document a specific spraying incident.
- Not refiling after the presumptive list expanded to include hypertension
- Trying to prove a specific exposure event when presumption already applies
- Filing the wrong appeal lane after a denial
- Missing surviving-spouse DIC eligibility when a Vietnam-era veteran has died of a presumptive cancer
How Cross & York supports Agent Orange veterans and survivors
Our Agent Orange workflow starts with a presumption check across every condition the veteran has been diagnosed with, then a back-pay analysis if any condition was added to the list after a prior denial. Survivors of Vietnam-era veterans get a parallel DIC review.
Veterans can complete the Agent Orange Registry exam and file claims directly at VA.gov without any cost. A VA-accredited VSO can also help. We are one option among several, and we will say so up front if a free option is a better fit for your case.
Frequently overlooked next steps
The Agent Orange Registry exam and the disability claim are two separate processes. Many veterans complete the exam, learn they have a presumptive condition, and then never file the claim because they assume one triggers the other. It does not — you must file the disability claim yourself or through a representative.
Spouses and adult children of Vietnam-era veterans should also know that certain birth defects are covered under separate benefit programs. If you suspect a connection between a parent's Agent Orange exposure and a child's congenital condition, that is worth raising with a VSO or accredited attorney.
Veterans can file directly at VA.gov or work with a free VSO at any point in this process.
Frequently asked questions
Is the Agent Orange Registry exam free?
Yes. The exam is provided at no cost to qualifying veterans, regardless of priority group.
Do I need to prove I have a condition before requesting the exam?
No. The exam is a screening tool. You can request it whether or not you currently have a diagnosed condition.
Will the exam result automatically file a disability claim?
No. The Registry exam is separate from the disability process. You must file a claim with VA Form 21-526EZ to pursue compensation.
