How to File a PACT Act Claim in 2026: Step-by-Step Guide
The PACT Act (Public Law 117-168) — signed August 10, 2022 — is the single largest expansion of VA benefits in history, covering millions of veterans exposed to burn pits, Agent Orange, radiation, and other toxic substances. But knowing you may qualify is not the same as knowing how to file. The 2026 filing landscape includes presumptive conditions lists, the toxic exposure screening mandate, specific VA Form 21-526EZ sections that must be completed correctly, and the supplemental claim pathway for veterans who were previously denied. This guide walks you through every step so your claim lands correctly the first time.
What the PACT Act Does
The Sergeant First Class Heath Robinson Honoring our Promise to Address Comprehensive Toxics Act of 2022 (PACT Act) fundamentally changed how VA handles toxic exposure claims by:
Establishing presumptive service connection for dozens of conditions linked to burn pit exposure, Agent Orange, and other toxic substances — meaning veterans no longer need to prove their condition was caused by service if they have the exposure history and a qualifying diagnosis
Mandating toxic exposure screening for all veterans during VA primary care visits
Expanding the VA health care eligibility to veterans with hazardous exposure, even those who otherwise wouldn't have enrolled
Requiring VA to automatically review previously denied claims that may now qualify under the new presumptives
Extending the Gulf War period definition and adding new locations to Agent Orange exposure presumption
The law took effect on a rolling basis after August 10, 2022. By 2026, VA has processed millions of PACT Act claims — but many veterans who qualify have still not filed. If you served in a deployed environment after August 2, 1990, or served in Vietnam-era locations, you should review whether the PACT Act applies to your health conditions.
Who Qualifies for PACT Act Claims
Gulf War and Post-9/11 Veterans (Burn Pit Exposure)
Veterans who served in Southwest Asia, Central Asia, or certain other locations after August 2, 1990 are covered by the PACT Act's burn pit and airborne hazard presumptions. Covered locations include:
Afghanistan, Iraq, Kuwait, Saudi Arabia, Bahrain, Oman, Qatar, United Arab Emirates, Jordan
Egypt, Turkey, Syria, Uzbekistan, and surrounding airspace
Somalia and Djibouti (after September 19, 2001)
Other designated locations added by VA under the law
Vietnam Era Veterans (Expanded Agent Orange)
The PACT Act expanded the locations where Agent Orange exposure is presumed, adding:
Veterans who served in or near the Korean Demilitarized Zone (DMZ) between 1967–1971
Veterans who served in any country where Agent Orange was tested or stored (beyond the previous Vietnam/Korean DMZ list)
Veterans aboard ships that operated in Vietnamese inland waterways ("Blue Water Navy" veterans already expanded under the Blue Water Navy Vietnam Veterans Act, now fully integrated into PACT Act framework)
Radiation-Exposed Veterans
Veterans exposed to ionizing radiation during nuclear tests, occupation of Hiroshima or Nagasaki, or other specific radiation events are covered with expanded presumptive conditions under the PACT Act.
No Nexus Letter Required for Presumptives
This is the critical distinction: for PACT Act presumptive conditions, you do NOT need a nexus letter proving that your condition was caused by service. VA presumes the connection if you have (1) the qualifying exposure history and (2) a current diagnosis of a covered condition. This fundamentally lowers the barrier to approval compared to standard direct service connection claims.
You Don't Need to Prove Causation
The whole point of presumptive service connection is that VA accepts the link without you having to prove it. You establish the exposure (where you served, what you were exposed to) and present your current diagnosis. The causal chain is presumed by law. A nexus letter is not required — though for conditions that are NOT listed as presumptive, a nexus letter remains important.
The PACT Act created presumptive service connection for the following cancers in veterans with qualifying burn pit/airborne hazard exposure:
Cancer Category
Specific Conditions Included
Respiratory cancers
Squamous cell carcinoma of the head/neck, larynx, bronchus, lung, trachea
Reproductive cancers
Cervical, uterine, ovarian, breast (in some circumstances), testicular
Urinary tract cancers
Bladder, kidney, ureter, urethra
Lymphatic/hematopoietic
Hodgkin's and non-Hodgkin's lymphoma, multiple myeloma, leukemia
Melanoma
Malignant melanoma of the skin
Squamous cell carcinomas
Any squamous cell carcinoma not listed elsewhere
Other cancers
Glioblastoma, pancreatic cancer, and others designated by VA
Gulf War Illness Presumptives
Gulf War illness (chronic multi-symptom illness) remains a separate presumptive category. Veterans who served in the Gulf War theater can claim undiagnosed illnesses or medically unexplained chronic multi-symptom conditions (including fatigue, skin conditions, headache, muscle pain, neurocognitive symptoms, and others) without a definitive diagnosis.
Expanded Agent Orange Presumptives (Vietnam Era)
All conditions previously listed under 38 CFR § 3.309(e) as Agent Orange presumptives continue, now expanded by the PACT Act to include:
Hypertension (high blood pressure) — one of the most significant additions affecting millions of Vietnam veterans
Monoclonal Gammopathy of Undetermined Significance (MGUS)
All previously established Agent Orange presumptives: Type 2 diabetes, IHD, non-Hodgkin's lymphoma, Parkinson's disease, prostate cancer, respiratory cancers, soft tissue sarcoma, and others remain in force
Radiation Exposure Presumptives
Veterans who participated in atmospheric nuclear tests, occupied Hiroshima or Nagasaki post-WWII, or were assigned to certain other radiation-exposed duty locations have presumptive service connection for a specific list of radiogenic diseases including various cancers. The PACT Act added additional cancers to this list.
The Toxic Exposure Screening (TES)
One of the most important — and most underutilized — provisions of the PACT Act is the Toxic Exposure Screening (TES). Under the law, VA is required to offer a standardized screening questionnaire to every enrolled veteran during primary care appointments.
Why the TES Matters for Your Claim
Completing the TES creates a dated, official VA record of your toxic exposure history. If you later file a disability claim citing burn pit exposure or chemical exposure, having a TES record from your VA primary care visit corroborates your exposure history with documented evidence.
What the TES Asks
The screening asks about:
Deployment locations and dates
Proximity to burn pits and trash fires
Exposure to chemicals, solvents, or industrial agents
Radiation exposure history
Agent Orange exposure (Vietnam-era veterans)
Gulf War-related exposures
Any other known toxic exposures during service
How to Complete the TES
The TES is administered at VA primary care visits — but many veterans report that it was not offered to them despite the mandate. If your primary care provider has not offered you the screening:
Ask your VA primary care provider explicitly: "I'd like to complete the Toxic Exposure Screening required by the PACT Act."
Contact your VA Patient Aligned Care Team (PACT) team through My HealtheVet secure messaging
You can also report your exposure history via VA's online environmental exposure submission tool
Get the TES Done Before You File
Completing the TES before filing your disability claim establishes your exposure history in VA's system before the claim is even created. When a VA rater reviews your claim, they'll see the documented TES record, which aligns with your claimed exposure basis. This is free, takes 10–15 minutes, and can only help your claim.
Step-by-Step: Filing VA Form 21-526EZ
Step 1
Gather Your Service Records and Medical Documentation
Before opening Form 21-526EZ, gather:
DD-214 (Certificate of Release from Active Duty) — you need your service dates, character of discharge, and MOS/AFSC
Military personnel file (eMPF for Air Force; PERMS for Army) — shows duty stations and deployments
Deployment orders or overseas service records
Medical records showing current diagnosis of claimed condition(s)
Buddy statements from servicemembers who can attest to your exposure
Completed TES record (from your VA primary care visit)
Step 2
Access VA Form 21-526EZ Online
The form is available at VA.gov. You can complete it entirely online through the VA disability compensation application portal (VA.gov/disability/file-disability-claim-form-21-526ez/). Online filing is recommended because:
You get an immediate date-stamped submission confirmation establishing your effective date
VA can access some of your existing records automatically
You can save progress and return to complete it over multiple sessions
You upload supporting documents directly
Step 3
Complete the Toxic Exposure Section (Critical for PACT Act)
Form 21-526EZ was updated after the PACT Act to include specific questions about toxic exposure. This section is mandatory to identify your claim as PACT Act-related. You must:
Answer "Yes" to toxic exposure questions and specify the type (burn pit, Agent Orange, radiation, etc.)
List the specific locations where exposure occurred (base names, countries, dates)
Indicate the duration and frequency of exposure where known
Note any medical treatment received in service related to exposure
Step 4
List Every Condition You're Claiming
In the conditions section, list each specific condition separately. For PACT Act presumptives:
Use the specific medical name of the condition (e.g., "Non-Hodgkin's Lymphoma" not just "cancer")
Note "Presumptive — PACT Act" next to each PACT Act condition
Do not omit conditions you're unsure about — let VA make the rating determination
Include secondary conditions (e.g., side effects of cancer treatment) that you want rated
Step 5
Submit a Statement in Support of Claim (VA Form 21-4138)
Attach a written personal statement using VA Form 21-4138. This is separate from the 21-526EZ and gives you space to tell your story in your own words. Your statement should explain:
Where you served and when
Specific exposures: how close you were to burn pits, how often, what was burned
Any symptoms that began during or shortly after the exposure period
When you received your diagnosis and from whom
How the condition affects your daily life and ability to work
Step 6
Submit and Confirm Receipt
After submitting online, save your confirmation page and confirmation number. VA will send a letter acknowledging receipt and your claim's effective date within 5–7 business days. The effective date for disability benefits is typically the date VA receives your completed claim — this is why filing promptly matters.
Evidence to Gather Before Filing
Exposure Evidence
Deployment orders: Document which locations you served in and when
Unit records: If your unit deployed to a PACT Act-covered location, unit histories (often obtainable through the National Archives) corroborate your deployment
Buddy statements: Written statements from servicemembers who can attest to shared exposure are powerful corroborating evidence
Photographs: Photos taken during deployment showing burn pits or hazardous conditions have been accepted as corroborating evidence
DoD Burn Pit Registry: If you registered with the Airborne Hazards and Open Burn Pit Registry, include that registration number in your claim
Medical Evidence
Pathology reports: For cancer claims, the pathology or biopsy report confirming diagnosis is essential
Physician letters: A letter from your treating oncologist or specialist confirming diagnosis, current status, and treatment
VA medical records: If you're enrolled in VA health care, VA already has access to your VA records — but private medical records must be submitted separately
Imaging reports: CT scans, PET scans, MRIs relevant to your condition
Don't Wait for "Perfect" Evidence
File your claim as soon as possible to establish your effective date. You can submit additional evidence after filing. For PACT Act presumptive conditions, VA is required to give you benefit of the doubt on the exposure-to-condition link — your primary burden is proving you were in the covered location and that you have the diagnosis. Don't delay filing waiting for more records.
Adding PACT Act Conditions to an Existing Claim
If you already have an active pending claim with VA, you can add PACT Act conditions to it without filing a completely new application. The process depends on the status of your current claim:
If Your Claim Is Still Pending (Not Yet Decided)
Contact VA by phone (1-800-827-1000), online message, or through your VSO
Request to "add a new condition" to your existing pending claim
Provide the condition name and note "PACT Act presumptive"
VA will add the new condition to your pending claim and process it together
If Your Claim Was Recently Decided (Within 1 Year)
Within one year of a VA decision, you can file a Supplemental Claim (VA Form 20-0995) with new and relevant evidence. For PACT Act conditions not previously claimed, the PACT Act itself may constitute new and relevant evidence justifying a supplemental claim even if your exposure was the same.
Previously Denied Claims: The Supplemental Route
If you previously filed a claim that was denied because VA couldn't establish service connection for a condition that is now presumptive under the PACT Act, you have options:
VA's Automatic Review Obligation
Under the PACT Act, VA is required to automatically review certain previously denied claims that may now qualify under the new presumptives. Veterans who had claims denied for conditions now covered by PACT Act presumptives should have received or should receive a review notice from VA. If you haven't, contact VA or your VSO to inquire whether your denied claim has been flagged for automatic review.
File a Supplemental Claim (Form 20-0995)
If your previously denied claim has not been automatically reviewed, or if you want to proactively ensure it's reconsidered:
File VA Form 20-0995 (Decision Review Request: Supplemental Claim)
In the "New and Relevant Evidence" section, cite the PACT Act (Public Law 117-168) as establishing presumptive service connection for your condition
Include your current diagnosis documentation
Reference your deployment history establishing exposure in a covered location
The supplemental claim pathway is important because it can preserve an earlier effective date. If your original claim was filed before August 10, 2022 (the PACT Act enactment date) and your condition is now presumptive, winning on supplemental may result in retroactive pay back to your original claim date — potentially worth thousands or tens of thousands of dollars.
Effective Date for Previously Denied Claims
The effective date rules for PACT Act supplemental claims are complex. Generally, if you filed an original claim before August 10, 2022, and that claim was denied, and VA's PACT Act automatic review grants service connection — your effective date may go back to your original claim date. This can mean significant retroactive payments. Discuss effective date strategy with a VA-accredited attorney before filing your supplemental claim.
Effective Dates and Retroactive Pay
The effective date — the date from which VA pays disability compensation — is one of the most financially significant aspects of any PACT Act claim.
Standard Effective Date: Date of Claim
For new PACT Act claims, the effective date is the date VA receives your completed claim (or the date entitlement arose, whichever is later). This is why filing promptly matters: every month you delay filing is a month of retroactive pay you cannot recover.
PACT Act Retroactive Pay Window
The PACT Act created a special retroactivity window for veterans who filed claims within one year of the law's enactment (before August 10, 2023). Veterans who filed in that window and were granted benefits may have an effective date back to August 10, 2022, even if their claim wasn't decided until later. If you filed before August 10, 2023, check with your VSO or VA to ensure your effective date was applied correctly.
If VA's automatic PACT Act review grants you benefits, your effective date may trace back to your original claim date — potentially years before 2022. If you previously filed a claim that was denied and it's now being reviewed, the potential retroactive pay could be substantial.
PACT Act C&P Exam Tips
Not all PACT Act claims require a C&P exam. For clearly documented presumptive conditions, VA may grant the claim based on file review alone. But if you are scheduled for a C&P exam:
Confirm the examiner knows this is a PACT Act claim. Remind the examiner that you're claiming under PACT Act presumptive — the exam should not require them to opine on causation for presumptive conditions.
Provide your deployment records. Bring documentation of your deployment locations and dates to confirm your exposure history.
Discuss all symptoms. Even if your primary diagnosis is established, the examiner should document the full extent of your condition and any secondary effects.
Document current severity. The C&P exam is also used to rate the severity of your condition. Describe your worst days honestly, including functional limitations, pain levels, and any limitations on work or daily activities.
For cancer claims: Bring pathology reports, treatment records, and a letter from your oncologist summarizing your diagnosis, treatment status, and prognosis.
Common Mistakes That Delay or Sink PACT Act Claims
Not completing the toxic exposure section of 21-526EZ. The exposure section is what flags your claim as PACT Act-related. Skipping it or being vague can route your claim as a standard direct service connection claim — requiring more evidence than a presumptive.
Filing without confirming your deployment location is covered. Verify that the specific country, base, or operation qualifies under the PACT Act covered locations list before citing it as your exposure basis.
Not claiming secondary conditions. Many veterans with PACT Act cancers have secondary conditions — side effects of chemotherapy, radiation damage to adjacent organs, depression, PTSD from the cancer diagnosis and treatment. Claim these separately.
Waiting for the "right time." There is no perfect time to file. Your effective date is locked to your filing date. Every month you wait is a month of retroactive pay lost.
Not registering with the Airborne Hazards Registry. Registering with the DoD Airborne Hazards and Open Burn Pit Registry creates official documentation of your exposure. Do this whether or not you're currently filing a claim.
Filing only the 21-526EZ without supporting statements. The personal statement (21-4138) describing your exposure in detail is important corroborating evidence, especially if your deployment records don't specifically note burn pit proximity.
