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:

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:

Vietnam Era Veterans (Expanded Agent Orange)

The PACT Act expanded the locations where Agent Orange exposure is presumed, adding:

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.

Presumptive Conditions Under the PACT Act

Burn Pit / Airborne Hazard Cancers (Post-9/11 & Gulf War Veterans)

The PACT Act created presumptive service connection for the following cancers in veterans with qualifying burn pit/airborne hazard exposure:

Cancer CategorySpecific Conditions Included
Respiratory cancersSquamous cell carcinoma of the head/neck, larynx, bronchus, lung, trachea
Reproductive cancersCervical, uterine, ovarian, breast (in some circumstances), testicular
Urinary tract cancersBladder, kidney, ureter, urethra
Lymphatic/hematopoieticHodgkin's and non-Hodgkin's lymphoma, multiple myeloma, leukemia
MelanomaMalignant melanoma of the skin
Squamous cell carcinomasAny squamous cell carcinoma not listed elsewhere
Other cancersGlioblastoma, 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:

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:

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:

  1. Ask your VA primary care provider explicitly: "I'd like to complete the Toxic Exposure Screening required by the PACT Act."
  2. Contact your VA Patient Aligned Care Team (PACT) team through My HealtheVet secure messaging
  3. 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:

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:

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:

Step 4

List Every Condition You're Claiming

In the conditions section, list each specific condition separately. For PACT Act presumptives:

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:

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

Medical Evidence

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)

  1. Contact VA by phone (1-800-827-1000), online message, or through your VSO
  2. Request to "add a new condition" to your existing pending claim
  3. Provide the condition name and note "PACT Act presumptive"
  4. 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:

  1. File VA Form 20-0995 (Decision Review Request: Supplemental Claim)
  2. In the "New and Relevant Evidence" section, cite the PACT Act (Public Law 117-168) as establishing presumptive service connection for your condition
  3. Include your current diagnosis documentation
  4. 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.

Previously Denied Claims: Supplemental Effective Dates

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:
