The PACT Act—signed into law in August 2022—represents the largest expansion of VA benefits in decades, opening the door to presumptive service connection for millions of veterans exposed to burn pits, Agent Orange, contaminated water, and other toxic hazards. But clinical documentation of a diagnosis is still required. If you haven’t yet gathered medical evidence of your diagnoses or scheduled a toxic exposure screening, the final quarter of 2025 is your window to act before year-end medical processing slowdowns take hold.
Here’s how to organize your medical history and clinical documentation before the calendar flips.
Quick Refresher: Who the PACT Act Helps
The PACT Act establishes presumptive service connection for conditions linked to toxic exposures during specific eras and locations. If you have a presumptive condition and served in a covered location or time period, you don’t need to prove causation—the VA assumes your condition is service-connected based on your service records and a current diagnosis.
Covered eras and locations
Post-9/11 veterans (burn pit exposure):
- Afghanistan, Djibouti, Egypt, Jordan, Lebanon, Syria, Uzbekistan, Yemen, and airspace above these countries (September 11, 2001–present)
- Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, United Arab Emirates, Oman, and airspace above these countries (August 2, 1990–present)
- Any other location where the VA determines burn pits or toxic exposures occurred
Vietnam-era veterans (Agent Orange):
- Vietnam, including the Republic of Vietnam and its offshore waters (January 9, 1962–May 7, 1975)
- Thailand (January 9, 1962–June 30, 1976) at U.S. military bases
- Korea at or near the DMZ (September 1, 1967–August 31, 1971)
- C-123 aircraft crew members who flew or worked on these planes (any era)
Gulf War veterans (other toxic exposures):
- Southwest Asia theater (including Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, UAE, Oman, Gulf of Aden, Gulf of Oman, Persian Gulf, Arabian Sea, Red Sea) from August 2, 1990–present
- Afghanistan from September 19, 2001–present
Camp Lejeune (contaminated water):
- Veterans, family members, and civilians who lived or worked at Camp Lejeune, North Carolina, for at least 30 cumulative days between August 1, 1953, and December 31, 1987
Presumptive conditions
The PACT Act covers dozens of conditions, including:
- Cancers: Brain, gastrointestinal, head/neck, kidney, lymphoma (Hodgkin’s and non-Hodgkin’s), melanoma, pancreatic, reproductive, respiratory (lung, bronchus, larynx, trachea)
- Respiratory: Asthma (diagnosed after service), chronic bronchitis, chronic obstructive pulmonary disease (COPD), chronic rhinitis, chronic sinusitis, constrictive bronchiolitis, emphysema, granulomatous disease, interstitial lung disease, pleuritis, pulmonary fibrosis, sarcoidosis
- Rare conditions: Glioblastoma, certain rare respiratory cancers

What to Do Now: Screenings and Records
October through early November is the ideal window to schedule screenings and request clinical records. Here’s your clinical action plan:
1. Schedule a toxic exposure screening
All veterans enrolled in VA health care are eligible for a free toxic exposure screening. This is a brief questionnaire and exam that documents:
- Your deployment history and potential exposures
- Current symptoms or conditions
- Recommendations for follow-up care or specialist referrals
The screening itself is not a disability exam, but it creates a medical record of your exposure and symptoms—essential documentation for medical evaluations.
How to schedule:
- Call your local VA Medical Center: Request a “PACT Act toxic exposure screening”
- Schedule online: Log into My HealtheVet or the VA Health and Benefits mobile app and request an appointment
- Walk-in: Some VAMCs offer walk-in screening during specific hours
Q4 timing tip: VA clinics reduce appointment availability during Thanksgiving week and the last two weeks of December. Schedule your screening for late October or early November to ensure it’s completed and documented before year-end.
2. Request your service records
Your service treatment records (STRs), personnel files, and deployment records establish when and where you were exposed. These are needed for clinical review:
- DD-214: Confirms service dates and locations. Request via eBenefits.VA.gov or Archives.gov/veterans.
- Service treatment records (STRs): Medical records from your time in service. Request via the National Archives’ eVetRecs system or submit Standard Form 180.
- Personnel and pay records: Document deployments and unit assignments. Request through the National Personnel Records Center (NPRC).
Allow 60–90 days for fulfillment. If you request now (October), you’ll have records in hand by late December—ideal timing for a thorough medical review.
3. Obtain current medical records
If you’ve been diagnosed with a presumptive condition since leaving service, gather:
- VA treatment records: Download via My HealtheVet > Blue Button or request at your local VAMC
- Private medical records: Contact your civilian providers and request copies of diagnoses, test results, and treatment notes
Key clinical documents include:
- Pathology reports (for cancer diagnoses)
- Pulmonary function tests (for respiratory conditions)
- Imaging reports (CT scans, X-rays showing lung damage or tumors)
- Specialist consultation notes (oncology, pulmonology, gastroenterology)
4. Document your clinical history and symptoms
A detailed personal history of your symptoms provides essential context for a medical evaluator. When preparing for an independent medical evaluation, be ready to discuss:
- Exposure details: Specifics regarding proximity to burn pits or other hazards. For example: “Our base had a burn pit operating 24/7 approximately 200 meters from my living quarters.”
- Symptom onset: When you first noticed symptoms like chronic cough, shortness of breath, or sinus infections.
- Condition progression: How your symptoms have developed or worsened since separation.
5. Buddy statements for clinical corroboration
Statements from fellow service members can corroborate your exposure and the timeline of your symptoms, which helps clinicians establish the history of a condition. These should focus on observed physical symptoms and environmental exposures.
Building Your Clinical Timeline
Our medical providers evaluate cases based on a clear exposure-to-diagnosis timeline. Organizing your medical history chronologically helps ensure all clinical factors are considered:
Timeline structure
Phase 1: In-service exposure (dates)
- Location(s): List all bases or areas where you were exposed
- Exposure type: Burn pits, Agent Orange, contaminated water, etc.
- Symptoms during service: Cough, skin rashes, headaches, or respiratory issues documented in STRs
Phase 2: Post-service symptoms (dates)
- First appearance: When you first noticed symptoms after separation
- Progression: How symptoms worsened over time
Phase 3: Diagnosis (dates)
- Diagnosis date and provider: The date and name of the physician who diagnosed the condition
- Supporting tests: Pulmonary function tests, CT scans, or biopsies
Example timeline
2009–2011: Deployed to Bagram Airfield, Afghanistan. Daily exposure to burn pit smoke. Documented respiratory symptoms in STRs.
2012: Separated from service. Persistent cough treated by civilian provider.
2015: Diagnosed with chronic sinusitis and asthma by VA Palo Alto. Started on daily medications.
2023: Diagnosed with interstitial lung disease after CT scan showed scarring.
This structure helps a clinician review the continuity of symptoms from exposure to diagnosis.
Independent Medical Evaluations and Next Steps
Once you’ve gathered your medical records and built your clinical timeline, you can seek independent medical services to document the severity and nature of your conditions.
Medical-Only Services
Our services are strictly limited to medical evaluations and the preparation of nexus letters or medical reports based on clinical judgment. We do not provide assistance with the filing, preparation, or tracking of VA claims.
- Independent Medical Evaluations: Documenting current diagnoses and functional limitations.
- Medical Nexus Letters: Clinical opinions regarding the relationship between your service and current medical conditions.
Filing Your Claim
For assistance with the legal and administrative aspects of filing your claim, we recommend contacting an accredited representative. These organizations provide free or accredited services to help you navigate the VA system:
- Disabled American Veterans (DAV): DAV.org
- Veterans of Foreign Wars (VFW): VFW.org
- American Legion: Legion.org
PACT Act Medical Evidence Expectations
The VA is processing PACT Act cases with a focus on presumptive connection, but clinical evidence of a current diagnosis is still the most critical factor. Ensuring your medical file is complete before you approach an accredited representative for filing can help avoid delays.
Common Clinical Documentation Gaps
Gap 1: Missing a Current Diagnosis
Solution: Ensure you have a current medical diagnosis from a qualified provider for the condition you are claiming. Presumptive status does not waive the requirement for a current diagnosis.
Gap 2: Incomplete Medical History
Solution: Gather all private and VA records to show the progression of your symptoms. A gap in treatment history can sometimes lead to requests for more evidence.
Gap 3: Missing Deployment Documentation
Solution: Ensure your service records confirm your presence in a covered location. If your records are incomplete, buddy statements or unit orders should be provided to your clinician for context.
