Burn Pit Presumptive Conditions: What Firms Need in the Case Record

Burn pit presumptive conditions under the PACT Act turn on three facts: the veteran served in a qualifying location during a qualifying period, the veteran has a covered diagnosis, and the claim is structured to trigger the correct regulatory path. When all three are present, VA must presume exposure to fine particulate matter and must presume service connection without requiring the veteran to prove causation.

The Core Burn Pit Presumption and Its Regulatory Basis

38 CFR § 3.320^[1] establishes the foundational presumption. A veteran who served in the Southwest Asia theater during the Persian Gulf War (on or after August 2, 1990) or who served in Afghanistan, Syria, Djibouti, or Uzbekistan on or after September 19, 2001 is presumed to have been exposed to fine particulate matter. That presumption of exposure replaces the factual development VA would otherwise require to connect a condition to a toxic source.

The regulatory structure matters for how the case file is built. Because the presumption is exposure-based rather than condition-specific at this layer, the veteran does not need a documented burn pit encounter in their service records. Service in the covered location during the covered period is enough to establish exposure under 38 CFR § 3.320^[1]. The condition then has to match a recognized covered diagnosis to trigger the service connection presumption.

The statutory authority behind this structure is Title III of Public Law 117-168, the Honoring Our PACT Act of 2022. Pub. L. 117-168^[2] Section 302 established the exposure presumptions, and Section 202 gave VA authority to recognize additional conditions through rulemaking. That authority is what produced the January 2025 additions discussed below.

Covered Conditions: The Full PACT Act Presumptive List

VA recognizes a range of covered conditions for burn pit and airborne hazard claims. The current list includes constrictive or obliterative bronchiolitis, constrictive pericarditis, and certain cancers. VA.gov – Burn Pit and Environmental Hazard Eligibility^[3] maintains the public-facing enumeration of qualifying conditions, and it reflects the regulations currently in effect.

Two significant expansions took effect in January 2025.

Genitourinary Cancers Added Under 38 CFR § 3.320a

38 CFR § 3.320a^[4] added genitourinary cancers, including bladder and ureter cancers, as presumptive burn pit conditions. Published as an Interim Final Rule in January 2025 (Federal Register Docket No. 2024-31220), this regulation creates a two-layer presumption: qualifying service establishes presumed exposure to toxic substances and airborne hazards, including fine particulate matter, and that exposure establishes presumed service connection for covered genitourinary cancers. VA can rebut the presumption only with affirmative evidence that exposure did not occur.

Hematologic Malignancies Added Under 38 CFR § 3.320b

38 CFR § 3.320b^[5] added leukemias, multiple myeloma, myelodysplastic syndromes, and myelofibrosis. The Interim Final Rule (Federal Register Docket No. 2024-31776, published January 10, 2025) mirrors the 38 CFR § 3.320a structure. The same affirmative-evidence standard applies: VA bears the burden of disproving exposure, not the veteran.

For the case file, these additions create a specific review task. Active cases involving veterans with a genitourinary or hematologic diagnosis, and qualifying service, should be flagged for attorney review to confirm whether the condition now falls under a presumptive path that did not exist at the time of the original claim or denial.

Previously Denied Claims: The Change-in-Law Reopening Path

A burn pit claim denied before the PACT Act passed can be reopened. The mechanism is a Supplemental Claim on VA Form 20-0995. Normally, 38 CFR § 3.2501^[6] requires the claimant to submit new and relevant evidence to reopen a final denial on a Supplemental Claim. The PACT Act's change-in-law provision removes that threshold when the basis for reopening is the statutory and regulatory changes enacted by Pub. L. 117-168^[2].

VA's December 2022 Federal Register guidance on processing PACT Act claims confirms this. Federal Register – Processing PACT Act Claims (Dec. 22, 2022)^[7] The change in law itself is the basis for reopening. The claimant does not need to submit a new nexus opinion or additional service records to get past the threshold question.

The case-work implication is direct. Every previously denied burn pit case in the firm's inventory should be reviewed against the current condition list, including the January 2025 additions. If the veteran's diagnosis now falls under a recognized presumptive and service location qualifies, the file is a reopening candidate. That review can be done at the staff level. The determination of whether to file, which lane to use, and whether any other theory applies is an attorney decision.

Source Records That Establish Qualifying Service and Exposure

Staff can clear most of the threshold factual questions before the file reaches attorney review. The record types that matter:

Record Type	What to Confirm	Source
DD-214	Service dates, theater of service, component	Official Military Personnel File (OMPF) via National Personnel Records Center
Service treatment records	Deployment dates, duty locations, any respiratory or oncologic notations	OMPF or VA records
Personnel records / orders	Specific location of duty (Afghanistan, Djibouti, Syria, Uzbekistan, or Gulf theater) when DD-214 is ambiguous	OMPF
Airborne Hazards Registry records	Voluntary, but documents self-reported exposure history if the veteran enrolled	VA Public Health
VA medical records	Current diagnosis, treatment dates, diagnostic codes	VBMS or medical record request
Private medical records	Current diagnosis, specialist evaluations, recent imaging or biopsy results	Direct request to treating providers

Registry enrollment is not required. VA Public Health – Airborne Hazards and Burn Pit Exposures^[8] confirms that the Airborne Hazards and Open Burn Pit Registry is a voluntary program. Absence of registry records does not disqualify the claim and should not be listed as a gap that blocks filing. If registry records exist, they can corroborate the veteran's exposure history and go into the file as supporting source material.

The real threshold question is whether the DD-214 or personnel records confirm service in a named qualifying location during the relevant period. When the DD-214 lists a general theater code rather than a specific country, personnel orders or unit records may be needed to confirm location. That is a gap worth surfacing early.

How VA Develops and Rates BPOT Claims: The M21-1 Workflow

VA raters work from a defined adjudicative sequence for burn pit and other toxin (BPOT) claims. The operational manual governing that sequence is M21-1 Part VIII, Subpart ii, Chapter 2. M21-1, Part VIII, Subpart ii, Chapter 2, Section A^[9]

The rater checks three things before moving to a rating decision:

1. Qualifying service period and location, confirmed through service records.
2. A covered diagnosis in the claims file, confirmed through medical records.
3. Confirmation that the claimed condition matches a recognized burn pit presumptive under 38 CFR § 3.320^[1] or its subsections.

If service is confirmed and the diagnosis matches, the rater applies the presumption and moves to the rating schedule. Under M21-1 the rater does not send the claim for a C&P exam to establish nexus. The presumption replaces that step. M21-1, Part VIII, Subpart ii, Chapter 2, Section C^[10]

This has a practical consequence for case monitoring. If VA schedules a C&P exam on a burn pit presumptive claim and the exam is focused on establishing a nexus opinion, that is a development error. A nexus exam is not required when the presumption applies. The firm should identify that situation and flag it for attorney review before the exam record becomes part of the claims file.

Evidence Gaps and Attorney Review Triggers

Staff review for a burn pit presumptive claim should resolve three factual questions and flag any remaining issues for attorney judgment.

Factual questions staff can resolve:

• Does the DD-214 or personnel record confirm service in a qualifying location during a qualifying period?
• Does the file contain a current diagnosis that matches a covered condition under 38 CFR § 3.320^[1], 38 CFR § 3.320a^[4], or 38 CFR § 3.320b^[5]?
• Is this a previously denied claim where the change-in-law Supplemental Claim path applies?

Conditions that require attorney review before submission:

• Service records show deployment to the Gulf theater but do not confirm a specific qualifying country listed in 38 CFR § 3.320^[1]. Theory and development strategy need attorney direction.
• The diagnosis is a near-match for a covered condition but the medical records use terminology that does not map cleanly to the regulatory language. Whether to submit as-is, request a clarifying opinion, or pursue a direct service connection theory alongside the presumptive path is a judgment call.
• The veteran has both a covered presumptive condition and a possible secondary condition connected to it. Whether to file both claims together, sequentially, or under a combined theory requires attorney review.
• The prior denial was decided on the merits rather than on service location or period. An attorney needs to assess whether the prior adjudication creates any preclusion issue under the lane the firm plans to use.
• VA schedules a C&P exam on a presumptive claim and frames it as a nexus examination. The attorney should decide whether to object or prepare the veteran for an exam that should not be outcome-determinative.

The gap between "qualifying service confirmed" and "submission-ready" is often smaller on burn pit presumptive claims than on direct service connection claims. But smaller does not mean empty. Condition mapping, prior denial history, and secondary claim theory are all attorney-level decisions, regardless of how clean the service record looks.
