A Denial Letter Is a Starting Line, Not a Finish Line
Your client worked 14-hour shifts on a military base in Afghanistan. A knee gave out climbing a guard tower. The employer filed the LS-1, the carrier acknowledged coverage, and then six weeks later a two-page letter arrived: claim denied, insufficient medical evidence of causation.
This happens constantly. DBA carriers deny claims for dozens of reasons, from missed filing deadlines to disputes over whether an injury arose "in the course of employment" overseas. The denial letter itself is formulaic. What matters is what you do in the 30 to 90 days after it lands on your desk.
The Defense Base Act incorporates the Longshore and Harbor Workers' Compensation Act procedural framework. That framework gives your client three distinct stages to challenge a denial: an informal conference with OWCP, a formal hearing before an Administrative Law Judge, and appellate review by the Benefits Review Board. Each stage has its own rules, its own evidentiary standards, and its own strategic considerations.
Across 4,983 DOL case summary records tracked in ClaimTrove data, carrier denials cluster around predictable patterns. Some carriers contest causation aggressively. Others focus on coverage disputes or statute of limitations defenses. Understanding what you are up against before you pick your strategy can save months of wasted effort.
This article walks through each post-denial step, the evidence that matters at each stage, and the common denial categories that trigger specific procedural responses.
What Are the Most Common Reasons DBA Carriers Deny Claims?
DBA carrier denials generally fall into four categories. Each one triggers a different defensive strategy and requires different evidence to overcome.
Late filing under Section 13. The LHWCA requires written notice to the employer within 30 days of injury and a formal claim filing within one year. Carriers routinely deny claims where the claimant missed these windows. Occupational disease claims get a longer runway because the clock starts when the claimant knew or should have known the condition was work-related. If your client's denial cites Section 13, your first task is establishing exactly when the claimant became aware of the condition's occupational origin. Attorneys handling DBA statute of limitations disputes under Section 913 regularly find that carriers apply the awareness date too aggressively.
Causation disputes. The carrier accepts that the claimant worked overseas under a covered contract but disputes that the injury or illness arose from employment. This is the most litigated denial category in DBA cases. Carriers hire independent medical examiners to produce reports contradicting the treating physician. Your response depends on whether you can invoke the Section 20(a) presumption, which shifts the burden back to the carrier.
Coverage disputes. The carrier argues that the claimant's employer was not covered under the DBA, that the work location does not qualify, or that the claimant was not an "employee" under the Act. These denials are particularly common with subcontractor employees and third-country nationals. Resolving them requires tracing the prime contract, the subcontract chain, and the insurance carrier assignment for each layer. Coverage disputes often require a structured carrier investigation workflow before you can even respond to the denial.
Maximum medical improvement and benefit disputes. The carrier does not deny the initial claim outright but disputes the duration or amount of benefits. This includes premature TTD termination, refusal to authorize medical treatment, and disputes over disability ratings. Carriers fighting TTD termination use surveillance and functional capacity evaluations to argue the claimant can return to work.
How Does the OWCP Informal Conference Work After a Denial?
The first post-denial step is requesting an informal conference through the Office of Workers' Compensation Programs, Division of Longshore and Harbor Workers' Compensation. This is not optional in practice. OWCP handles the initial administrative processing of all DBA claims, and the informal conference is your first opportunity to present evidence and argue against the denial.
When OWCP receives a disputed claim, a claims examiner reviews the file and schedules an informal conference. Both parties, the claimant's attorney and the carrier's representative, participate. The conference is not a hearing. There is no sworn testimony, no formal rules of evidence, and no binding decision. The claims examiner issues a recommendation, which the carrier can accept or reject.
The practical value of the informal conference is threefold. First, it forces the carrier to articulate its denial rationale in detail, often revealing weaknesses you can exploit later. Second, you get to submit additional medical evidence, employment records, and contract documentation before the case escalates. Third, a significant percentage of claims settle at this stage because the carrier's cost-benefit analysis changes once an attorney enters the picture.
Prepare for the informal conference as if it were a hearing. Submit a position paper with medical records, employment verification, and contract documentation. If the denial is causation-based, include a detailed narrative report from the treating physician that directly addresses the carrier's IME findings. The claims examiner's recommendation carries weight even though it is not binding. A strong recommendation in your favor puts settlement pressure on the carrier.
If the informal conference does not resolve the dispute, either party can request a formal hearing before an OALJ. This is where the procedural landscape shifts dramatically.
What Happens at a Formal Hearing Before an Administrative Law Judge?
The formal hearing stage is where DBA claim denials get decided on the merits. An Administrative Law Judge from the Office of Administrative Law Judges conducts a trial-type proceeding with sworn testimony, documentary evidence, cross-examination, and a written decision.
To get here, you file a request for hearing with the OALJ after the informal conference fails to produce a resolution. The ALJ is assigned from the district office with jurisdiction. Pre-hearing procedures include discovery, witness lists, and exhibit exchanges. The hearing itself typically takes one to three days depending on complexity.
The Section 20(a) presumption is your most powerful tool at this stage. Under Section 20(a) of the LHWCA, if the claimant establishes a prima facie case that the injury or death occurred and a working condition existed that could have caused it, the claim is presumed compensable. The burden then shifts to the carrier to rebut the presumption with substantial evidence. Understanding how the Section 20(a) presumption makes DBA claims compensable by default is foundational to every contested hearing.
The carrier rebuts the presumption by producing substantial evidence that the injury was not work-related. An IME report alone can be sufficient to rebut the presumption, but rebuttal does not end the inquiry. Once rebutted, the ALJ weighs all the evidence as a whole and makes a determination. The claimant no longer carries the burden of proof at this stage. Instead, the ALJ evaluates the evidence on both sides.
ClaimTrove's database contains 5,022 OALJ decisions spanning 1993 through 2025. These decisions reveal patterns in how ALJs evaluate specific types of denials. Causation disputes involving orthopedic injuries, for example, follow different evidentiary paths than PTSD claims or occupational disease cases. Carrier-specific litigation strategies also emerge across decisions. Some carriers consistently retain the same medical experts, producing predictable IME arguments that experienced practitioners learn to counter.
The ALJ's decision is a written order with findings of fact and conclusions of law. Either party can appeal to the Benefits Review Board.
How Does the Benefits Review Board Appeal Process Work?
The Benefits Review Board reviews ALJ decisions for errors of law and determines whether the ALJ's factual findings are supported by substantial evidence. The BRB does not conduct new hearings or accept new evidence. It reviews the existing record.
You have 30 days from the ALJ's decision to file a notice of appeal with the BRB. The appeal brief is due 60 days after the notice. The responding party gets 30 days to file a response brief. The BRB typically issues decisions 12 to 18 months after briefing is complete, though timelines vary.
The standard of review matters. The BRB will not overturn an ALJ's factual findings unless they are unsupported by substantial evidence or infected by legal error. This means the ALJ hearing is where you win or lose the case on the facts. The BRB stage is about preserving legal arguments and correcting misapplications of the statute.
Common BRB reversal grounds include: the ALJ failed to properly apply the Section 20(a) presumption, the ALJ misallocated the burden of proof, the ALJ excluded relevant evidence, or the ALJ applied an incorrect legal standard to a coverage or causation question. If the BRB reverses, it typically remands to the ALJ for further proceedings rather than entering a final order itself.
After the BRB, the losing party can seek review in the appropriate United States Court of Appeals. Federal circuit court review is rare in DBA cases, but it does happen, particularly on novel coverage questions involving overseas contract work.
What Evidence Should You Gather Immediately After a Denial?
The 30 days after a denial letter arrives are the most important window in the case. Evidence degrades. Witnesses rotate out of theater. Employers restructure or lose subcontracts. Move fast.
Medical evidence. Obtain the treating physician's complete records, including the initial evaluation, diagnostic imaging, treatment notes, and any narrative reports. If the carrier relied on an IME to deny the claim, get a copy of the IME report immediately and have your client's doctor address its findings point by point. The ALJ will weigh competing medical opinions, and a detailed rebuttal from the treating physician carries significant weight.
Employment and contract documentation. Secure the employment contract, the DD-93 or equivalent deployment documentation, and any records showing the claimant's work location and duties. For coverage disputes, you need the prime contract number, the subcontract chain, and the carrier assignment for each tier. Identifying the correct DBA insurance carrier early prevents coverage disputes from derailing the claim at the hearing stage.
Incident documentation. Collect the LS-1 (employer's first report of injury), the LS-202 (employer's supplementary report), witness statements, incident reports, and any photographs or video from the work site. Military base access logs and convoy manifests can establish the claimant's presence at the injury location.
Prior claim history. Search for any previous DBA or LHWCA claims filed by the same claimant. Carriers routinely raise pre-existing condition defenses, and knowing the claim history lets you address this proactively. ClaimTrove data shows that across 30,631 FOIA database filings, many claimants appear multiple times with different employers and carriers, creating a documented injury timeline that can either support or undermine a new claim.
Practitioners who spot red flags in DBA investigations early tend to resolve denials faster. Missing contract documentation, employer name changes, and carrier transitions mid-contract are all signals that the denial may involve a coverage dispute masquerading as a causation defense.
How Do Carrier Denial Patterns Vary Across the DBA Market?
Not all carriers deny claims the same way. The DBA insurance market is concentrated among a relatively small number of authorized carriers, and each has developed distinct litigation strategies over the past two decades of overseas contracting.
ClaimTrove tracks 637 authorized DBA carriers, but the actual market is far more concentrated than that number suggests. A handful of carrier families write the majority of DBA policies, and each family has subsidiaries, TPAs, and legacy entities that complicate identification. When a denial letter arrives from a TPA rather than the actual carrier, you may be litigating against the wrong entity if you do not trace the insurance relationship back to its source.
Across 5,022 OALJ decisions in ClaimTrove's database, carrier-specific patterns emerge in denial strategy, expert witness selection, and settlement behavior. Some carriers aggressively contest every TTD claim past 90 days. Others focus their litigation budgets on high-value permanent disability cases while settling smaller claims quickly. These patterns are not publicly documented. They emerge only from systematic analysis of decision outcomes over time.
The mandatory agency contracts add another layer. During specific periods, the State Department, USACE, and USAID required contractors to obtain DBA coverage through designated carriers. If your client's denial involves a contract under one of these mandates, the carrier assignment is predetermined, and coverage disputes take on a different character. The carrier cannot argue it did not cover the employer during the mandate period.
Understanding which carrier you are dealing with, its typical denial posture, and how ALJs have ruled on similar denials from that carrier gives you a tactical advantage before you ever file a hearing request. This is exactly the kind of pattern analysis that requires systematic data, not anecdotal experience from a handful of cases.
ClaimTrove's investigation engine searches across 18 federal data sources and 5,022 OALJ decisions to surface carrier denial patterns, precedent outcomes, and coverage history for your specific claim. Run a carrier investigation before your next informal conference.
What Timeline Should You Expect From Denial to Resolution?
DBA claim denials do not resolve quickly. Understanding the realistic timeline helps you manage client expectations and plan your litigation strategy.
Informal conference: 60 to 120 days from the denial to a scheduled conference. The claims examiner's recommendation typically follows within 30 days. If settlement discussions begin, add another 30 to 90 days.
Formal hearing: 6 to 12 months from the hearing request to the actual hearing date. Pre-hearing discovery and motions consume most of this time. The ALJ's written decision typically arrives 30 to 90 days after the hearing concludes, though some complex cases take longer.
BRB appeal: 18 to 24 months from the notice of appeal to a BRB decision. Briefing takes 4 to 6 months. The BRB's decision queue adds 12 to 18 months.
Total timeline: A denial that goes through all three stages can take 3 to 4 years to resolve. Most cases settle before the ALJ hearing or shortly after the hearing but before the decision issues. The carrier's settlement posture often shifts after it sees the claimant's hearing presentation and witnesses.
Interim benefits may be available during the appeals process. If the carrier paid benefits before the denial, seek an order continuing those benefits pending resolution. The ALJ has authority to order interim payments in appropriate cases, and failing to request them leaves your client without income during a multi-year process.
Every week you delay after receiving a denial letter is a week of lost leverage. Carriers count on claimants and their attorneys moving slowly. The procedural framework rewards early, aggressive action. Gather your evidence, identify the carrier's denial pattern, and choose your forum strategically.
