What Is a Defense Base Act Disability Claim?
A Defense Base Act (DBA) disability claim is a workers’ compensation claim filed by a civilian employee of a U.S. government contractor who is injured or becomes ill while working overseas. The Defense Base Act extends the Longshore and Harbor Workers’ Compensation Act (LHWCA) to cover these employees, providing wage-loss compensation, medical care, and, in fatal cases, survivor benefits.
The U.S. Department of Labor’s Office of Workers’ Compensation Programs (OWCP) administers DBA claims through the Division of Longshore and Harbor Workers’ Compensation (DLHWC). The process uses the same forms, benefit rates, and adjudication rules as the LHWCA. That means adjusters and attorneys must be familiar with the Longshore framework to handle DBA claims correctly.
Our team at NorCal Medical Consulting aligns medical documentation with OWCP standards from the initial file review. This helps ensure that impairment ratings, causal relationship opinions, and treatment records meet the evidentiary requirements the district office and administrative law judges expect.
Covered Work and Who Qualifies
The Defense Base Act covers civilian employees working outside the United States for U.S. government contractors and subcontractors. Coverage applies to specific types of work and locations, regardless of the employee’s nationality.
Covered employment under the DBA includes work for private employers on U.S. military bases or on any lands used by the U.S. for military purposes outside the United States, including U.S. Territories and possessions. It also covers work on public work contracts with any U.S. government agency, including construction and service contracts related to national defense or war activities performed outside the U.S.
Additional categories of covered work include contracts approved and funded by the U.S. under the Foreign Assistance Act performed outside the U.S., and work for American employers providing welfare or similar services outside the U.S. for the benefit of the Armed Services, such as the United Service Organizations (USO). Coverage also extends to injury or death occurring during employer- or U.S.-provided transportation to or from the place of employment.
Who Is Covered Under the DBA
All employees engaged in covered employment are protected under the DBA, regardless of nationality. This includes U.S. citizens, host country nationals, local hires, and third-country nationals. The Department of Labor’s Defense Base Act FAQ confirms that no distinction based on citizenship or residency status limits eligibility.
Exclusions from DBA Coverage
Certain employees are exempt from the DBA. The Act does not apply to employees covered by the Federal Employees' Compensation Act (FECA), employees engaged in agriculture, domestic service, or casual employment not in the usual course of the employer’s business, or a master or member of the crew of any vessel. Work performed under a grant or a cooperative agreement is also not covered under Section 1651(a)(4) of the DBA.
Determining whether an employee’s specific role and location trigger DBA coverage often requires careful review of the employment contract and the underlying government contract. Our team at NorCal Medical Consulting provides independent file reviews that help confirm coverage and align documentation with OWCP standards from the start.
Filing Deadlines and Required Forms
The Defense Base Act (DBA) runs on a set of statutory deadlines that claimants, adjusters, and attorneys must track from day one. Missing a filing window does not automatically forfeit a claim, but timely submission preserves every benefit pathway and avoids unnecessary procedural fights.
30-Day Written Notice to the Employer
An injured employee must give written notice of the injury to the employer on Form LS-201 (Notice of Employee’s Injury or Death) within 30 days of the incident. This rule, drawn from 33 U.S.C. § 912, covers all DBA claims except certain hearing-loss and occupational-disease cases, which have extended timeframes. The 30-day period is liberally construed by the Office of Workers’ Compensation Programs (OWCP), so late notice rarely bars a claim outright, but filing on time triggers the employer’s duty to authorize medical care and notify its insurance carrier.
One-Year Claim Filing (Form LS-203)
A formal claim for compensation must be filed with the OWCP on Form LS-203 (Employee’s Claim for Compensation) within one year after the date of injury or after the last payment of compensation, whichever is later. For occupational diseases, the window extends to two years from the date the employee became aware of the relationship between the disease and the employment. Claims are filed by mailing complete packets to the Jacksonville DLHWC Office (Charles E. Bennett Federal Building, 400 West Bay Street, Room 63A, Box 28, Jacksonville, FL 32202) or submitted electronically via the Longshore Secure Electronic Access Portal (SEAPortal). Our team at NorCal Medical Consulting routinely reviews DBA claims to ensure medical documentation meets OWCP standards from the outset, reducing the risk of denial on technical grounds.
Death Benefits and No Time Limit for Medical Care
Survivors seeking death benefits must file Form LS-262 within one year of the employee’s death and provide written notice to the employer on Form LS-201 within 30 days. Unlike disability compensation, medical benefits under the DBA have no filing deadline — an injured worker can claim necessary treatment at any time, as long as the injury remains related to the covered employment. The DBA also incorporates the Longshore Act’s provision for reasonable funeral expenses up to $3,000.
Employer Reporting Obligations
Upon learning of an injury that causes loss of one or more work shifts, the employer must file Form LS-202 (Employer’s First Report of Injury or Occupational Illness) with OWCP within 10 days. The employer must also notify its insurance carrier or claims administrator immediately and authorize medical treatment. Failure to secure DBA coverage can result in criminal prosecution, fines up to $10,000, imprisonment for up to one year, and personal liability for corporate officers.
| Form | Purpose | Filing Deadline |
|---|---|---|
| LS-201 | Notice of injury or death to employer | Within 30 days of injury or death |
| LS-203 | Employee’s formal claim for compensation | Within 1 year of injury or last payment (2 years for occupational disease) |
| LS-262 | Death benefit claim for survivors | Within 1 year of employee’s death |
| LS-202 | Employer’s first report of injury | Within 10 days if work shifts are lost |
Breaking Down DBA Disability Classifications
DBA disability is a legal determination that measures a worker’s inability to earn wages due to a work-related injury or illness covered under the Defense Base Act. The Act follows the same classification system as the Longshore and Harbor Workers’ Compensation Act, dividing disability into four types: temporary total, temporary partial, permanent total, and permanent partial.
Temporary total disability (TTD) applies when an employee is completely unable to work while recovering. Benefits are paid at two-thirds of the average weekly wage (AWW), beginning after the first three days of disability. Temporary partial disability (TPD) applies when the worker can return to light-duty or part-time work at reduced earnings. Compensation in that case is two-thirds of the difference between the pre-injury AWW and the worker’s current earning capacity.
Permanent total disability (PTD) means the worker is unable to perform any gainful employment in the open labor market. The DBA pays two-thirds of the AWW for life, with annual cost-of-living adjustments (COLA). Permanent partial disability (PPD) involves a lasting reduction in earning capacity and is calculated either through a statutory schedule for specific body parts or by comparing pre- and post-injury wages.
A permanent disability rating is not assigned until the worker reaches Maximum Medical Improvement (MMI). At that point, our physicians use the Sixth Edition of the Department of Labor’s Schedule for Rating Permanent Impairments to evaluate impairment, which includes the 3,000 Hz frequency for hearing loss required under the Schedule. NorCal Medical Consulting provides independent medical evaluations that align documentation with OWCP standards, reducing the risk of disputes during the rating process.
Insurance Requirements and Premium Calculation
The Defense Base Act (DBA) requires every U.S. government contractor and subcontractor to secure workers' compensation insurance for employees working overseas on qualifying contracts. This coverage must come from an insurance carrier authorized by the U.S. Department of Labor's Office of Workers' Compensation Programs (OWCP), which currently lists over 700 approved carriers and self-insured employers. Three major carriers — ACE-USA, AIG, and CNA — dominate the market, but contractors should compare quotes from multiple authorized carriers. The Federal Acquisition Regulation (FAR) mandates a clause in every covered contract requiring the prime contractor to secure this insurance before performance begins.
If a subcontractor fails to secure coverage, Section 5(a) of the Longshore Act deems the contractor the employer of the subcontractor's employees — and liable for paying benefits. The consequences escalate quickly. Section 38(a) makes failure to secure payment a misdemeanor punishable by a fine of up to $10,000, imprisonment for up to one year, or both. For corporate employers, the president, secretary, and treasurer are severally and personally liable — meaning officers can face fines and prison alongside the company. Injured employees can also sue the uninsured employer in tort court without the customary defenses of fellow-servant, assumption of risk, or contributory negligence under DBA Information.
Premium Calculation: Rate-per-Hundred Formula
Premiums use a rate-per-hundred formula. The assigned rate (e.g., $3.25 per $100 of payroll) times the total payroll for covered employees yields the annual premium, so a $500,000 payroll at a $3.25 rate gives $16,250 in premium. For most federal contracts, the insurance carrier — not the Department of Labor — sets the rate through its own underwriting review based on work classification, payroll size, claims history, and loss-control measures.
Rates are negotiable. Providing a documented safety program, detailed operational descriptions, and clean loss runs helps underwriters justify a lower rate. The one exception is USAID contracts, where OWCP sets the rate directly — no negotiation.
NorCal Medical Consulting works with adjusters and carriers to build medical records that support accurate claim classification and AWW calculation from day one. Aligning injury documentation with OWCP standards reduces the risk of premium disputes and helps carriers keep underwriting costs predictable for their policyholders.
| Scenario | Rate Basis | Premium Example | Key Consideration |
|---|---|---|---|
| Standard DBA policy | Carrier rate per $100 payroll | $3.25 × $500k = $16,250 | Negotiable with safety documentation |
| USAID contract | DOL-set rate per $100 payroll | Non-negotiable fixed rate | No carrier discretion |
| Self-insured employer | OWCP-authorized self-insurance | No premium paid; reserve required | Must maintain OWCP approval |
Medical Treatment: Rights and Responsibilities
Under the Defense Base Act, an injured employee has the right to choose their own physician for medical treatment. The employer must provide Form LS-1 (Request for Examination and/or Treatment) to authorize that care. If the employer delays or refuses, the employee can still seek treatment and request authorization afterward.
In a medical emergency, treatment can be obtained immediately and authorization requested after the fact. The DBA insurance carrier is responsible for the cost of medical transportation and repatriation for care. There is no time limit on medical benefits under the DBA — medical treatment continues as long as the injury requires it.
Medical benefits under the DBA cannot be commuted to a lump sum payment — they remain available for ongoing care. Our team at NorCal Medical Consulting routinely helps adjusters and attorneys ensure medical records align with OWCP standards from the outset, reducing disputes over treatment authorization and benefit continuity. For a deeper look at the full claims process, see our guide on Handling Defense Base Act Injury Claims: What You Should Know.
What you say to a workers' comp adjuster in the first interaction can shape the entire trajectory of the claim. Avoid statements that suggest the injury originated off the job or was pre-existing — phrases like "I hurt this at home first" or "this feels just like my old injury" signal causation issues that adjusters use to limit or deny coverage. Do not mention alcohol or drug use around the time of the injury, because intoxication is a complete bar to benefits under most federal and state schemes. Never downplay the injury by saying "I'm fine" or refusing treatment, as those statements weaken the medical record and can reduce a permanent impairment rating.
Do not agree to sign anything or accept a settlement before consulting counsel — telling the adjuster "I'll sign that now" or "I don't want to sue" signals that you lack representation and may be vulnerable to a lowball offer. Finally, avoid describing horseplay or deliberate acts — "I pulled his chair out as a joke" — because intentional injuries fall outside the scope of compensable workplace accidents. A well-documented medical record and clear communication with the adjuster are the best tools for keeping the claim on track.
Compensation Rates and Average Weekly Wage
Under the Defense Base Act, disability compensation for total incapacity equals two-thirds of the employee's average weekly wage (AWW), up to a current maximum rate. Death benefits are paid at one-half of AWW to a surviving spouse or one child, or two-thirds of AWW when two or more eligible survivors exist, also subject to the same weekly maximum. The DBA also covers reasonable funeral expenses of up to $3,000, as incorporated from the Longshore and Harbor Workers' Compensation Act.
The AWW should reasonably represent the employee's annual earning capacity. Documents used for the calculation include the employment contract, W-2 tax forms, payroll records, and Social Security data. When computing wages for overseas work, the AWW includes foreign housing allowances, cost-of-living adjustments, completion awards or bonuses, vacation and holiday pay, overtime, and per diem — provided none of these allowances are duplicative of one another.
There is no minimum compensation rate for DBA claims. Permanent total disability and death benefits receive an annual cost-of-living adjustment, and the maximum weekly rate is tied to the National Average Weekly Wage (NAWW). Claimants, adjusters, and counsel familiar with these calculation rules can more accurately project benefit amounts and avoid disputes. Our physicians at NorCal Medical Consulting routinely provide independent medical evaluations that frame disability findings in terms directly useful for AWW-based compensation calculations under OWCP standards.
Building a Durable Medical Record for OWCP
A durable medical record for a DBA claim under the Office of Workers' Compensation Programs (OWCP) is built from the first file review, not just the final report. Every document — intake notes, diagnostic imaging, treatment records, and the impairment rating — must align with OWCP's evidentiary standards or the claim becomes vulnerable to denial or delay.
The starting point is the OWCP's Division of Longshore and Harbor Workers' Compensation procedure manual and the Longshore regulations at 20 C.F.R. Parts 701–704. These outline what constitutes acceptable medical evidence: a physician's report that states a diagnosis, describes the causal relationship to the work injury, and assigns a permanent impairment rating using the Sixth Edition of the Department of Labor's Schedule for Rating Permanent Impairments. The AMA Guides to the Evaluation of Permanent Impairment serve as the supporting reference but the DOL Schedule is the controlling standard in DBA/LHWCA claims.
Aligning Documentation from Initial Review Through Final Report
Our team begins every case with a file review against those standards. We check that the treating physician's records include the mandatory elements: a clear history of the injury mechanism, serial objective findings, a diagnosis with ICD-10 code, and a treatment timeline showing when the employee reached Maximum Medical Improvement (MMI). If the treating records omit any of these, the impairment rating at the end is built on an incomplete foundation.
For the final Independent Medical Evaluation (IME) report, our physicians apply the Sixth Edition DOL Schedule directly — including the 3,000 Hz frequency requirement for auditory loss evaluations — rather than defaulting to the AMA Guides alone. This alignment matters because OWCP claims examiners and administrative law judges weigh impairment ratings that follow the DOL Schedule more heavily than those that do not.
NorCal Medical Consulting's Role: IMEs, Chart Reviews, and Expert Testimony
NorCal Medical Consulting provides IMEs and chart-based case reviews across the full scope of DBA-covered injuries: shoulder, neck, cervical/lumbar spine, hip, knee, ankle, foot, hand, peripheral nerve injuries, head trauma, burns, amputations, and hearing loss. Each report is written to withstand the Daubert standard and Federal Rule of Evidence 702, meaning the methodology is transparent, the data is reproducible, and the opinion is tied to peer-reviewed literature where applicable.
When a case proceeds to deposition or trial, our physicians serve as expert witnesses. Because the medical record was built from the start with OWCP standards in mind — rather than retrofitted after a dispute arises — our testimony addresses the claim's weaknesses before the opposing expert can expose them.
Settlement: Lump Sum vs. Ongoing Payments
There is no single "average" Defense Base Act settlement amount. The value of any DBA claim depends on the specific injury, permanent disability rating, average weekly wage (AWW), and future medical care costs. DBA settlements follow the same benefit framework as the Longshore and Harbor Workers' Compensation Act, which classifies disabilities into four categories: permanent total, temporary total, permanent partial, and temporary partial.
Permanent total disability pays two-thirds of the employee's AWW for life, with annual cost-of-living adjustments (COLA). Permanent partial disability is paid according to a statutory schedule or based on the wage-loss difference. Temporary total benefits also equal two-thirds of the AWW while the employee cannot work, and temporary partial benefits cover two-thirds of the difference between pre-injury AWW and current earning capacity.
A lump-sum settlement converts these ongoing benefits into a single payment. This provides immediate financial closure, but the trade-off is that the claimant forfeits future medical coverage and all future COLA increases. The U.S. Department of Labor must approve every DBA settlement, even after the carrier and claimant have agreed on terms, to ensure it meets the statutory requirements.
Our team at NorCal Medical Consulting evaluates each claim against the OWCP's current benefit rates and the Sixth Edition of the AMA Guides impairment schedule to determine an accurate settlement range tailored to the specific medical findings. Our team provides independent medical evaluations and chart-based reviews that withstand OWCP and Daubert scrutiny, helping adjusters, attorneys, and injured workers reach a settlement amount that reflects the true value of the claim.
Handling Disputes: Informal Conferences and Hearings
When a DBA claim is disputed, the first step is an informal conference with an OWCP claims examiner. This process is designed to resolve disagreements without formal litigation. The district director can approve settlements and issue awards in undisputed claims, but if the informal conference does not produce a resolution, either party may request referral to the Office of Administrative Law Judges (OALJ) for a formal hearing.
How long does a DBA claim take? A straightforward, well-documented claim with no disputes can begin paying benefits within a few weeks. If the claim is contested by the insurer, the process can run a year or more, especially if it proceeds to a formal hearing. Delays commonly arise from poor documentation, late reporting, or disputes over medical evidence.
The OALJ Hearing and Appeals Process
A formal hearing before an OALJ administrative law judge is a more structured proceeding where both sides present evidence and testimony. After the judge issues a decision, the losing party can appeal to the Benefits Review Board (BRB), and from there to the U.S. District Court or U.S. Court of Appeals. Because appeals can add months to the timeline, early resolution through the informal conference is usually the faster path.
The Role of a DBA Attorney and Fee-Shifting
The DBA is a fee-shifting statute, meaning that if certain conditions are met, the insurance company pays the claimant's attorney fees. This allows injured workers to secure experienced legal representation at no upfront cost. NorCal Medical Consulting's physicians frequently work with attorneys on contested claims, providing thorough Independent Medical Evaluations and expert testimony built to withstand scrutiny at the OALJ and BRB levels. An attorney's role includes gathering medical evidence, negotiating with insurers, and arguing at hearings — all of which can increase the likelihood of a favorable outcome.
For further information on dispute resolution steps, specific deadlines, and the forms involved, see the DBA FAQ from the U.S. Department of Labor.
Building a Manageable DBA Claim Process
A DBA claim comes down to three factors: timely notice, accurate average weekly wage (AWW) reporting, and thorough medical evidence aligned with OWCP standards. Missing any one of these causes delays or denials.
Our team at NorCal Medical Consulting supports carriers, attorneys, and injured workers at every stage — from initial file review through impartial Independent Medical Evaluations and expert testimony built to withstand the Daubert standard. Aligning documentation with OWCP requirements from the start keeps claims moving.
