How Does the LHWCA Benefits Framework Apply to DBA Claims?
Your client was earning $185,000 per year as an explosive ordnance disposal technician in Afghanistan. His compensation package included base salary, hazard pay, overtime, per diem, and a housing allowance. After a blast injury left him with 40% permanent partial disability, the carrier calculated his average weekly wage using only base salary, excluding $62,000 in annual hazard pay and allowances. That calculation error would cost your client over $400,000 in lifetime benefits. Knowing how LHWCA benefits work is not optional. It is the difference between adequate compensation and a fraction of what the law provides.
The Defense Base Act does not create its own benefits structure. Section 1651 of the DBA incorporates the LHWCA (33 U.S.C. 901-950) in its entirety, including all benefit categories, calculation methods, and administrative procedures. Every DBA claim is adjudicated under LHWCA rules. When you research DBA benefits, you are researching LHWCA benefits applied to overseas contractor injuries.
The LHWCA provides four categories of disability compensation, death benefits, medical benefits, and vocational rehabilitation. Each category has specific calculation rules. The amounts are driven by the average weekly wage (AWW) and the applicable national maximum and minimum rates set by the Secretary of Labor under Section 6(b). Understanding these calculations at the outset of a case shapes your settlement valuation and litigation strategy.
What Are the Four Categories of Disability Compensation?
Temporary Total Disability (TTD) under Section 8(b) pays two-thirds of the claimant's AWW during the period when the claimant cannot work at all due to the injury. TTD continues until the claimant reaches maximum medical improvement (MMI), returns to work, or the carrier successfully shows the claimant can perform suitable alternative employment. There is no durational limit on TTD payments under the LHWCA, unlike many state workers' comp systems that cap temporary benefits at 104 or 156 weeks.
Temporary Partial Disability (TPD) under Section 8(e) compensates the wage differential when a claimant returns to work at reduced earnings before reaching MMI. The benefit is two-thirds of the difference between the pre-injury AWW and the claimant's current earning capacity. TPD is less common in DBA cases because overseas contractors often cannot return to modified duty in a war zone.
Permanent Partial Disability (PPD) comes in two forms: scheduled and unscheduled. Scheduled awards under Section 8(c)(1)-(20) cover specific body parts with fixed week durations. An arm is 312 weeks. A leg is 288 weeks. A hand is 244 weeks. Hearing loss in one ear is 52 weeks; both ears is 200 weeks. The benefit rate is two-thirds of AWW for the scheduled number of weeks, regardless of the claimant's actual earning capacity.
Permanent Total Disability (PTD) under Section 8(a) pays two-thirds of AWW for the duration of the disability. PTD applies when the claimant cannot perform any gainful employment. In DBA cases involving severe blast injuries, polytrauma, or debilitating PTSD, PTD claims are more common than in domestic longshore work. PTD benefits continue for life unless the claimant's condition improves enough to allow employment.
How Are Scheduled vs. Unscheduled Awards Calculated?
The distinction between scheduled and unscheduled awards is one of the most consequential in LHWCA practice. Scheduled awards under Section 8(c) compensate for loss of use of specific body parts listed in the statute. The claimant receives two-thirds of AWW multiplied by the number of weeks assigned to that body part, multiplied by the impairment percentage. A 50% loss of use of an arm yields 156 weeks of benefits (50% of 312 weeks).
Scheduled awards do not require proof of lost earning capacity. Even if the claimant returns to full-duty work at the same or higher wages, they still receive the scheduled award. This makes scheduled awards valuable for injuries to listed body parts where the claimant can continue working.
Unscheduled awards under Section 8(c)(21) cover injuries to body parts not listed in the schedule, such as the back, neck, head, lungs, and internal organs. Unscheduled awards also cover whole-body conditions like PTSD. The key difference: unscheduled awards require proof of actual or potential loss of earning capacity. The benefit rate is two-thirds of the difference between pre-injury AWW and post-injury earning capacity, paid for the duration of the disability.
In DBA practice, many injuries involve both scheduled and unscheduled components. A blast injury might cause hearing loss (scheduled, 200 weeks for binaural loss) plus traumatic brain injury (unscheduled, requiring earning capacity analysis). The claimant can receive both awards simultaneously because Section 8(c)(23) allows concurrent scheduled and unscheduled benefits. Getting this right doubles the benefit value in polytrauma cases.
How Is the Average Weekly Wage Calculated Under Section 10?
Section 10 of the LHWCA provides three methods for calculating AWW, applied in order. Section 10(a) applies when the claimant worked substantially the whole of the year preceding the injury. "Substantially the whole year" typically means at least 40-48 weeks. Under 10(a), the AWW equals total earnings during the year divided by 52 weeks.
Section 10(b) applies when the claimant did not work substantially the whole year. It uses the earnings of a similarly situated employee who did work the full year. If no comparable employee exists, Section 10(b) allows using the claimant's actual daily wage multiplied by the number of working days in a customary work week.
Section 10(c) is the catch-all provision. When neither 10(a) nor 10(b) produces a fair result, the ALJ can use any reasonable method to determine an AWW that reflects the claimant's earning capacity. Section 10(c) is frequently invoked in DBA cases because overseas contractor pay structures do not fit neatly into the 10(a) or 10(b) frameworks.
For DBA claimants, the AWW calculation is where the most money is at stake. Overseas contractors receive complex compensation packages. The critical question is which components count as "wages" under the LHWCA. Base salary unquestionably counts. Courts and ALJs have also included hazard pay, danger pay, overtime, uplift pay, and completion bonuses. Per diem and housing allowances generate more litigation. Some ALJs include them as part of the economic benefit of employment; others exclude them as reimbursement for expenses.
BRB decisions in ClaimTrove's database show inconsistent treatment of these components across different ALJs. Your strongest argument for inclusion is that the overseas assignment is the reason these payments exist, and the claimant would not have earned them in a domestic position. The carrier's counter-argument is that per diem and housing are expense reimbursements, not compensation for services.
What Are Section 10(f) Cost-of-Living Adjustments?
Section 10(f) provides annual cost-of-living adjustments (COLAs) to LHWCA benefits based on changes in the national average weekly wage. The Secretary of Labor publishes updated maximum and minimum compensation rates each October 1. Benefits for PTD, death, and certain PPD awards are adjusted annually so that the purchasing power of the benefit keeps pace with wage inflation.
The Section 10(f) adjustment applies automatically. Neither the claimant nor the carrier needs to file anything. The OWCP calculates the new rate and instructs the carrier to adjust payments. However, carriers do not always implement COLAs correctly or on time. Verifying that your client's benefit rate reflects current Section 10(f) adjustments is a routine but necessary part of DBA case management.
For FY2025, the national average weekly wage that drives LHWCA maximum compensation rates reflects cumulative increases since 2001. A claimant injured in 2005 with a PTD award has had nearly 20 years of COLAs applied to the original benefit rate. The compounding effect is substantial. Failing to verify COLA application can mean your client receives thousands of dollars less annually than the law requires.
The maximum weekly compensation rate for DBA/LHWCA claims is 200% of the national average weekly wage. The minimum is 50% of the national average weekly wage, or the claimant's actual AWW if lower. These bounds apply to TTD, PTD, and death benefits. Scheduled PPD awards are not subject to the maximum rate, a distinction that matters for high-wage earners with scheduled injuries.
How Are Death Benefits Calculated Under the DBA?
Section 9 of the LHWCA provides death benefits to surviving dependents. The surviving spouse receives 50% of the decedent's AWW for life or until remarriage. If the spouse remarries, they receive a lump sum equal to two years of benefits. Each surviving child receives an additional percentage, with the total for all dependents not exceeding 66 2/3% of AWW.
Funeral expenses up to the statutory maximum are also covered. The current maximum is adjusted periodically by OWCP. If there are no surviving dependents, funeral expenses are still paid, and the remaining benefit obligation goes to the Special Fund rather than to the employer or carrier.
Death benefits in DBA cases carry particular significance because of the high-fatality environments where contractors work. ClaimTrove's case summary data tracks death claim ("DEA") filings by employer and carrier across fiscal years. These records help identify patterns in carrier exposure and can inform settlement valuations by showing the volume of death claims a particular carrier has handled.
An often-overlooked issue in DBA death cases: the statutory presumption under Section 20(a). The LHWCA presumes that the injury or death arose out of employment. This presumption shifts the burden to the carrier to produce substantial evidence to the contrary. In combat zone deaths, where the mechanism of injury is often an enemy attack, the carrier faces a steep burden to rebut the Section 20(a) presumption.
How Can You Maximize Benefits for Your DBA Client?
Start with the AWW calculation. Fight for inclusion of every compensation component: hazard pay, danger pay, overtime, uplift, and completion bonuses. Document these components from the first pay stub through the last day of employment. The difference between including and excluding hazard pay alone can shift the weekly benefit rate by $500 or more.
Identify all compensable conditions. Polytrauma cases should pursue both scheduled and unscheduled awards concurrently. Hearing loss is a scheduled award that does not require earning capacity proof. TBI and PTSD are unscheduled awards that do. Filing for both simultaneously maximizes the total recovery.
Verify Section 10(f) COLA adjustments annually. Request the carrier's calculation worksheet and compare it to the DOL-published rates. If the carrier has not applied the adjustment, send written demand with the published rate table.
