Healthcare costs continue to climb, prompting employers to evaluate everything from plan design changes to wellness initiatives in an effort to manage spending. While those strategies can play an important role, they often require months or even years before employers realize measurable savings.
Dependent verification audits offer a different approach. Rather than changing benefits or shifting costs to employees, they help employers ensure that only eligible dependents are enrolled in coverage according to the eligibility rules already established in their benefits plan.
The financial impact can be significant. In one recent engagement, ebm helped a global manufacturer generate more than $262,000 in annual healthcare savings, producing a 13.8x return on investment from a single dependent verification audit.
The cost employers often don’t see
Most employers don’t intentionally cover ineligible dependents. These situations usually develop over time as life events occur.
An employee may divorce and forget to remove a former spouse from coverage. An adult child may exceed the plan’s age limit. Other dependents may simply never have provided documentation confirming eligibility during enrollment.
Without a formal verification process, these situations can remain unnoticed for years, allowing unnecessary healthcare costs to accumulate while creating compliance concerns around enforcing plan eligibility rules consistently.
The financial impact of dependent verification
Every ineligible dependent enrolled in a health plan represents additional premium costs and potential claims that the employer never intended to cover.
Because healthcare claims can be substantial, identifying even a relatively small percentage of ineligible dependents can produce meaningful savings. Unlike many cost-containment initiatives, those savings begin almost immediately after coverage is updated and continue into future plan years.
Case study: A 13.8x return on investment
One of ebm’s clients, a leading global supplier of industrial machinery and equipment with more than 15,000 employees worldwide, engaged ebm to conduct a dependent verification audit covering 530 employees and 1,040 enrolled dependents.
Over an eight-week audit, followed by a two-week grace period, employees were asked to provide documentation verifying dependent eligibility.
The results demonstrated how even a relatively small percentage of ineligible dependents can have a meaningful financial impact.
The audit found that 4% of enrolled dependents were ineligible for coverage. Removing those individuals from the health plan generated $262,248 in annual savings, reducing the employer’s annual healthcare spend by approximately 3%.
With an audit investment of $17,730, the employer realized a 13.8x return on investment.
The results also reinforce an important point: employers don’t need widespread eligibility issues to realize substantial value. Even identifying a handful of ineligible dependents can offset the cost of an audit many times over.
Beyond cost savings
While the financial return often drives interest in dependent verification, audits also strengthen the overall integrity of a benefits program.
They help employers consistently enforce the eligibility rules outlined in their Summary Plan Description (SPD), improve the accuracy of benefits data, and demonstrate a commitment to administering health plans fairly across the employee population.
For many employers, an initial audit is only the first step. Ongoing dependent verification helps validate newly added dependents during enrollment, preventing ineligible individuals from entering the plan before coverage begins.
Making dependent verification part of a long-term strategy
Healthcare costs will likely remain one of the largest expenses employers manage each year. Dependent verification doesn’t replace broader benefits strategies, but it can deliver measurable savings while improving plan governance and data accuracy.
As this case study demonstrates, identifying just 4% of dependents as ineligible resulted in more than $262,000 in annual savings and a 13.8x return on investment. For employers looking to better manage healthcare costs without changing plan designs or reducing benefits, dependent verification remains one of the most effective opportunities available.
